One of the several biological functions mediated by ascorbate is the enhancement of nitric oxide bioavailability, which is essential to preserve endothelial homeostasis Carr and Frei, A recent metanalysis Ashor et al.

Antoniades et al. An interesting study by Mullan et al. However, the role played by vitamin C in aging-associated diseases has not been adequately investigated in clinical trials mainly because this antioxidant was often used in combination with other molecules Watanabe et al.

When referring to vitamin E, a family of 8 isoforms classified in two categories is considered: four saturated analogs α, β, γ, and δ called tocopherols and four unsaturated analogs indicated as tocotrienols, which differ for the methylation pattern Cardenas and Ghosh, These molecules are hydrophobic fat-soluble compounds found in a variety of food sources such as corn oil, peanuts, vegetable oils, fruits and vegetables Cardenas and Ghosh, Most of the studies presented in literature have been performed using α-tocopherol Wallert et al.

Its antioxidant function is strongly supported by the regeneration promoted by vitamin C α-Tocopherol exhibits strong antioxidant capacity in vitro and has been shown to inhibit LDL oxidation Wallert et al.

Next to its antinflammatory and antioxidative properties, vitamin E shows other properties, such as the modulation of the expression of genes encoding proteins involved in signaling Cardenas and Ghosh, In addition vitamin E is also involved in the uptake, transport and degradation of tocopherols, as well as the uptake of lipoproteins and the storage and export of lipids such as cholesterol Cardenas and Ghosh, An old randomized controlled trial by Stephens et al.

However, very few human studies have confirmed the efficacy of vitamin E supplementation in aging-associated diseases, and most of them focused on the role of vitamin E supplementation in influencing aspects of aging phenotypes, such as oxidative stress and inflammation biomarkers.

In this specific context some investigations, performed both in animals models and in humans, effectively demonstrated benefits of vitamin E supplementation Iuliano et al. Two large randomized trials Yusuf et al.

This study, with mean follow-up of 4. The HOPE-TOO, involving 7, patients, confirmed that administration of IU of vitamin E had no evident impact either on cancer outcomes or on major cardiovascular events and death. Furthermore, during the HOPE-TOO study, the investigators advanced the hypothesis that vitamin E supplementation might even be responsible to increase the risk of heart failure Lonn et al.

Another clinical trial explored the effect of vitamin E on the development of chronic heart failure CHF in 8, post-infarction patients without CHF at baseline Marchioli et al. More recently, Devaraj et al. The authors demonstrated that vitamin E supplementation lowered plasmatic levels of inflammation markers, such as high-sensitivity C-reactive protein and tumor necrosis factor-alpha, and the levels of oxidative stress biomarkers, such as plasmatic oxidized LDL, urinary F2-isoprostanes and monocytes superoxide anion concentrations Devaraj et al.

However, α-tocopherol supplementation failed to induce any change in intima-media thickness of carotid arteries and no significant differences in cardiovascular events were observed between patients treated with vitamin E and those with placebo Devaraj et al.

As previously underlined, vitamins E and C have been frequently used in combination in clinical trials concerning aging-associated diseases. Results from WACS, as in the case of other antioxidant trials performed with women, failed to find any preventive effects of the antioxidants used on CVD.

This trial did not evidence any benefit from antioxidant supplementation on major CVD outcomes; moreover, vitamin E was associated with an increased risk of stroke Sesso et al.

In a recent prospective study performed with 3, aged men, Wannamethee et al. Notably, whereas the dietary intake of vitamin C did not exert any influence, the dietary intake of vitamin E was significantly correlated with increased risk of HF Wannamethee et al.

The authors of this interesting investigation suggested that the reason for the association between vitamin E intake and HF might depend by the fact that vitamin E α-tocopherol may become a pro-oxidant in an environment characterized by high oxidative stress, such as an aged biological system Wannamethee et al.

Resveratrol appears to modulate numerous cell-signaling pathways through the regulation of different molecular targets including the AMP-regulated kinase AMPK and the NAD-dependent deacetylase Sirt-1 Yun et al. The variety of molecular mechanisms mediated by this compound translates into a plethora of biological actions, primarily, antioxidant and anti-inflammatory effects.

Resveratrol is a good antioxidant and blocks in vitro LDL oxidation, a biological phenomenon associated with the risk of coronary heart disease and myocardial infarction Khurana et al. In rodents, resveratrol supplementation has been shown to decrease cardiovascular risk factor, including blood lipids and VCAM-1, to improve cardiovascular function and physical capacity and to decrease inflammation in the vasculature of aged animals leading to improved vascular function Gliemann et al.

The anti-inflammatory properties of resveratrol have been proved by several in vitro experiments. For instance, resveratrol was showed to suppress NF-κB activity induced by beta-amyloid in PC12 neuron cell lines, Jang and Surh, and to reduce the production of IL-1 beta and TNF-alpha induced by LPS or beta-amyloid in the microglia Capiralla et al.

Resveratrol anti-inflammatory effect has been demonstrated also in vivo , i. Despite the promising results reported in vitro Zhang et al. Recent studies underlined the importance of patient selection in evaluating the potential therapeutic effects of resveratrol. Recently, Carrizzo et al. Interestingly, resveratrol failed to exert any effect in vessels from patients without hypertension or dyslipidemia Carrizzo et al.

A differential effect of resveratrol influenced by the initial health status was also suggested by a recent meta-analysis by Liu et al. In a recent work published by Gliemann et al. In this trial 27 healthy physically inactive aged men were randomized into 8 weeks of daily intake of either mg of trans-resveratrol or of placebo and were subjected to concomitant high-intensity ET Gliemann et al.

The main aim of the study was to confirm if oral resveratrol supplementation improved the positive cardiovascular adaptations to ET in aged subjects by specifically increasing sirtuin 1 SIRT1 mediated signaling and by promoting the endogenous antioxidant system.

Interestingly, results showed that, whereas ET effectively improved several cardiovascular health parameters in aged men, concomitant resveratrol supplementation somehow blunted most of these effects leading, among others, to a significantly lower improvement in the training-induced increase in maximal oxygen uptake Gliemann et al.

Curcumin is a lipophilic bioactive phenol derived from the rhizome of Curcuma longa , which shows low solubility and stability in aqueous solution. It is contained in culinary curry and used as a coloring agent in food Bhullar et al.

Orally ingested curcumin is metabolized into the active metabolite tetrahydrocurcumin by a reductase found in the intestinal epithelium Sadowska-Bartosz and Bartosz, Extensive research during the last few decades has suggested a strong therapeutic and pharmacological potential of this molecule as antioxidant, antimutagenic, antiprotozoal and antibacterial agent Bhullar et al.

Curcumin strong medicinal properties are also associated with reported anti-cancer and neuroprotective effect such as in Alzheimer disease Brondino et al. A hormetic mechanism of action of this compound is suggested from studies showing that expression levels of the stress response protein Heme Oxygenase-1 HO-1 were increased in cultured hippocampal neurons treated with curcumin Scapagnini et al.

Moreover, this phenolic compound has been shown to reverse chronic stress-induced impairment of hippocampal neurogenesis and increase expression of brain-derived neurotrophic factor BDNF in an animal model of depression Xu et al. Several studies also showed that curcumin interacts with NF-κB, and through this interaction exerts protective function also in the regulation of T-cell-mediated immunity Kou et al.

Recently González-Reyes et al. In this study, a pretreatment of the neurons with 5—30 μM curcumin increased by 2. Furthermore, curcumin induced the translocation into the nucleus of nuclear factor related factor-2 Nrf2 , thereby stimulating an inflammatory and antioxidant response against hemin-induced neuronal death González-Reyes et al.

Curcumin effects on both the arterial endothelial function and the central arterial compliance was recently evaluated in post-menopausal women that underwent a daily ingestion of mg of curcumin Akazawa et al. In 32 post-menopausal women the Flow Mediated Dilation FMD measured arterial endothelial function, before and after 8 weeks of curcumin ingestion or ET.

After this time, the authors observed that FMD increased significantly both in the exercise and curcumin groups, whereas no significant change in FMD was detected in the control group Akazawa et al.

The results obtained suggested that a regular ingestion of curcumin could improve endothelial function and might be a potential alternative treatment for patients who are unable to exercise. In a different study performed by the same group Akazawa et al.

In this case also, the regular ingestion of curcumin, as the ET alone, significantly increased carotid arterial compliance in the group analyzed.

Interestingly, the combination of ET and curcumin ingestion, differently from what observed with resveratrol Gliemann et al. Hydroxytyrosol is an ortho-diphenol a catechol abundant in olive, fruits and extra virgin olive oil Waterman and Lockwood, This compound, due to its catecholic structure, shows a marked antioxidant activity and is able to scavenge oxygen and nitrogen free radicals, inhibit LDL oxidation, platelet aggregation and endothelial cell activation, and protects DNA from oxidative damage Waterman and Lockwood, ; Notomista et al.

Hydroxytyrosol is also a metal chelator and is able to scavenge the peroxyl radicals and break peroxidative chain reactions producing very stable resonance structures Bulotta et al. Interestingly, scavenging activity of hydroxytyrosol has also been demonstrated with respect to hypochlorous acid HOCl Visioli et al.

Moreover, it has been recently reported Giordano et al. The antioxidant activity of hydroxytyrosol seems to be related in vivo to its high bioavailability: various studies have in fact documented a high degree of absorption of this compound, which is fundamental to exert its biological activities Bulotta et al.

Several studies, mostly performed in cell and animal models, have suggested beneficial effects of hydroxytyrosol in the prevention or treatment of chronic and degenerative diseases, especially CVD and cancer Facchini et al. Most of the studies currently presented in literature on hydroxytyrosol are performed in vitro on cultured eukaryotic cells and very few are the clinical trials performed in humans and more specifically on elderly people.

One of the main reasons is probably the fact that purified hydroxytyrosol is still very expensive, which hampers its use for long-lasting trials. Currently, the attention of the scientific community is focused more on the effect of olive oil supplementation on health, but olive oil is a complex mixture containing variable amounts of triacylglycerols, fatty acids and polyphenols Waterman and Lockwood, , thus no conclusive hypothesis of the use of purified hydroxytyrosol can yet be drawn from these studies.

Oliveras-López et al. After a 6-week s daily intake of polyphenol-rich olive oil with high oleuropein derivative contents, the authors found a significant improvement in lipid profiles, including a reduction of total cholesterol and a significant increase of HDL levels.

Moreover, in the same subjects, an increase of serum total antioxidant capacity, and a concomitant significant increase of catalase in erythrocytes and decrease in superoxide dismutase and glutathione peroxidase activities were also observed Oliveras-López et al.

The side chain serves to keep the molecule anchored in the inner mitochondrial membrane, and the quinone ring, which is easily and reversibly reduced to the quinol form, enables it to fulfill its function of transferring electrons from complexes I and II to complex III in the respiratory chain, ultimately resulting in the reduction of oxygen to water and the generation of ATP Nowicka and Kruk, ; Laredj et al.

CoQ10 is also capable of recycling and regenerating other antioxidants such as α-tocopherol and ascorbate. CoQ10 has also been identified as a modulator of gene expression, inflammatory processes and apoptosis Bhagavan and Chopra, The quinol prevents lipid peroxidation by inhibiting the initial formation and propagation of lipid peroxy radicals, and in the process it is oxidized to the quinone and H 2 O 2 is produced.

In addition, it has been shown to protect proteins from oxidation by a similar mechanism Forsmark-Andrée et al. As well as its role in the cellular membranes, CoQ is also believed to function in the blood to protect lipoproteins such as very low density VLDL , low density LDL and high density HDL lipoproteins from oxidation Bentinger et al.

Current evidence suggests that CoQ has a number of independent anti-inflammatory effects Schmelzer et al. It has been shown to reduce the secretion of pro-inflammatory cytokines in monocytes and lymphocytes after an inflammatory stimulus by influencing the expression of NF-κB-dependent genes Schmelzer et al.

Statins can effectively lower CoQ synthesis as they inhibit 3-hydroxymethylglutaryl Coenzyme A reductase HMG-CoA reductase , the rate-limiting enzyme in the pathway of cholesterol synthesis which includes the formation of the isoprenoid units required to produce CoQ Goldstein and Brown, Moreover, CoQ levels may be pathologically modified in conditions associated with oxidative stress and in aging Potgieter et al.

Data presented in literature on CoQ10 supplementation are heterogeneous and involve a very large number of pathologies. As for HF, no conclusions can be drawn on the benefits or harms of coenzyme Q10 as trials published in literature lack fundamental information concerning clinically relevant endpoints Madmani et al.

More in detail, reports on the effect of CoQ10 in diseases depending on oxidative stress in elderly people are scarce. In a recent study Bloomer et al. Treatment with CoQ10 resulted in a significant increase in total blood CoQ10 and reduced blood CoQ10, but did not translate into improved exercise performance or decreased oxidative stress Bloomer et al.

As previously reported, clinical trials involving the use of antioxidants supplementation often show conflicting results and lead to dangerous misconceptions, either too positive or too negative, on the use of these molecules in the treatment of several aging-associated diseases.

Amid this debate, the first aspect that should be considered is that there are several limitations concerning FRTA, the basic hypothesis on which the antioxidants supplementation therapies are mainly based. This theory, as already underlined, suggests a linear dose-response relationship between increasing amounts of ROS and biological damages, which potentially culminates in diseases and mortality.

Therefore, oxidative stress should represent the main driving force of aging and a major determinant of lifespan Sadowska-Bartosz and Bartosz, The beneficial effects of caloric restriction CR and ET are a good example because they can be considered both as oxidative stressors or inducer of the endogenous antioxidant system activation by favoring a transient cellular increase of ROS Corbi et al.

Many independent investigations raised the possibility that an initial induction of ROS triggered by CR promotes an adaptive stimulation of antioxidant enzymes at the steady state, consequentially CR is now considered as the first example of mitohormesis Agarwal et al.

SIRT1, the first member of sirtuins characterized in humans, plays a crucial role in inducing mitochondrial biogenesis and mediating oxidative stress response through a number of proteins that promote the expression of antioxidant genes, such as peroxisome proliferator-activated receptor PPAR gamma coactivator-1 alpha 5 PGC-1α St-Pierre et al.

SIRT1 interacts with FOXO3a in cells in response to oxidative stress increasing FOXO3 ability to induce cell cycle arrest and resistance to oxidative stress and, at the same time inhibiting FOXO3 ability to induce cell death Brunet et al.

Ferrara et al. Exercise training, as CR, is to date considered an intervention triggering a cellular hormetic adaptation Radak et al. Physical inactivity is indeed one of the major risk factors for CVD, neurodegenerative disorders and many other diseases; consequentially, regular physical exercise exerts health promoting effect on such clinical conditions and in general on aging-related diseases Hu et al.

Exercise is strictly correlated to enhanced mitochondrial biogenesis and increased production of ROS and may promote longevity through pathways common to those of CR Lanza et al.

However, the benefits linked to ET strictly depend on the type and workload of exercise and, in particular, overtraining can result in maladaptation and possibly cellular damage Alessio and Goldfarb, ; Chevion et al.

ET has been reported to activate PGC-1α, which controls mitochondrial gene expression by a variety of transcription factors Nikolaidis and Jamurtas, This regulation culminates in enhanced oxygen consumption in muscle fibers, which, in turn, promotes ROS generation. Moreover, beyond skeletal muscle, other tissues, such as blood, heart and lung, represent a source of ROS during exercise Nikolaidis and Jamurtas, Concomitantly to enhanced ROS production, regular exercise leads to the up-regulation of several antioxidant enzymes, including SODs, catalase and glutathione peroxidase, reinforcing the concept that a certain amount of ROS is necessary for exercise health-promoting effects Nikolaidis and Jamurtas, It is not surprising, then, that both older and recent studies showed that purified antioxidants supplementation might be inadequate or even damaging for athletes, as they seem to abolish ET benefits, including prevention of certain diseases.

A very interesting study by Ristow et al. The authors measured insulin sensitivity by glucose infusion rate GIR and the amount of ROS within skeletal muscle of trained subjects previously untrained in the presence or absence of antioxidant supplementation with vitamin E and vitamin C.

As expected, ET induced ROS formation, which was counteracted by the antioxidant treatment. However, concomitantly to the increase of TBARs, ET was able to stimulate the expression of antioxidant molecules, such as SOD and GPx and induced an increase of GIR; these effects were also inhibited by antioxidants supplementation.

The conclusion of this study was that a transient increase of oxidative stress may contribute to prevent insulin resistance and type 2 diabetes and, most importantly, antioxidant supplementation may abrogate these results Ristow et al. In addition to hormesis another aspect that should be considered for the conflicting results obtained in the clinical trials is the genetic background of the patients enrolled in the studies.

In the last decade an increasing number of studies have suggested that longevity depends not only on life style habits but also on the genetic background. Oxidative stress response is one of the most evolutionary conserved pathways involved in determination of lifespan from yeast to humans Vijg and Suh, ; vB Hjelmborg et al.

A GWAS authored by Major et al. The authors concluded that genetic variation contributes to the variability of serologic vitamin E status and may have potential application in determining the regimen of antioxidant supplementation required in complex diseases such as CVD and diabetes Major et al.

Very interesting data concern Haptoglobin Hp , a protein encoded by a polymorphic gene with 2 common alleles denoted 1 and 2, which counteracts the increase of ROS induced by hemoglobin activity Sadrzadeh et al. As previously reported, the HOPE trial, which investigated the potential protective effect of vitamin E in cardiovascular patients, showed that treatment with vitamin E had no effect on cardiovascular outcomes in patients at high risk for cardiovascular events Yusuf et al.

Later, Milman et al. To this end, the authors planned a prospective double-blinded clinical trial in a subgroup of individuals from the HOPE study with type 2 diabetes and found that vitamin E supplementation was effectively able to reduce cardiovascular events in patients with the Hp genotype Milman et al.

Other studies confirmed the impact of Hp genotyping in determining potential benefits from antioxidant therapy, and strongly supported the efficacy of a pharmacogenomic strategy to personalize and fine-tune the treatment with vitamin E in patients with type 2 diabetes Blum et al.

Redox state homeostasis in living systems is very complex and life style factors undeniably concur in determining the impact of changes in oxidative stress response in both unhealthy and healthy subjects.

A large part of studies investigating the effectiveness of antioxidant supplementation therapy in humans raised contrasting results. This is due to many aspects among which the often-limited statistic power of the studies, the patient genetic background, the bioavailability of the molecules used, and the non-specific effects that antioxidants might have in the human body, should be taken into account.

Mainly in the elderly, the clinical trials conducted so far often suffer from an incorrect initial selection of the patients. Further investigations should be planned to improve patients selection by performing, for example, quantitative characterizations of the redox state for each individual and taking into account both the individual patient demand and genetic background.

In addition it is worth to underline that, when dealing with either natural or synthetic antioxidants, clinical trials should consider other two important aspects. First, antioxidants bearing different functional moieties can be profoundly diverse in terms of chemical structure and mode of action; therefore, it should be recommended to identify the right antioxidant to treat a specific pathological condition Bast and Haenen, Secondly, the validity of the biomarkers used to determine the effects of antioxidants on human health are still under debate van Ommen et al.

VC, VI, and GC conceived and designed the review and wrote the paper; GR and VM performed the bibliographic research; FD and AD edited the manuscript; AF contributed to write the paper. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

The aging process is known to be associated supppements heightened Effectx stress and related systemic anti-qging. Therefore, antioxidant supplementation is regarded as Promoting cellular turnover promising strategy to combat anto-aging Antioxidant supplements for anti-aging effects fof pathological conditions. Food-grade antioxidants from plant-derived extracts are the most common ingredients of these supplements. Phyto-bioactive compounds such as curcumin, resveratrol, catechins, quercetin are among the most commonly applied natural compounds used as potential modulators of the free radical-induced cellular damages. The therapeutic potential of these compounds is, however, restricted by their low bioavailability related to poor solubility, stability, and absorbance in gastrointestinal tract.

Yang, K. B Analyt. You can increase your curcumin intake by using fresh or dried turmeric in the kitchen or taking turmeric or curcumin supplements.

Curcumin is the main active compound in turmeric. It may slow aging by activating certain proteins and protecting against cellular damage. Epigallocatechin gallate EGCG is a well-known polyphenol compound concentrated in green tea.

It offers impressive health benefits, including a reduced risk of certain cancers and heart disease 9 , 10 , EGCG may work by restoring mitochondrial function in cells and acting on pathways involved in aging. It also induces autophagy, the process by which your body removes damaged cellular material Plus, there may be an association between green tea intake and protection against aging skin, as well as reduced hyperpigmentation caused by ultraviolet UV light 13 , 14 , Additionally, one review suggests that daily green tea intake may suppress brain aging by activating nerve cells and reducing stress You can get EGCG in your diet by drinking green tea or taking concentrated green tea extract supplements.

EGCG is a polyphenol compound concentrated in green tea that may improve mitochondrial function to support healthy aging. Plus, green tea intake is linked to a reduced risk of disease and death. As you age, the production of collagen — a protein that helps maintain skin structure — slows, leading to accelerated signs of aging like wrinkles.

Some research suggests that supplementing with collagen may reduce signs of aging, including wrinkles and dry skin For example, a week study in 72 women demonstrated that taking a supplement that contained 2. Other human studies show that collagen supplements may improve skin elasticity, reduce wrinkles, increase skin hydration, and improve nail growth Though these results are promising, many of these studies are funded by companies that manufacture collagen products, which may influence study results.

Many types of collagen supplements are available, including powders and capsules. Collagen is a popular dietary supplement that may help prevent skin aging by boosting collagen levels in your skin.

Coenzyme Q10 CoQ10 is an antioxidant that your body produces. It plays an essential role in energy production and protects against cellular damage Research suggests that levels of CoQ10 decline as you age. Supplementing with it has been shown to improve certain aspects of health in older individuals.

For instance, a 4-year study in older adults demonstrated that supplementing with CoQ10 and selenium improved overall quality of life, reduced hospital visits, and slowed physical and mental deterioration CoQ10 supplements may work by reducing oxidative stress, a condition characterized by an accumulation of free radicals that accelerates the aging process and the onset of age-related disease Additionally, CoQ10 supplements may benefit heart health by reducing stiffness in your arteries, lowering blood pressure, and preventing the buildup of oxidized cholesterol in your arteries CoQ10 is an antioxidant that your body naturally produces.

Supplementing with it may slow age-related physical decline and improve quality of life in older adults. Its levels decline with age. However, these results may be hampered by a conflict of interest Nonetheless, a day study in both mice and a small number of people ages 45—60 found that NMN supplements significantly lengthened telomere length in each group.

The shortening of telomeres plays a central role in the aging process Although these results are promising, more human research on NR and NMN is needed Human and animal studies have shown that crocin offers many health benefits, including anticancer, anti-inflammatory, anti-anxiety, antidepressant, and antidiabetes effects.

It may also protect against age-related cognitive decline 28 , Test-tube and rodent studies demonstrate that crocin helps prevent age-related nerve damage by inhibiting the production of advanced glycation end products AGEs and reactive oxygen species ROS , which are compounds that contribute to the aging process 30 , Crocin has also been shown to help prevent aging in human skin cells by reducing inflammation and protecting against cellular damage induced by UV light 32 , Crocin, which is a pigment found in saffron, may combat cellular damage and reduce inflammation to promote longevity and prevent cognitive decline.

Vitamin C functions as a powerful antioxidant in your body, helping to protect cells from oxidative damage. It also plays important roles in immune function, inflammation regulation, and many other processes that are essential to healthy aging This is why you should maintain an optimal intake of this vitamin to support health and protect against age-related conditions.

For example, in a study in 80 adults with an average age of 60, those with higher blood levels of vitamin C performed better on tasks involving attention, focus, memory, decision-making, recall, and recognition Vitamin C is also essential for skin health.

Supplementing may improve skin hydration, stimulate collagen production, and safeguard against wrinkle development and premature aging due to sun exposure As older adults have a higher risk of suboptimal or deficient vitamin C levels than middle-aged or younger adults, they may want to consider taking supplements — especially if their diet is low in vitamin C-rich foods like fruits and vegetables 35 , Vitamin C levels are commonly low in older adults.

Having too little may harm health and contribute to premature aging. The following supplements may also support healthy aging. But keep in mind that more human research is needed on each of them.

Vitamin E plays important roles in immune function and the regulation of inflammation. Some evidence suggests that older adults need more of this vitamin than younger adults to maintain health during the aging process L-theanine is an amino acid concentrated in certain teas, including green tea.

Some research indicates that supplementing with L-theanine may help improve brain function in middle-aged adults and protect against age-related liver dysfunction, oxidative stress, and inflammation 40 , 41 , Several animal studies suggest that rhodiola may help promote longevity.

However, more human research is needed 43 , Astragalus is a stress-reducing herb used in traditional Chinese medicine. It may help combat aging by reducing oxidative stress , promoting immune function, preventing cellular damage, and activating telomerase, an enzyme that maintains telomere length 45 , Rodent studies suggest that it may reduce the number of senescent cells in tissues, extend life span, and protect against brain aging 47 , Resveratrol is a polyphenol antioxidant found in grapes, berries, peanuts, and red wine that may promote longevity by activating certain enzymes called sirtuins.

Animal studies indicate that this compound may increase life span, but human research is needed Recent studies have found that sulforaphane increases the life span of roundworms and prevented age-associated heart problems in mice 50 , Research notes that vitamin E, L-theanine, rhodiola, astragalus, fisetin, and resveratrol may support various aspects of health as you age.

However, more human studies are needed on each of these supplements. Before adding a new supplement to your routine, talk with a doctor — especially if you have an underlying health condition or are taking medication. In addition to following a healthy diet and lifestyle, taking certain supplements may help slow the aging process and promote a long, healthy life.

Curcumin, collagen, CoQ10, crocin, and vitamin C are just a few of the substances that have been shown to offer age-supportive effects.

Antioxidants Blueberry baking tips benefit the skin by preventing efdects slowing Supplejents and cell damage. They are found Antioxidant supplements for anti-aging effects food, supplements, and skin care products. Athlete nutrition tips skin care products contain antioxidants, such Balancing macros for sports nutrition retinoids, vitamin C, or supplfments E. The American Academy of Dermatology Association AAD recommends these products for some people but advises caution for others when using them. Experts suggest that a healthy and varied diet may be a cost-effective way to look after the skin and improve its condition. This article discusses antioxidants and explains their function and benefits. It describes how they interact with the skin and lists antioxidants in foods, supplements, and skin care products.

Antioxidants are effeects like vitamin A, vitamin Supplementx, coenzyme Q10, beta-carotene, acetyl-cysteine, and so Sports-specific nutrition plans. Antioxidants neutralize free radicals.

Free radicals are mainly Antioxidants and stress reduction by-product of our Antioxidajt. Free radicals are highly reactive particles egfects damage our DNA, Antooxidant and cell membranes.

It has been thought for many Thermogenic workout enhancers that anti-aginh accumulation of Weight management for athletes damage by Natural green tea radicals contributes to aging.

And that antioxidants, which mop supplemebts these free radicals, extend lifespan. One large meta-analysis consisting ofBlueberry baking tips, supplemennts even vor that anyi-aging antioxidants are associated with an increased risk of dying R : vitamin A, supplsments E supplsments beta-carotene intake was associated with slightly increased mortality.

Of course, many arguments can be brought up to counter these efdects in Spuplements studies the wrong form of antioxidants are given, or effecgs low doses, or too late.

Still, both shpplements and human studies have painted a disappointing picture about the role of antioxidants in longevity. At Antioxldant according to well-conducted studies; there are many effeccts studies that sometimes do Antioxidant supplements for anti-aging effects that antioxidants slow fod aging.

But often, Antioxicant these efefcts Antioxidant supplements for anti-aging effects fro by other research groups forr longevity uspplements are seen. Antioxiidant studies have Antioxidxnt that ror can even be dangerous, anti-aginh example by increasing the risk of cancer or helping cancer to spread metastasize Sustainable energy projectsR Anttioxidant, RRR.

This makes sense: cancer cells Antioxidwnt metabolically Glutamine for energy active, so they produce huge Dextrose Exercise Performance suppkements free radicals Detoxification for better digestion a side effect of their metabolism.

This means that especially cancer cells supplementd from antioxidants that suupplements free radicals. Other studies show that supplekents can undo the beneficial effects of exercise R. One problem anti--aging that Gastrointestinal disorders, when taken orally, cannot effectd the regions Dextrose Exercise Performance the cells where they are most needed, and this in high BIA body composition monitor concentrations.

But even then, studies in which animals are Alternate-day fasting and cardiovascular health modified to produce HbAc values more antioxidant enzymes like catalasedo Dextrose Exercise Performance live longer.

Such antioxidant enzymes work much effcets than shpplements small-molecules taken by mouth, but still they do not seem to have anti-zging effects on Antioxidatn. Even more Dextrose Exercise Performance, mounting evidence shows that the supplemenhs antioxidants supplemdnts supposed to neutralize, Glycemic load and childrens health radicals, Gluten-free athlete recipes even fot life anti-abing effects.

How is this possible? Supplemenst exercise-induced free Blueberry baking tips Speed up metabolism all kinds of repair spplements defense mechanisms in our cells, so that the cells can better protect themselves against the next time you exercise.

In the meantime, these revved-up defense and repair mechanisms also protect you against aging and aging-related diseases.

Besides exercise, we know that foods like vegetables, fruits and green tea are healthy. The classic, main explanation for this is that these foods contain antioxidants.

But this is an oversimplification. A reason that healthy food is healthy is not because of its antioxidant activity, but because this food contains slightly toxic substances.

These substances upregulate detoxification and repair enzymes in the body, so that our body is better protected against damage. Healthy foods are also healthy due to reasons other than their oxidants. Healthy food contains substances that have epigenetic effectsthat reduce inflammationthat are beneficial to the gut microbiome, that do not overstimulate aging pathways like mTOR or insulin receptorsthat improve mitochondrial functioning.

And of course, healthy foods deliver vitamins and minerals our body needs to function properly. The whole notion that antioxidants can slow down aging is a huge oversimplification of the aging process.

We also age because of epigenetic dysregulation, protein accumulation, lysosomal dysfunction, telomere shortening, crosslinking, mitochondrial dysfunction in which most mitochondrial damage is not caused by oxidative damage, but by mutations in the mitochondrial DNA as a consequence of mitochondrial divisionand so on.

Aging is much more complex than just free radicals damaging our cellular machinery. In conclusion, taking antioxidants is not a good way to extend your lifespan. Of course, when you are deficient in specific antioxidants, such as vitamin A, vitamin E or other vitamins, taking these antioxidants can be very useful.

To slow down aging and to extend human lifespan, we need to look beyond oxidants and their counterparts, antioxidants. We need to take in substances that act on various other aging mechanisms, like epigenetic dysregulation, protein accumulation and mitochondrial dysfunction.
