Can supplements reverse your age? Can you supplement your way out of aging? Dive into 1,000+ research studies to find out the science behind.

Current AI tools like ChatGPT, Gemini from Google and Copilot from Microsoft might return generic answers to your questions. While these can be a starting point, they often lack the depth and updated references you might crave for your research. 

This practical guide will help you to understand aging, longevity, and all that is involved to “turn back the clock” and to reduce your confusion from reading only ChatGPT answers. We are providing you with science, knowledge, and best of all possibilities.

If you are in the anti aging, longevity or biohacking space, chances are you have heard about Dr David SinclairBryan JohnsonSiim LandDave Pascoe and Dr Peter Attia. Most of them do share many longevity related strategies on their social media accounts. However, their recommendations might be too overwhelming for an average layperson. You should also consult your doctor before starting any new diet and supplement program to ensure safety and suitability for your individual needs.

In September of 2019, the MIT Technology Review published “The Longevity Issue” with a MASSIVE black heading on a snow-white cover and announced, “OLD AGE IS OVER!” and in a font much smaller underneath are the following words: “IF YOU WANT IT.”

1. Vitamin D3: Key Studies

This is one of the most effective supplement combinations based on evidence-based benefits, offering both anti-aging and anti-cancer properties.

Here are key studies on Vitamin D for anti aging and longevity:

Vitamin D

2025 Zhu et al - Vitamin D3 and marine ω-3 fatty acids supplementation and leukocyte telomere length: 4-year findings from the VITamin D and OmegA-3 TriaL (VITAL) randomized controlled trial (The American Journal of Clinical Nutrition)

2024 Ruggiero et al - Targeting the Hallmarks of Aging with Vitamin D: Starting to Decode the Myth (Nutrients

2. Omega-3 and Carotenoids: Key Studies

Omega-3 fatty acids and Carotenoids

Omega-3 fatty acids reduce inflammation, enable the immune system to carry out its tasks, and help the brain and eyes to function properly.

2022 Ogluska et al - Effect of Omega-3 Fatty Acids on Telomeres—Are They the Elixir of Youth (Nutrients)

2021 McBurney et al - Using an erythrocyte fatty acid fingerprint to predict risk of all-cause mortality: the Framingham Offspring Cohort (American Journal of Clinical Nutrition)

3. Magnesium and Molecular Hydrogen

Magnesium

Magnesium is a very important mineral in the human body. Magnesium functions as a cofactor to hundreds of different enzymes, which need magnesium to function properly.

2024 Dominguez et al - Magnesium and the Hallmarks of Aging (Nutrients)

Molecular Hydrogen

Molecular hydrogen is the smallest anti-oxidant.

2022 Fu et al - Role of Molecular Hydrogen in Ageing and Ageing-Related Diseases (PubMed

2023 Artamanov et al - Molecular Hydrogen: From Molecular Effects to Stem Cells Management and Tissue Regeneration (Antioxidants)

Note: Most Molecular Hydrogen tablets uses pure elemental magnesium as its carrier and provides you with approximately 80 mg of magnesium per tablet. So, you receive also highly bioavailable magnesium for a healthy brain, muscles, cells, kidneys, and heart.

4. Glycine

Glycine is an amino acid that occurs naturally in our body. When we age, glycine levels decline. Low glycine levels also have been associated with various aging-related diseases like cardiovascular disease and with type 2 diabetes.

2024 Soh et al - The effect of glycine administration on the characteristics of physiological systems in human adults: A systematic review (GeroScience)

2023 Ceron et al - Glycine: The Smallest Anti-Inflammatory Micronutrient (PubMed).

5. NAC

Researchers at Baylor College of Medicine also looked into supplementation with a combination of glycine and N-acetylcysteine (NAC), two glutathione precursors known as GlyNAC when taken together.

2021 Kumar et al - Glycine and N-acetylcysteine (GlyNAC) supplementation in older adults improves glutathione deficiency, oxidative stress, mitochondrial dysfunction, inflammation, insulin resistance, endothelial dysfunction, genotoxicity, muscle strength, and cognition: Results of a pilot clinical trial
A pilot trial in older humans (Clinical and Translational Medicine).

6. Taurine

2024 Tzang et al - Taurine reduces the risk for metabolic syndrome: a systematic review and meta-analysis of randomized controlled trials (Nature

2023 Singh et al - Taurine deficiency as a driver of aging (Science).

7. CoQ10 and PQQ (Best for Mitochondrial Support and Heart Health)

Coenzyme Q10 (CoQ10) is an antioxidant that your body produces. It plays an essential role in energy production and protects against cellular damage.

2023 Alehagen et al - Effects of an Intervention with Selenium and Coenzyme Q10 on Five Selected Age-Related Biomarkers in Elderly Swedes Low in Selenium: Results That Point to an Anti-Ageing Effect-A Sub-Analysis of a Previous Prospective Double-Blind Placebo-Controlled Randomised Clinical Trial (Cells).

2022 Alehagen et al - Improved cardiovascular health by supplementation with selenium and coenzyme Q10: applying structural equation modelling (SEM) to clinical outcomes and biomarkers to explore underlying mechanisms in a prospective randomized double-blind placebo-controlled intervention project in Sweden (European Journal of Nutrition).

2022 Gherardi et al - CoQ10 and Resveratrol Effects to Ameliorate Aged-Related Mitochondrial Dysfunctions (Nutrients)

2022 Tippairotte et al - Combined Supplementation of Coenzyme Q10 and Other Nutrients in Specific Medical Conditions (Nutrients)

CoQ10 is also part of Dr. David Sinclair’s supplement list.

The interventions testing program (ITP) tested a similar compound, MitoQ (a better absorbable nutrient based on coQ10), and didn’t find a life extension effect (R).

That said, CoQ10 decline as you age and it plays an essential role in energy production and protects against cellular damage. Supplementing with CoQ10 might allow for more physical activity and therefore more likely to have a protective effect than a negative one.

Coenzyme Q10 (CoQ10) and Pyrroloquinoline Quinone (PQQ) are often combined in supplements because they support cellular energy production and mitochondrial health through complementary mechanisms. Their combination is believed to provide greater benefits than either compound alone, especially for energy, cognitive function, and cardiovascular health.

While both PQQ supplements and CoQ10 have benefits for mitochondrial function and energy production, there are some key differences between the two. PQQ is a newer supplement and has been shown to have stronger antioxidant properties than CoQ10. It also has potential benefits for cognitive function and memory. On the other hand, CoQ10 has been more extensively studied and has been shown to have benefits for heart health and exercise performance.

8. Vitamin C

Vitamin C can help to maintain a proper epigenome, especially in combination with another longevity ingredient, alpha- ketoglutarate.

2022 Xu et al - Vitamin C intake and multiple health outcomes: an umbrella review* of systematic reviews and meta-analyses (PubMed)

*Umbrella review: An umbrella review, or a review of reviews, is a systematic review that only considers other systematic reviews as an eligible study type for inclusion. An umbrella review compiles evidence from multiple existing reviews and is one of the highest levels of evidence.

2024 Wang et al - Dietary intake of potassium, vitamin E, and vitamin C emerges as the most significant predictors of cardiovascular disease risk in adults (PubMed)

9. Curcumin (Turmeric)

Curcumin — the main active compound in turmeric — has been shown to possess powerful anti-aging properties, which are attributed to its potent antioxidant potential.

2022 Arslan et al - The golden spice curcumin in cancer: A perspective on finalized clinical trials during the last 10 years (PubMed)


10. Collagen

Collagen is the king of anti-aging, which is why so many youth rejuvenation treatments focus on renewing or revitalizing collagen production in the body — but you can kick start this process without needles, simply by supplementing collagen into your diet.

2023 meta-analysis of 26 RCTs (randomized controlled trials), showed that Hydrolyzed Collagen supplementation significantly improved skin hydration and elasticity compared to the placebo group.

small 2021 randomized, placebo-controlled, double-blind trial with 99 Japanese women between the ages of 35 and 50 concluded that oral collagen supplements helped increase skin hydration.

Conclusion and Take Home Messages

It's important to remember that supplements are not a replacement for a broad comprehensive healthy diet and lifestyle, engaging in regular exercise, and reducing stress. It's always best to talk to your doctor before starting any new supplement program.

Certain supplements may help slow the aging process and promote a long, healthy life. A good anti-aging supplement is one that contains substances that are based on science and that acts on aging mechanisms. This also enables these supplements to have an additional important benefit: synergy.

After all, aging is a complex process caused by various different mechanisms, such as epigenetic dysregulation, mitochondrial dysfunction, and accumulation of proteins.

If you have an anti-aging supplement that only focuses on a single dimension such as “improving mitochondrial health”, you are not addressing other important aging mechanisms, like epigenetic dysregulation or accumulation of proteins.

Therefore, this supplement, even if it could improve mitochondrial health, will have little impact on extending lifespan given it only tackles one facet of the aging process.

As such, it’s very important for a good anti-aging supplement stack or combination to contain substances that act on different aging mechanisms in a synergistic way.

For example, alpha-ketoglutarate (AKG) can maintain the epigenome and improve mitochondrial health. AKG can work together with other substances that improve mitochondrial health, like fisetin and malate, or that improve the epigenome, like NMN and glycine.

But addressing the aging epigenome and mitochondria is not enough. You also need to tackle many other aging mechanisms, like protein accumulation and DNA damage.

So the ideal anti-aging supplement contains not just one or two substances that focus on one aging mechanism (like mitochondrial health or the NAD+ metabolism), but contains many substances that act on many aging pathways, and in a synergistic way. See "Causes and Hallmarks of Aging".
