Your A to Z Guide for Understanding Longevity Supplements

      Longevity supplements are gaining popularity as people seek to enhance their health and extend their lifespan. These supplements offer essential nutrients and compounds that may promote overall well-being. However, they are not standalone solutions but should complement a balanced diet and a healthy lifestyle. Informed decisions are crucial when choosing supplements, considering ingredients, and consulting with healthcare professionals. This trend aligns with geroscience's goal to delay ageing and increase a healthy lifespan, emphasising the potential "longevity dividend." As nutraceutical  advancements like calorie restriction mimetics and senolytics emerge, informed use of supplements becomes integral to a holistic health strategy. (Vaiserman & Lushchak, 2017) 

      The Science Behind Longevity Supplements 

      Longevity supplements are dietary supplements formulated with ingredients believed to support healthy ageing and increase lifespan. These supplements often contain antioxidants, vitamins, minerals, senolytics, and other nutrients that promote overall health and well-being. The purpose of these supplements is to provide nutrient-rich support that may help delay the onset of age-associated decline, improve cognitive function, enhance immune system function, etc. Scientifically-backed supplements have undergone rigorous testing and research to validate their claims and demonstrate their potential benefits for longevity and overall health. Here is a list of science backed longevity supplements for healthy ageing:

      NMN (Nicotinamide Mononucleotide)

      Nicotinamide mononucleotide (NMN) plays a crucial role as a precursor to NAD+, a vital molecule required for energy, metabolism, DNA repair, and cell survival. As NAD+ levels decline with age, supplementation with NMN offers a potential way to increase NAD+ levels in the body. Moreover, studies suggest NMN supplementation may be more efficient at raising NAD+ levels and serving as a SIRT activator. Research shows promise for improving insulin sensitivity, enhancing energy metabolism, and potentially preventing age-related decline in mitochondria.


      Spermidine, a natural polyamine found in cells, is vital for cellular health. It mimics fasting by promoting autophagy  and protecting DNA and cells. Research suggests it triggers autophagosome formation, cleansing cellular debris in various organisms. This "cellular housekeeping" rejuvenates cells, improving mitochondrial function and reducing inflammation, potentially extending lifespan and overall health.

      TMG (Trimethylglycine)

      TMG, also known as trimethyl glycine or betaine anhydrous, is a molecule that provides methyl groups (-CH3) for vital functions, playing crucial roles in DNA repair, gene expression, protein function, and metabolism. By donating methyl groups, TMG aids in converting the amino acid homocysteine to methionine, potentially lowering the risk of heart disease. Additionally, TMG supports elevated athletic performance and  digestive health. Ongoing research indicates that TMG may also support liver function and cognitive function in older adults.


      Trans-Resveratrol, a potent antioxidant found in grapes, acts as a shield by neutralising free radicals and protecting cells from oxidative damage. Ongoing research investigates its potential lifespan benefits in humans, while trans-resveratrol shows promise for heart health by potentially reducing blood pressure and enhancing blood flow. Moreover, its anti-inflammatory properties may offer benefits for conditions such as arthritis and managing blood sugar levels. It also promotes calorie efficiency, modulates epigenetic changes, and addresses age-related brain decline.

      Calcium Alpha-Ketoglutarate (Ca-AKG)

      Calcium Alpha-Ketoglutarate (Ca-AKG) is a molecule gaining interest for its potential to enhance cellular health and strengthen bones. It functions within the Krebs cycle, readily donating a fragment for energy and converting it into other key compounds such as glutamine and glutamate, which may enhance cellular energy efficiency. While research is ongoing, a study found that Ca-AKG supplementation significantly reduced biological age, delayed the onset of age-related diseases, and improved muscle function.


      Fisetin, a natural compound found in strawberries,  is a potent senolytic activator. Research indicates that fisetin is a powerful antioxidant, combating harmful free radicals. It may also help clear out senescent cells that accumulate with age and contribute to ageing. Moreover, fisetin shows promise in supporting memory, protecting brain function, and potentially enhancing cellular stress resistance, thereby potentially slowing down age-related decline.


      Quercetin, a natural antioxidant and anti-inflammatory compound found in fruits, is currently being studied for its potential to promote longevity. It acts as a shield against free radicals, eliminates senescent cells, and relieves allergies. Additionally, quercetin combats chronic inflammation, a low-grade inflammation linked to many age-related problems. By slowing cellular decline, decreasing the risk of chronic diseases, and promoting overall cellular health.


      Trans-Pterostilbene, found in blueberries, acts as an antioxidant with potential benefits for longevity, heart health, and brain function. Its high bioavailability and prolonged effects  offer enhanced protection against cellular damage and support various longevity-related processes, including antioxidant and anti-inflammatory actions. Moreover, it promotes sirtuin activation and enhances calorie efficiency. Studies suggest it could enhance mitochondrial function and resilience, potentially delaying age-related decline.
