What are the benefits of each supplement?
Learn about the benefits of each ingredient below, turn on ‘Geek Mode’ to get technical.
Vitamin D3 K2 Mg
- Healthy heart and cardiovascular system
- Improves mood and brain function
- Aids muscle/joint recovery
- Reduces exercise-induced inflammation
- Longer lifespan
In addition to helping support Vitamin D3, Vit K2 reduces inflammation and lowers the risk of heart disease. Vitamin D3 is essential for bone and muscle health, preventing osteoporosis as well as boosting mood. Vitamin D3 does not work alone, and needs to be combined with Vitamin K2 and Mg to have any effect. In addition to helping support Vitamin D3, Vit K2 reduces inflammation and the risk of heart disease, and Mg supplements also strengthen bones, improve sleep and reduce stress. In addition to helping support Vitamin D3, Magnesium supplements also strengthen bones, improve sleep and reduce stress.
Ca-AKG
- Boosts your energy levels
- Prevents chronic disease
- Extends healthspan
- Enhances athletic performance
Alpha-ketoglutarate (AKG) is a key compound used by cells to generate energy, but your body’s ability to produce it declines with age. Taking Ca-AKG in which AKG is bound to calcium to increase its potency and half-life can reverse these effects, boosting your energy levels, preventing chronic disease and extending healthspan.
Omega 3
- Healthy heart and cardiovasc system
- Improves mood and brain function
- Aids muscle/joint recovery
- Reduces exercise-induced inflammation
- Extends lifespan
There is strong evidence to support that Omega 3 fatty acids, particularly EPA and DHA, are vital for a healthy heart and cardiovascular system. It’s difficult to get enough omega-3 for these benefits through diet alone. Increasing your intake with omega-3 supplements greatly reduces the long-term risk of chronic disease and increases healthspan, while alsoimproving mood, cognitive function and gut microbiome.
Fisetin
- Powerful senolytic, clears away inactive senescent cells
- Reduces inflammation
- Powerful antioxidant
- Reduces risk of cancer and other chronic disease
- Extends lifespan
Fisetin is a polyphenol found in very low amounts in some plants. It is anantioxidant and a powerful senolytic, meaning it can clear away inactive, “zombie” cells which accumulate and cause harm as we age. Taking fisetin can reduce inflammation, reduce risk of cancer and other chronic diseases, and extend lifespan.
Spermidine
- Protects cardiovascular system and brain from age-related degeneration
- Extends lifespan in animal studies
Spermidine is a polyamine that is naturally abundant in humans. Recent research suggests that it plays a key role in aging through its action on the AMPK and mTOR systems and its ability to induce autophagy. Supplementing your spermidine intake can have significant benefits especially for the cardiovascular system and brain. Spermidine has also slowed age-related decline and extended lifespan in animal studies.
Hyaluronic Acid
- Slows skin aging, reducing fine lines and increasing skin moisture
- Prevents joint pain and stiffness, lubricates joints
- Speeds up wound healing
- Reduces inflammation
Hyaluronic acid is a key component of the extracellular matrix that surrounds cells. It lubricates tissues and is crucial to skin and muscle health. Hyaluronic acid supplements have potent anti-aging effects on skin and can also prevent joint pain and lower inflammation.
Berberine
- Nature’s ozempic
- Lowers blood glucose levels/improves insulin sensitivity
- Reduced appetite and increased fullness from meals
- Slows aging
Berberine is a plant-derived compound that has been extracted from bark and used in Chinese and Ayurvedic medicine for centuries. When taken as a supplement it has profound benefits on glucose metabolism, lowering glucose levels and improving insulin sensitivity. Recent research has also shown that it can reduce the risk of cardiovascular disease and lower inflammation. As it is not found in any foods, it can only be taken as a supplement.
Pterostilbene
- 4x better cellular uptake than resveratrol (what our competitors sell)
- Powerful antioxidant and anti-inflammatory properties
- Extends healthspan in animals
- Activates sirtuins, promoting DNA repair
Pterostilbene is found naturally in plants such as blueberries and grapes. It is closely related to resveratrol, a compound that has received a lot of attention as a longevity compound. While resveratrol has failed to show efficacy in recent human trials, pterostilbene is taken up into cells four times more effectively and therefore shows much more promise. It has powerful antioxidant and anti-inflammatory properties and extends healthspan in animals.
Glycine
- Reduce the risk of chronic disease
- Improves sleep
Glycine and N-acetylcysteine (NAC) are both amino acids, the building blocks your body uses to produce proteins. Glycine reduces the risk of chronic disease and improves sleep, while NAC enhances exercise performance and mood. NAC and glycine are both needed to produce glutathione, a powerful antioxidant. Taking both compounds together improves mitochondrial function, muscle strength and inflammation.
NAC
- Enhances exercise performance
- Improves mood and mental health
Glycine and N-acetylcysteine (NAC) are both amino acids, the building blocks your body uses to produce proteins. Glycine reduces the risk of chronic disease and improves sleep, while NAC enhances exercise performance and mood. NAC and glycine are both needed to produce glutathione, a powerful antioxidant. Taking both compounds together improves mitochondrial function, muscle strength and inflammation.
TMG
- Enhances muscle-building
- Reduce the risk of cardiovascular disease by lowering levels of homocysteine
- Healthy liver function and detoxification
- Prevents chronic disease
The process of metabolising NMN supplements causes a depletion in your body’s methyl groups, so taking TMG is an easy way to replace these. In addition, Trimethylglycine (TMG) is also beneficial in its own right, since research suggests it can reduce the risk of cardiovascular disease by lowering levels of harmful homocysteine.
NMN
- Increases energy levels
- Improves athletic performance
- Improves sleep
- Protects against metabolic disorders.
- Preserves cognitive function as you age
NMN is crucial for producing cellular energy, but levels decline with age. NMN supplements provide you with youthful energy in your day-to-day life, while also improving sleep and sports performance. Evidence from animal studies suggests that NMN acts on aging pathways (via sirtuins and mTOR) and can therefore protect against age-related decline and increase lifespan.

Mainstream supplements are typically designed to augment ingredients which you could regularly find in your diet to help you meet your daily recommendations. Longevity molecules are different because:
1) you don’t find any of these ingredients in your regular diet and
2) there are no established daily recommendations of these ingredients.
These ingredients have come out of recent cutting-edge research on how to biologically slow the aging process. There aren’t any government guidelines recommending certain levels of these ingredients to promote health, since they are so new and they target the aging process as a whole rather than focusing on a specific disease. Our ingredients cannot be found in most supermarkets or drug stores.
- At 7.2 g grams per dose, we have the highest amount of pure active ingredients of any other longevity company on the market, so you’re actually getting therapeutic doses that make a difference.
- We have the purest and highest quality ingredients, and provide purity reports and 3rd party Lab Testing as well as sourcing information for all ingredients.
- We don’t mess around with vitamin gummies, green juice blends, or other influencer fads which aren’t backed by science. We only supply the real deal, high quality and therapeutic doses backed by 100+ clinical trials.
- We separate our supplement packs into hydrophobic and hydrophilic to optimize absorption and reduce gastrointestinal upset. This means the ingredients are actually getting into your cells, unlike for many multivitamin companies which just cause you to make expensive pee.
- We have expertly curated our supplement stacks to target all 12 root causes of aging, making you biologically younger on the inside.
Zest’s functional age calculation is the most accurate and holistic biological age score on the market, and the only one which takes into account your cognitive function as well as your physical health. We use a combination of blood biomarkers, digital biomarkers and functional biomarkers (including memory tests) which we run through our machine learning algorithm to give you the most accurate and research-backed biological age measurement yet. Our blood test includes markers for your cholesterol levels, hormone levels, liver enzymes, and other tests grounded in 100+ years of research (the OG science, not just the latest fads). We then add this to our digital biomarkers such as resting heart rate, sleep, mood, VO2 max score, and other metrics which give real insight into your day to day functionality. Finally we include grip strength and some cognitive tests as part of our “functional biomarkers” and together this makes up the data that goes into our functional age algorithm to give you a result for your biological age.
