Ageing is inevitable — but how we age is increasingly within our control. Modern longevity science has moved well beyond skin creams and antioxidant buzzwords. Today, a growing body of clinical research points to specific nutrients and compounds that target the underlying biological mechanisms of ageing: cellular energy decline, oxidative stress, inflammation, collagen loss, and DNA repair.
Here are the most evidence-backed supplements for healthy ageing — and the science behind why they matter.
1. NMN (Nicotinamide Mononucleotide)
NMN is a precursor to NAD+ — a coenzyme that is central to cellular energy production, DNA repair, and gene expression. NAD+ levels decline by approximately 50% between the ages of 40 and 60, and this decline is closely linked to the hallmarks of ageing. NMN supplementation has been shown in human trials to raise NAD+ levels, improve muscle function, and support metabolic health in older adults. It is one of the most exciting compounds in longevity research.
Typical dose: 250–500 mg daily, taken in the morning. Sublingual or liposomal forms offer enhanced bioavailability.
2. Resveratrol
Resveratrol is a polyphenol found in red grape skin that activates sirtuins — a family of proteins involved in cellular repair, inflammation regulation, and longevity pathways. It works synergistically with NMN by activating SIRT1, which requires NAD+ to function. Research suggests resveratrol supports cardiovascular health, reduces oxidative stress, and may mimic some effects of caloric restriction at the cellular level.
Typical dose: 250–500 mg of trans-resveratrol daily, taken with a fat-containing meal for optimal absorption.
3. Collagen Peptides
Collagen production declines by roughly 1% per year from our mid-20s, leading to the visible signs of skin ageing — wrinkles, sagging, and loss of elasticity. Hydrolysed collagen peptides have been shown in multiple randomised controlled trials to improve skin elasticity, reduce wrinkle depth, and increase dermal collagen density after 8–12 weeks of use. They also support joint cartilage and bone density — two areas significantly affected by ageing.
Typical dose: 5–10 g daily of Type I/III hydrolysed collagen peptides. Pair with Vitamin C for optimal synthesis.
4. Coenzyme Q10 (CoQ10)
CoQ10 is a fat-soluble antioxidant that plays a critical role in mitochondrial energy production. Like NAD+, CoQ10 levels decline significantly with age — and are further depleted by statin medications. Supplementation supports cellular energy, reduces oxidative damage, and has been shown to improve cardiovascular function and reduce markers of inflammation in older adults. The ubiquinol form is more bioavailable than ubiquinone, particularly in those over 40.
Typical dose: 100–200 mg of ubiquinol daily, taken with a meal containing fat.
5. Astaxanthin
Astaxanthin is a carotenoid antioxidant derived from microalgae and is considered one of the most potent antioxidants in nature — up to 6,000 times more powerful than Vitamin C in certain assays. It crosses both the blood-brain barrier and the blood-retinal barrier, offering neuroprotective and eye health benefits. Clinical studies show it reduces UV-induced skin damage, improves skin moisture and elasticity, and reduces oxidative stress markers.
Typical dose: 4–12 mg daily, taken with a fat-containing meal.
6. Vitamin D3 + K2
Vitamin D deficiency accelerates several ageing processes, including bone loss, immune decline, and muscle weakness. Adequate Vitamin D levels are associated with longer telomere length — a key biomarker of biological age. Pairing D3 with K2 (MK-7) ensures calcium is properly directed to bones and away from arterial walls, supporting both skeletal and cardiovascular health as we age.
Typical dose: 1,000–2,000 IU Vitamin D3 with 100–200 mcg Vitamin K2 (MK-7) daily.
7. Omega-3 Fatty Acids
Chronic low-grade inflammation — sometimes called "inflammageing" — is one of the primary drivers of age-related disease. Omega-3 fatty acids (EPA and DHA) are among the most potent natural anti-inflammatory compounds available. They support brain health, cardiovascular function, joint mobility, and skin hydration — all of which decline with age. Higher omega-3 index levels are consistently associated with slower biological ageing.
Typical dose: 1,000–2,000 mg of combined EPA/DHA daily from a purified, molecularly distilled fish oil.
8. Magnesium
Magnesium deficiency accelerates cellular ageing by impairing DNA repair mechanisms and increasing oxidative stress. It also supports sleep quality — a critical but often overlooked factor in cellular repair and longevity. Magnesium glycinate or magnesium threonate (which crosses the blood-brain barrier) are the preferred forms for anti-ageing purposes.
Typical dose: 300–400 mg daily, ideally in the evening.
The Longevity Mindset
Anti-ageing supplementation is most effective as part of a broader longevity strategy: regular exercise (especially resistance training), a whole-food diet rich in polyphenols and protein, quality sleep, stress management, and avoiding smoking and excess alcohol. Supplements amplify the results of these fundamentals — they don’t replace them.
The most impactful starting point for most people is the foundational stack: Vitamin D3/K2, Omega-3s, Magnesium, and CoQ10 — before layering in more targeted compounds like NMN and resveratrol.
