Best heart and longevity supplements for men

NAD+ declines by 50% between age 40 and 60, impairing mitochondrial function, DNA repair, and sirtuin activity. CoQ10 follows the same trajectory and accelerates with statin use. These compounds do not reverse ageing, but they address the measurable cellular decline that begins in your late thirties.

What the evidence says

A 2020 clinical trial in Nature Metabolism found 500mg daily NMN increased blood NAD+ levels by 38% in healthy middle-aged adults. Ubiquinol (active CoQ10) at 200mg daily improved left ventricular ejection fraction in patients with chronic heart failure by 5.2% versus placebo in a landmark 2008 trial in the Journal of Cardiac Failure.

Frequently asked questions

Is NMN worth taking?

The human evidence is growing but still early. NAD+ precursors (NMN and NR) consistently raise blood NAD+ levels in humans. Whether that translates to longevity benefits in healthy adults remains unproven. At current prices, the most pragmatic approach is to address lifestyle factors first (sleep, training, diet) and add NMN at 500mg/day if budget allows.

Do I need CoQ10 if I take statins?

Yes. Statins inhibit the mevalonate pathway, which is the same pathway used to synthesise CoQ10 endogenously. All statin users should supplement CoQ10. Use ubiquinol (the active form) rather than ubiquinone if you are over 40, as conversion efficiency declines with age.

What is the best way to take resveratrol?

Resveratrol has extremely poor bioavailability as a standalone powder. Take it with a fat source (olive oil, avocado) and pair with quercetin, which inhibits the enzyme that clears resveratrol from the bloodstream. Many longevity practitioners combine 500mg resveratrol with 500mg NMN taken in the morning.
