Ranked by expert consensus across 113+ longevity protocols. Last updated March 2026.
Top 10 Supplements for Longevity
Vitamin D3 (5000 IU)
High-potency vitamin D3 supplement providing 5000 IU per serving to support optimal blood levels. Essential for immune function, bone health, and mood regulation. One of the most widely recommended supplements among longevity researchers due to widespread deficiency.

supplements
CoQ10 (Coenzyme Q10)
Coenzyme Q10 is a naturally occurring antioxidant that plays a critical role in mitochondrial energy production. CoQ10 levels decline with age, making supplementation increasingly relevant for supporting cardiovascular health, cellular energy, and overall vitality. The ubiquinol form offers superior bioavailability compared to ubiquinone.
CoQ10 (Coenzyme Q10)
supplements
NAD+ Precursor (NMN/NR)
NAD+ precursor supplement in NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside) form. Supports cellular energy production and DNA repair by boosting NAD+ levels, which naturally decline with age. A cornerstone supplement in many longevity-focused protocols.
NAD+ Precursor (NMN/NR)
supplements
Glutathione (Liposomal)
Liposomal glutathione supplement for enhanced absorption of the body's master antioxidant. Glutathione plays a critical role in detoxification, immune support, and protecting cells from oxidative stress. Liposomal delivery bypasses digestive breakdown for greater bioavailability.
Glutathione (Liposomal)
supplements
Vitamin K2 (MK-7)
Vitamin K2 in the MK-7 form supports proper calcium metabolism, directing calcium into bones and teeth while preventing arterial calcification. Works synergistically with vitamin D3 to optimize bone mineral density and cardiovascular health. Essential for activating proteins involved in blood coagulation and vascular protection.

supplements
Spermidine
Spermidine is a naturally occurring polyamine that declines with age and is a potent inducer of autophagy, the cellular recycling process linked to longevity. Found in foods like wheat germ, aged cheese, and natto, spermidine supplementation has been associated with improved cardiovascular health and cognitive function in clinical studies.

Spermidine
supplements
Quercetin
Quercetin is a plant flavonoid with potent antioxidant and anti-inflammatory properties. Supports immune function, cardiovascular health, and has been studied as a senolytic agent that helps clear damaged senescent cells. Often combined with vitamin C or bromelain to enhance absorption.

supplements
Sulforaphane / Broccoli Sprout Extract
Concentrated sulforaphane from broccoli sprout extract, a potent activator of the body's Nrf2 antioxidant pathway. Supports detoxification, reduces inflammation, and has been extensively studied for its cellular protective properties. Best absorbed when taken with a source of myrosinase.

supplements
Taurine
Taurine is a conditionally essential amino acid concentrated in the brain, heart, and muscles. A landmark 2023 study in Science found that taurine levels decline with age and that supplementation extended lifespan in animal models. It supports cardiovascular function, mitochondrial health, and exercise performance.

Frequently Asked Questions
What is the number one anti-aging supplement?
There is no single "best" anti-aging supplement, but NAD+ precursors (NMN/NR) and omega-3 fish oil appear most frequently in longevity expert protocols. Vitamin D and spermidine are also top contenders based on research evidence.
Do longevity supplements actually work?
Several longevity supplements have strong clinical evidence. Omega-3 fish oil reduces cardiovascular risk, vitamin D supports immune function, and spermidine has been shown to induce autophagy. However, supplements work best alongside exercise, sleep, and a whole-food diet.
What supplements does Bryan Johnson take for longevity?
Bryan Johnson's Blueprint protocol includes a comprehensive stack focused on anti-aging. His protocol emphasizes extra virgin olive oil, dark chocolate, collagen peptides, and blueberry powder alongside targeted supplementation. See his full protocol page for the complete list.
