NAD+ Precursors (NMN & NR)

NAD+ (nicotinamide adenine dinucleotide) declines with age, affecting cellular energy production and DNA repair. NMN and NR are precursors that may restore NAD+ levels.

  • NMN (250-1000mg/day): Shows impressive results in animal models — improved metabolism, endurance, and insulin sensitivity. Human trials are ongoing but limited. A 2022 study showed improved aerobic capacity in recreational runners.
  • NR/Niagen (300-1000mg/day): More human data than NMN. Proven to raise blood NAD+ levels. Less clear whether raising blood NAD+ translates to meaningful anti-aging outcomes in humans.

Honest assessment: The science is exciting but early. If you can afford it and want to be an early adopter, these are among the more scientifically plausible longevity supplements. But don't expect proven anti-aging results yet.

Collagen Peptides

Collagen supplements have moved from beauty trend to one of the better-supported anti-aging categories, particularly for skin and joint health.

  • Type I & III (10-15g/day): Multiple RCTs show improved skin elasticity, hydration, and reduced wrinkle depth after 8-12 weeks. Hydrolyzed collagen peptides are the best-studied form.
  • Type II (40mg/day, undenatured): UC-II collagen has specific evidence for joint comfort through immune modulation. Different mechanism than Types I/III.

Source quality matters: Marine collagen (fish) has slightly better bioavailability than bovine. Look for products with vitamin C added — it's a required cofactor for collagen synthesis.

CoQ10 & Ubiquinol

CoQ10 is a mitochondrial antioxidant that declines with age and statin use. It's one of the most evidence-supported anti-aging supplements.

  • Ubiquinol (100-200mg/day): The reduced, active form. Better absorbed than ubiquinone, especially over age 40 when conversion efficiency drops.
  • Ubiquinone (200-400mg/day): Standard CoQ10. Still effective but requires higher doses for equivalent blood levels.

Who should take it: Anyone over 40, anyone on statins (which deplete CoQ10), and anyone with cardiovascular risk factors. One of the few supplements with both mechanistic rationale and consistent clinical support.

Resveratrol & Polyphenols

Resveratrol got famous from the "French paradox" — the observation that French people had lower heart disease despite high fat intake. The supplement reality is more complicated.

  • Trans-Resveratrol (250-500mg/day): Activates sirtuin pathways in cell and animal studies. Human evidence for lifespan extension is absent. May have modest cardiovascular and anti-inflammatory benefits.
  • Pterostilbene (50-100mg/day): Similar mechanism to resveratrol but 4x better bioavailability. Growing human evidence for lipid and blood sugar support.

Honest take: Resveratrol supplements are a bet on mechanistic science that hasn't fully translated to human outcomes yet. Not harmful, potentially beneficial, but far from proven for actual life extension.

Buying Tips for Anti-Aging Supplements

Start with what has the strongest human evidence: CoQ10/ubiquinol and collagen peptides. These have the most clinical support across the broadest populations. NAD+ precursors and resveratrol are reasonable additions if budget allows, but manage expectations — the longevity field is still young. Avoid any product that claims to "reverse aging" — that's marketing, not science.

How It Works

1

Prioritize the Proven

CoQ10 and collagen peptides have the strongest human evidence. Start here before exploring cutting-edge compounds.

2

Choose Active Forms

Ubiquinol over ubiquinone (after age 40). Hydrolyzed collagen peptides over gelatin. Trans-resveratrol over cis-resveratrol. The form determines how much your body actually uses.

3

Stack Strategically

CoQ10 + collagen + vitamin D3/K2 is a well-supported foundation. Add NAD+ precursors or resveratrol if budget allows and you're comfortable with earlier-stage evidence.

4

Track Biomarkers

Get baseline blood work (CRP, lipids, fasting glucose, vitamin D). Retest after 3-6 months. Objective data beats subjective feelings when evaluating supplement efficacy.

Sytropin — Support Natural Growth Hormone Production

Growth hormone is one of the most significant hormones that declines with age. Sytropin is an oral spray that uses amino acid precursors and growth factors to support your body's natural HGH production — without needles or prescriptions.
