Anti-Aging Supplements: What Science Actually Says

The anti-aging supplement industry is worth billions, but which supplements actually have scientific backing? This evidence-based review separates fact from fiction.

The Science of Aging

Aging involves multiple mechanisms:

• Cellular senescence
• Telomere shortening
• Mitochondrial dysfunction
• Oxidative stress
• Chronic inflammation

Supplements with Strong Evidence

1. NAD+ Precursors (NMN/NR)

Evidence: Clinical trials have shown that NMN improves physical performance and sleep quality, strength and walking speed, insulin sensitivity, and skin aging [1]. Studies in humans with NMN use 250 mg per day, with research showing NAD+ supplements can improve various health markers and potentially reverse age-related tissue damage.

Dosage: 250-500mg daily Cost: $50-100/month

2. Resveratrol

Evidence: A 2013 review in Ageing Research Reviews suggested that resveratrol mimics the effects of calorie restriction, which is associated with longer lifespan in many species [2]. Recent studies show resveratrol has anti-obesity, cardioprotective, neuroprotective, and anti-aging effects. Some experts believe resveratrol has synergistic effects with NMN. Human Studies: Mixed results, may work better with quercetin Dosage: 500-1000mg daily Cost: $20-40/month

3. Curcumin

Evidence: Powerful anti-inflammatory with over 3000 studies Benefits: Reduces inflammation markers, may protect against age-related diseases Dosage: 500-1000mg with piperine for absorption Cost: $15-30/month

4. Omega-3 Fatty Acids

Evidence: Strong evidence for cardiovascular and brain health Benefits: Reduces inflammation, supports telomere length Dosage: 2-3g EPA/DHA daily Cost: $20-40/month

5. Vitamin D3

Evidence: Deficiency linked to accelerated aging Benefits: Immune function, bone health, longevity Dosage: 2000-4000 IU daily Cost: $10-20/month

Supplements with Moderate Evidence

6. Coenzyme Q10

Evidence: Levels decline with age, supplementation may help energy production Dosage: 100-200mg daily Cost: $25-40/month

7. Alpha-Lipoic Acid

Evidence: Antioxidant that may protect against oxidative stress Dosage: 300-600mg daily Cost: $20-35/month

8. Spermidine

Evidence: Promotes autophagy (cellular cleanup) Dosage: 1-3mg daily Cost: $30-50/month

Supplements with Limited Evidence

9. Collagen Peptides

Evidence: May support skin health, but body produces collagen from amino acids Better Alternative: Focus on vitamin C and protein intake

10. Growth Hormone Secretagogues

Evidence: Limited human studies, potential risks Concerns: May increase cancer risk

Red Flags: Avoid These

• Human Growth Hormone: Dangerous without medical supervision
• Telomerase Activators: Limited evidence, potential cancer risk
• "Fountain of Youth" Blends: Usually overpriced with unproven ingredients
