Summary of "9 Supplements With STRONG Evidence Of Benefit"
Key Supplements With Strong Evidence of Benefit and Their Uses
1. Creatine
- Well-known for muscle performance and recovery.
- Safe with no link to hair loss, kidney issues, dehydration, or muscle cramping.
- Emerging evidence supports cognitive benefits, especially in memory performance for older adults and during stress (e.g., sleep disruption).
- Typical dose: 5 grams daily, including non-workout days.
2. Protein Powder
- Important for maximizing and maintaining muscle strength to reduce all-cause mortality.
- Recommended intake:
- 1.6 g/kg body weight/day for general adults.
- 2 g/kg for older adults due to muscle loss and absorption issues.
- Best consumed in multiple meals spaced 3-4 hours apart.
- Protein powders are convenient, highly bioavailable, and should be free from added sugars and salts.
- Higher protein intake is associated with longevity benefits in humans, despite some animal study controversies.
3. TMG (Trimethyl Glycine)
- May accelerate ATP recycling and enhance muscle protein synthesis, but benefits are only seen when combined with exercise.
- Potential brain health benefits by lowering homocysteine levels, a risk factor for Alzheimer’s disease.
- Typical dose: 500 mg to 1 g daily.
4. Multivitamin and Mineral Supplements
- Useful due to widespread micronutrient deficiencies (e.g., vitamins B3, D3, K2, zinc, magnesium).
- Large studies show benefits on global cognition with daily use.
- Should complement, not replace, a healthy diet.
- Magnesium form preference: magnesium taurate for potential longevity benefits.
5. Omega-3 Fatty Acids
- Observational studies link fish consumption to reduced cognitive decline, but randomized controlled trials (RCTs) show no cognitive benefit from supplements.
- Strong evidence supports cardiovascular benefits, notably a 28% reduction in heart attack risk.
- Typical dose: 1-2 capsules daily.
6. Psyllium Husk
- A high-fiber supplement that supports gut bacteria and immune function.
- Helps reduce LDL cholesterol and promotes satiety.
- Can be added to smoothies or shakes.
7. Collagen Peptides
- Shown to reduce wrinkles (~8%) and improve skin hydration and elasticity.
- May enhance wound healing better than some protein sources.
- Typical dose: 10-15 g daily.
- Benefits may be additive to adequate protein intake.
8. Hyaluronic Acid
- Multiple trials show significant wrinkle reduction (~18%).
- No safety concerns in long-term human studies.
- Molecular weight form likely not critical.
- Typical dose: 200 mg daily.
9. Low-Dose Melatonin
- Helps improve sleep onset and quality when taken 1-2 hours before bedtime.
- Recommended low dose: up to 300 micrograms to mimic physiological levels.
- Also has antioxidant and anti-inflammatory effects, possibly beneficial in aging.
- Evidence for benefits beyond sleep (e.g., mortality reduction) is currently lacking.
10. N-Acetylcysteine (NAC)
- Supports glutathione production, a key antioxidant that declines with age.
- May improve mitochondrial function and oxidative balance in older adults.
- Early research stage; dose around 1 g after age 45.
- Often combined with glycine (found in collagen supplements) and TMG for synergistic effects.
Additional Wellness & Productivity Tips
- Consistency in supplementation is important (e.g., creatine daily regardless of workout).
- Protein intake should be spaced throughout the day for optimal muscle synthesis.
- Supplementation should complement a balanced diet, not replace whole foods.
- Timing and dosing matter, especially for supplements like melatonin.
- Exercise is necessary to realize benefits from some supplements (e.g., TMG).
- Be cautious of supplement quality and avoid those with excessive additives.
