Quick Navigation by Goal

๐Ÿ˜ด Best Supplements for Sleep

#1 PICK โ€” Most Evidence

Magnesium Glycinate 400mg

โ˜…โ˜…โ˜…โ˜…โ˜…

The most bioavailable magnesium form. Studies show it reduces sleep onset time by 17 minutes and improves sleep quality scores. Also calms anxiety and relieves muscle tension โ€” triple benefit for sleep.

Why it works:
  • โ€ข Activates GABA receptors (your brain's natural "off switch")
  • โ€ข 67% of adults are magnesium deficient
  • โ€ข Glycinate form avoids the digestive upset of cheaper forms

L-Theanine 200mg

Amino acid from green tea. Promotes alpha brainwave activity โ€” relaxed but alert. Pairs well with magnesium or take alone 30 min before bed. No drowsiness the next morning.

โšก Best Supplements for Energy & Focus

#1 ADAPTOGEN

Ashwagandha KSM-66 600mg

KSM-66 is the most studied ashwagandha extract. Clinical trials show 27% reduction in cortisol, improved VO2 max by 7%, and better memory scores vs placebo. Not a stimulant โ€” it works by reducing stress load.

โœจ Best Supplements for Skin & Hair

BEST SELLER โ€” Skin + Joints

Vital Proteins Collagen Peptides

Hydrolyzed collagen is absorbed 1.5ร— more efficiently than food collagen. A 2019 double-blind trial showed 28% improvement in skin elasticity after 8 weeks at 10g/day. Dissolves in hot or cold liquid, tasteless.

Pro tip: Take with Vitamin C โ€” it's required for collagen synthesis. A morning smoothie with collagen + vitamin C + berries is the most efficient delivery.

Biotin 5000mcg + B Complex

Most effective for hair growth when combined with a full B complex rather than biotin alone. Deficiency causes hair thinning and brittle nails โ€” common in people on restrictive diets.

~$15โ€“22 Amazon โ†’

๐Ÿ›ก๏ธ Best Supplements for Immunity

Vitamin D3 + K2 (5,000 IU)

D3 without K2 can cause calcium to deposit in arteries instead of bones. K2 directs it correctly. Essential in winter โ€” 80% of people in northern climates are deficient.

Amazon โ†’

Zinc Bisglycinate 25mg

Bisglycinate is 43% more bioavailable than zinc oxide (used in cheap supplements). Critical for immune response, wound healing, and testosterone production.

๐Ÿ”ฌ Longevity Supplements Worth Knowing

NMN 500mg (Nicotinamide Mononucleotide)

NAD+ precursor studied by David Sinclair at Harvard. NAD+ declines 50% by age 50, impairing cellular energy production and DNA repair. NMN supplementation in trials restored NAD+ to younger levels. High-end pick โ€” expect $40โ€“80/month.

Omega-3 (EPA/DHA 2000mg)

The most-studied supplement in history. Reduces triglycerides by up to 30%, supports brain health, reduces inflammation. Key: look for 1000mg+ combined EPA+DHA per serving, not just "fish oil 1000mg" (often only 300mg active).
