Hair Growth Stack
Popular hair-thickness supplements — which actually have support.
Your stack needs work — most goals aren’t well-covered yet.
What's in this stack
- Biotin5/10 evidence
B vitamin popular for hair and nails. The honest verdict: only old, small, mostly uncontrolled trials support firmer brittle nails — there's no good evidence for hair growth unless you're deficient, and high doses skew lab tests.
Typical dose: 2500-5000mcg (2.5-5mg) for hair/nails
- Collagen6/10 evidence
Hydrolyzed peptides that rebuild skin elasticity, reduce joint pain, and strengthen bone density — results build over 8-12 weeks.
Typical dose: 10-15g
- Zinc8.5/10 evidence
Involved in 300+ enzymatic reactions — supports immune defense, testosterone production, wound healing, and sleep quality.
Typical dose: 15-30mg daily
- Saw Palmetto4/10 evidence
The most popular herb for BPH urinary symptoms. The honest verdict: the highest-quality JAMA and Cochrane trials found it no better than placebo, so the evidence nets out weak and mixed.
Typical dose: 320mg standardized extract (85-95% fatty acids)
