Buying Guide

How to Choose a Skin, Hair & Nail Supplement

Beauty-from-within supplements have gained solid RCT support for specific outcomes — wrinkle depth, nail brittleness, hair density — when correctly formulated.

Ingredients with clinical evidence

  • Hydrolyzed collagen peptides (10–15 g/day): Multiple meta-analyses confirm improvements in skin elasticity, hydration, and wrinkle depth after 8–12 weeks.
  • Biotin (2.5–5 mg/day): Well-supported for brittle nails. Less evidence for hair growth in biotin-replete individuals.
  • Silica (as MMST, 5–10 mg/day): Small RCTs show improvement in nail and hair strength.
  • Zinc (15–30 mg/day): Deficiency causes hair loss, skin issues, and slow wound healing.
  • Hyaluronic acid (120–240 mg/day): Small RCTs show skin hydration improvements.
  • Vitamin C (500–1000 mg/day): Cofactor for collagen synthesis.

Red flags to avoid

  • Non-hydrolyzed collagen (poor absorption)
  • Proprietary "beauty blends" hiding individual doses
  • Mega-dose biotin (>5 mg) can interfere with thyroid and cardiac lab tests
  • Unspecified collagen sources (look for marine, bovine, or chicken on the label)

What we rank on

Collagen type and hydrolysis quality (type I+III for skin, type II for joints), dose fidelity to RCTs, bioavailability enhancers where relevant, and third-party testing. We also value transparency on collagen source and manufacturing.

Our Methodology

Skin, hair, and nail supplements are scored on collagen hydrolysis (degree of enzymatic breakdown affects absorption), dose adequacy vs. clinical trial protocols, biotin levels (noting lab-test interference), and third-party testing. Vitamin C co-factors and silica inclusion earn bonus points.
