Do your nails peel faster than you can file them?
ℹ️ Taking magnesium, vitamin C, or iron will only help if you’re deficient.
💊 In one small study (no placebo group), women with brittle nails increased nail thickness by 25% after 6–9 months of 2,500 mcg biotin daily (J Am Acad Dermatol. 1990 Dec).
📣FYI: Biotin may slightly increase the rate of growth in healthy nails, but it won’t further strengthen already healthy nails.
💅 Fun fact: Minoxidil (a hair loss treatment) also speeds up nail growth — though not exactly the intended effect.
🎯Bottom line: Before spending money on nail supplements, rule out nutrient deficiencies first.
