Why you'll love it

If you've ever searched for supplements for hair, skin, or nails, biotin was probably the first result. And for good reason — biotin is a key coenzyme in keratin production, the structural protein that makes up your hair, skin, and nails. When biotin levels are low, the effects show up fast: brittle nails, thinning hair, and dry, flaky skin.

Clinical studies show that biotin supplementation improves nail thickness and reduces splitting in people with brittle nails, and supports hair growth rate and thickness. It's particularly effective when hair thinning or nail fragility is related to nutritional deficiency, which is more common than most people realize — especially in those who diet frequently, take certain medications, or have digestive issues that affect nutrient absorption.

Beyond beauty benefits, biotin is essential for macronutrient metabolism. It serves as a cofactor for carboxylase enzymes that help break down fats, amino acids, and glucose. At 1,000mcg, this provides a meaningful dose well above the daily value to support both cosmetic and metabolic benefits.

How much do I really need?

Take one 1,000mcg capsule daily with food. Biotin is water-soluble, so your body will excrete any excess. Important note: high-dose biotin can interfere with certain lab tests (including thyroid and cardiac panels), so inform your healthcare provider of biotin supplementation before blood work.
