How Biotin Works - The Science
Understanding Vitamin B7 (Biotin) in Your Body
Biotin is an essential B-vitamin that plays critical roles in your body's cellular processes:
- Keratin Production: Biotin is essential for keratin synthesis, the primary protein in hair, skin, and nails. Adequate biotin supports stronger, healthier growth of all three.
- Energy Metabolism: Acts as a coenzyme in breaking down macronutrients (carbs, proteins, fats) for energy production. More biotin = better metabolic efficiency.
- Blood Sugar Regulation: Helps maintain healthy blood glucose levels by supporting insulin function.
- Amino Acid Processing: Essential for processing amino acids used in protein synthesis throughout the body.
- Nerve Function: Supports healthy nervous system function and myelin maintenance.
Result: With consistent 10,000mcg daily supplementation, most users report visible improvements in hair thickness, skin clarity, and nail strength within 6-12 weeks.
