Functions

Physiological Functions & Industry Application Logic

D-Biotin acts as the indispensable coenzyme of carboxylase in all organisms, participating in core metabolic pathways of fat, carbohydrate and protein, with verified multi-scenario physiological benefits supported by global nutritional research:

Core Energy & Nutrient Metabolism Regulator D-Biotin catalyzes carboxylation reactions, accelerating fatty acid synthesis, gluconeogenesis and amino acid turnover. Biotin deficiency directly causes metabolic disorders, fatigue, skin inflammation and growth retardation, making it a mandatory fortification ingredient for multi-vitamin formulas.

Hair, Nail & Skin Beauty Nutrient It stimulates keratin synthesis in hair follicles, nail matrix and epidermal cells, effectively improving hair loss, thinning hair, brittle nails, rough skin and seborrheic dermatitis. It is the star functional raw material for anti-hair-loss and brightening cosmetic series.

Human Growth & Developmental Support Essential for infant growth, pregnancy nutrition and elderly metabolic maintenance; widely added in infant formula, prenatal supplements and daily wellness tablets to prevent biotin deficiency symptoms.

Livestock & Aquatic Breeding Booster Supports animal fur, hoof and reproductive health, reduces livestock hair loss and low egg yield, improves feed conversion ratio and young animal survival rate in poultry, swine and aquatic feed formulas.

Sports Nutrition Assistant Optimizes lipid metabolism for fitness crowds, relieves exercise-induced fatigue and supports muscle repair after high-intensity training.

Key Property Reminder: D-Biotin has excellent thermal stability under neutral & weak acid environments, but avoid long-term contact with strong alkali and oxidants to prevent activity decline.
