Description
D-Biotin Product Overview
D-Biotin (C10H16N2O3S) is a white crystalline powder that is slightly soluble in water. Only the D-isomer is biologically active, so specifications control specific rotation and related substances, typically with an assay of 98.5–101.0%.
Pharmaceutical companies use pure D-biotin in tablets, capsules and injections, while producers of nutritional products use it in multivitamins, gummies and powders, under the regulations of each market. Similarly, food producers use it in infant formula and fortified foods. Because doses are only micrograms, many users also buy diluted 1% or 2% forms, which appear on our Vitamin H (Biotin) page.
In addition, cosmetic formulators use it in hair and nail care products. Other B vitamins in our range also include Vitamin B1 Thiamine Hydrochloride and Nicotinamide (Vitamin B3).
