The Biotin Synthesis

Biotin Details

Our biotin supplement contains purified biotin made through a synthesis reaction. The process begins with cyclic acid’s conversion to lactone, which is then converted to dibenzyl biotin and rinsed with ethanol to create a crude form of biotin. The crude biotin is further purified, washed with deionized water, and dried to create the final biotin found in our capsules. Our manufacturer, Arizona Nutritional Supplements (ANS), receives the ingredient as a powder to be used as the active ingredient in our product.

Sourced in
Xinchang County, Zhejiang, China
