This product provides 160 mg of Benfotiamine, a fat-soluble derivative of thiamin (Vitamin B1). Benfotiamine is widely recognized by nutritionists and in online reviews for its superior bioavailability compared to traditional water-soluble thiamine forms like thiamine hydrochloride or mononitrate. This enhanced absorption allows it to cross cell membranes more effectively, making it particularly beneficial for supporting nerve health, blood sugar metabolism, and other thiamin-dependent bodily functions. The 'double strength' claim is relative to standard lower dose Benfotiamine products, offering a robust dose for therapeutic use.
