Benfotiamine (Active B1)
A fat-soluble, highly bioavailable form of Vitamin B1.
Also known as: S-benzoylthiamine O-monophosphate
Overview
Benfotiamine is a synthetic, fat-soluble derivative of thiamine (Vitamin B1). Its superior bioavailability allows it to reach higher levels in the blood and tissues compared to standard thiamine. It is primarily used to support healthy blood sugar metabolism and protect against advanced glycation end products (AGEs), which are implicated in diabetic complications.

Protects Against Advanced Glycation End Products (AGEs)
It helps inhibit the formation of AGEs, which are harmful compounds that can damage cells and contribute to diabetic complications.
Promotes Nerve Health
Benfotiamine has been studied for its potential to support nerve health, particularly in individuals with diabetes.
Antioxidant Properties
It has antioxidant effects that help protect cells from oxidative stress.
