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.

Key Benefits

Supports Healthy Blood Sugar Metabolism

Benfotiamine helps the body metabolize glucose and can help maintain healthy blood sugar levels already within the normal range.

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.

Dosage & How to Take

Benfotiamine is typically taken in capsule form. Dosages can vary based on individual needs and health goals.
