Benfotiamine CAS 22457-89-2 | High Bioavailability Vitamin B1 Derivative

Ordinary Vitamin B1 features low absorption and poor bioavailability, resulting in weak product effect and low repurchase rate in finished supplements.

Benfotiamine is a fat-soluble Vitamin B1 analog with greatly improved absorption rate. It has become a popular premium ingredient for eye health, metabolic care and diabetic care supplements in global markets.

Key Product Advantages

Benfotiamine provides much higher bioavailability than common thiamine. It absorbs faster and more completely for better formula performance.

It is metabolized safely in the human body without brain accumulation, and excreted naturally with urine, making it ideal for long-term health supplements.

It targets high-demand markets including retina protection, microvascular repair and metabolic health maintenance.
