Conclusion The results conforms with enterprise standards

1. Benfotiamine (S-Benzoylthiamine O-monophosphate) is a fat-soluble analog of vitamin B1, which has a higher absorption rate and bioavailability than vitamin B1 and is often used as a food supplement for diabetic complications.
2. Benfotiamine has direct antioxidant ability and can prevent DNA damage.
