Benfotiamine
Benfotiamine is a synthetic, lipid-soluble form of vitamin B1 (thiamine) that achieves significantly higher blood and tissue levels compared to standard thiamine supplements. Originally developed in Japan, it has been widely used in Europe for decades to address conditions linked to thiamine deficiency. It is particularly studied for its effects on nerve function, blood sugar metabolism, and protection against advanced glycation end products (AGEs).
