Vitamin B1, or thiamine, shows up in a lot of supplements. Benfotiamine is a specific form of it, and the difference matters more than you might expect.
Benfotiamine is a fat-soluble derivative of thiamine, which allows it to be absorbed differently than standard water-soluble thiamine, generally resulting in better bioavailability.
Better absorption means more of the nutrient is actually available for your body to use in nerve metabolism and signaling processes, rather than being excreted unused.
NeuroGenica includes benfotiamine specifically for this bioavailability advantage, rather than a cheaper, less absorbable standard thiamine form.
