Built for nerve health and glucose metabolism, this **Benfotiamine** gives you a full 250mg in one capsule — an effective dose right inside the 80–300mg range used in clinical research. Benfotiamine is a fat-soluble form of vitamin B1 that absorbs far better than standard thiamine, so it reaches the nerve and muscle cells where your body struggles to deliver ordinary B1.

The practical advantage is that a single capsule already lands you in effective territory, so you don't have to stack pills to reach a studied dose. The 10mg of standard thiamine alongside it is minor — your benefit comes from the benfotiamine, the form with the real backing for blood-sugar and nerve support.

If your goal is glucose metabolism or nerve comfort, this is where benfotiamine has its strongest evidence. The label allows up to four capsules daily, but for most people one 250mg capsule is enough.
