Each capsule delivers 100mg of **Benfotiamine** — a fat-soluble form of vitamin B1 that absorbs up to 5x better than standard thiamine because it bypasses the intestinal transport bottleneck. At one capsule you're already within the clinical range (80–300mg), and the label's four-capsule daily recommendation puts you at 400mg, well above what most studies use for supporting healthy blood sugar metabolism and protecting nerve tissue from glycation damage.

The 25mg of standard **Thiamine Hydrochloride** per capsule adds a water-soluble baseline, giving your body both absorption pathways. At the full daily dose of 100mg thiamine HCl, you're at the top of the typical B1 supplement range — though benfotiamine is doing the heavy lifting here for energy and nerve support.

The tradeoff is pill burden. Four capsules a day is the label recommendation, and skipping down to one or two still keeps you in a useful range for benfotiamine — but you'd lose the higher-end thiamine coverage. If you're taking this specifically for nerve health or blood sugar support, the full four capsules is where the research points.
