If you want dedicated energy metabolism and nervous system support, this delivers 100mg of **Thiamine** (Vitamin B1) per tablet — the top of the clinical range. For addressing a potential B1 shortfall, the dose is right where it needs to be.

The form is thiamine hydrochloride, which is the standard supplemental form. It's well-studied and widely used, though your body absorbs only a fraction of high oral doses since thiamine HCl has limited bioavailability at this level. Benfotiamine, a fat-soluble form, would deliver more thiamine to your tissues at the same dose — but it's also more expensive.

This is a single-ingredient, one-tablet-per-day formula that's easy to add to your existing routine. The 100-count bottle gives you over three months of daily use, and the straightforward format means you can pair it with other B vitamins if your needs are broader.
