At 400 IU of natural **d-alpha-tocopherol**, this hits a full antioxidant dose for cellular and liver protection, right at the top of the typical supplemental range. The natural d- form matters here: your body absorbs about twice as much as it would from synthetic vitamin E, so the label dose is the dose you actually get.

It also adds a small 10mg blend of mixed tocopherols — gamma, delta, and beta — which broadens antioxidant coverage beyond what alpha-tocopherol offers alone. It's still primarily an alpha product, but that addition rounds out the spectrum.

Worth knowing: 400 IU sits right at the threshold where some long-term studies have flagged a small risk increase with high-dose vitamin E. You're at that line, not above it, so this is a sensible ceiling to hold rather than exceed if you take it daily.
