The Claim

The extent of absorption of RRR-α-tocopherol from acetate and succinate esters is not significantly different in healthy adults, although the acetate ester exhibits a slightly higher initial absorption rate.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Description
1 study reviewed
In plain English

In healthy adults, the total amount of RRR-α-tocopherol absorbed from acetate and succinate esters is the same, but the acetate form is absorbed a little faster at the beginning.

See the scientific wording

There is no significant difference in the extent of absorption of RRR-α-tocopherol from acetate and succinate esters in healthy adults, although the acetate ester may have a slightly higher initial absorption rate.

Why this might work

When you swallow vitamin E in acetate or succinate form, enzymes in your gut break off the acetate or succinate group, releasing the same active vitamin E molecule. Once freed, this molecule enters your bloodstream at the same rate and amount regardless of which ester it came from, even though the acetate version breaks down a little faster at first.

  1. Study: Biokinetics in humans of RRR-alpha-tocopherol: the free phenol, acetate ester, and succinate ester forms of vitamin E.

    This study found that your body absorbs vitamin E just as well whether it comes in acetate or succinate form — even if acetate might go into your blood a tiny bit faster at first, both end up giving you about the same amount of vitamin E overall.
