The Claim

Inter-individual variability in absolute RRR-α-tocopherol absorption is large across healthy adults, regardless of whether the vitamin E is administered as free phenol, acetate ester, or succinate ester.

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

Description
1 study reviewed
In plain English

Healthy adults absorb RRR-α-tocopherol, a form of vitamin E, to very different degrees, and this variation does not change based on whether the vitamin E is given as free phenol, acetate ester, or succinate ester.

See the scientific wording

Inter-individual variability in absolute RRR-α-tocopherol absorption is large across healthy adults, regardless of whether the vitamin E is administered as free phenol, acetate ester, or succinate ester.

Why this might work

People absorb vitamin E differently because their intestines take up and package it into fat-carrying particles at different rates, depending on their genes and how their bodies handle fats.

What the research says

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

    The study found that people absorb different types of vitamin E supplements in similar ways, which means the form of the supplement matters more than the claim suggests. It shows that not everyone absorbs it wildly differently—contrary to what the claim says.
