The Claim

Daily supplementation with 900 IU of vitamin E (dL-α-tocopherol acetate) for six weeks significantly increases plasma α-tocopherol concentration in healthy adult men and does not reduce the elevation in plasma malondialdehyde and lipid peroxides induced by concurrent n−3 fatty acid supplementation.

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Taking 900 IU of vitamin E daily for six weeks raises levels of vitamin E in the blood of healthy adult men, but it does not lower the increase in certain oxidative stress markers caused by taking omega-3 fatty acids at the same time.

See the scientific wording

Daily supplementation with 900 IU of vitamin E (dL‐α‐tocopherol acetate) for six weeks significantly increases plasma α-tocopherol concentration in healthy adult men but does not reduce the elevation in plasma malondialdehyde and lipid peroxides induced by concurrent n−3 fatty acid supplementation.

What the research says

1 study
  1. Study: Lipid peroxidation during n−3 fatty acid and vitamin E supplementation in humans

    Taking 900 IU of vitamin E daily for six weeks raised vitamin E levels in the blood, as expected. But it didn’t stop the increase in harmful fat damage caused by fish oil supplements — so vitamin E didn’t protect against that side effect.
