The Claim

Supplementing the diet with 6.26 grams per day of n−3 fatty acids (EPA and DHA) from menhaden oil for six weeks increases plasma levels of malondialdehyde and lipid peroxides in healthy adult men, and this increase is not prevented by concurrent daily supplementation with 900 IU of vitamin E.

Cause and effect
1 study reviewed
In plain English

In healthy adult men, taking 6.26 grams of n−3 fatty acids from menhaden oil daily for six weeks raises levels of malondialdehyde and lipid peroxides in the blood, which are markers of lipid peroxidation, and taking 900 IU of vitamin E daily alongside does not stop this increase.

See the scientific wording

Supplementing the diet with 6.26 grams per day of n−3 fatty acids (EPA and DHA) from menhaden oil for six weeks increases plasma levels of malondialdehyde and lipid peroxides in healthy adult men, indicating elevated lipid peroxidation, and this effect is not prevented by concurrent daily supplementation with 900 IU of vitamin E.

What the research says

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

    This study found that taking a specific fish oil supplement for six weeks increased harmful fat damage in the blood, and taking a high dose of vitamin E at the same time didn’t stop it.
