The Claim

In obese women, high-dose omega-3 supplementation (4.8 g/day EPA+DHA) is associated with a transient reduction in plasma TNF-α levels during treatment, with this effect reversing after supplementation ceases, while TNF-α gene expression remains suppressed, indicating differential regulation between circulating TNF-α protein and cellular TNF-α mRNA.

How it works
1 study reviewed
In plain English

When obese women take a high dose of omega-3 fish oil supplements, their blood levels of a certain inflammation marker drop while they're taking it, but go back up after they stop. However, their cells still keep the gene for that marker turned down, which means the body is handling the marker in two different ways.

  1. Study: Differential effects of high dose omega-3 fatty acids on metabolism and inflammation in patients with obesity: eicosapentaenoic and docosahexaenoic acid supplementation

    In obese women, taking a high dose of omega-3 fish oil for three months lowered a key inflammation marker in the blood—but only while they were taking it. However, the genes that make that marker stayed quiet even after stopping, meaning the body’s internal instructions changed longer than the blood levels showed.
