The Claim

In adults with abdominal obesity and low-grade inflammation, 10 weeks of daily 2.7-gram DHA supplementation reduces C-reactive protein (CRP) by 7.9%, while daily 2.7-gram EPA supplementation reduces CRP by 1.8%, with no statistically significant difference between the two effects.

In plain English

In adults with abdominal obesity and low-grade inflammation, 10 weeks of daily 2.7-gram DHA supplementation lowers C-reactive protein levels by 7.9%, while the same dose of EPA lowers it by 1.8%, with no statistically significant difference between the two.

See the scientific wording

In adults with abdominal obesity and low-grade inflammation, 10 weeks of daily 2.7-gram DHA supplementation reduces C-reactive protein (CRP) by 7.9%, while EPA reduces it by only 1.8%, though this difference is not statistically significant, suggesting DHA may have a modestly stronger anti-inflammatory effect on CRP than EPA.

Why this might work

DHA gets absorbed into fat and immune cells, where it is turned into molecules that stop inflammation. These molecules block a key inflammation switch in the liver, which reduces the production of CRP. At the same time, DHA increases a fat-derived hormone that further calms liver inflammation and clears out leftover debris.

  1. Study: A randomized, crossover, head-to-head comparison of eicosapentaenoic acid and docosahexaenoic acid supplementation to reduce inflammation markers in men and women: the Comparing EPA to DHA (ComparED) Study.

    In people with belly fat and inflammation, taking DHA for 10 weeks lowered a key inflammation marker (CRP) more than taking the same amount of EPA — but the difference wasn't big enough to say for sure it wasn't just luck. Still, DHA did better on other inflammation and heart health measures, so it might be more effective.
