Omega-3 fish oil supplements could backfire without this ...

What’s Happening

Here’s the thing: Fish oil’s cancer-fighting reputation may hinge on a little-known gene.

Researchers found out that omega-3s like EPA and DHA help curb colorectal cancer only when the enzyme ALOX15 is present. Without it, fish oil sometimes increased tumor growth in mice—especially DHA. (shocking, we know)

The results suggest that not all supplements work the same way, and genetics could determine who truly benefits.

The Details

Science News Omega-3 supplements may only help fight colorectal cancer if the body has the right enzyme to activate them. Without ALOX15, fish oil—especially DHA—could lose its protective power and even fuel tumor growth.
