Summary

ALOX15 Research Findings

University of Michigan and MD Anderson Cancer Center link ALOX15 to omega-3s.
In mice lacking ALOX15, fish oil may raise colon tumor risk.
EPA (eicosapentaenoic acid) is more effective than DHA (docosahexaenoic acid) when ALOX15 is present.
About 19 million adults in the U.S. use fish oil; the study calls ALOX15 screening before EPA/DHA and boosting ALOX15 in cancer cells.

Summary

EPA/DHA Cancer Findings

Evidence shows inconsistent effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) supplementation on cancer risk.
Large clinical trials examining fish oil and cancer have yielded inconclusive results.
Overall, findings underscore the need for further research to clarify the supplements’ role in cancer prevention.
The evidence does not currently support a clear cancer-prevention recommendation for EPA and DHA supplementation.
