The Claim

In older adults, biological sex modulates the immune response to omega-3 and protein supplementation, with men exhibiting greater reductions in pro-inflammatory markers (IL-6, CCL-2, HMGB-1) and women exhibiting more consistent reductions in gene expression of IL-6 and IL-1RA.

How it works
1 study reviewed
In plain English

In older adults, men and women respond differently to omega-3 and protein supplements: men show larger decreases in certain blood-based inflammatory markers, while women show more consistent decreases in the activity of specific immune-related genes.

See the scientific wording

In older adults, sex-specific differences in inflammatory responses to omega-3 and protein supplementation are evident, with men showing greater reductions in pro-inflammatory markers (IL-6, CCL-2, HMGB-1) and women showing more consistent reductions in gene expression of IL-6 and IL-1RA, suggesting biological sex modulates the immune effects of nutrition.

Why this might work

In older men, omega-3 fats and protein change the fatty acid makeup of immune cell membranes, which turns down the activity of genes that make inflammatory signals, leading to less of those signals in the blood. In older women, the same nutrients turn down those same genes inside immune cells, but the cells still release similar amounts of inflammatory signals into the blood — so only the gene activity changes, not the blood levels.

  1. Study: Effects of Exercise and Omega-3-Supplemented, High-Protein Diet on Inflammatory Markers in Serum, on Gene Expression Levels in PBMC, and after Ex Vivo Whole-Blood LPS Stimulation in Old Adults

    In older adults, men and women react differently to omega-3 and protein supplements: men had lower levels of certain inflammation markers in their blood, while both men and women had changes in immune cell gene activity — showing that sex matters in how nutrition affects the immune system.
