The discussed study evaluates the impact of omega-3 supplements combined with vitamin D and exercise on biological aging markers among older adults. Although individual and combined treatments showed some protective effects on DNA methylation clocks like PhenoAge, critics highlight limitations such as a small sample size and inadequate power in certain indicators of biological aging. The modest positive effects of omega-3, particularly evident in isolation, raise questions about the robustness and broad applicability of the findings, with some skeptics doubting the conclusion that aging itself is slowed based solely on indirect epigenetic markers.
