Fish oil supplements beat oily fish at reducing harmful blood vesicles

Fish oil supplements, delivering higher EPA doses, significantly reduced the number and procoagulant activity of extracellular vesicles—unlike oily fish. This suggests EPA, not DHA, may drive cardiovascular benefits linked to EV function.

7-day creatine ‘wash-in’ boosts muscle mass in women — but not long-term, study reveals

A 7-day creatine monohydrate wash-in increased lean body mass in females, especially in the trunk, but adding creatine to resistance training didn’t boost muscle gains beyond training alone. Higher doses or hydration tracking may be needed for long-term effects.

Sticking to Life’s Essential 8 slashes cancer risk, major study shows

Long-term adherence to the American Heart Association’s “Life’s Essential 8” lifestyle score significantly reduces the risk of overall and site-specific cancers. Stable high LE8 scores over four years were linked to notably lower risks of lung, breast, liver, and colorectal cancers in a large Chinese cohort study.
