Longevity & AgingNew Study Questions Whether Omega-3 Supplements Actually Protect Your Brain
A new study using Alzheimer's Disease Neuroimaging Initiative data found that omega-3 supplementation did not protect against cognitive decline, and may be linked to concerning brain imaging results. Dr. Brad Stanfield explores why this matters, examining the well-known problem of omega-3 supplement oxidation — fish oil degrades quickly and many pharmacy-bought products are already rancid. He contrasts these findings with the VITACOG trial, which showed that omega-3s combined with B vitamins did reduce brain atrophy. Stanfield also references the VITAL trial on cardiovascular outcomes. The takeaway is nuanced: omega-3s may still be beneficial, but supplement quality is critical, and the wrong product could be actively harmful rather than protective.
