Each morning, millions reach for a small capsule carrying a quiet hope — that the ocean's chemistry might shield the aging mind from its own unraveling.

Consumers may reduce or discontinue fish oil supplement purchases, leading to decreased household spending on preventive health products. This could shift spending toward alternative Alzheimer's prevention strategies or proven treatments, affecting consumer confidence in supplement efficacy claims.
Regulators may strengthen requirements for supplement manufacturers to substantiate health claims with clinical evidence. FDA could increase scrutiny of cognitive health marketing claims. May prompt policy discussions on supplement labeling standards and advertising regulations to prevent misleading health assertions.
