Docosahexaenoic acid, or DHA, is an omega-3 fat your body needs for brain, eye, and nerve function. It supports cognitive sharpness and can help maintain memory and focus across the lifespan. Pregnant women often use it to aid fetal brain growth.
DHA usually comes as a softgel or liquid oil. Taking it alongside a meal that contains fat improves how well you absorb it. A fishy aftertaste or mild stomach upset can happen, though these effects are typically minor.
