Overview
DHA is one of the most critical nutrients for brain health, forming a major part of neuronal membranes. It plays a vital role in cognitive development, maintenance, and ageing. Supplementation is particularly beneficial in individuals with low dietary intake of omega-3s. Its effects are foundational and long-term, rather than immediately noticeable.
