DHA (Docosahexaenoic Acid)
DHA is a long-chain omega-3 fatty acid concentrated in brain gray matter, retina, and sperm membranes. It supports neural development and visual function and is particularly important during pregnancy, infancy, and aging. Higher DHA intake is linked with better cognitive performance and possibly slower cognitive decline. Oily fish and algae are the main sources.
Optimal range: who says what
Institutions, researchers and practitioners draw the line in different places. Each position is listed with who holds it and, where a document states it, a link. How we verify ranges.
- Institution or studyOmega-3 Index (EPA+DHA) of 8% or higherOmega-3 Index research (Harris et al.)DHA alone has no consensus target; it is tracked as part of the index
- Lab reference intervalNo established reference range; higher levels generally betterWhat a lab report flags against. A lab interval is not an optimal target.
