DHA

DHA is the primary structural omega-3 in the brain (~97% of brain omega-3s) and retina (~93% of retinal omega-3s). Critical during pregnancy for fetal brain development — minimum 200-300mg DHA recommended. Phospholipid-bound DHA (e.g. krill oil) crosses the blood-brain barrier more efficiently. rTG form preferred over ethyl ester for bioavailability.
