DHA plays a supporting role in longevity. 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.
What dose to look for
Clinical studies typically use 250–1000 mg of dha. 250mg minimum for vision/brain maintenance; 500-1000mg for cognitive outcomes. Products below this range may not deliver meaningful results.
