input: [Nutrient] DHA [Notes] 
output: DHA, a potent omega-3 fatty acid, is being studied extensively for health benefits during pregnancy, breastfeeding, and for adult cardiovascular health. DHA is found in good supply in large cold-water fish, and to a lesser extent in eggs and algae (unless concentrated). DHA is not considered an essential fatty acid at this time. Alpha-Linolenic acid (ALA) is an essential dietary fatty acid needed in very small quantities in the human diet. Unfortunately, very little ALA is actually converted to DHA. Vegetarians might want to consider microalgae DHA supplements (with vegan capsules) rather than relying on nut and seed sources of ALA if they are hoping to increase their DHA blood levels. These supplements are common at local vitamin shops or online.
