DHA is a long-chain omega-3 fat that forms the structural basis of the brain, eyes, and nervous system. You can get it from fish oil, algae oil, or krill oil supplements.
This fat promotes sharp thinking, healthy eyes, and a balanced inflammatory response. Many people take it to protect memory as they age. It is also a critical nutrient during pregnancy and breastfeeding for the baby's brain development.
Take DHA with a meal that contains fat to boost absorption. Algal oil absorbs well even without added fat. Fish oil supplements typically combine DHA with EPA. You can also buy concentrated DHA alone for targeted brain or eye support.
DHA can thin the blood slightly. If you take blood-thinning medication or have a bleeding disorder, speak with your doctor before using it.
