Is DHA a fatty acid?

In fact, DHA comprises over 90% of the omega-3 fatty acids in your brain and up to 25% of its total fat content ( 3, 5 ). While it can be synthesized from alpha-linolenic acid (ALA), another plant-based omega-3 fatty acid, this process is very inefficient. Only 0.1–0.5% of ALA is converted into DHA in your body ( 6, 7, 8, 9, 10 ).

What is DHA & how does it work?

DHA is naturally produced in small quantities by our bodies, but to achieve adequate amounts, DHA needs to be taken in through dietary sources such as cold-water fish, grass-fed meat, dairy products, or omega-3 enriched or pasture-raised eggs. It is also available as a supplement, such as fish oil.

What does DHA stand for?

?) Docosahexaenoic acid ( DHA) is an omega-3 fatty acid that is a primary structural component of the human brain, cerebral cortex, skin, and retina. It is given the fatty acid notation 22:6 (n-3). It can be synthesized from alpha-linolenic acid or obtained directly from maternal milk (breast milk), fatty fish, fish oil, or algae oil.

What is docosahexaenoic acid (DHA)?

Docosahexaenoic acid (DHA) is an omega-3 fatty acid essential for brain development during pregnancy and early childhood. It is also linked to improved heart health, better vision, and reduced inflammatory response. This long-chain fatty acid is found in cell membranes throughout the body and helps to transmit messages between nerves.

What is EPA & DHA?

Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) are LCN-3 fats. ALA makes these in your body. This happens slowly and only small amounts are formed. EPA and DHA are important for your heart, blood vessels, lungs and the immune and hormone systems. DHA is also important for the development of the retina (eyes) and brain in infants.

What is DHA & why is it important?

DHA is the main omega-3 fat in your brain and essential for a functional nervous system, which includes your brain. Studies have shown that people with Alzheimer’s disease have lower levels of DHA in their brains than older adults with good brain function ( 39 ).
