DHA (
docosahexaenoic acid) is an
omega-3 fatty acid. Most comes from marine sources (mainly fatty fish and certain algae and plankton). Because many people do not eat much fish (and since
omega-3 fatty acids are recommended as part of a heart-healthy diet), DHA supplements have become popular in recent years.
Supplementation may be useful for people with
high cholesterol,
heart disease, and numerous other conditions. It may also be beneficial for pregnant and breastfeeding women and in infant formula.

DHA is an essential fatty acid, which means that humans must obtain it from the diet.
This product is thought to work in a variety of different ways, such as:
- Inflammation -- DHA seems to decrease inflammation in the body by suppressing a specific enzyme (COX-2) and inflammatory chemicals, such as interleukin-1 (IL-1) and tumor necrosis factor (TNF).
- Triglycerides -- DHA lowers triglyceride levels by several different mechanisms.
- Blood clotting -- DHA decreases blood viscosity (in common terms, it "thins" the blood) and has effects on red blood cells that may decrease the risk of blood clots.
- Fetal and infant development -- DHA is important for the development of the brain and neurons.
These are just a few of the ways that researchers think this product may work for a variety of conditions. As more studies are done, more information will become available.
