Docosahexaenoic acid (DHA) is a long-chain omega-3 fatty acid that plays a vital role in brain development, eye health, and cardiovascular function. It is particularly important during pregnancy, infancy, and aging to support cognitive function and overall health.

What Is DHA?

DHA is an essential fatty acid primarily found in marine sources. It is a key structural component of the brain, retina, and cell membranes throughout the body. Since the body produces minimal amounts of DHA, it must be obtained through diet or supplementation.

    • DHA is a fundamental component of brain cells, enhancing memory, learning, and cognitive performance.
  2. Promotes Heart Health:
    • Helps reduce triglyceride levels, lower blood pressure, and improve overall cardiovascular function.
  3. Enhances Eye Health:
    • DHA is essential for retinal development and helps maintain clear vision.
  4. Aids in Pregnancy and Infant Development:
    • Crucial for foetal brain and eye development, benefiting both mother and baby.
