How Docosahexaenoic Acid works

Docosahexaenoic Acid (DHA) is an essential omega-3 fatty acid that becomes part of cell membranes, particularly in the brain and eyes.

It helps maintain the flexibility and function of these cell membranes, supporting healthy signalling between cells.

DHA also helps reduce the production of inflammatory substances in the body and supports healthy blood vessel function, which together contribute to its benefits for heart, brain, and eye health.
