An essential omega-3 fatty acid that keeps your brain sharp, vision clear, and heart healthy.
What it is
Docosahexaenoic acid (DHA) is a vital long-chain omega-3 fatty acid found in microalgae and cold-water fish. In supplements, DHA comes from purified fish oil or algae oil. DHA is a primary structural fat in your brain cells, retina (eyes), and heart tissue. It keeps cell membranes flexible so signals can pass smoothly between cells.
Also known as: DHA Omega-3, Omega-3 DHA
Key benefits
- Supports normal brain function and mental clarity at every stage of life.
- Maintains clear vision and supports healthy photoreceptor cells in your eyes.
- Supports heart wellness by helping maintain healthy blood fat (blood fats (triglycerides)) levels.
Amplified by probiotics
Absorbing healthy fats like DHA requires a well-balanced digestive system. Friendly probiotic bacteria help balance digestive bile and strengthen your gut lining. By keeping the gut barrier strong, probiotics protect sensitive omega-3 fats from oxidation during digestion. Each probiotic bacterium is protected by a micro-shield so it arrives safely in your gut, ensuring optimal absorption of DHA into your bloodstream.
Typical dose
250–1000 mg/day
The evidence
Evidence: strongMany human studies show that taking DHA raises healthy omega-3 levels in cells to support brain and eye health (Horrocks 1999, Pharmacol Res). Controlled human studies confirm consistent benefits for brain development during pregnancy and for adult heart health (Swanson 2012, Adv Nutr).
Safety & who should check first
DHA is extremely safe and well tolerated. It is safe and recommended during pregnancy and breastfeeding. Speak to a doctor before taking very high doses if you take blood-thinning medication or have an upcoming surgery.
