For pregnancy & breastfeeding

Omega-3 DHA for the most important nine months.

DHA is the omega-3 your baby uses most during pregnancy — and a mother’s level varies widely. Know yours with a simple at-home test.

Why omega-3 DHA matters in pregnancy

DHA (docosahexaenoic acid) is a long-chain omega-3 concentrated in the developing brain, eyes and nervous system. It is laid down rapidly through pregnancy, and a mother’s own DHA status is the supply line. Yet levels differ enormously between women, depending on diet, supplements and individual metabolism — and most people have never measured theirs.

The evidence, in brief

Omega-3 in pregnancy is one of the most-studied areas in maternal nutrition. A large Cochrane systematic review of randomised trials examined omega-3 supplementation during pregnancy and its relationship with timing of birth; the wider research base continues to inform guidance. The consistent theme across the literature is that a woman’s baseline omega-3 status is what matters — which is exactly why measuring it, rather than guessing, is useful.

Know your status, then decide. The point of testing is to replace guesswork with your actual number, so any decision about diet or supplements — made together with your midwife or GP — is based on where you really stand.
