Seven Seas
Pregnancy Vitamins with Omega-3 DHA
7.3/10 overall£9.99 (28 capsules + 28 tablets)
A capsule-and-tablet duo pack combining Omega-3 DHA for brain and vision development with advanced folic acid.
The structural idea here is sensible: split the omega-3 DHA into its own capsule and keep the folic acid and standard nutrients in a separate tablet, so each part can be dosed properly rather than compromising on omega-3 levels to fit everything into one pill. DHA specifically supports the baby's brain and vision development, and a fair few standard all-in-one prenatals either skip it or include a token amount — Seven Seas does not skimp on it, which is the main reason to pick this over a simpler single-tablet option.
Against Pregnacare Original, the price comparison favours Seven Seas noticeably — it is meaningfully cheaper while still covering folic acid and the core pregnancy nutrients, plus the dedicated omega-3 dose Pregnacare lacks. What you give up is simplicity: this is two pills, twice a day (one capsule, one tablet, morning and evening, or as directed), rather than Pregnacare's single daily tablet. For anyone who struggles to remember multiple doses, or who wants pregnancy vitamins to be a one-and-done morning habit, that is a real point against it.
This is a good fit for anyone specifically prioritising omega-3 intake — whether because they do not eat oily fish regularly, have read up on DHA's role in fetal brain development, or simply want the more complete nutrient coverage without paying branded-multivitamin prices. If you would rather take one tablet and be done with it, or omega-3 is not a priority for you, Pregnacare Original's simplicity is the better fit.
The honest downsides: remembering two separate products across the day is more admin than a single tablet, particularly on the mornings when first-trimester nausea makes swallowing anything feel like an effort. A handful of people also report a mild fishy aftertaste from the DHA capsule, which some manage by taking it with food or freezing the capsules briefly before taking them (a common trick with fish-oil supplements) to reduce burping.
