Answers to your questions
Why can’t I just eat fish for DHA?
Some fish do contain DHA, but pregnancy guidelines warn against eating too much due to mercury and other toxins. Even “safe fish” can feel like a gamble when your baby’s brain is developing. PureMama DHA™ gives you the same essential DHA — without any of the risks.
Don’t my prenatals already have DHA?
Many prenatals skip DHA entirely. Others include very small amounts (often 100–150mg), while research shows moms need closer to 300–600mg daily. PureMama DHA™ delivers a higher, clinically relevant dose — in just one capsule.
Why algae instead of fish oil?
Fish get their Omega-3s by eating algae. We skip the fish and go straight to the original source. That means:
No mercury or ocean pollutants
No fishy burps or reflux
Sustainable and vegan
Is algae DHA proven to work as well as fish oil?
Yes. Multiple clinical studies confirm that algae DHA raises blood DHA levels just as effectively as fish oil. OB/GYNs worldwide now recommend algae-based DHA as the safest form for pregnancy.
Will it upset my stomach or cause fishy burps?
No. Unlike fish oil, Keaps DHA™ is odorless, tasteless, and gentle. Moms consistently report no nausea, no burps, and no reflux — even with morning sickness.
How do I know it’s safe for pregnancy?
Every batch of Keaps DHA™ is third-party lab tested for purity, potency, and heavy metals. It’s mercury-free, toxin-free, allergen-free, and carrageenan-free. Safe for pregnancy, breastfeeding, and beyond.
Can I take it while breastfeeding?
Yes. DHA continues to be critical for infant brain and eye development through breastfeeding. Taking PureMama DHA™ helps enrich your breast milk with DHA for your baby.
