Is algae-based DHA as good as fish oil during pregnancy and postpartum?

Algae-based DHA is not a lesser substitute for fish oil, it is the original source. Fish accumulate their DHA by eating algae, so an algal-oil supplement is drawing from the same source further up the food chain, without the mercury and ocean-contaminant concerns that come with fish-derived oils.† Research comparing algae-sourced DHA to fish-oil-sourced DHA has found comparable increases in blood DHA levels, meaning the body absorbs and uses the two forms similarly.

Always consult your healthcare provider before starting any new supplement, especially during pregnancy, breastfeeding, or while managing a medical condition.

Where DHA actually comes from

According to the NIH Office of Dietary Supplements health professional fact sheet on omega-3 fatty acids, DHA and EPA are present in fish, fish oils, and krill oils, but they are originally synthesized by microalgae at the base of the marine food chain, not by the fish themselves. Fish are simply a vehicle that has already concentrated DHA from algae through the food chain.

Does the body use algal DHA the same way?

A systematic review of vegetarian sources of long-chain omega-3 fatty acids found that, unlike plant oils such as flaxseed which convert to DHA only marginally, microalgae oil intervention studies showed significant increases in blood DHA levels, comparable to what would be expected from marine sources. A separate comparative study on algal-oil and fish-oil supplements found the two sources to be viable alternatives to one another in terms of DHA delivery.

According to NCCIH, algal oils are a vegetarian source of DHA, and some formulations also contain EPA, making them a genuine alternative rather than a compromise.

Why this matters specifically during pregnancy and postpartum

DHA supports healthy fetal brain development during pregnancy and, during breastfeeding, supports healthy brain development in baby through breast milk.† Algae-sourced DHA avoids the mercury and heavy-metal exposure concerns associated with some fish-derived oils, which matters during a life stage when minimizing unnecessary exposures is already a priority. Total Postnatal + DHA is formulated with vegan, algae-sourced DHA for this reason, supporting postpartum recovery and replenishment as part of a complete formula.†

Our postnatal multivitamin with DHA and methylated folate is one part of the picture, and if you're earlier in pregnancy, Total Prenatal, designed for preconception through breastfeeding, also uses algae-sourced omega-3 support so the nutrient form stays consistent from pregnancy through the fourth trimester.†

• Algal-oil DHA is the original, plant-based source that fish themselves rely on
• Comparative research finds algal DHA and fish-oil DHA raise blood DHA levels similarly
• Algae-sourced DHA sidesteps mercury and ocean-contaminant concerns tied to some fish oils
• It's a genuinely vegan-friendly option, not a downgrade from fish oil

"I wanted a DHA source I could feel good about giving to my own body during pregnancy and while nursing. Choosing algae over fish was never a compromise for me. It was simply going back to where the nutrient actually comes from."

— Amy Suzanne Upchurch, Founder and CEO of Pink Stork

Total Postnatal + DHA is Amazon's best-selling postnatal multivitamin (2024), third-party tested, a Clean Label Project Purity Award winner, and manufactured in cGMP-certified facilities.
