Which is better for pregnant women, fish oil or algal oil DHA

Pregnant women usually choose algal oil DHA over fish oil DHA, as algal oil DHA has advantages such as pure plant-based sources, no risk of heavy metal pollution, and is more suitable for vegetarians. Fish oil DHA may contain EPA, pose allergy risks, and some products may have a fishy odor. Both can promote fetal brain and nerve development, but the choice should be based on individual needs.

Algae oil DHA is directly extracted from marine microalgae and does not contain EPA from fish sources, which is more in line with the pure demand of pregnant women for DHA. Its production process avoids the problem of heavy metal accumulation in the marine food chain and has higher safety. Algae oil DHA is suitable for pregnant women who are allergic to fish or follow a vegetarian diet, and it is more easily accepted during the morning sickness period without obvious odor. Some algal oil products also contain antioxidant components such as vitamin E, which can improve the stability of DHA. Fish oil DHA usually contains a certain proportion of EPA, although EPA is beneficial for adult cardiovascular health, it may affect the coagulation function of pregnant women. DHA extracted from deep-sea fish poses a risk of heavy metal residue and requires the selection of products that have been purified through molecular distillation. Some pregnant women may be allergic to fish protein, and the unique fishy smell of fish oil may exacerbate pregnancy reactions. However, fish oil DHA has a relatively low price and contains natural forms of vitamins A and D.

It is recommended that pregnant women limit their daily intake of DHA to 200-300 milligrams and prioritize using algae oil DHA products with special labels for pregnant women. Pairing with foods rich in linolenic acid such as walnuts and deep-sea fish can promote DHA conversion and avoid affecting absorption when taken with calcium supplements. When diarrhea or rash occurs, supplementation should be suspended, and the doctor should be informed of the use of DHA during prenatal examination in order to adjust the dosage. Long term use requires choosing a pure formula that does not contain preservatives or artificial colors.
