With the increase in health awareness, DHA supplementation for pregnant women has become a hot topic recently. DHA (docosahexaenoic acid) is a key nutrient for fetal brain and vision development, but how to scientifically supplement it is still confusing to many expectant mothers. This article combines hot discussions across the Internet in the past 10 days to provide you with structured data and practical suggestions.
1. The importance of DHA to pregnant women and fetuses
DHA is a type of Omega-3 fatty acid, accounting for more than 50% of the cerebral cortex and retina. Lack of DHA during pregnancy may affect fetal neurodevelopment and even increase the risk of premature birth. Social platform data in the past 10 days shows that about 68% of pregnant mothers are concerned about DHA supplementation (see table below).

| Food supplements vs supplements | 35% |
| brand safety | 23% |
2. Three major ways for pregnant women to supplement DHA
1. Dietary sources
Deep-sea fish are the best natural source of DHA, but be aware of the risk of mercury contamination. Popular recommended ingredients are as follows:
| food | DHA content (per 100g) | Recommended amount per week |
|---|---|---|
| salmon | 1.1-1.9g | 2-3 times |
| Sardines | 0.98g | 1-2 times |
| algae | 0.3-0.5g | Can be consumed daily |
2. Nutritional supplements
According to the Chinese Maternal Guidelines, it is recommended to supplement 200-300mg DHA daily. Popular brands are discussed as follows:
| brand | Type | Single grain content |
|---|---|---|
| newmans | algae oil | 200mg |
| Bio Island | fish oil | 250mg |
| Wyeth | multivitamins | 150mg |
3. Fortified foods
Some milk, eggs, etc. add DHA, but you need to check the label to confirm the content. A recent platform review showed that the actual content of DHA-fortified foods can vary by up to 30%.
3. Controversial hot spots and expert advice
Controversy 1: Fish oil vs algae oil
In the discussion in the past 10 days, 53% of users preferred algae oil (no heavy metal risk), but the price of fish oil is lower. Expert advice: People who are allergic to seafood should first choose algae oil.
Controversy 2: Supplementary Time
The peak period of fetal brain development is after 20 weeks of pregnancy, but the latest research suggests that supplementation can begin during pregnancy preparation. A survey at a tertiary hospital showed that pregnant women who started taking supplements in early pregnancy had a 27% lower risk of postpartum depression.
4. Precautions
1. Avoid taking it with vitamin E, as it may affect absorption.
2. The absorption rate increases by 40% when taken after meals.
3. Look for the "TGA" or "FDA" certification mark when purchasing
Conclusion
Based on the data from the entire network, DHA supplementation for pregnant women requires individualized planning. It is recommended that pregnant mothers combine dietary assessment and choose an appropriate plan under the guidance of a doctor to lay a solid foundation for the health of the baby.
