Nutrients in Pregnancy: What You Really Need

Key Nutrients in Detail

Folic Acid. Folic acid is the most important nutrient during pregnancy. Adequate intake has been shown to reduce the risk of neural tube defects in the baby (De-Regil et al., 2015). A daily supplement of 400 µg is recommended, ideally starting four weeks before pregnancy and continuing at least until the end of the first trimester, supplemented by folate-rich foods such as green leafy vegetables and legumes.

Iodine. Iodine is crucial for the thyroid gland of both mother and child, and thus for fetal brain development. As iodine intake in Germany is often borderline, professional societies recommend an iodine supplement, combined with iodized table salt and regular consumption of saltwater fish. In case of a thyroid condition, the dosage should be coordinated with a doctor.

DHA and Omega-3. The long-chain omega-3 fatty acid DHA supports the development of the baby's brain and eyes. A minimum of 200 mg DHA per day is recommended. Those who eat fatty saltwater fish once or twice a week usually meet this requirement through diet; otherwise, a DHA supplement is advisable (Middleton et al., 2018).

Iron. Iron requirements increase during pregnancy, but a general intake is not recommended. Iron should only be supplemented if a deficiency has been identified through blood tests, such as ferritin levels, as unnecessary intake can also have side effects.

Vitamin D and B12. Vitamin D is particularly relevant in winter or with little sunlight and can be well assessed through a blood test. Vitamin B12 is especially important for women who follow a vegetarian or vegan diet, as it is found almost exclusively in animal products.

What you should avoid during pregnancy

Omitting things is just as important as supplementing them. A few things can harm the baby and are easy to avoid.

• High doses of vitamin A: Very high levels of retinol, for example from liver or high-dose supplements, can be harmful during pregnancy. Opt for a pure pregnancy supplement with an appropriate dosage.
• Alcohol and smoking: There is no safe amount here. It's best to avoid them completely from the start.
• Raw animal products: Raw or undercooked meat, raw fish, and raw milk cheese can transmit pathogens such as Listeria or Toxoplasmosis and should be avoided.
• Too much caffeine: Coffee is not forbidden, but the amount should remain moderate, usually up to about two to three cups per day.

Nutrition as a base, supplements as a complement

As important as individual nutrients are, the foundation remains a colorful, balanced diet with plenty of vegetables, whole grains, good protein sources, and healthy fats. Supplements specifically fill the gaps that are difficult to close through food alone, but they do not replace nutrition.

Conclusion

Nutrients during pregnancy do not have to be a source of stress. The most important supplements are folic acid and iodine, sufficient DHA from seafood or a supplement, and iron only in cases of proven deficiency. The rest comes from a balanced diet. Combined with consciously avoiding alcohol, high doses of vitamin A, and raw animal products, you already have the most important levers in hand. It is best to discuss the exact selection and dosage with your gynecologist.
