Pregnancy makes the thyroid work harder. After delivery, immune and hormone changes can place even more stress on it. This can lead to tiredness, poor memory, trouble losing weight and depression. These symptoms can look like postpartum depression, so thyroid testing should include more than a quick look at TSH.
Several nutrients may help support the thyroid:
- Myo-inositol helps the thyroid respond to TSH. It may also improve insulin resistance, which can interfere with thyroid function.
- Selenium helps change T4 into the more active thyroid hormone, T3. It may also help lower thyroid antibodies. Too much selenium can be harmful, so count what is already in the prenatal vitamin.
- Iodine is needed to make thyroid hormone. Pregnant and breastfeeding women need more, but very high doses can make thyroid problems worse.
- Magnesium supports blood sugar control and helps the body handle stress. Both stress and insulin resistance can interfere with thyroid function.
- B vitamins support energy production, stress response and many of the chemical reactions needed for healthy thyroid function.
- Phosphatidylcholine supports the liver, which helps process thyroid hormones and remove fat. Pregnancy and breastfeeding also increase the body’s need for choline.
These nutrients do not replace thyroid medication when it is truly needed. However, they may help support a borderline thyroid before it becomes a much larger problem.
