1. Folic acid:

• Why: Folic acid is important for both fertility and early fetal development.
• Recommended amount: Take 400 micrograms of folic acid from the moment you want to become pregnant and continue doing so for the first 10 weeks of your pregnancy.
• Folic acid reduces the chance of spina bifida in your baby and possibly also the chance of a cleft lip, jaw and/or palate (cleft lip). The amount of folic acid that you get through food is usually not enough.

2. Vitamin D:

• Why: Supports bone health and immune system function.
• Recommended amount: 15-20 mg per day, sometimes a higher dose may be necessary based on the vitamin D level in the blood.
• You can also start taking vitamin D from the moment you want to become pregnant. You can use it throughout your pregnancy. Vitamin D is important for the proper bone development of the unborn baby. In addition, there are indications that vitamin D supplementation reduces the risk of gestational diabetes and a child with a low birth weight. It may also reduce the risk of a child developing asthma-like symptoms later in life.

3. Iron

• Why: Prevents anemia and supports the development of the placenta and fetus.
• Recommended amount: 27 mg per day.
• Iron is also very important for your fertility, so make sure you regularly eat iron-rich foods, such as (organic) meat, dried fruits and green leafy vegetables.

4. Omega-3 Fatty Acids

• Why: Supports the development of the baby's brain and eyes and can extend the duration of pregnancy.
• Recommended amount: 200-300 mg DHA per day.

5. Iodine

• Why: Essential for the production of thyroid hormones, which are crucial for the baby's development.
• Recommended amount: 150 mg per day.
