Pregnancy is a time when your body undergoes many changes, and proper nutrition becomes even more critical to support both your health and the healthy development of your baby. Prenatal vitamins are specially formulated supplements designed to ensure that you are getting all the essential nutrients needed during pregnancy. These vitamins and minerals help to fill any gaps in your diet and support your body’s increased nutritional needs during this important time.
Prenatal vitamins are crucial for both the mother and the baby. They provide an extra boost of essential nutrients that may be harder to get from food alone during pregnancy. Some of the most important nutrients include:
-
Folate (Folic Acid): Helps prevent neural tube defects in the baby, which are serious birth defects of the brain and spine.
-
Iron: Supports the increased blood volume during pregnancy and helps prevent anemia.
-
Calcium: Important for the development of your baby's bones and teeth.
-
Vitamin D: Essential for bone health and the immune system.
-
Iodine: Supports thyroid function, which regulates metabolism and overall growth.
When choosing a prenatal vitamin, you should look for a product that contains key nutrients in bioavailable forms that are easy for your body to absorb. Here are the nutrients you should pay close attention to:
-
Folate: Choose a prenatal with L-methylfolate (the active form) instead of folic acid, especially if you have difficulty processing folic acid.
-
Iron: Look for bioavailable iron such as iron bisglycinate, which is gentler on the stomach.
-
Calcium & Magnesium: These help build your baby’s bones and are also important for muscle function.
-
Vitamin D: Important for calcium absorption and bone health.
-
Iodine: Vital for thyroid health and baby’s metabolism.

The recommended time to start prenatal vitamins is at least 3 months before trying to conceive. The most critical nutrient during early pregnancy is folate (or L-methylfolate, the active form), which helps prevent neural tube defects. The neural tube, which eventually forms the brain and spinal cord, develops very early often before many women even realize they're pregnant. Please speak with your healthcare professional to see which prenatal vitamins works for you.
