When I was looking for my daily prenatal vitamins + supplements, I started with a master list of “ingredients” that I wanted to ensure I was meeting for me + baby.
Here’s a master list of the most common vitamins and minerals in prenatal vitamins and an overview of what they do in the body.
Use this list as a benchmark for choosing your prenatal:

- Vitamin A: Supports eye and brain development, respiratory development
- Thiamin (Vitamin B1): Supports the nervous system, supports baby’s brain development
- Riboflavin (Vitamin B2): Supports healthy eyes and skin
- Niacin (Vitamin B3): Supports the digestive, integumentary, and nervous systems
- Pantothenic (Vitamin B5): Helps to create hormones and may ease leg cramps
- Vitamin B6: Helps form red blood cells and may help with morning sickness
- Biotin (Vitamin B7): Works with other B vitamins to help release energy from food
- Folate/ Folic Acid (Vitamin B9): Prevents neural tube defects and Spina Bifida in baby. Be aware that if you have the MTHFR genetic mutation, you’re going to want to discuss what specific version of this you need with your practitioner.
