When you’re pregnant—or trying to conceive—every decision feels high-stakes.
What you eat, what you breathe, and especially what supplements you take can impact your baby’s development.
But here’s what most women don’t realize:
Not all vitamins marketed for pregnancy are safe.
Some may even do more harm than good.
At Ask Dr Olz, we believe in empowering women with accurate, functional medicine-based guidance—especially during this sacred season of life.
Let’s talk about which pregnancy vitamins to avoid, and why we recommend MamaPlus® as a trusted, practitioner-approved option.
Here are the most common problematic ingredients and practices found in over-the-counter pregnancy supplements:
High doses of preformed vitamin A (retinol) have been associated with birth defects. While beta-carotene is safe, synthetic or high-dose retinol should be avoided.
Some “natural” supplements contain herbs like black cohosh, dong quai, or yohimbe—all of which can interfere with pregnancy hormones or uterine contractions.
Many prenatal supplements use folic acid instead of methylated folate, which is better absorbed and safer for women with MTHFR gene variations.
Too much iron—or iron from poorly absorbed forms—can cause oxidative stress or GI distress during pregnancy.
Just because it’s sold in a pharmacy doesn’t mean it’s safe. The supplement industry is loosely regulated, and many formulas lack the clinical research needed to ensure safety during pregnancy and nursing.
If you’re looking for a comprehensive, nutrient-dense supplement that supports you before, during, and after pregnancy, MamaPlus® is a gentle and effective option.
