High Zinc Regimen While Pregnant

Deborah A. Klein's picture


Dear Livitician,
I have a zinc deficiency that causes painful canker sores in my mouth. I have been on a physician prescribed high zinc regimen for about 2 years.

Now that I am pregnant is it sill ok to take a high level of zinc. Is there any point at which it would be considered "too much"?


Hi. You may definitely continue to take zinc, but overconsumption is dangerous and can lead to premature labor or stillbirth.

Take maximum: 20 mg of zinc, including the quantity of zinc that you are taking from your prenatal supplement. So if your prenatal has 15 mg for example, please do not take more than the additional 5 mg. Zinc can interfere with the absorption of Calcium, so take your Calcium supplement separate. Take your zinc and prenatal supplements with food to decrease gastric irritation.

Focus on eating foods with zinc to get the extra zinc that you need, for example, rich sources of zinc, include: egg yolks, fish, milk, molasses (black-strap), sesame seeds, sunflower seeds, turkey, wheat bran, wheat germ, and whole-grain products.

Have a healthy pregnancy!!

Enjoy Liviting!
