Iron deficiency can be common during pregnancy, and experiencing it can increase your baby's risk of low birth weight and prematurity. Iron needs tend to increase to 27 milligrams per day once a pregnant person enters the second trimester. And for some, even more than 27 milligrams per day is needed to meet their growing needs.

Thorne Prenatal contains a whopping 45 milligrams of iron per serving, along with an impressive lineup of other important nutrients. If your healthcare provider expressed any concerns about being at risk for developing iron deficiency, this option may be worth exploring with your doctor, midwife, or dietitian.
