🧪 Formulation Notes

Optimal Prenatal is a comprehensive prenatal formula designed to meet the high nutritional needs of women who are pregnant or preparing for pregnancy – or anyone looking for a well-rounded multivitamin. This formula contains both folinic acid and L-5-MTHF, the most biologically available forms of folate, which are essential during pregnancy to support healthy brain development. L-5-MTHF works in conjunction with amino acids, chelated minerals, and coenzyme forms of B vitamins to support cardiovascular, neurologic, and immune health and normal cell growth. This formula is iron-free to allow for maximal versatility.

Does Not Contain: Milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy protein, GMO, gluten, artificial colors, or artificial flavors.
