Why We Chose This

# Why We Chose This Pregnancy and the months leading up to it demand nutritional support that goes beyond standard multivitamins—your body needs specific micronutrients like iodine, folate, and iron at precise levels to support both your health and fetal development. Thorne's Prenatal Support Stack delivers pharmaceutical-grade formulations designed specifically for women trying to conceive, pregnant, or lactating, so you can focus on feeling strong through this transformative phase.

Thorne's Prenatal Support Stack is a daily multi-vitamin and mineral supplement formulated to help fill nutritional gaps for women trying to conceive, during pregnancy, and while lactating. It features active folate (5-MTHF) and 150 mcg of iodine per serving to support the body's needs at every stage of this journey.

Nutritional health and diet play a key role in a woman’s fertility. Nutritional supplements can help cover gaps in the diet and ensure the body receives the vitamins and minerals that are crucial to promoting fertility.*

Thorne’s Basic Prenatal is a daily multi-vitamin/mineral supplement for women. It’s designed to be gentle and effective for women trying to conceive or who are pregnant or lactating.* Among the various nutrients essential for a healthy pregnancy, the importance of iodine has recently been recognized. Iodine is believed to support a healthy fetus and infant development,* and new recommendations from the American Thyroid Association and the Council for Responsible Nutrition have recommended that women take a prenatal multi-vitamin/mineral supplement that provides 150 mcg of iodine daily (the amount in a daily serving of Basic Prenatal), in addition to eating iodine-rich foods. Sufficient iodine is also essential for healthy thyroid function, which is important for optimal fertility.* A sluggish thyroid can be one cause of fertility problems.

Basic Prenatal contains the active form of folate (5-MTHF). Folate intake is especially important when trying to conceive and during early pregnancy, since its biggest need is during the first trimester – when a woman might not even know she is pregnant.

Prenatal DHA provides support for mom and baby during pregnancy and through nursing with omega-3's. Two essential omega-3 fatty acids - DHA and EPA - to support a healthy pregnancy and development of baby's brain and nervous system.

5-MTHF 1 mg is an active, tissue-ready form of folate.* Folic acid intake is especially important in fertility health, because three out of five U.S. adults have a genetic makeup that makes it difficult to convert folic acid into active 5-MTHF.* Studies have shown that the inability or difficulty to convert folic acid can adversely affect both fertility and pregnancy outcome.

In one recent clinical study, 30 couples who had a history of fertility problems for at least four years (at least one of the partners had the genetic mutation that affects folate metabolism) were asked to take 800 mcg daily of a 5-MTHF supplement for four months prior to trying to conceive. The study found that of the 30 couples, only three failed to conceive.*

Suggested Use:

Basic Prenatal: Take 3 capsules daily. Prenatal DHA: Take 2 gelcaps daily. 5-MTHF 1 mg: Take 1 capsule twice daily.
