How We Designed Our Prenatal Supplements

Our Prenatal formulation is based on the groundbreaking research of Dr. James B. Adams of the Neurological Health Foundation who aggregated insight from 350+ research papers to distill recommendations for the optimal supplementation levels for key vitamins and minerals to reduce pregnancy complications and infant health problems. 

The result is the most comprehensive prenatal supplement program available and we’re so proud to share it with you. 

Here’s what makes our prenatal the gold standard in prenatal supplementation:

Backed by Research

Dr. Adams and his team conducted extensive reviews of hundreds of research studies on how nutritional deficiencies were associated with pregnancy complications and infant health problems, as well as reviews of many clinical trials of the benefits of supplementation. 

Dr. Adams and his team grounded their recommendation against The Recommended Daily Amount (RDA), which establishes a minimum recommended level from all sources, as well as The National Health and Nutrition Examination Survey (NHANES), which establishes average intake from foods. The difference is what needs to be consumed in a supplement, on average, and the Neurological Health Foundation generally recommends more than the difference between the RDA and the NHANES based on the standard American diet and the high Tolerable Upper Limits of most vitamins and minerals.

In some cases, our recommendations will exceed the RDA based on additional research studies and clinical trials which demonstrated an increased need for those nutrients during pregnancy and benefits from higher levels of those vitamins and minerals.

    Customized by Trimester

    The levels of many essential minerals decrease during pregnancy if un-supplemented, while simultaneously your and baby’s nutrient needs change every trimester as their body and brain rapidly developing. We’ve designed our prenatal with custom formulations for each trimester to meet these changing needs. 

    Two Complete Daily Servings

    Our Prenatal is delivered in two cartons: Serving 1 of 2, which we recommend taking with your first meal and 8oz of water and Serving 2 of 2, which we recommend taking with a meal and 8oz of water later in the day.

    But why so many pills? 

    We know it’s not easy to take so many pills, but one pill barely contains enough for the body’s need for calcium, let alone all the other vitamins and minerals.  Prenatals with only 1 pill generally have low amounts of the vitamins and minerals needed in large amounts, such as calcium, magnesium, choline, and DHA. Breaking our recommended daily amounts over two servings not only ensures that you are receiving optimal amounts of key nutrients, but also helps with absorption by spacing intake throughout the day.

    Bioavailable Forms of Vitamins and Minerals

    ‘Bioavailabilty’ refers to the ease with which your body is able to absorb vitamins and minerals. It may come as a surprise to learn that vitamins come in many forms, some forms more bioavailable than others. Supplement makers are generally pressured to cut costs by using cheaper and less bioavailable forms of vitamins and nutrients, thereby limiting their absorption and efficacy in the body. Our Prenatal formulation, however, is made with premium nutrients for your body to absorb with ease and put to good use.

    Below, is a comprehensive look at each and every vitamin and mineral included in our prenatal.

    Vitamin B9 (Folate)

    [As Calcium L-5-Methyltetrahydrofolate]

    Folate supplementation during pregnancy is proven to reduce neural tube disorders and has been shown to reduce the rate of other birth defects, preterm birth, and autism. Folic acid is an artificial form of folate, and people vary greatly in their ability to convert it to the bioavailable forms, so we always use the most bioavailable form - 5-methyl-tetrahydrofolate (5-MTHF).
