Supplement Facts & Ingredients
Learn More

Mamas need Vitamin D3 and K2 to support optimal fertility, immune function in mama and baby, healthy bone development in baby, an overall healthy and full-term pregnancy, adequate breastmilk Vitamin D levels, postpartum recovery, and more*. Vitamin D3 and K2 are the optimal nutrient forms, and the two work synergistically together*. Some mamas need more Vitamin D3/K2 due to genetics, diet, geography, life stage (including while breastfeeding) or other factors. Our D3/K2 topper is ideal for when you need an extra boost.
How to Use

Take one capsule up to five times daily with food. 2 capsules (4,000IU of D3 and 90mcg of K2 per day)) is a highly effective and safe dose for most mamas during pregnancy. We recommend the equivalent of 3 capsules (6,000IU D3) while breastfeeding to ensure baby receives adequate nutrition. If you are taking Needed's Prenatal Multi, be mindful that we include 4,000IU of D3 and 90mcg of K2 in our base formula. See our dosage chart below for the right dose to meet your unique needs.

Thoughtful inquiry is needed.

What makes Needed’s Prenatal Vitamin D3/K2 different from others?
We use optimal nutrient forms paired at an optimal ratio for the perinatal life stage. Plus, our D3 + K2 comes in smaller capsules for easy taking and dosage tailoring.
Why do you offer Vitamin D3/K2 separately from your Prenatal Multi?
For most mamas in pregnancy, 4,000IU of D3 and 90mcg of K2 per day (2 capsules) is highly effective and safe. Our Prenatal Multi is dosed at this level. Some mamas, due to genetics, diet, geography, life stage (while nursing we recommend at least 6,000IU / 135mcg) or other factors, may need or benefit from a higher dose.
How do I know how much Vitamin D3/K2 I need?
Start by scrolling up and reviewing our dosage chart or by testing your Vitamin D3 levels. This chart and ratio of Vitamin D3/K3 was set in partnership with a group of women’s health practitioners that regularly test women's nutrients levels before, during, and after pregnancy.
Is your Vitamin D3+K2 vegan, allergen free, and Non-GMO?
It is vegetarian and allergen free, meaning no milk, egg, fish, shellfish, tree nuts, peanuts, wheat, soy, and gluten are contained in the product. It is also free of GMOs, artificial colors, artificial flavors, preservatives, and other additives and fillers.
What are the “other ingredients” in your Vitamin D3+K2?
D3+K2 are carried in vegetable capsules made from cellulose with a small amount of extra cellulose and the amino acid, L-Leucine, to help place the nutrients into capsules.
Where is your D3+K2 manufactured?
Our D3+K2 is manufactured in the United States in a GMP Certified facility.
What kind of testing do you do?
We test every batch for performance and quality, including through third parties that test for nutritional content, pesticides and herbicides, heavy metals, microbes, allergens, and other contaminants.
