Product Details

Easy-to-take D3+K2 capsules that are small in size and can be flexibly dosed to meet your unique needs*. Our D3+K2 topper is ideal for when you need an extra boost beyond the highly supportive dosage in our Prenatal Multi, including while breastfeeding.

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. Store fully sealed at room temperature.

    They really know their stuff

    So many vitamin D supplements are only vitamin D, but after learning it is best taken with a source of vitamin K I knew that Needed really knew their stuff and that this was the supplement for me

    Love the combination

    I have been taking a Vitamin D supplement for years, but decided to switch to this one last year because I like that it is combined with K2. These two go great together!

Ready to talk to your health practitioner about our better D3/K2?

Questions? We have answers.

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 mothers 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 mothers, 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+K2 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?

Our Vitamin D3+K2 is vegetarian and non-GMO. Free of 9 major allergens, gluten, and unwanted fillers.
