Vitamin D is a big topic right now.

And considering an alarming 41% of American adults meet the criteria for insufficiency (meaning they have levels lower than 30 ng/ml) and approximately 92% of men and more than 97% of women aren't even getting 400 IU of this essential fat-soluble vitamin from their daily diet, it's well-deserving of the attention.

Given how tricky it is to get ample amounts of the nutrient from food and sunlight alone, taking a supplement is ultimately the route to achieving and sustaining an ideal vitamin D level—which is 50 ng/ml or higher—for life.*

The thing is, though, that all vitamin D supplements are not created equal. In fact, they're far from it.

Here are our top picks for getting the high-quality vitamin D you need (and in ample amounts) from your supplement routine.

The benefits of a vitamin D supplement

Vitamin D is crucial for whole-body health, interacting with the musculoskeletal, immune, neurological, thyroid, gastrointestinal, renal, endocrine, and cardiovascular systems, among others.*

A few of vitamin D's noteworthy roles, in particular, that are worth calling out:

  1. It helps regulate the production of thyroid hormones.*
  2. During pregnancy, it promotes better maternal and infant outcomes related to bone density, immune function, fetal growth, maternal metabolic health, and more.*
  3. It supports immunity, promoting white blood cell function, helping the immune system adapt to and ward off threats, and more.*
  4. It does your gut good by playing a key role in the health and integrity of the gut mucosal lining.*
  5. It helps the body absorb and maintain the proper balance of calcium and phosphorus, which are both crucial for bone health.*

How we chose

At mindbodygreen, our expert-vetted dietary supplement product selections and recommendations in the supplement space elevate quality, efficacy, innovation, and safety.

Our team ensures that each supplement product is thoughtfully formulated--from the active ingredients to those "Other ingredient" excipients too.

Overall, we recommend products with clean ingredients at efficacious doses in bioactive forms. Whenever possible, we celebrate and elevate plant-origin (i.e., plant-sourced) ingredients from a variety of botanicals.

Ingredient source and innovation are top of mind for our critical reviews and selection of supplement products. We prioritize forward-thinking formulations and delivery formats that are genuinely helpful in transforming your health.

What to look for in a vitamin D supplement

We've hand-selected the products featured here and recommend them wholeheartedly.

That said, we also want to give you the know-how to look for your own vitamin D supplements.

Here are a few must-have criteria when searching for a vitamin D supplement, according to mbg vice president of scientific affairs Ashley Jordan Ferira, Ph.D., RDN:

  • Opt for vitamin D3 form (cholecalciferol), which is two to three times more potent than D2 (ergocalciferol).
  • For animal-source D3, look for lanolin (derived from sheep's wool), which is high quality and affordable.
  • For vegetarian or vegan D3 sources, look for algae or lichen (though algae is considered to be more sustainable, and organic algae is the most premium option).

How much vitamin D do you need?

Adults should look for a minimum of 2,000 I.U. per day (5,000 I.U. daily is best, but even more might be necessary if the person has higher body fat or if an individual's D deficiency is stubborn)*


Infants need 400 I.U. of vitamin D per day, while 1,000 I.U. daily is a healthy vitamin D dose for children and adolescents.

The takeaway

Supplementing with vitamin D is a simple (and typically necessary) way to ensure you get the daily vitamin D you need to hit and maintain healthy vitamin D status for life.*

Consult with your health care provider to identify your unique needs and goals, but know that these hand-selected supplements are a great place to start.

If you are pregnant, breastfeeding, or taking medications, consult with your doctor before starting a supplement routine. It is always optimal to consult with a health care provider when considering what supplements are right for you.
