The 8 Best Vitamin D Supplements For Immunity, Bone Health & More*

How To Use The Emotion Wheel To Better Understand Your Feelings

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 93% of U.S. adults 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 (OK, more like impossible) 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.

Quick list:

Our Favorite Vitamin D Supplements

A lower potency dose (2,000 IU) and sourced from organic lichens, Truvani's vitamin D3 supplement comes in the form of an uncoated tablet. It's completely vegetarian- and vegan-friendly. Though it's plenty small enough to swallow easily, you can also crush it up or dissolve it into smoothies or other foods. It's also free of corn byproducts, artificial ingredients, and other unnecessary additives, but you will find organic tapioca, rice hulls, and acacia fiber.

bottle of NOW chewable vitamin D3

Best chewable: NOW Chewable Vitamin D3 5,000 IU

$14.99

If you have trouble swallowing supplements, this option from NOW comes in a tasty chewable form with a natural mint flavor. To address most people's high vitamin D needs given lack of sun exposure and limited food sources high in the nutrient, this supplement provides 5,000 IU of D3. (FYI: A little natural color variation may occur; nothing to worry about!) Some folks have GI considerations with sugar alcohols, so we'll mention that those are in this formula, just in case.

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—or, at the very least, help you understand our selection process.

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

  • 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)* Note: 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.
  • 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).

The benefits of vitamin D.

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.*

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.
