If you’ve discovered you have a deficiency in vitamin D, you’re not alone. It’s particularly common among people who get limited sun exposure, as well as people with dark skin, people over age 65, and people who smoke. Breastfed infants and children with certain medical conditions are also susceptible to vitamin D deficiency.

If a healthcare professional has recommended a vitamin D supplement for calcium absorption, bone health, or muscle growth and development, we’ve vetted and narrowed down our recommendations to 6 supplements when vitamin D in response to sun exposure is not enough or inaccessible.

What is vitamin D?

Vitamin D is an essential nutrient that plays a key role in many aspects of health, including:

  • calcium absorption
  • bone health
  • immune function
  • disease prevention

Because vitamin D is found naturally in very few food sources and is mostly obtained through sun exposure, many people have an increased risk of deficiency.

Vitamin D supplements can help ensure that you’re getting the amount of vitamin D you need. They come in two forms: vitamin D2 and vitamin D3. While both forms can increase blood levels of vitamin D, vitamin D3 can raise vitamin D levels higher and for longer than vitamin D2.

How to choose

Before you decide on a vitamin D supplement, it’s a good idea to get your nutrient levels checked. A blood test is the only way to find out whether you are deficient, insufficient, sufficient, or optimal in any nutrient.

A healthcare professional can order blood work and help you determine an appropriate dosage if a supplement is necessary for you. At-home testing kits may also be useful to measure your vitamin D levels.

Frequently asked questions

Research shows that vitamin D3 is more effective than vitamin D2 at increasing blood levels of vitamin D. A 2020 study also found that both liquid and capsule vitamin D3 supplements can raise vitamin D levels efficiently.

Vitamin D3 is typically better absorbed and used by the body than vitamin D2. Keep in mind, vitamin D is a fat-soluble vitamin, so it requires dietary fat in order to be full absorbed. It’s a good idea to take your vitamin D with a meal containing healthy fats.

The most useful vitamin D will contain D3 and meet your individual needs for dosing and other preferences, like cost and dietary restrictions, and form, like capsule, liquid, or chewable.

The best strength of vitamin D can vary based on individual needs and levels, and it’s possible to overdo it. Be sure to consult with a healthcare professional for personalized dosage recommendations.

The bottom line

The products above are among the best vitamin D supplements on the market and suit a wide variety of needs. Just keep in mind that for optimal absorption, it’s best to take vitamin D supplements with a meal containing fat, such as olive oil or peanut butter.

Before taking any new supplements, it’s important to speak with a healthcare professional to determine whether — and how much — you need to supplement.
