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 years, 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 eight supplements for when vitamin D from sun exposure is not enough or inaccessible.

A note on price

Healthline's review

If you have a severe vitamin D deficiency, a healthcare professional will likely recommend taking a high dose supplement — at least 10,000 international units (IU) daily. This may be followed by a maintenance dose of up to 6,000 IU once your levels normalize.

Pure Encapsulations Vitamin D3 gets our pick as the best high dose vitamin D option because it’s third-party tested and provides 10,000 IU per serving.

Plus, unlike other products on the market, it’s hypoallergenic, non-GMO, and gluten-free, so it’s a great choice for people with food allergies or dietary restrictions.

Keep in mind that this product is not suitable for vegans since it contains vitamin D3 derived from lanolin, a type of fat secreted from sheep’s wool.

However, Pure Encapsulations also offers a lower dose vegan-friendly alternative, which is made with vitamin D3 sourced from algae.

• vegetarian-friendly
• third-party tested
• manufactured in facilities that exceed the standards of U.S. Pharmacopeia (USP)
• gluten-free and non-GMO

• high dose not appropriate for all people

Healthline's review

Thorne Vitamin D/K2 Liquid wins our vote because it’s one of the few vitamin D supplements that also provides vitamin K2, which works together with vitamin D and is necessary for heart and bone health.

This supplement also offers a convenient way to take your dose of vitamin D, especially if you dislike taking capsules or have difficulty swallowing. These drops can be mixed into any food or beverage.

It’s one of the most affordable options on our list and is free of soy, gluten, dairy, and artificial flavors and additives. Plus, it’s vegetarian-friendly, as it contains vitamin D derived from lanolin and vitamin K2 from geraniol, a plant-based compound found in many essential oils.

• provides 167% of the Daily Value (DV) for vitamin K2
• affordable
• certified by the Therapeutic Goods Administration, an Australian regulatory agency
• gluten-free and vegetarian-friendly

• not third-party tested
• not suitable for vegans

• Active ingredients: vitamin D 25 mcg (125% DV), vitamin K 200 mcg (167% DV)
• Returns: free returns on unopened products within 45 days
• Shipping: free shipping on orders over $35

Healthline's review

For people who prefer getting their nutrient supplements in chewable form, NOW’s budget-friendly, sugar-free offering packs 5,000 IU of vitamin D3. This product is easy to find at many retailers and online.

Sweetened with the sugar alcohols sorbitol and xylitol, it also contains natural vanilla and peppermint flavors. Additionally, it’s kosher, soy-free, and gluten-free.

Note that because this product is made with cellulose, the vitamin D it contains is less absorbable than the vitamin D in oil-based capsules.

• only need to take 1 tablet every 2 days
• budget-friendly
• free of added sugars
• third-party certified by UL Solutions

• contains sugar alcohols, which some people may prefer to avoid
• less absorbable than oil-based capsules
• not suitable for vegans

• Active ingredients: vitamin D3 (125 mcg)
• Returns: free returns for Prime members
• Shipping: free shipping for Prime members

Healthline's review

Mindbodygreen’s Vitamin D3 potency+ contains a blend of vitamin D3 and organic medium-chain triglycerides (MCT) from coconut, which can help improve absorption and potentially make it easier to digest. This is because Vitamin D is a fat-soluble vitamin and requires dietary fat in order to be absorbed.

This product is non-GMO, dairy-free, soy-free, and gluten-free.

Mindbodygreen products are third-party tested, but the names of the labs are not disclosed.

Healthline editors Candice Abellon and Kelli McGrane both tested mindbodygreen’s Vitamin D3.

“I’d recommend these vitamin D capsules based on the fact that they were easy to swallow,” Abellon commented. She also noted the high quality packaging and the substantial feel of the brown glass bottle, highlighting its aesthetic and protective qualities.

That being said, she cautioned, “It’s nice that the D3 for this vitamin is derived from a plant or algae, but the capsule has bovine gelatin, so it’s not vegetarian or vegan.”

McGrane appreciates the brand’s commitment to quality and third-party testing, finding the product easy to use daily with its one-a-day formulation.

“With that said,” she added, “the company’s products aren’t cheap, and some ingredients seem like they’re there more for advertising purposes than because there’s substantial research to back up their effectiveness.”

McGrane continued, “While I do like the product, I’m debating continuing with it because I have to purchase it from mindbodygreen’s website.”

Lastly, as a registered dietitian, McGrane also raised a concern about the high dosage of this product, advising that it is best suited for those specifically directed by a healthcare professional to take 5,000 IUs of vitamin D.

• third-party tested
• gentle on digestion
• enhanced absorption due to MCT oil

• expensive
• not suitable for vegans because of gelatin capsule

• Active ingredients: organic algel vitamin D3

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, getting your nutrient levels checked is wise. 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.
