  • Amount of vitamin D: 50 mcg (2,000 IU)
  • Other ingredients: Food and herb blend consisting of S. cerevisiae, broccoli, brown rice, carrot, parsley leaf, and beetroot

MegaFood is often cited as the best vitamin D brand on the market. However, it’s also a go-to for supplements in general. This popularity in part stems from the company’s focus on transparency. Namely, you can find a list of all MegaFood’s third-party certifications and internal standards on the company’s website. 

As for the supplement itself, it’s one of the best-absorbed vitamin D supplements on the market. It combines vitamin D-3 with extracts from several whole foods, like organic beetroot and broccoli leaf. This combination increases the efficiency of the vitamin. Therefore, this supplement has the potential to improve your immune health and bone strength. 

It’s also important to note that this supplement is a certified non-GMO product tested for more than 125 herbicides and pesticides.

  • Vegetarian and kosher-friendly

2. NatureWise Vitamin D3 Review

OVERALL RATING 9.8
  • Price: From $10.99
  • Form: Softgel capsule
  • Serving size: 1 softgel
  • Servings per container: 90
  • Amount of vitamin D: 125 mcg (5,000 IU)
  • Other ingredients: Organic extra virgin olive oi

Being a best seller in the vitamin supplement category on Amazon, many would call this product the best D3 vitamin on the market. We have to agree as well, but only because we’ve checked everything else about it and realized that it does deserve a spot on our list. 

It’s great that this vitamin supplement uses softgels, as the body more readily absorbs them. It has a trace amount of extra virgin olive oil, which only improves the absorption and makes the pills easier to swallow.

NatureWise’s supplement contains only organic vitamin D3 and extra virgin olive oil and nothing else, making it the best organic vitamin D3 supplement on the market. It’s also entirely non-GMO and gluten-free, which is great news for those leading a gluten-free life

Moreover, it’s important to note that third parties like the NPA and NSF have tested the supplement to verify its quality and potency.

PROS:
  • Very affordable
  • Easy to swallow
  • Top-rated vitamin D product
  • The body absorbs it much faster
  • Completely natural, non-GMO, and gluten-free
CONS:
  • The softgel capsules sometimes stick to each other
  • Complaints that the product doesn't improve mood as advertised

3. Pure Encapsulations Vitamin D3 250 mcg Review

OVERALL RATING 9.7
  • Price: From $25.10
  • Form: Capsule
  • Serving size: 1 capsule
  • Servings per container: 60
  • Amount of vitamin D: 250 mcg (10,000 IU)
  • Other ingredients: None

Pure Encapsulations is not a typical vitamin D3 supplement as it’s predominantly made for people with severe vitamin D deficiency. 

The product contains 10,000 IU of vitamin D, a daily recommended dosage for people with very low levels of this fundamental vitamin. The vitamin is crucial for healthy bone composition and cellular support for prostate and breast tissue.

There are several reasons why we firmly believe this is the best vitamin D3 supplement in 2020 for people in need of high doses. First of all, it has the right dosage that a person with a deficiency needs. 

Second, the product comes from a trusted brand, one that’s certifiably gluten-free and hypoallergenic. The certification comes from the United States Pharmacopeia (USP), an organization known for its strict standards. 

Finally, the supplement contains nothing besides vitamin D3, which is all you need. 

So without a doubt, PureEncapsulations is the best vitamin D3 supplement to take if you’re looking for a completely pure, high-dosage vitamin D3 product.

PROS:
  • Gluten and GMO-free
  • Doesn’t contain any common allergen
  • Perfect for people with a severe deficiency
  • A pure supplement made with premium ingredients
CONS:
  • Some customers complain about an unpleasant smell
  • Not for most people as it has a high dose of vitamin D

4. Now Foods Vitamin D3 5,000 IU Softgels Review

OVERALL RATING 9.6
  • Price: From $12.99
  • Form: Softgel capsule
  • Serving size: 1 softgel
  • Servings per container: 120
  • Amount of vitamin D: 125 mcg (5,000 IU)
  • Other ingredients: Extra virgin olive oil

Now Foods is another one of the best vitamin D3 products for people who need support for their immune system or want to maintain high bone strength. The product’s form, softgels, is a preferred form for many people as it’s typically highly-absorbable compared to other formats. 

The good thing about this product is that Now Foods offers it in two sizes, one with 120 softgels and the other with 240. The latter is only $10 more, so it’s more worthwhile if you plan on using it in the long run. 

You should contact your physician to check if this product is the right one for you, especially if you’re already taking medication or have a specific medical condition like hypercalcemia or kidney disease. If they approve, you’ll quickly see that this is the best vitamin D to take if you’re looking for a potent, pure vitamin D product with a high dosage.

PROS:
  • High potency
  • GMO-free
  • Affordable
  • Positive reviews
CONS:
  • Some users complained about the capsules sticking together

5. Full Circle Prenatal Multivitamin Review

OVERALL RATING 9.4
  • Price: From $49.95
  • Form: Capsules
  • Serving size: 8 capsules
  • Servings per container: 30
  • Amount of vitamin D: 100 mcg (4,000 IU)
  • Other ingredients: Vitamin A, vitamin C, vitamin E, vitamin K, thiamin, niacin, vitamin B-6, folate, biotin, magnesium, calcium, copper, zinc, etc.

If you’re on the lookout for the best vitamin D supplement for pregnancy, then you shouldn’t look further than Full Circle Prenatal Multivitamin. This excellent multivitamin supplement includes all the important vitamins, minerals, and nutrients a pregnant woman needs. 

More importantly, the company behind it made sure not to cut corners when it comes to purity and potency. That’s also one of the main reasons why we think this is one of the best vitamin D supplements on the market. 

As for vitamin D, you should know that it’s generally recommended for pregnant women to take a lot more vitamin D daily than the recommended 600 IU. Most experts agree pregnant ladies should take at least 4,000 IU every day, which is exactly how much this product gets you. 

However, you’ll likely need more after you give birth and during the breastfeeding stage. Even though that’s the case, this is still the best vitamin D supplement and multivitamin for pregnant women.

PROS:
  • Designed by registered dietitian and mother
  • Enough vitamin D for most pregnant women
  • Includes all vitamins, minerals, and nutrients pregnant ladies need
  • Doesn’t cause nausea like some other prenatal supplements
  • Doesn’t contain gluten, tree nuts, wheat, eggs, milk, shellfish, soy, or peanuts
CONS:
  • Relatively expensive
  • Taking eight capsules a day can be too much for some

6. Thorne Vitamin D/K2 Review

OVERALL RATING 9.3
  • Price: From $25.00
  • Form: Liquid
  • Serving size: 2 drops
  • Servings per container: 600
  • Amount of vitamin D: 25 mcg (1,000 IU)
  • Other ingredients: Vitamin K, mixed tocopherols, triglyceride oil

These are arguably the best vitamin D drops you’ll be able to find. Namely, Thorne Vitamin D/K2 is a great and practical vitamin D and vitamin K supplement. As it comes in the form of drops, you can take it easily every day by adding it to your food. 

The Thorne supplement provides a whole host of essential benefits, as it improves bone, joint, heart health, etc. It does more for your immune system, cardiovascular system, and bone health than taking individual vitamin K and D supplements, as these two vitamins work very well together.

Furthermore, this great liquid vitamin D supplement is certified by the Australian Department of Health, making Thorne a trusted supplement brand on the market. 

However, bear in mind that this might not be a good option for you if you’re using a blood-thinning medication, as vitamin K can offset the effects.

PROS:
  • Best liquid vitamin D for daily consumption
  • Derived from natural colors and flavors
  • Soy, dairy, and gluten-free
  • Easy to take, can be added to food
CONS:
  • The dropper mechanism may be too slow for some

7. Vital Choice Sockeye Salmon Oil + D3 Review

OVERALL RATING 9.2
  • Price: From $24.00
  • Form: Softgel capsule
  • Serving size: 1 softgel
  • Servings per container: 180
  • Amount of vitamin D: 50 mcg (2,000 IU)
  • Other ingredients: Wild Alaskan sockeye salmon oil

The vitamin D supplement from Vital Choice comes in the best form of vitamin D for absorption—the softgel capsule. What’s more, it also contains salmon oil, a non-GMO mixed tocopherol rich in healthy Omega-3 fatty acids. Each softgel has as much as 50 mcg of vitamin D3 and 24 mcg of Omega-3. 

The healthy fats from the salmon oils dissolve incredibly easily, all thanks to the supplement’s softgel form. This is not the case with most other supplements that try to deliver healthy fats to your body using regular capsules. 

What’s more, we believe this one of the best D3 supplement products on the market for all the numerous benefits it brings, including better bone strength, improved brain function, and a stronger immune system.

In the end, we’ve noticed that many customers are happy with the softgel capsules this company makes. They feel it’s the best form of vitamin D, not only for the high absorption but also for how easy it is to swallow the capsules.

PROS:
  • No artificial preservatives
  • Free of dairy, starch, yeast, wheat, sugar, and soy
  • Gluten-free
  • Replacement products and refunds
  • Rich in Omega-3 fatty acids
CONS:
  • Some dislike the fishy aftertaste

8. Country Life Vitamin D3 Review

OVERALL RATING 9.1
  • Price: From $9.29
  • Form: Softgel capsule
  • Serving size: 1 softgel
  • Servings per container: 60 or 200 softgels
  • Amount of vitamin D: 125 mcg (5,000 IU)
  • Other ingredients: Bovine gelatin, glycerin, medium-chain triglycerides

If you’re looking for gluten-free vitamin D supplements, then this is one of the best vitamin D brands for you. The Country Life Vitamin D-3 supplement is entirely gluten-free and contains no soy, yeast, corn, milk, wheat, sugar, salt, preservatives, or artificial sweeteners. 

All of this makes it perfect for most diets and lifestyles, with the only exceptions being vegans, as this supplement is made from lanolin oil, which comes from sheep’s wool. 

This is also one of the best calcium vitamin D supplement products on the market as it helps your body in calcium absorption. 

The supplement comes in 25 mcg (1,000 IU), 62.5 mcg (2,500 IU), and 250 mcg (10,000 IU) doses, as well as in the form of spray with 50 mcg vitamin D-3 and an added strawberry flavor. That way, most people can benefit from one of the top vitamin D supplements on the market, regardless of their specific needs.

PROS:
  • Incredibly affordable
  • Very allergy friendly
  • Comes in recyclable packaging
  • Choose a dose between 25–250 mcg
  • Free of gluten, yeast, corn, wheat, soy, milk, salt, sugar, and preservatives
CONS:
  • Non-vegan
  • The softgel capsules tend to stick together

9. Designs for Health Liposomal D Supreme Review

OVERALL RATING 8.9
  • Price: $33.35 per fluid ounce
  • Form: Liquid
  • Serving size: 1 pump
  • Servings per container: 90
  • Amount of vitamin D: 125 mcg (5,000 IU)
  • Other ingredients: Vitamin K

Designs for Health Liposomal D Supreme is a top-rated vitamin D supplement that contains large quantities of both vitamin D and K. Their symbiosis is incredibly useful, as together, they benefit your immune system, bone health, and the calcium balance in your body. 

More importantly, this product uses liposomes, tiny spheres of fat that carry vitamin D and other nutrients. This is important as liposomal forms are better absorbed in the body, according to independent medical studies. 

The supplement is highly rated by consumers, which is more than evident from the numerous positive reviews customers leave all the time. However, we also believe that this is one of the best vitamin D liquid supplement brands for a single crucial reason — tens of thousands of physicians trust them.

PROS:
  • High doses of both vitamin D and K
  • Good for the immune system, bone health, and calcium balance in the body
  • Trusted by more than 50,000 health practitioners
  • Free of gluten, dairy, and soy
  • Highly-recyclable amber glass packaging
CONS:
  • Some customers don’t appreciate the price
  • Some users complained of heartburn after using the supplement

10. Nordic Naturals Zero Sugar Vitamin D3 Gummies Review

OVERALL RATING 8.8
  • Price: From $16.75
  • Form: Gummies
  • Serving size: 1 gummy
  • Servings per container: 60 or 120 gummies
  • Amount of vitamin D: 25 mcg (1,000 IU)
  • Other ingredients: Natural flavor, xylitol, carnauba wax, pectin

If you’re looking for the best vitamin D supplement for weight loss, then these delicious vitamin D gummies might be ideal products for you. They don’t contain any sugar, and each gummy has only five calories in total. As some studies state that vitamin D might be beneficial in weight loss, these gummies can be a great supplement to your diet. 

What’s more, they contain about 125% of your daily vitamin D needs, so they should bring benefits to your bones and immune system. 

It’s also worth noting that this is the best brand for vitamin D3 supplement gummies, as almost all others add sugar. This makes the Nordic Naturals product sound perfect, but it’s essential to know that it contains xylitol, which is known to cause minor digestive issues in some people. Thankfully, these issues are quite sporadic, so you are unlikely to experience them. 

Despite that, we still believe this is one of the best over-the-counter vitamin D supplements on the market, so if you’re looking for an easy-to-swallow gummy with enough vitamin D3 for the whole day, then the Nordic Naturals gummies are the perfect choice for you.

PROS:
  • High absorption
  • Delicious wild berry flavoring
  • 100% satisfaction guarantee
  • High-quality vitamin D brand
  • No sugar, gluten, milk derivatives, or artificial flavors and colors
CONS:
  • Too sweet for some customers
  • Some might experience minor digestive issues

How to Choose the Best Vitamin D Supplement

Now that you’ve read our vitamin D supplement reviews, it’s time to look at ways of choosing the best product for your needs. What follows is a detailed buyer’s guide that covers all the important details about vitamin D supplements. 

Things to Know Beforehand

First and foremost, you need to test your vitamin D levels before taking any high-quality vitamin D supplement. You need to do a blood test as it’s the only way to know if your vitamin D levels are insufficient, deficient, or sufficient. 

This is very important as it’s the only way to determine the dosage that will benefit you the most, especially if you are highly deficient in vitamin D. Naturally, most people only have slight deficiencies, which means that a good vitamin D supplement of about 10 mcg should be sufficient. It’s not advisable to take more than 100 mcg per day if you don’t suffer from a severe vitamin D deficiency. 

Consider the Form of Vitamin D

When looking for the best vitamin D supplement brand, we also need to consider the form of vitamin D it offers. There are two forms of vitamin D: vitamin D2 or ergocalciferol and vitamin D3 or cholecalciferol. There aren’t too many differences between the two, except that vitamin D2 comes from plants and fortified foods, while vitamin D3 comes from animal products. 

It’s worth noting that our bodies naturally produce vitamin D3 when exposed to the sun, but vitamin D2 is much cheaper to make. However, many claim that vitamin D3  works better at higher doses. Some studies support this, albeit the difference is not very significant.

When we consider all of this, it’s hard to state which one is the best form of vitamin D supplement. However, most health professionals recommend taking vitamin D3 supplements. 

Choose Your Preferred Supplement Form

The form of the actual vitamin matters, but so does the form of the supplement. By that, we mean whether the vitamin D comes in tablets, liquids, or sprays. There’s no single best form here—all are quite good. It could be argued that softgel capsules are better than regular pills, but many people don’t like them. 

So, when looking for high-quality vitamin D, you need to consider your personal preferences and medical needs. Here’s what you need to know:

  • Pills are more common
  • Softgels are often easier to swallow than pills
  • Liquids and sprays are easily mixed with food or water 

Look for Third-Party Certifications

The law requires medications to have third-party verification, but this is not the case with most supplements. This means that even the very best supplement for vitamin D deficiency might not be tested by a third party. 

That’s why it’s crucial to check that a notable third-party organization has reviewed the product. Look for verifications from names like:

  • ConsumerLab.com (CL)
  • Good Manufacturing Practices (GMP)
  • United States Pharmacopeia (USP)
  •  Dietary Supplement Verification Program (DVSP/USP)
  •  American National Standards Institute (ANSI)
  • Natural Products Association (NPA)

Know Your Dosage

It doesn’t really matter if you’re getting the top vitamin D supplement on the market if the dosage isn’t right for you. Children and adults up to 70 should take about 600 IU of vitamin D, and people older than 70 around 800 IU. However, dosages of 1,000–2,000 IU are common, especially during winter or any other time when you aren’t getting enough sunlight. 

You can take a supplement with a higher dosage, but you shouldn’t go above 4,000 IU, which is the upper recommended limit. For anything above, you need to consult your doctor. Only people with severe deficiencies need to look for the best vitamin D supplement of 5,000 IU or more, but only after consulting their doctor. 

Check for Allergens

Most of the supplements we recommend are free of most allergens, but it’s still important for you to check the labels. If you have a common allergy, it’s quite likely that you’ll run into a supplement that uses the ingredient you’re allergic to. Some supplements are also not gluten-free, or they may contain some other ingredients you don’t tolerate. Therefore, always read the label before deciding to buy. It’s typically available online for all supplements. 

Final Thoughts

So there you go—detailed reviews of the best vitamin D supplement products on the market. Now, all you have to do is make a decision. However, make sure to consult your doctor beforehand, as supplements shouldn’t be taken lightly.

FAQs

What are the symptoms of low vitamin D?

It’s hard to tell, as symptoms often depend on the severity of your vitamin D deficiency. What’s more, symptoms of low vitamin D levels are more noticeable in children than in adults. If they are deficient in vitamin D, they can experience weakness, pain, and soreness in their muscles. On some rarer occasions, severe vitamin D deficiency can lead to rickets. Even though the symptoms are rare in adults, you can still experience fatigue, muscle weakness, bone pain, mood swings, depression, etc.

What strength vitamin D should I take?

The amount you need depends on your age, race, sun exposure, the clothes you wear, location, and even race. It also depends on whether or not you have a vitamin D deficiency. As for healthy adults, the US Institute of Medicine states that the average daily intake of vitamin D needs to be between 10–20 mcg or 400–800 IU. 

However, if you were looking for the best vitamin D3 supplement in 2020, you were still supposed to check with your doctor to see how much vitamin D you needed. Your doctor is always the one who can make the best suggestions. It’s also worth noting that people with severe deficiencies need to take much more than the recommended daily average.

What is the difference between vitamin D and vitamin D three?

First of all, it’s important to note that we are looking at the difference between vitamin D2 and vitamin D3, the two forms of vitamin D. The main difference between the two is that vitamin D2 is found in plants and fortified foods, making it less expensive, while vitamin D3 comes from animal-sourced foods like fish oil and egg yolk. More importantly, you can get vitamin D3 naturally, as our skin makes it while we’re exposed to the sun.

Both forms of vitamin D do the same thing, but D3 is often cited as being the best quality vitamin D, as some studies deem it superior. However, scientists are still uncertain. Moreover, another significant difference is that vitamin D2 tends to degrade more when stored, but there are no studies at the moment that show if this is harmful to our health.

Should I take vitamin D or D3?

The term “vitamin D” is a misnomer, as almost no supplement is a vitamin D supplement. This is because it comes in two forms, vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). So, when you’re asking which vitamin D to take, you’re inquiring about the vitamins D2 and D3. 

It’s widely accepted that people can take either when looking for the best vitamin D supplement. Our bodies, or more specifically, our livers, process both vitamins in the same manner. Still, some studies have shown that vitamin D3 is slightly superior, but it’s also more expensive. However, most doctors always recommend D3 to their patients.

What is the most absorbable form of vitamin D?

The best answer we can give you is neither. The studies that tested how both types of vitamin D are absorbed found that both are almost the same. Even though vitamin D3 is often cited as slightly better than vitamin D2, it seems that vitamin D2 is absorbed with similar efficiency. However, it’s stated that more research is required to further test the bioavailability of vitamin D.

Which is the best vitamin D supplement?

The only certain thing that we can tell is that the recommended form of vitamin D is cholecalciferol, which we commonly know as vitamin D3. Even though vitamin D2 seems to be equally effective, D3 is still recommended, as it’s the form our bodies naturally make when exposed to sunlight.  

There’s no such thing as the best vitamin D supplement. It depends on your needs, what your doctor recommends, and numerous other factors like your age, race, et.
