2023’s Best
Vitamin D3 Supplements

Our Top Picks
Our experts' top Vitamin D3 + K2 picks of 2023 based on quality, effectiveness, availability, and value.

What To Look For
We'll share a few things to look for and consider when purchasing a Vitamin D3 supplement.

Vitamin K2

Vitamin D3


Vitamin D supplements come in two forms: vitamin D2 and D3. Both types are beneficial in treating vitamin D insufficiency, however D3 is easier to absorb and more effective than D2.

Vitamin D3 in conjunction with Vitamin K2 helps to guarantee that the calcium delivered by Vitamin D3 is delivered to your bones and not deposited in your arteries.

What are vitamins D3 and K2?

Here's why D3 is the best form of vitamin D, and why D3 works best when combined with vitamin K2.

Vitamin D3 Benefits

Boosts Immune System

Low Vitamin D levels may make you more susceptible to infectious diseases. 

Stronger Bones

Strengthens and protects weakened bones, especially when combined with Vitamin K2.

Cognitive Improvements

May increase cognitive capacity making it easier to process new information.

Slows Aging

Low levels of Vitamin D have been shown to cause premature aging. 

Overall Health

Studies have shown Vitamin D supplements may reduce the risk of certain types of cancer.

Gut Health

Studies have shown symptom reduction in people with IBS.


#1: Vitamin D3 + K2

from NativePath







NativePath D3+K2 is formulated with only vitamins D3 and K2 in an organic MCT oil base, making it the purest and most easily-absorbed product on this list. It fosters cardiovascular health, a healthy mood, energy and cognitive function. This makes it by far the most effective supplement on our list. Just 30 ml provides a month’s worth of dosage. NativePath D3+K2 Tincture is #1 on our list as the most all-around, complete vitamin D3 with K2 supplement.

Nanoemulsified D3K2

from Quicksilver







Nanoemulsified Vitamin D3/K2 was developed to render both fat-soluble vitamins highly absorbable. Each 0.5 mL delivers 2500 IU of vitamin D3 and 90 mcg of vitamin K2. A serving is one pump. Each bottle contains 100 servings. Though this is one of the best D3K2 supplements on the market, the price is rather high. Perhaps most importantly, users have complained that it has a particularly bad taste and burning sensation when swallowed. 


  • Emulsified for better absorption
  • 2500 IU of vitamin D3
  • Third party verified
  • 90 mcg of vitamin K2
  • Expensive, pump is awkward.
  • Users report foul taste

This is a very high-quality product that delivers a very high concentration of vitamin D3. The pump can be troublesome if kept in a pocket or purse. Still, it's a good choice if you're able to get past the taste and willing to pay the price for a highly refined product.


#3: D3 & K2 Vitamin

from Dr. Berg







Dr. Berg's D3 & K2 Vitamins score high on our list, thanks to the brand's dedicated focus on all-natural and keto-friendly solutions. To boot, their formulation offers a robust dosage of 250mg of Vitamin D3 & 100 mcg of Vitamin K2. However, its limited 30-day money-back guarantee didn't do it any favors. This is a strong overall supplement. It contains proper dosages of high-quality ingredients and lacks artificial fillers. That's why it earns the #3 spot on our list.


  • 10,000 IU Vitamin D3 per serving
  • No additives or fillers
  • 100 mcg Vitamin K2
  • No "off" flavors
  • Lacks Absorption-boosting Fats
  • Extremely Limited 30-day Guarantee

Dr. Berg's D3 & K2 Vitamins score high on our list, thanks to the brand's dedicated focus on all-natural and keto-friendly solutions. It contains the highest dosage of vitamin D3 on our list and is highly pure, with no additives or fillers. However, it has a relatively short money-back guarantee, and is not formulated with any oils or lipids, which may limit its absorptive capacity.


#4: Vitamin K2 + D3

from Bronson







Coming in at number 4 on our list is Vitamin D3+K2 by Bronson. We were impressed by the dosage, with high levels of both D3 and K2. But there is some confusion over which type of Vitamin K they use, which could affect its efficiency. Additionally, fillers like magnesium stearate (which has been suggested to have adverse health effects) are listed as ingredients. Despite those minor disappointments, their 365-day return policy is the best on our list.


  • 1-year Return Policy
  • GMO-, gluten-, dairy-, and soy-free
  • 125 mcg Vitamin D3
  • Plenty of K2
  • Contains Fillers
  • Not third party tested

This product contains a high dose and features a 1-year return policy. It’s GMO-, gluten-, dairy-, and soy-free, making it friendly for almost any consumer. It does contain magnesium stearate - a filler with a questionable reputation and track record. Therefore, though it can be an excellent supplement, it ends up at 4 on our list.


#5: Vitamin D3 & K2

from NOW Foods







Vitamin D-3 & K-2 by NOW Foods ranked in our top five list because it contains key ingredients like vitamin D3 and is ideal for shoppers on a budget, being the cheapest product on our list. However, that's about where the benefits end. Unlike the others on our list, which use MK-7, this product uses an inferior form of vitamin K2 known as MK-4. While it promotes healthy bones, MK-4 is less potent than MK-7. It also lacks healthy fats hence it is #5 on our list.


  • Easy to take – only 1 capsule daily
  • Cheap
  • Contains some vitamin C
  • Only a 30-day Return Policy
  • Lacks Fats to Aid in Absorption
  • Only 45 mcg K2

This product is highly affordable and convenient to take. It contains a good dosage of vitamin D3 at 1,000 IU, though it only has 45 mcg of K2, and not in the most absorptive or beneficial form. Furthermore, it only has a 30-day return policy. So despite its affordability, it ranks 5th on our list.


Are all Vitamin D3 + K2 supplement brands the same?

Absolutely not. D3 + K2 brands can differ greatly in their ingredients, purity, and effectiveness. Some things to consider:

  • What types of Vitamin K2 does the product contain (MK-7 is best)?
  • Does it contain beneficial fats, such as MCT oil, to aid in absorption? 
  • Are there any additives or artificial ingredients?
  • Is the product tested by a third party to ensure quality?
  • Does the company offer free shipping and money back guarantee?

Choosing one from the many available can be challenging. In our recently updated list of Vitamin D3+K2 supplements, NativePath took the top spot.
