Some things are just better together — and for vitamin D3 and vitamin K2, it’s theorized that they work synergistically to improve bone health, which has led companies to create D3 supplements with added K2.

However, if you’re vegan, there’s something you need to ensure; not only do the capsules need to be vegetable-based, but the vitamin D3 also needs to come from lichen, which is one of the two serious vegan sources of D3.

In this article, I’ve compiled six brands that are among the few that provide you with a combination of vegan vitamin D3 and K2.

Best Vegan D3 and K2 Supplements

1. Ora Organic Sol Food Vegan D3 + K2

Out of all the brands I’ll mention, Ora Organic is easily the most ethical and sustainable, and it’s 100% vegan.

On the other hand, it’s also a ‘premium’ brand, so the prices are a bit steeper.

Sol Food is Ora’s vitamin D3 and K2 formula, which is considered a high-potency formula with 5000 IUs of lichen-based D3, and 100 mcg of chickpea-based K2— which means you don’t have to take it every single day.

The other ingredients in the formula can be attributed to the chewable tablets, and they’re all organic, free from artificial fillers and flavors.

This includes the sugars that make the chewable tablets pleasantly sweet.

If you don’t mind paying extra for a brand that is considerably more ethical in both the human and animal sense, and that cares about the environment, then Ora Organic seems like the better choice.

2. Performance Lab Vegan D3 + K2

Performance Lab is not a vegan brand, but many of its products are vegan-certified, and they employ an interesting nutrient-delivery technology in their products.

This formula is not the most potent— but it comes with 1000 IUs and 50 mcg of K2 which are inserted into Performance Lab’s prebiotic-infused capsules that aim to improve digestion and gut health.

Unlike the previous option, the vitamin D3 content here is obtained from algae and comes in a liposomal format, which according to the brand, is a format that enables you to absorb the supplement’s content in a more streamlined way.

With that being said, this is not the cheapest brand considering some of the unique mechanisms I’ve mentioned, but it’s yet another viable choice.

3. Solaray Vegan D3 + K2

Solaray offers a potent formula that combines 5000 IUs of Vitamin D3 and 50 mcg of Vitamin K2. These ingredients have been meticulously sourced and rigorously tested for purity, potency, and identity.

A standout feature of Solaray is its dedication to ecological sustainability. It exclusively utilizes PCR resin bottles, made from plastics salvaged from oceans and landfills.

Moreover, Solaray is in a significant partnership with the non-profit organization, One Tree Planted, dedicated to global reforestation. Their joint mission is to achieve an ambitious target of planting one million trees by 2025.

Lastly, Solaray offers its product in two packaging sizes: a bottle with 60 capsules or one with 120 capsules. They stand behind the efficacy of their products, providing a 60-day money-back guarantee.

4. Zhou Nutrition Vegan D3 + K2

Zhou Nutrition, a brand stationed in the heart of Utah, offers a high-potency formula with 5000 IUs of vitamin D3, and 90 mcg of K2.

The company not only operates from Utah but also tests its products within a GMP-certified facility in the same location.

If you prefer smaller capsules that are easy to swallow, approximately one inch in size, Zhou’s formula caters to this need.

Upon inspecting the brand’s profile on Trustpilot, I discovered that Zhou Nutrition boasts numerous positive reviews.

Unlike many supplement brands, they have a significant amount of favorable feedback— and this is telling of the company’s fair practices.

5. MRM Nutrition Vegan D3 + K2

MRM Nutrition, a brand that has been in operation since 1996, is somewhat of a hidden gem in the supplement market. Despite not being widely recognized, it offers one of the most affordable D3 and K2 vitamins, costing just $0.16 per serving for a 60-capsule supply.

While their formula might not be the most potent on the market, it does deliver a respectable 2500 IUs of Vitamin D3 and 80 mcg of K2 per serving.

In 2014, MRM embarked on a path toward sustainability that began with earning vegan certification for all of their products through Vegan Action (vegan.org). Around the same time, they started hosting beach cleanups in San Diego County, marking the onset of their commitment to environmental stewardship.

Fast forward to the present day, MRM embraces an eco-friendly manufacturing process. They use PCR bottles, manufactured from recycled plastics, and recyclable pouches.

Furthermore, they’ve eliminated the use of plastic neckbands on all of their products, illustrating their dedicated efforts toward a sustainable future.

6. Nested Naturals Vegan D3 + K2

Nested Naturals, a recognized vegan brand, offers a potent formula. This includes 5000 IUs of vitamin D3, 100 mcg of K2, and an added component—250mg of nettle leaf extract.

The inclusion of nettle leaf extract is a unique touch. It’s a plant believed to support skin and bone health, thanks to its beneficial contents like amino acids, proteins, flavonoids, and important minerals such as iron, calcium, magnesium, potassium, and zinc.

Plus, it’s a good source of vitamin K, a fact that’s been touched on in various studies.

When it comes to product testing, Nested Naturals has a clear four-step process that involves herb identification, checking microbial counts, testing for heavy metals, and verifying potency.

What’s more, they offer a lifetime guarantee. This means customers can request a refund anytime—a sign of the company’s trust in their own products.

Do Vegans Need To Supplement Vitamin D3 and K2?

It might be necessary for vegans to consider supplementing with vitamins D3 and K2, but it largely depends on their individual circumstances. Here’s a bit more context.

Vitamin D3 is primarily sourced from animals, including us, when our skin is exposed to sunlight. Studies have found that Vitamin D3 can contribute to a longer lifespan, alleviate menstrual pain, and help ward off respiratory infections.

If you’re not getting enough sunlight, a daily supplement of 2,000 IU of Vitamin D, preferably taken with your largest meal, is usually recommended.

Interestingly, just like us, mushrooms also produce Vitamin D when exposed to sunlight.

However, the mushrooms we typically find in our grocery stores are usually grown in the dark and therefore, don’t have any vitamin D. Tanning beds aren’t a good solution either. They’re not just ineffective at producing vitamin D but also increase the risk of melanoma, a type of skin cancer.

It’s important to remember that these benefits are largely associated with Vitamin D3, which comes from plants and animals. Vitamin D2, derived from yeast and mushrooms, does not seem to have the same effects.

Shifting gears to Vitamin K, it may not be as well-known as Vitamins A, B, C, D, and E. The ‘K’ in Vitamin K is derived from ‘Koagulation’, which is German for coagulation.

Besides its crucial role in blood clotting, Vitamin K is believed to have significant implications for bone, heart, and brain health.

The connection between Vitamin K and bone health has been a matter of contention.

However, after disregarding studies with questionable integrity, it becomes clear that there’s no solid evidence suggesting Vitamin K supplements enhance bone mineral density or inhibit fractures.

For heart health, Vitamin K was once considered to possibly deter calcium accumulation in our arteries, maintaining their flexibility. Nonetheless, thorough research has shown no consistent proof that Vitamin K halts the advance of artery calcification or hardening.

Vitamin K is readily sourced from our diet, especially from dark green leafy vegetables. Though meat, dairy, and eggs do provide Vitamin K2, once your intake of K1 from plants is sufficient, there’s no recognized requirement for K2. If you’re worried about a K2 deficit, don’t be. The bacteria in our gut produce Vitamin K2, which is also present in fermented foods.

Regarding supplements, if your diet is rich in green vegetables, Vitamin K supplements are unnecessary. Some studies have also pointed out issues with Vitamin K supplements, such as incorrect labeling and contamination.

Lastly, it’s worth noting that our bodies can transform the Vitamin K1 from greens into Vitamin K2, even though K2 is naturally found in higher concentrations in specific tissues, like the brain.

Research involving centenarians has shown that higher blood levels of Vitamin K1, derived from vegetables, are associated with better cognitive health. This could be due to other beneficial nutrients in green vegetables, such as lutein, known to boost cognitive performance.

So, the bottom line is to consume plenty of greens and soak up some sunshine when possible! If your sun exposure is limited, a Vitamin D supplement could be beneficial.

For Vitamin K, if you’re consuming an adequate amount of leafy greens, you’re good to go. There’s no recognized need for extra Vitamin K2, and your body has a clever way of producing it, just in case your greens intake slips for a day or two.
