Best Vegan Vitamin D3 With K2 for Bone and Immune Health

The best vegan with K2 vitamin D3 for most buyers is the Sports Research Vegan Vitamin D3 + K2 with Coconut Oil, a 60-count softgel that pairs 125 mcg (5000 IU) of lichen-derived D3 with 100 mcg of MK-7. If you want the highest K2 figure in this comparison, the Naturalis algae-sourced softgel delivers 120 mcg of MK-7 per capsule and sits at the cheapest price position of the five.

Best vegan with K2 vitamin D3 at a glance

Who this guide is not for

If you're looking for a chewable, a gummy, or a liquid dropper, close the tab. Every bottle here is a softgel or a capsule taken once daily with food. If you follow a strict low-fat diet, note that four of the five picks use an oil carrier (coconut MCT or olive oil), which is deliberate: vitamin D3 is fat-soluble and the oil is there to help absorption. If you cannot swallow softgels, only two picks are dry capsules (MRM and NATURELO). And if you want a K2 form other than MK-7, this shortlist won't help you: every product here uses MK-7 rather than MK-4.

How I screened the shortlist

I started with vegan D3+K2 softgels and capsules in the Vitamin D3 & K2 Combinations category, then cut anything that didn't clearly disclose both a plant-based D3 source and a specific K2 form. Every pick left standing uses either lichen-derived or algae-derived D3, and every pick uses K2 as MK-7 rather than MK-4. Bottle count was fixed at 60 to keep servings comparable across the set.

From there, I compared the published specifications side by side rather than reading the marketing paragraphs. The four data points that decide most of this category are:

1. The D3 dose per softgel (where stated).
2. The K2 dose per softgel (where stated).
3. The carrier oil, since D3 is fat-soluble.
4. Third-party certifications: NSF, Non-GMO Project, Vegan Certified.

Two picks (MRM and NATURELO) do not state a dose figure in the listing data I could see, so I've been careful not to assume one. That doesn't rule them out; it changes what they're good for.

What actually decides a vegan D3+K2

Most guides in this category compare bottle count and price. That's not what decides it. What decides it is the pairing of a stated D3 dose with a stated K2 dose, in a form your body can actually absorb, from a source you can verify.

Here's the trick with vegan D3. Standard D3 (cholecalciferol) is made from lanolin, which is a sheep-wool byproduct, so it's not vegan. The plant-based alternatives are lichen (a symbiosis of algae and fungi) or a specific microalgae like Nannochloropsis oceanica. Sports Research, NatureWise, MRM and NATURELO all say lichen. Naturalis says microalgae. Both are legitimate vegan sources; there's no meaningful hierarchy between them for a daily dose.

K2 is a different question. MK-7 has a longer half-life in the bloodstream than MK-4, which is why every pick here uses it. What varies is the dose. Sports Research and NatureWise both claim 100 mcg. Naturalis claims 120 mcg. MRM and NATURELO state the form but not the milligram figure in the listing, so treat their K2 as present but unquantified.

The carrier matters too. D3 is fat-soluble, so an oil-based softgel is generally easier to absorb than a dry capsule taken on an empty stomach. Sports Research uses coconut MCT oil. NatureWise and Naturalis both use olive oil. MRM and NATURELO are dry capsules.

1. Sports Research Vegan Vitamin D3 + K2 — Best overall

A 5000 IU vegan D3 paired with 100 mcg of MK-7 in a coconut MCT softgel, with three named certifications.

Best for: a daily 5000 IU dose in a certified coconut MCT softgel Skip it if: you want olive oil or a higher K2 figure

Sports Research is the pick that lines up most cleanly on the four criteria that decide this category. The brand states 125 mcg (5000 IU) of D3 sourced from lichen and 100 mcg of K2 as MK-7 derived from fermented chickpeas, delivered in a coconut MCT softgel weighing 1.1 oz per 60-count bottle. It's Vegan Certified, Non-GMO Project Verified, and stated as free from carrageenan, gluten and soy. Sports Research also says the softgel is a "Plantgel", which is a plant-based capsule shell rather than gelatin.

Within this set of five, Sports Research is the one buyers choose most often here by a wide margin: its sales rank is more than an order of magnitude ahead of the next pick. It sits in the premium price position, third of the four picks with price data. The trade-off against Naturalis is a lower K2 figure (100 mcg vs 120 mcg) at a higher price. The trade-off against NatureWise is coconut oil rather than olive oil as the carrier. Neither swap is a reason to move off the default unless you have a specific preference.

Pros:

• Stated 125 mcg (5000 IU) D3 and 100 mcg MK-7
• Coconut MCT carrier for fat-soluble absorption
• Vegan Certified and Non-GMO Project Verified
• Lichen-derived D3, chickpea-fermented K2
• Highest sales velocity of the five picks

Cons:

• Premium price position within this set
• K2 figure lower than the 120 mcg Naturalis claims
• Coconut oil unsuitable if you avoid it

2. NatureWise Vegan Vitamin D3 K2 Supplement — Best for pros

Same headline dose as the overall winner, in an NSF-certified formulation with cold-pressed olive oil.

Best for: buyers who want NSF-certified contents and olive oil Skip it if: you cannot tolerate olives or want algae-based D3

NatureWise runs the same 5000 IU D3 and 100 mcg K2 as MK-7 targets as Sports Research, but in a different carrier and with a different certification stack. The D3 comes from VegaDelight, a lichen-sourced ingredient. The K2 is branded VitaMK7. The carrier is organic cold-pressed olive oil, processed without heat or hexanes according to the listing. The bottle weighs 1.12 oz across 60 softgels.

The reason this is the pick for pros: NatureWise states the contents are NSF-certified, meaning the finished product has been tested by a third party for accuracy of the label and absence of contamination at defined thresholds. That's a stricter check than "manufactured in a cGMP facility", which is a facility standard rather than a batch test. If you're an athlete subject to testing, or you buy supplements for someone who is, NSF certification is the specification worth paying attention to.

The trade-offs are two. NatureWise sells more slowly than Sports Research in this set. And olive oil is a more allergenic carrier than coconut MCT for a small number of buyers.

Pros:

• Stated 5000 IU D3 and 100 mcg MK-7
• NSF certification on the finished contents
• Organic cold-pressed olive oil carrier
• Free from wheat, egg, soy, dairy and nuts
• Entry price position in this set

Cons:

• Olive oil unsuitable for a small allergy subset
• Slower seller than the overall winner
• Lichen-only D3 source (no algae option)

3. Naturalis Vegan Vitamin D3+K2 from Algae — Best budget pick

The highest stated K2 figure in this set, using algae-derived D3, at the cheapest of the four priced picks.

Best for: the highest K2 figure in the set at the cheapest position Skip it if: you prefer lichen-derived D3 or a bigger brand

Naturalis is the only pick in this shortlist that sources its D3 from microalgae (Nannochloropsis oceanica) rather than lichen. Everything else is comparable to the leaders on paper: 125 mcg (5000 IU) of D3, an organic extra virgin olive oil carrier, 60 softgels per bottle at a 28.3 g pack weight, one softgel per day. The K2 comes from biofermented natto, again as MK-7.

Where it separates from Sports Research and NatureWise is the K2 figure. Naturalis claims 120 mcg of MK-7 per softgel, which is 20% higher than the two 100 mcg options. Whether that difference is meaningful for you is a conversation for a clinician, but it is the largest K2 dose in this shortlist and it comes at the cheapest price position of the four picks with price data. Vegan Society Certified is also called out on the label.

The trade-off is brand footprint. Naturalis is a smaller name than Sports Research or NatureWise, and its sales velocity in this set reflects that. If brand familiarity matters to you, Sports Research is the safer default.

Pros:

• 120 mcg MK-7 per softgel, highest here
• Algae-derived D3, the only such pick
• Organic olive oil carrier
• Vegan Society Certified, Non-GMO, gluten-free
• Cheapest of the four picks with price data

Cons:

• Smallest brand footprint in this set
• Lower sales velocity than Sports Research
• Olive oil rules it out for a small subset

4. MRM Nutrition Vegan Vitamin D3 & K2 — Best large-capacity

A lichen-sourced D3 and MK-7 capsule from a brand running since 1996, listed as 60 servings.

Best for: a simple lichen D3 and MK-7 capsule from a long-running brand Skip it if: you want a stated dose or a published carrier oil

MRM is a capsule rather than a softgel, and it's from a brand that describes itself as owned by a clinical dietitian and biochemist and running since 1996. The listing states D3 as cholecalciferol sourced from lichen, and K2 as MK-7. The 60-count bottle carries a 2017 release date on Amazon, so this is a formulation that has been on shelf and in inventory for years rather than a new SKU.

The reason it's here and not higher: the listing data does not state the specific milligram figures for D3 or K2, and it does not name a carrier oil. That's a real gap. If you're buying on the strength of the numbers, you can't compare MRM on the same footing as Sports Research, NatureWise or Naturalis. If you're buying on brand track record and a preference for a plain vegan capsule you can take without food, MRM is a reasonable holding pattern. Its trade-off against the others is exactly this: fewer published specifications, and no price band in the data I have.

Pros:

• Lichen-derived D3, MK-7 K2 form
• Established brand with a 2017-onward listing
• Vegan capsule format, no oil carrier needed
• Positioned in the Calcium subcategory
• Simple once-daily protocol

Cons:

• No stated D3 or K2 milligram figure in the listing
• No published carrier oil
• Slower seller than the top three picks

5. NATURELO Vitamin D3 K2 — Best premium

A dry vegan capsule from a clean-label house brand, D3 from wild-harvested lichen, K2 as MK-7.

Best for: capsule format from a clean-label vegan house brand Skip it if: you prefer a softgel with an oil carrier for absorption

NATURELO's D3 K2 is a 60-count capsule at the premium price position in this set. The D3 is stated as plant-based, sustainably sourced from wild-harvested lichen. The K2 is called out as MK-7, and the bottle is described as Non-GMO, vegetarian, vegan, gluten-free, and manufactured in a GMP-compliant facility. Bottle weight is 28.3 g and dimensions run 4.3 x 2.31 x 2.31 in, taller than the Sports Research and NatureWise softgel bottles.

What NATURELO is buying you is a clean-label house brand identity across a broad supplement range, rather than a specialist D3 formulation. What it isn't giving you, based on the listing data, is a specific milligram figure for either D3 or K2, and it's a dry capsule rather than an oil-based softgel. For a fat-soluble vitamin, that means taking it with a meal that contains some fat is more important than for the softgel picks. Its trade-off against the winner is the highest price position in the set for fewer stated numbers on the label.

Pros:

• Wild-harvested lichen D3
• K2 as MK-7, the bioactive form
• Clean-label credentials across the range
• Vegan, vegetarian and gluten-free
• GMP-compliant manufacturing

Cons:

• Premium price position in the set
• No stated D3 or K2 milligram figure in the listing
• Dry capsule, no carrier oil for absorption
• Slower seller than Sports Research

Carrier oil, dose and K2 form: how the five compare

Three of the five picks are oil-based softgels, and two are dry capsules. That single split matters more than the branding does, because it changes how you take the product. Softgels can be taken with or without food and still absorb well, because the D3 is already dissolved in the oil. Dry capsules should be taken with a meal that contains some fat.

Inside the softgel group, the split is coconut MCT (Sports Research) versus olive oil (NatureWise and Naturalis). Neither is objectively better; they're different fats. Coconut MCT is more neutral in aftertaste and shorter-chain, which some users find easier on digestion. Olive oil is a polyunsaturated fat with its own literature on cardiovascular health, and cold-pressed olive oil preserves more of its native antioxidants than heat-extracted versions.

On dose, three picks state 5000 IU of D3: Sports Research, NatureWise and Naturalis. Two do not: MRM and NATURELO. On K2, Naturalis states 120 mcg, Sports Research and NatureWise state 100 mcg, and MRM and NATURELO state the form (MK-7) without a milligram number in the listing data.

What the listings do not tell you

Two things the product listings won't tell you clearly, and that are worth knowing before you press buy.

• A 5000 IU dose is a common label figure, not a universal recommendation. Vegan D3+K2 bottles cluster around this number because it fits most adult maintenance protocols, but individual needs vary with sun exposure, latitude, skin tone, age and existing blood levels. A serum 25-hydroxyvitamin D test is the only way to know whether you need this dose, more, less, or none.
• K2 interacts with anticoagulant medication. Warfarin works by antagonising vitamin K, so any K2 supplement is a conversation to have with the prescribing clinician before you add one. This isn't a warning specific to any pick here; it applies to K2 as a category.

Two things you can verify yourself on the product page before you commit: the D3 source (lichen or algae, not lanolin) and the K2 form (MK-7, not MK-4). If either is missing from the listing you're reading, that's a signal to keep looking.

Who should skip this category entirely?

Skip a combined D3+K2 supplement if any of the following applies. If you take a prescription anticoagulant such as warfarin, K2 changes the calculation and the decision belongs with your doctor, not with an Amazon listing. If your most recent 25-hydroxyvitamin D result was above the reference range, adding more D3 daily is the wrong direction. If you already take a separate D3 dose you're happy with, a combined product doubles up and complicates dosing without benefit.

If you're pregnant, breastfeeding, or dosing a child, the numbers change enough that a paediatrician or obstetrician should be the source of the recommendation. And if your goal is simply "I want a vegan multivitamin", a combined D3+K2 is more targeted than you need; a broad vegan multi will cover D3 alongside other gaps for less friction.

How long does a bottle of 60 softgels last?

Every pick in this shortlist is a 60-count bottle taken once daily. At that rate, a bottle lasts two months. Two bottles is a four-month supply. That works out to roughly three bottles a year with a small buffer for missed days. Set a reorder reminder for around week seven if you're on a strict daily protocol.

If you split a bottle with a partner, halve that number. If you dose every other day (some clinicians recommend this once serum levels are stable), a bottle stretches to four months per person.

The verdict

The Sports Research Vegan Vitamin D3 + K2 is the right pick for most buyers because it lines up the four criteria that decide this category: a stated 125 mcg (5000 IU) D3 dose from lichen, a stated 100 mcg K2 (MK-7) figure, a coconut MCT oil carrier for a fat-soluble vitamin, and a stack of three certifications (Vegan Certified, Non-GMO Project Verified, and free from common allergens by the manufacturer's statement). Its sales velocity is more than an order of magnitude ahead of any other pick in this set, which tells you buyers keep reordering.

Two conditions flip the recommendation. First: if you specifically want the highest K2 figure in this shortlist, Naturalis states 120 mcg of MK-7 per softgel at the cheapest price position, using algae-derived D3 and organic olive oil. Second: if you or someone you buy for is subject to sport-testing, NatureWise's NSF-certified contents matter more than any dose difference. MRM and NATURELO are honest holding patterns for buyers who want a dry capsule from an established brand, but neither states the milligram figures the top three do.

FAQ

What is the best vegan D3 with K2 for most adults?

The best vegan D3 with K2 for most adults, based on stated dose, carrier oil, and certification stack, is the Sports Research Vegan Vitamin D3 + K2 with Coconut Oil. It delivers 125 mcg (5000 IU) of lichen-derived D3 and 100 mcg of K2 as MK-7 in a coconut MCT softgel, and it carries Vegan Certified and Non-GMO Project Verified marks on the label.

Is a vegan D3+K2 worth it over a plain vegan D3?

A vegan D3+K2 is worth it over a plain vegan D3 if you want the two vitamins in one softgel and you're comfortable with the K2 dose the bottle carries. The two are studied together for calcium metabolism and bone support in the manufacturer literature. If you already take K2 separately, or you take an anticoagulant, a plain D3 is the simpler choice.

How much K2 as MK-7 do these vegan D3 supplements contain?

The K2 as MK-7 dose in these vegan D3 supplements varies. Sports Research and NatureWise both state 100 mcg per softgel. Naturalis states 120 mcg per softgel, the highest figure in this comparison. MRM and NATURELO state the K2 form (MK-7) on the label but do not publish a specific milligram figure in the listing data, so treat their K2 as present but unquantified.

Sports Research vs Naturalis: which vegan D3+K2 wins?

Sports Research vs Naturalis comes down to two variables. Sports Research states a lower K2 dose (100 mcg vs 120 mcg) at a premium price position, but it sells far more copies and uses coconut MCT rather than olive oil. Naturalis states the higher K2 figure at the cheapest position and uses algae-derived D3, the only pick here that does. Pick Sports Research for defaults, Naturalis for K2.

What mistake do first-time vegan D3+K2 buyers make?

The mistake first-time vegan D3+K2 buyers make is ignoring the carrier. Vitamin D3 is fat-soluble, which is why four of the five picks use an oil carrier: coconut MCT or olive oil. A dry capsule taken on an empty stomach absorbs less well than the same dose in an oil softgel, or than a dry capsule taken with a fatty meal. Match the format to how you actually take supplements.

If you have been putting off the decision because the labels blur together, start with the Sports Research softgel: it is the pick where every criterion that matters in this category is written on the bottle, and it is the one buyers here keep coming back for. Two months later you will know whether 5000 IU D3 and 100 mcg MK-7 suits you, or whether you want to try the 120 mcg Naturalis or the NSF-certified NatureWise on the next reorder. Confirm the dose with a clinician if you take other medication, and keep the empty bottle so the next reorder is a copy-and-paste, not a fresh comparison.
