You want vitamin D3 to pull calcium into your blood, and K2 to direct that calcium into your bones — not your arteries. The real challenge is finding a supplement whose dosage, form, and source fit your body and routine. Your choice depends on a few clear options: vegan or not, high or moderate dose, softgel or chewable, and how many days each bottle lasts.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Here are the best D3 K2 supplement for women picks, ranked by real customer satisfaction and clean, honest ingredient labels you can trust.
Our Picks at a Glance
How To Choose The Best D3 K2 Supplement for Women
Every pick here combines vitamin D3 with vitamin K2, but they differ in ways that change how you’ll feel taking them each day. Start with your own diet and lifestyle before you compare labels.
Match the D3 dose to your sun exposure
If you spend most of your day indoors or live somewhere with long winters, a higher 5,000 IU or 10,000 IU dose (IU stands for International Units, the standard measure of vitamin potency) helps you correct a deficiency faster. If you’re just maintaining healthy levels or get regular sunlight, a gentler 2,000 IU dose is often enough. Pay attention to your own needs — the right dose is about your body, not the biggest number on the bottle.
Check the K2 form and amount
Vitamin K2 comes in two main forms: MK-7 and MK-4. MK-7 stays in your body much longer and is the form most often studied for supporting bone health, which is why most of the picks here use it. The amount matters too — you’ll see K2 doses ranging from 75 mcg to 200 mcg (mcg means micrograms, a tiny unit of measure). Higher amounts generally mean more support for directing calcium.
Decide between vegan D3 or standard D3
Most standard D3 comes from lanolin, which is a natural oil found in sheep’s wool. Vegan D3 is sourced from lichen, a type of algae, and works just as well in the body. If you follow a plant-based diet, you’ll want to look for “vegan” or “lichen” on the label to make sure it fits your lifestyle.

In-Depth Reviews
1. Sports Research Vegan D3 + K2
Our pick — over 4.5★ from 54,000+ verified ratings; the strongest balance of quality and price.
The vegan-friendly crowd favorite that pairs lichen-based D3 with fermented chickpea K2 for clean, plant-based support.
This pick leads the list because it solves the biggest problem vegans face: most D3 comes from sheep’s wool lanolin. Sports Research sources its D3 from lichen and its K2 MK-7 from fermented chickpeas, so every 5,000 IU of D3 and 100 mcg of K2 is completely plant-based. The coconut MCT oil in each softgel helps your body absorb these fat-soluble vitamins, meaning you don’t need to time it with a fatty meal.
Quality is the thing everyone raves about here — it’s the most-praised aspect by far, with owners consistently noting how easy the small, odorless softgels are to swallow. Buyers report improved energy and mood during northern winters, and many say it raised their vitamin D levels without any stomach discomfort. The formula skips carrageenan, gluten, soy, and artificial fillers, and each batch is third-party tested and made in a cGMP-compliant US facility.
This bottle gives you 60 softgels — a two-month supply — so the per-day cost is slightly higher than the 300-count VEV Corefeel below. You’re paying for the certified vegan source and the brand’s reputation for consistency. It’s certified vegan and Non-GMO Project Verified, which is rare to find in one D3 K2 product.
What wins people over
- Certified vegan D3 from lichen, not lanolin
- Small, easy-to-swallow softgels with no aftertaste
- Third-party tested for quality and purity
Who should look elsewhere
- Only 60 softgels per bottle, so you’ll reorder monthly
- Higher per-dose cost than bulk options
Reach for this if: you want a certified vegan formula with a proven track record — it’s the crowd favorite for a reason, holding a 4.8-star average across tens of thousands of owners.
Look elsewhere if: you want to stock up for months at a time and don’t mind a non-vegan source.
2. VEV Corefeel Vitamin D3 K2
A 10-month supply in one pouch — 300 softgels of 5,000 IU D3 and 100 mcg K2 MK-7 that swallows easily.
If you hate reordering supplements, this is the pick that ends that cycle. Each pouch holds 300 softgels, which at one per day gives you 10 months of support — that’s five times the count of the 60-count Nordic Naturals bottle above. You get the same 5,000 IU of D3 and 100 mcg of K2 as the Sports Research pick, plus coconut oil in each softgel to help absorption of these fat-soluble vitamins.
Value for money is the second most-praised aspect here, and owners mention the softgels are “not too big or too small,” easy to swallow, and completely tasteless. One owner sums up the experience well: “I’m no longer vitamin D deficient. I appreciate that it has K2. It’s easy to swallow and has no taste.” The formula uses plant-based softgels with no artificial colors or flavors, and it’s produced in GMP-certified facilities.
The honest trade-off is that VEV is a newer brand — it launched in late 2024 — so it doesn’t have the long review history of Sports Research or Nordic Naturals. But with a 4.7-star average across several hundred owners and quality as the top-praised aspect, it’s clearly delivering on its promise for most people.
The bulk advantage
- 300 softgels last 10 months at one per day
- 5,000 IU D3 + 100 mcg K2 MK-7 in each softgel
- Plant-based softgels with coconut oil
Keep in mind
- Newer brand with a shorter track record
- No vegan certification listed on the label
Best for: anyone who wants to set a supplement routine and forget about reordering for nearly a year.
Think twice if: you specifically need a certified vegan D3 source — the brand says plant-based but doesn’t carry the vegan certification.
3. Nordic Naturals Vitamin D3 + K2
A gentler 2,000 IU dose with a pleasant orange essence that makes daily vitamins actually enjoyable.
Some people simply cannot stand swallowing pills, and this pick was made for them. The orange-flavored softgels go down easily, and the brand is famous among families — customers note that even kids and spouses who avoid tablets take these “without hesitation.” At 2,000 IU of D3 and 90 mcg of K2 MK-7 per softgel, it’s a moderate maintenance dose, not a heavy correction dose, which makes it a sensible daily choice.
Effectiveness is what owners praise most here, with many reporting their bloodwork came back normal and their levels held steady. The formula is notably clean: non-GMO, gluten-free, dairy-free, with no artificial colors or flavors, and everything is third-party tested. The K2 is plant-based MK-7, the most bioavailable form, even though the D3 itself is standard (not vegan) cholecalciferol.
The recurring gripe is the price — at 60 softgels, this is a two-month supply at a higher per-dose cost than the 300-count VEV Corefeel, which delivers 2.5 times more D3 per softgel for a similar outlay. You’re paying for the Nordic Naturals reputation for purity and the pleasant orange taste. It falls short of the VEV Corefeel on raw D3 dose — 2,000 IU versus 5,000 IU — but that’s an intentional choice for maintenance over correction.
What stands out
- Orange essence flavor masks any vitamin taste
- Third-party tested for purity and freshness
- Gentle 2,000 IU dose suits daily maintenance
The honest catch
- 60-count bottle means frequent reordering
- Higher cost per dose than bulk options
Pick this when: you or a family member dreads swallowing tablets and needs a pleasant daily vitamin.
skip it if: you need a higher 5,000 IU or 10,000 IU dose to correct a deficiency.
4. Bronson Vitamin K2 MK-7 + D3
When a doctor tells you to raise your vitamin D levels fast, this is the bottle they often point to. Each small tablet packs 10,000 IU of D3 with 120 mcg of K2 as MK-7, the form that promotes enhanced absorption compared to other vitamin K types. The 360-tablet count means a full year of daily dosing in one bottle, which owners repeatedly call excellent value.
Quality is the top-praised aspect, and buyers specifically note the tablets are small enough to swallow easily with no aftertaste and no stomach upset. One owner captures the appeal: “You can get a hefty dose of 10,000 IU in each small capsule, which is wonderful if you are trying to increase your intake and levels. Added advantage is it contains Vit K2 as well!” Several mention their labs came back improved and the dose helped eliminate knee pain.
Bronson has been around since 1960, and the brand leans on that heritage — the tablets are made in a cGMP-registered facility in Hauppauge, New York, and are laboratory tested, GMO-free, gluten-free, and soy-free. The one thing to note is that 10,000 IU is a high dose, so if you’re not deficient, you might find it stronger than you need. Compared with the 5,000 IU picks above, this doubles the D3 per tablet — a deliberate choice for correction, not maintenance.
Why it earns its spot
- 10,000 IU D3 + 120 mcg K2 MK-7 per tablet
- 360 tablets equal a full year of daily use
- Small veggie capsules with no aftertaste
Who it’s not for
- 10,000 IU is too strong for basic maintenance
- Not a vegan D3 source
Pass if: you only need a gentle daily maintenance dose.
5. NatureWise Vegan D3 K2
The NSF-certified vegan formula that swaps coconut oil for organic cold-pressed olive oil.
This pick stands out for a single certification: the contents are NSF-certified, meaning every batch is thoroughly tested for accuracy and purity with no harmful levels of contaminants. That’s a meaningful trust signal if you’re particular about what goes into your body. Each softgel delivers 5,000 IU of vegan D3 from sustainably sourced lichen and 100 mcg of K2 as the clinically studied VitaMK7 form.
Instead of coconut oil, NatureWise uses organic, cold-pressed olive oil that avoids heat and hexanes (a chemical solvent sometimes used in oil extraction) to enhance D3 absorption. Quality and effectiveness are the two most-praised aspects, and buyers describe a clean supplement “with no overpowering odor” that boosts energy without being a substitute for sleep or exercise. One returning customer simply calls it “a really good buy.”
The formula is vegan, non-GMO, and free of wheat, eggs, soy, dairy, tree nuts, peanuts, fish, and shellfish — a strong allergen profile. At 60 softgels, it’s a two-month supply, similar to the Sports Research pick, but the NSF certification and olive oil base give it a distinct identity for buyers who prioritize testing and clean sourcing over bulk value.
The trust factors
- NSF-certified contents for purity and accuracy
- Organic cold-pressed olive oil for absorption
- Vegan D3 from lichen, free of major allergens
The limits
- 60 softgels means monthly reordering
- Higher per-dose cost than bulk bottles
Best for: buyers who want third-party NSF certification and a clean olive-oil base in a vegan formula.
Not ideal if: you’re optimizing purely for lowest cost per dose.
6. NATURELO Vitamin D3 K2
A whole-food capsule that packs wild-harvested lichen D3 and active MK-7 K2 into one plant-based dose.
This is the pick for buyers who want their vitamins to look like food, not chemicals. NATURELO uses whole-food ingredients in a powder-filled capsule rather than an oil softgel, and the D3 is entirely plant-based, sourced from wild-harvested lichen instead of sheep’s wool lanolin. The K2 comes as MK-7, the bioactive form with better bioavailability in humans and well-researched benefits for bone building.
Quality is the most-praised aspect here, and the brand has a loyal following — buyers mention using NATURELO for around a decade and trusting the completely natural, readily available nutrients. Several note the capsule form is easy to take “and does the trick,” with one owner reporting positive results in annual blood work. The formula is made in a GMP-compliant facility and contains no soy, dairy, eggs, fish, nuts, preservatives, or coloring.
The honest caveat is the value debate. The recurring gripe is that this bottle holds just 60 capsules, and some reviewers point out they could get 120 capsules from another brand for around the same outlay. That makes this a premium-priced pick — you’re paying for the whole-food, plant-based sourcing and the trusted brand, not for bulk quantity.
What defines it
- Wild-harvested lichen D3, fully plant-based
- Whole-food powder capsule, not an oil softgel
- Active MK-7 K2 with well-researched benefits
Weigh this
- 60 capsules is a short supply
- Higher per-dose cost than bulk alternatives
Reach for this if: you prefer whole-food powder capsules and want a loyal, long-established plant-based brand.
Skip if: you’re shopping for the lowest cost per dose.
7. aSquared Nutrition D3 K2 Chewable
A cherry-flavored chewable with 180 tablets — for anyone who simply won’t swallow a pill.
Swallowing is the single biggest barrier to taking supplements daily, and this pick removes it entirely. These are chewable, cherry-flavored tablets you actually want to eat — taste is the most-praised aspect here by a wide margin, with one owner noting they taste so good you’d never confuse them with a bitter pill. Each tablet carries 2,000 IU of D3 and 75 mcg of K2 as MK-7.
Beyond the flavor, the 180-tablet count is a real advantage: that’s a 180-day supply at one tablet per day, or 90 days if you take two. Your body absorbs chewables quickly, and the formula supports bone density, calcium absorption, healthy teeth, and cardiovascular and immune health. Shoppers say their doctors were happy with lab results, and the tablets are easy on the stomach.
The trade-off is the K2 dose — at 75 mcg per tablet, it’s lower than the 100 mcg in the Sports Research or VEV picks above, and the 2,000 IU D3 is a maintenance dose rather than a correction dose. It’s made in the USA in a GMP-certified facility and is non-GMO. If you’re comparing strictly on potency per tablet, the Bronson pick delivers far more D3, but this wins on the experience of actually taking it.
Why it’s a favorite
- Cherry-flavored chewable — no swallowing needed
- 180 tablets for a 180-day supply at one a day
- Quick absorption through chewing
The trade-off
- 75 mcg K2 is lower than other picks
- 2,000 IU D3 suits maintenance, not correction
Choose this if: you or someone in your home refuses to swallow capsules and needs a genuinely pleasant daily tablet.
Pass if: you need a higher 5,000 IU D3 dose.
8. BioEmblem Vitamin D3 K2 Capsules
The only pick here that gives you both K2 forms — fast-acting MK-4 and long-lasting MK-7 — in one capsule.
If you want the complete K2 picture, this is the formula built for you. Each capsule contains 5,000 IU of D3, plus 100 mcg of K2 MK-7 and 100 mcg of K2 MK-4 — a 200 mcg total that uses two different K2 forms for different timing. MK-4 absorbs quickly, while MK-7 stays active in your body much longer. The MK-7 is the patented MenaQ7, a clinically studied form derived from chickpeas.
Effectiveness is what owners praise most, with several reporting their D3 levels are no longer deficient “for the first time in decades.” The capsules are vegetarian, non-GMO, and contain no soy, gluten, shellfish, artificial binders, fillers, or preservatives — just veggie capsules and rice hull extract. Every batch is tested four times during production for purity, and the formula is made in a GMP-certified US facility.
The D3 in cholecalciferol form is the same form your body gets from the sun, so it’s ready to absorb right away. Compared to the VEV Corefeel’s single-form K2, this adds the fast-acting MK-4 layer for a more complete approach, though the 90-capsule count means you’ll reorder sooner than the 300-count bulk options. Buyers also note it pairs well with magnesium for broader support.
The standout features
- Both MK-7 and MK-4 forms of K2 in one capsule
- Patented MenaQ7 — clinically studied MK-7
- Tested four times per batch for purity
What to note
- 90 capsules is a shorter supply than bulk picks
- Higher K2 dose may be more than some need
Pick this if: you want the most complete K2 coverage with both fast and long-acting forms.
Skip if: you prefer a simpler single-K2 formula.
9. NatureBell Vitamin Double Strength D3 + K2
A double-strength 10,000 IU softgel with 200 mcg K2 — high potency plus an 8-month supply.
This is the pick for anyone who wants maximum potency without constant reordering. Each softgel combines 10,000 IU of D3 as cholecalciferol — the same form found in the sun — with 200 mcg of K2 as menaquinone 7. The 240-count bottle delivers an 8-month supply at one softgel per day, making it one of the strongest value-per-dose options on this list.
The formula is third-party tested and free of gluten, dairy, soy, and eggs — a clean allergen profile at high potency. One thing to note: at 10,000 IU of D3 and 200 mcg of K2, this is a genuinely strong dose, so it suits correction or higher-need situations rather than casual maintenance. It beats the Bronson pick on K2 — 200 mcg versus 120 mcg — while matching the 10,000 IU D3 count.
The strengths
- 10,000 IU D3 + 200 mcg K2 MK-7 per softgel
- 240 softgels for an 8-month supply
- Coconut oil infusion for better absorption
Consider this
- Very high dose best for correction, not maintenance
- K2 comes only as MK-7, no MK-4
Best for: those with a confirmed deficiency who want a high-potency dose and a long-lasting bottle.
Not for: casual users who just need a small daily maintenance dose.
Understanding the Specs
Vitamin D3 Dose in IU
IU stands for International Units, the standard way vitamin potency is measured. A 2,000 IU dose is a gentle daily maintenance level, while 5,000 IU is a common correction dose and 10,000 IU is a high-potency dose usually taken under a doctor’s guidance. The right level depends on your sun exposure and blood test results, not on picking the biggest number.
Vitamin K2 as MK-7 and MK-4
K2 comes in two main forms. MK-7 stays active in your body much longer and is the most-studied form for bone support, which is why most picks use it. MK-4 absorbs quickly but doesn’t last as long. Some premium formulas include both so you get fast action and long-lasting coverage in one capsule.
Vegan D3 vs. standard D3
Standard D3 comes from lanolin, a natural oil in sheep’s wool. Vegan D3 is sourced from lichen, a type of algae that produces the same bioavailable vitamin. Both work identically in your body, but if you follow a plant-based diet, look for “vegan,” “lichen,” or “VegaDelight” on the label.
Carrier oils and absorption
D3 and K2 are fat-soluble vitamins, meaning your body needs dietary fat to absorb them well. Many softgels include a carrier oil — coconut MCT oil or organic olive oil — so you don’t have to time your supplement with a fatty meal. If a product has no carrier oil, take it with food for best results.
