Who is K2 + D3 for?

K2 + D3 is for anyone looking to support strong bones, a healthy heart, and their everyday immune health.

How do I know if K2 + D3 is right for me?

K2 + D3 might be a good fit if you:

• May have lower than optimal Vitamin D levels

• Want extra support for bone and heart health as you age

• Spend limited time in the sun or live in a low-sunlight climate

• Are a post-menopausal woman looking to maintain bone density

• Are focused on keeping your immune system strong year-round

When should I take K2 + D3?

For best absorption, take one capsule in the morning with a meal that contains healthy fats.

How long before I start noticing results?

Early benefits like less bloating or smoother digestion may show up fast, but deeper gut and immune balance happens over 60–90 days. That’s the timeline for your microbiome and cells to reset effectively.

How can I be sure K2 + D3 is high-quality and safe?

At Bioligent, our products undergo rigorous testing through trusted third-party labs to meet our high standards for safety and quality. We always make sure to test for: 

Ingredient Integrity: We verify that the amount and potency of each ingredient listed on our labels are accurate.

Heavy Metals: We screen for harmful contaminants including lead, mercury, and other toxic metals.

Product Purity: We check for potential impurities like E. Coli, yeast, and mold, and certify that our ingredients are gluten-free, dairy-free, organic, if applicable, and non-GMO before going into production. 

Glyphosates: We ensure that our products are free from harmful pesticides.

I’ve spent a lifetime trying to find solutions for several health issues — asthma, depression, migraines, hormonal imbalances, you name it. So, I opened a private practice specializing in neuroscience and neuronutrition to improve lives through nutritional and natural ways of healing.

But over the last 30+ years, new stressors and environmental toxins have harmed my patients’ health — and it’s been increasingly difficult to find trustworthy formulas that meet their needs. 

Bioligent was the obvious next step. Here, we create natural supplements with intentional, clean-sourced ingredients, backed by science you can trust — giving you the power to combat oxidative stress and overcome your body’s innate limitations.

Bioligent Vitamin D3 + K2 Supplement – Review

I call this my “sunshine in a capsule.” I live a pretty active lifestyle — gym, classes, studying — but there are days when I realize I’ve been inside for 14 hours straight, surviving on LED light and caffeine. That’s when this Bioligent D3 + K2 combo steps in.Each capsule packs 5000 IU of D3, which is perfect if you’re like me and your main source of sunlight is your laptop screen. The K2 is a solid addition too — it helps your body actually use the Vitamin D properly, kind of like the wingman that makes sure your bones and heart stay in sync.They’re small, easy to swallow, and vegan-friendly (no weird gel caps or fishy taste). I started noticing better energy after a week — not the “I just drank a Red Bull” kind, but the steady, “I don’t need a nap at 2 PM” kind. My mood’s been noticeably lighter too, which I’ll gladly take during those gray, assignment-heavy days.Funny story — one morning my roommate caught me taking these and said, “Bro, you look like you’re prepping for hibernation.” I said, “Nah, I’m just stockpiling sunshine.” He laughed, then asked where to buy some.If you’re trying to keep your immune system, bones, and sanity in check while living the college grind, this supplement’s a low-effort win.⭐ Rating: 5/5✅ Great for daily energy and mood✅ Easy-to-swallow vegan capsules✅ Ideal for indoor-dwelling gym bros and students alike✅ Clean formula — no GMO, gluten, or junk fillers💡 Verdict: Feels like bottled sunlight for people who forget what the outdoors looks like.

Just one capsule per day instead of two.

Between work, kid activities, and everything else, I rarely remember more than one supplement a day, so a clean, plant-based capsule made sense. These capsules feel well made (non-GMO, third-party tested) and I like that they emphasize daily routine rather than flashy promises. These capsules are easy for me to swallow. After a month, I felt a slight boost in energy, though I can’t say it’s night-and-day. The cost is higher than generic vitamins, but for someone who doesn’t want to waste time with multiple bottles, it’s convenient. My only frustration: for the price I’d hoped for more noticeable impact but sometimes consistency is the win. Overall: a good value for a busy mom who wants to stay on top of wellness.

D3 combined with K2 reduces the number of supplements to swallow!

I’ve been taking vitamin D for several years, as recommended by my doctor since my levels tend to run low. A few years ago, I switched to D3 after learning that it’s more easily absorbed by the body. More recently, I learned about the benefits of adding K2 for better absorption and additional support. Enter this product, Bioligent D3 K2 Supplement.I’ve been taking it for a couple of weeks now. I haven’t noticed any big changes yet, but I didn’t really expect to since I was already using D3. I’m hopeful I’ll see good results at my next blood test.I appreciate that this supplement is a "clean" product, and the expiration date (2027) is clearly printed. The capsules are standard-sized, easy to swallow, and leave no strange aftertaste. I'm also using another supplement from Bioligent and have been very happy with it, so I’m expecting positive results from this one too.

A Good K2 and D3 Paired Supplement for Immune and Bone Function

This supplement helps direct calcium to bones while avoiding accumulation in soft tissues by combining vitamin K2 (MK-7) and vitamin D3 (5000 IU). Combining D3 with K2 has been shown to improve calcium absorption and utilization, supporting immunological, cardiac, and bone health. Daily use is easy and efficient with the one-a-day capsule.Because the product is non-GMO, vegan, gluten-free, and third-party tested, its efficacy and purity are guaranteed. The business's formulation strategy, which is based on research, lends it even more legitimacy. All things considered, this is a decent D3/K2 supplement that provides good value for ongoing wellness support. My only complaint is that the amount of K2 (as MK-7) is 100mcg, which is only 83% of the recommended daily value of this vitamin. Although the vitamin is fat-soluble, and thereby stored in the body for later, I still personally prefer my vitamins to contain at least 100% recommended daily value of each vitamin, to prevent me from having to supplement from other sources, which can ultimately become overly complicated.

2 in 1 D3 & K2 and only once a day. Yay

This review is being written on October 24th 2025 in case of future updates.The first aspect I would like to point out is that these come with an expiration date of 2027. This gives you a full 2 years to use the supplement without having to worry about them going bad if you're not taking them everyday.The pill is wide and about the width of a penny. For me it was very easy to swallow. With some vitamins or supplements it might give you reflux or a weird aftertaste but not with these. I did not experience any upset stomach or reflux. This leads me to believe that they are using quality ingredients.Not only does this have D3 but it has K2 and to my understanding both are needed so your body can absorb it better. This makes it easier instead of having to take two different vitamins or supplements by having two in one.There is no weird smell or aftertaste. It really doesn't taste like anything which is nice.another benefit to these capsules is that it is only one capsule a day. There are too many supplements of vitamins where you have to take two or three a day and who really has time for that? They also come in a dark tinted bottle to preserve their freshness and the capsules themselves as you see in the photos are dark. I feel like that provides double the protection to ensuring that the ingredients inside are protected and kept fresh.Just like with any vitamin or supplement you do need to take it for quite a while to feel their effects so I can say how much of a difference it has made at the moment. But at the same time I feel like you can go wrong because for the most part many people tend to be vitamin d deficient because we are just not outside enough to absorb enough vitamin d that our bodies require.So for the time being I do think this is a great product because it does include K2 with a D3. That the company made it easier by only making it one capsule a day. That the ingredients do not cause reflux or weird aftertaste. And that buy using a dark bottle and dark capsules they are preserving the freshness of the ingredients. Overall, I'm very happy with the product.

🦴 ☀️ Great For Lack of Sunlight and Bone Health

One of the drawbacks of living in a northern climate is that you'll lose sunlight for a few months of the year in which it's best to supplement vitamin d with external sources such as this product.While this is someone on the pricey side, the added benefit is that this isn't just vitamin d but also comes included with K2, which if you're an older individual can help with bone and heart support, which is good for you have any osteoporosis symptoms or at risk.I will note a word of caution for anybody that's interested in this product that the added K2 can thicken your blood. So do keep that in mind if you have any issues with blood clots. As per usual you'll want to console your doctor, but as far as how well this product has been, it's been great!I feel good after taking it throughout the day and my mood is regulated and stabilized. So I feel the effectiveness of this throughout the day and throughout my week as I've been taking it.I've made sure to include photos of how large these pills are, so if you're someone who doesn't like taking large pills, this may be an aversion.

Convenient to take

I take vitamin D3 and vitamin K2 every day. The supplements I had been taking prior to this was three capsules a day to get the right amount of both vitamins. This is way more convenient. I just take one capsule and that gives me both vitamin D3 and K2. The simplifies my supplement intake. I really like that this is made in the USA. I also appreciate that I recognize all of the ingredients. I’ve used this brand of supplement before and it’s always been good. I’m happy to reduce the number of capsules I need to take so this is a win. Five out of five stars.

Thumb’s up!

I really like this brand. It’s the second time I’ve ordered from this company.Following my doctor’s orders, I began taking Vitamin D3. After doing some reading, I decided that K2 was beneficial for my body too. I now try to buy both vitamins in a combination, like in this product.Although I am new to this product, it seems to be doing the job. Frankly, I haven’t noticed any changes from the last brand of D3/K2 that I was taking, but I guess that’s good. I take it to protect my body.Above all, what I really look for in a supplement is a product I can trust, that is tested and is what it says it is. I feel that this brand fits that bill.I still wish this supplement company and others were more transparent with exactly where their ingredients come from and what standards of testing a product has gone though, but for now I see that it is better than a lot of other brands out there. Safety is a priority for me.It’s always important to ask your doctor about supplements to make sure they are right for your body, because we are all different.As a side note, I like the glass bottle instead of plastic. It not only feels better in my hands, but I’d like to think it’s better for the environment too.

Excellent D3 + K2 Combo.

This D3 + K2 supplement has been a great addition to my daily routine. I really like that each capsule delivers a high-potency 5000 IU of D3 paired with MK7 K2, which helps ensure calcium goes where it should to my bones and teeth instead of building up elsewhere. I’ve felt a noticeable difference in my overall energy and immune support, especially during seasonal changes.The capsules are small and easy to swallow, making it simple to stick to a consistent daily dose. I also appreciate the clean ingredient list vegan, non GMO, gluten free, and free of artificial additives. It gives me confidence that I’m taking a quality product.Knowing it’s formulated by a women-led, science-driven team adds another layer of trust for me. Overall, this is a well made, effective supplement that supports bone, immune, and heart health. Highly recommend for anyone looking to keep their D3 and K2 levels steady year round.

Vegan D3 K2 5000 IU for Bone and Immune Support

I started taking this D3 and K2 combination to address my historically low Vitamin D levels, especially during the winter months, and I truly appreciate the thoughtful vegan and clean-ingredient formulation. The fact that it combines D3 with K2 (MK7) makes me feel more confident that the calcium is being utilized correctly for bone strength, rather than just circulating in my system. It’s an easy-to-swallow capsule that I take with my first meal, and I’ve felt a noticeable improvement in my overall mood and well-being since making it a consistent part of my daily health foundation.
