WHAT IT DOES

Three jobs, one softgel

Sunlight makes vitamin D in the skin. Above the 37th parallel, half the year does not have enough of it.

  • Bones and immunity

    D3 helps the body absorb calcium and supports normal immune function. K2 as MK-7 helps that calcium go to bones.*

  • Winter-proof

    One softgel with breakfast from the first cold morning to the first warm one, and you do not think about vitamin D again.

  • Absorbed with fat

    D3 and K2 are fat-soluble, so the softgel carries them in coconut oil and omega-3 rather than a dry tablet.

A Lot Packed Into A Little Pill

These softgels are surprisingly tiny. My other vitamin D3 pills are also tiny, but I've found that magnesium glycinate tends to need a larger pill, so these were a surprise. I'm pleased that these pills contain the superior form of magnesium in the form of magnesium glycinate, and that it is clearly labeled how much elemental magnesium you are receiving per pill. You also get an impressive 500 mcg of K2 per 10,000 IU of D3. Many other supplements offer only around 100 mcg K2 for this amount of D3, and I've personally needed to add extra K2 on the side, but for these it's not necessary. You get a lot in one small pill, cutting down on buying supplements separately. Very pleased with this order.

I’ve been dealing with depression and bought another brand of vitamin D and it made me sick. I learned most brands of vitamin D are extracted from Sheep wool and are heavily processed. I did some research and found Puretrex came highly rated. After a few days of taking Puretrex vitamin D I felt like sunshine entered my life again. Over the last few weeks my depression is lifting. Please, if you’re struggling, try Puretrex.

Just what I was looking for in a D3 supplement

I’ve been taking this daily and overall I’m pretty happy with it. I especially like that it’s UK made so it gives me more confidence in the ingredients and manufacturing process, which isn’t always obvious with supplements these days. The high strength plant-based D3 plus K2 combo feels like a solid foundation for my daily wellness routine and fits nicely into my morning ritual. The capsules are quite small and tasteless so they are easy to take.I also appreciate the added omega-3 DHA/EPA, astaxanthin, and black seed oil since they add some extra nutrient support beyond just the basics. In terms of value, it's an excellent value since the dosage is 1 per day and this has 180 or six months supply.That said I’m holding back a star only because it isn’t some buzz-worthy miracle and results are subtle over time. If you’re looking for solid, steady support and like the idea of a carefully made UK supplement, this one delivers and feels like a reliable daily partner.

The soft gels are smooth and easy to swallow, making daily use convenient. So far, I haven’t experienced any allergic reactions, and overall, it feels like a reliable and effective way to maintain healthy vitamin D levels.

Excellent D/K Supplement With Extras!

These softgels by Puretrex are a high potency D3/K2 supplement that contains organic coconut oil, black seed oil, magnesium glyconate, omega 3s, astaxanthin and black pepper for better absorption. They are vegan and manufactured in the U.K. They are tiny and easy to swallow and they didn't give me any digestive issues. No smell. No aftertaste.I have low Vitamin D in general, so the bigger dosage saves me from having to take several smaller capsules. After 3 weeks of switching from my normal supplement to these, I have not noticed any drop in energy or mood, so I feel these are working well for me. These are high quality and priced super affordably, with 180 doses in the pouch - and they weren't all stuck together! Very impressed with these softgels and will continue to order.

Best D3+K2 I’ve ever taken, hands down

I’ve been popping one of these Puretrex D3+K2 softgels every morning for about 10 days now and I’m already noticing a huge difference. My mood is noticeably sunnier (perfect timing with the shorter winter days), my energy feels stronger and more even, and that random achy feeling I used to get in my legs and back on cold mornings is basically gone.What I love most:10,000 IU D3 + 500 mcg K2 is a serious, therapeutic dose, but because it’s paired perfectly with the K2 (real MK-7), I have zero worries about calcium going to the wrong places.The added coconut oil, magnesium, omega-3s, and astaxanthin make these feel like a mini “immune & bone insurance” pill instead of just plain D3.100% vegan, tiny, and super easy to swallow, no fishy burps, no aftertaste.180 softgels = 6-month supply at one-a-day, insane value.I got my blood levels tested right before starting and I’m getting re-tested in a few weeks; I’m betting my D is going to be in the sweet spot for the first time in years. If you live somewhere with weak winter sun or just want the absolute best D3+K2 combo on the market, stop scrolling and grab these. Already planning to never run out!

Very small, easy to swallow.

Very small gel caps, and I only need to take one to get a pretty potent dose of vitamin D. I was a little concerned that they are packaged in a ziplock pouch, but there were no issues with crushing or rupturing the contents. The label states that they are distributed by a US company but did not list the manufacturer origin.

Easy to swallow softgels that are simple for daily use

These vitamin D3 + K2 softgels are easy to take and honestly pretty simple to fit into my routine. The gel capsules are small and smooth, so they go down without that weird chalky feeling some supplements have. There’s no strong taste or aftertaste, which I really appreciate because I hate when vitamins linger in my mouth. The bottle is sturdy and the lid snaps tight, so it doesn’t spill when I toss it into my backpack.I like that the softgels don’t stick together and are easy to grab, even on rushed mornings before school. They’re also lightweight enough that I can keep a few in a small pill case when I’m staying overnight somewhere. Only small trade-off is that the capsules are pretty glossy, so if your hands are wet they can slip a bit, but wiping them off fixes that fast.If you want a supplement that’s simple to swallow and easy to keep on hand, these softgels are a chill option.

Great immunity support

I was looking for a combination of D3 and K2 for immunity support and found these gel caps. These looked great since they include a comprehensive list of other supplements for bone and heart health, also they support energy and vitality. I'm going to be a little cautious since I've never taken a supplement with astaxanthin in it, I'd research it to make sure you aren't surprised if you get any side effects. The soft gels are easy to take. I not a big fan of the sealable pouch they come in. I prefer bottles since they are easier to store.

Better immune system, stronger nails and improved mood

These capsules are small, easy to take. They were easy to add to my supplement routine. They don’t have a distinct smell or aftertaste. Their vit D content is impressive. They’ve been helping me with my immune system and my mood in the fall season. I also think that they improved my nails a little bit. Overall I’m very happy with this product.

PURETREX Vitamin D3 10,000 IU + K2 MK-7

These small easy to swallow D3 and K2 gelatin pearls are a very high quality in my opinion. I liked their manufactured in the UK, and that they have a slight coconut taste to them. I've only been taking them for a few days now, but I feel that they are personally beneficial to me and my health. I like that you only have to take one a day so this should last me 180 days which makes this a good value for the money in my opinion.

Great supplement combo

Ordered as a new version of D3+K2. Arrived promptly in a vacuum sealed bag. Vitamins are small gel caps, easy to swallow with no bitter aftertaste. This product includes 180 vitamins, at 1 per day for a total of 6 months - which is great, especially considering the low price point. As this vitamin combo is arguably a necessity for people to maintain health and energy levels, this is an easy one to recommend.

Nice small way to take

This is great. I actually feel this is perfect size or small enough to take every day and you only need to take one vitamin D3 is so important so that I can absorb the calcium, especially since I am physically active and I like the benefit of the K2 as well, so I’m very happy that this was easy to find and I can get both supplements in one. It also has other ingredients like a mega three fatty acid, which is great, especially since I’m trying to maintain a healthier cholesterol and healthy heart so it definitely is very beneficial for me and the magnesium is also a benefit definitely with cramping in my legs, but vitamin D3 I’ve been needing especially for the absorption of calcium so this is perfect. The capsule or small easy to swallow. I take it with food every morning and it doesn’t upset my stomach or irritate me at all.

Not Sure How I Feel About These

I ordered this thinking I was getting just vitamin D3 and K2- totally my fault for not paying attention. There are lots of other things in this as well- black seed oil, magnesium, omega 3, and something called astaxanthin that I had never even heard of before. I did some quick research on the last one- very interesting! I am not a doctor and have no qualifications at all to recommend any supplements to anyone- I feel we all need to do our on investigating or consult with our doctors to make the best decisions that we can. With that in mind, I always limit my comments on the supplements that I try. These pills are double the size of the D3 pills I normally take but they are still very small and easy to swallow. I have taken them for a few days and they don't bother my stomach or cause any issues. These are currently priced at $40. I do find the formulation to be a very interesting combination. I know I need the D3 and the K2 for sure as it was recommended to me by my doctor. I am going to keep taking them and see how I feel. I do a lot of different things for my health so it's hard to pinpoint what is making the difference at times. I like what I am reading so I do find this to have some interesting potential.

Good supplement—high dosage of D3

I’m impressed with these soft gels overall. After doing some homework I appreciate the transparency from Puretrex regarding their testing and ingredient purity. These D3 and K2 supplements are manufactured in the UK, non-gmo, with limited ingredients. These also contain moderate amounts of omega 3 and magnesium glycinate. The D3 dosage is high—really at the limit of what is considered healthy for an average adult (10,000 IU). That said, I think this already generous supply of 180 will last longer because I don’t intend to take them more frequently than every other day, and not on an empty stomach. Thankfully they have a great expiration date!

DIRECTIONS

Simple enough to stick

Vitamin D3 + K2 routine
  • 1 1 softgel with a meal

    The meal with the most fat, usually dinner.

  • 2 Every day through winter

    From the first cold morning to the first warm one. Sun does the job in summer.

  • 3 Every other day for a lower dose

    One softgel every second day halves the dose, and the pouch lasts a year.

SUITABILITY

Made for your routine

Who Vitamin D3 + K2 is for

Great fit if you

  • Have been told your vitamin D is low, or live somewhere with a real winter
  • Are vegan or vegetarian and found that most D3 comes from sheep's wool
  • Take a high-strength D3 on a doctor's advice and want K2 with it

Not for you if you

  • Are pregnant, breastfeeding or buying for a child. This dose is not formulated for you.
  • Take a blood thinner. Vitamin K interacts with warfarin and similar medicines, so talk to your doctor first.
  • Already take another vitamin D product or a multivitamin with D. Add them up before you add this.

QUESTIONS

Before you order

Is 10,000 IU too much?

It is a high dose and a fair question. The National Institutes of Health sets a Tolerable Upper Intake Level of 4,000 IU a day for adults and notes that signs of toxicity are unlikely below 10,000 IU a day. Plenty of people take 10,000 IU on a doctor's advice after testing low; plenty do fine on less. The honest answer depends on your blood level, and a test is the only way to know. For a lower dose, take one softgel every other day.

Why is the D3 from lichen?

Almost all vitamin D3 is made from lanolin, which comes from sheep's wool. Lichen-derived D3 is what makes this suitable for vegans.

Can I take it with a multivitamin that has vitamin D?

Yes, but add the two up. Most multivitamins carry 400 to 1,000 IU. If in doubt, take this one every other day so the total stays where your doctor wants it.

Drops or softgels?

The drops are a different strength and format. The softgel is easier if you want one thing to swallow and forget.
