In a test 3 months ago, the D level was 8 ng/mL. With daily intake for 90 days, its level rose to 44 ng/mL (with total calcium 9 mg/dL). No side effects. Worth its money

In a repeat test after 20 days of taking this supplement, my D3 levels went from deficient to sufficient. So for me, it worked quite well and quickly.

So far I haven't found anything more high-quality on this platform.
- Few, simple, and very clean ingredients.
- K2 in MK7 form (the best).
- D3 amount 4000 iu which is the appropriate one.
- A little magnesium to activate the D3 as it should.
Price is a bit high but obviously you get what you pay for and when it comes to a quality supplement for our health, the money is not wasted.

The best! From 11 to 37 in 1.5 months. The combination of D3 with magnesium makes a difference in absorption.

I have tried various brands for D3. I had also taken another D3+K2 from two different bottles of a good brand and it increased a bit more, but until then, when I was only taking D3, it was increasing slowly. With this brand, it finally increased and quickly after 7 years of treatment above the limit... I was at 13 and in 6 years I went to 24 with K2. With this, in 2 months, 32!!! Bravo!!! Expensive, but it works!!!!

immune system boost, which I never imagined. I will never stop it. As for bones, I have no opinion, maybe as I grow older

It is an effective supplement. My wife started it due to a deficiency because her vitamin D was 8 ng/ml in the blood tests. She started the supplement on 02/27 and on 04/03 (5 weeks later) when she tested again, it had increased to 24.4 ng/ml.

Although I had done extensive research and concluded that its composition was the most "correct," I was hesitant due to its price. I started it at the end of January with 16 and now at the end of March, I have reached 34. In 2 months, it took me from a severe deficiency to sufficiency. I will continue it for another month daily and then I will reduce to every other day. I will check again in 3-4 months

This supplement is really worth the money; even though it costs almost €40, it does what it says. For the 4 months that I've been using it, I've noticed various improvements in my mood, and I feel my bones much more rested and stronger overall. If you're looking for a vitamin D supplement, this is definitely worth it. However, for someone who doesn't want to spend that much money on a supplement, I wouldn't recommend it, especially if you're not that interested in vitamin D. But if you have a significant deficiency in vitamin D, it's worth spending the money. Of course, it's good to get tested and consult a doctor to be sure. Personally, it has helped me a lot, and this is the third time I've ordered it!!!

It really does what it promises. I do a carnivore diet and while I get all the vitamins from meat and eggs, D3 is hard to obtain from food, and the tests I did showed very good levels!
It also has the necessary K2 for absorption and to prevent calcium from accumulating in the arteries, as well as the very useful magnesium.
I take them in the afternoon when the sun has set along with my meal; it requires a fatty meal for good absorption.
I highly recommend it

I was skeptical but it really works! Within 2 weeks my mood changed (I had very low D), I sleep better and wake up refreshed. I will buy it again

I take it at night just before bed. I think from the first week I started sleeping better, in the next blood tests I will find out if my D levels have increased.

The best company for supplements! From the very first week of using this one, the intense muscle pains stopped and my mood improved, as if I were taking an antidepressant. The price may scare you, but once you see the benefits, it will no longer concern you

It will show in the next exams.
update:
Within 4 months, vitamin D increased from 26 to 120. 2 times a day in combination with the drinkable vitamin. Excellent quality. It's worth its money.

The most high-quality, pure, and easily absorbed vitamin available, maybe even internationally. It's worth every euro and its results are immediate! Don't settle for anything cheaper. There is nothing superior in its category.
