I started with a vitamin D level of 24.3 and after taking this specific supplement for 4.5 months (one pill every 2 days) I reached 10.2 in the last measurement. I won't go near it again. You get what you pay for.

Very good, very economical and advantageous. The results will show in the next blood tests. There is a sediment inside the package that impressed me. It's as if the pills are dissolving inside the box. Very small capsule and correct. No side effects, with the K2 which is necessary as a supplementary vitamin for proper absorption, and of course vegan.

I have been buying it for years mainly for my daughter who has a vitamin D deficiency. In blood tests, she is now within normal limits.

We have reached normal levels for the whole family! Even my father, who had a significant deficiency, reached normal levels after three months with this product

Ideal amount for good vitamin D in the winter and with the necessary dose of K2 (in proportion to D3) for calcium absorption from the bones.
I took two tablets a day for three weeks to boost my D and now I take one every day. I feel with tremendous energy like in the summer when I go to the sea and the sun sees me for hours. It is worth taking D in the winter especially if you are deficient, which 40% of adults are.

I have the impression that it does what it says, I take them for a while, but the point is that they are vitamins and they do good!

Simply perfect. Without many words. And affordable. I recommend it without a second thought. Stay away from Youcurse.com.
