I am definitely satisfied with the product, which I have been taking for a few months now (and I intend to continue, under the supervision of my nutrologist). The main purpose behind my purchase and use was its ability to prevent and reverse hair loss, which is believed to be associated (along with several other factors, of course) with calcification in the region of the scalp, which miniaturizes and prevents growth healthy hair strands on the head. It is recommended that it be consumed along with vitamin D3, which potentiates the effects of them. Many people do not know much about vitamin K2, which is essential for our body and is water soluble (it needs fats, lipids, to be absorbed when we ingest it). Among its many functions, vitamin K2 is able to combat various problems, such as heart disease, osteoporosis and hair loss, as I mentioned. I recommend that the reader do a research and read more about its features, as well as consult your doctor when you consume. Without a doubt, it is a product that I would recommend.
