An important supplement!
A lack of vitamin D can lead to insomnia, depression, muscle pain, headaches, depression, heart disease, and this is not the entire list. Vitamin of this brand took on the recommendation of a doctor, because the test results showed that I have a very low level of vitamin D. Therefore, the doctor first prescribed a dosage of 10,000 IU, after three months of taking and re-testing, the doctor changed the dosage to 5,000 IU, because The level of vitamin D has risen enough and now it needs only to be maintained. I want to note that experts equate vitamin D to the hormone, it is important and necessary for everyone and even those who live in sunny countries. And on an ongoing basis, and not only in the fall and winter. To determine the dosage I recommend to consult a doctor, it must be properly selected. And with the dosage you need to be careful, because Vitamin D can produce kidney stones.
