Vitamin D3 is one of the most deficient elements in the population (after iron and magnesium) And at the same time, it is one of the most studied vitamins by scientists. Hundreds and thousands of articles have been written about its effect on the body (both deficits and excesses). There are many reasons for its lack - smog over cities, a small number of hours in the sun, poor functioning of the gallbladder and intestines, genetic disorders, etc. A lot has been written about its effect on the body and signs of deficiency and dosages even here in the reviews. I will not repeat myself. I will write about the important nuances of the reception. 1) If you have anemia and D3 deficiency, then taking D3 should start with small doses. Since one of its qualities is the improvement of the trophic tissues. The nutrition will improve, but there is nothing to feed the tissues, there is no oxygen. As a result, there may be dizziness, weakness, etc. 2) Elderly people who have a poorly functioning gastrointestinal tract and people who have undergone surgery on the gastrointestinal tract should give preference to sublingual forms, which would certainly be absorbed. 3) If you are breastfeeding and taking vitamin D3 separately from multivitamins, according to tests you have a level of at least 70 ng / ml, then we give the baby a dose slightly lower than the preventive 4) If you have metabolic disorders or obesity, we increase the required official dose (both preventive and therapeutic) by almost 2 times 5) The main factors of vitamin D and its proper distribution in the body are not only K2, but also magnesium and vitamin A (it is an antagonist-synergist) Their necessary level is very important, so that sand is not deposited in the kidneys and so on. As for this particular jar, it raises the level of vitamin D3 very well according to the tests. Useful? Press the thumbs up.
