Gastroenterologist and nutritionist Yana Prudnikova told how SPF cream affects the body's absorption of vitamin D. Many people think that it prevents its formation.
Vitamin D can enter our body in various ways and ways: with food, bioactive supplements, and also through the skin under the influence of the sun.
“In fact, it does not matter at all how it comes, since vitamin D is initially inactive and must undergo two hydroxylations for absorption and assimilation. SPF creams do not interfere with the absorption of vitamin D by the skin, ”says the expert.
How to take vitamin D correctly so that it is better absorbed by the body? The best time is morning or at least the first half of the day. In the evening, vitamin D can cause insomnia by affecting the production of melatonin, the sleep hormone.
For better absorption, take vitamin D along with fats, magnesium and boron. Supplemental magnesium is especially important if you are taking vitamin D at 5,000 IU and above. You can use magnesium bath salt, for example.
If there are problems with the joints, you need to take vitamin D along with K2. The optimal form of vitamin D is liquid (you can use capsules or spray), for children it is water-based.
