Vitamin D: what happens when it is low, watch out for chronic fatigue

Vitamin D is a hormone that is produced when we expose ourselves to sunlight (UVB rays). Small quantities can be consumed in the diet, for example by consuming salmon, oily fish, eggs, milk and dairy products and some types of meat (such as pork and beef liver). This vitamin ensures the intestinal absorption of calcium and phosphorus, which play a key role in the health of joints, muscles, teeth and bones (preventing osteoporosis). People with low levels of vitamin D need to supplement it with supplements. Any deficiency is measured through a simple blood test and it is then the family doctor (or an endocrinologist specialist) who establishes the therapy, if necessary. It is very important to measure vitamin D levels in pregnant women, to prevent fragility fractures during pregnancy or breastfeeding.
