Vitamin D has always been known as an anti-rickets vitamin. In recent years, however, its enormous importance has been discovered as a powerful regulator of the immune system.
It is very common to find people in whom the blood level of vitamin D is low or even seriously lacking.
This evidence is a direct consequence of a missed, or reduced, exposure to sunlight. This is because the sun’s UV rays promote the synthesis of vitamin D at the epidermal level.
In healthy people, vitamin D deficiency is an important risk factor for many pathological conditions, such as hypertension, type 2 diabetes, vascular diseases, autoimmune diseases and many types of cancer. In people who are already ill, it is often necessary to use high doses of this vitamin. This use, however, must be followed closely, preferably by an expert doctor, as it could lead to serious side effects on the renal system as well.
However, if you observe certain rules, and undergo periodic checks, you can take a high dose of vitamin D safely. Today the scientific literature is increasingly dealing with the use of vitamin D in all autoimmune diseases (eg Parkinson’s disease, Psoriasis, Crohn’s disease, etc …), as well as in other diseases such as migraine, autistic syndrome and Alzheimer’s disease.
Finally, there are very important correlations between vitamin D deficiency and oncological degenerative diseases, such as breast, colon, prostate and lung cancer.
