Vitamin D, A Miracle Vitamin?
Good for bones, for the heart, fighting properties against cancer and cardiovascular disease, vitamin D is presented as a miracle cure. The problem is millions of us are deficient in vitamin D. What are the risks of vitamin D deficiency? How not to be deficient in vitamin D? What is the best vitamin D supplement?
Nearly 80% of the French population is deficient in vitamin D. This is why it’s often prescribed by doctors. Vitamin D has an impact on many facets of our bodies. It protects our bones, our muscles and prevents cardiovascular disease and certain autoimmune diseases.
The vitamin D is a hormone that circulates in our body. It has two origins: the first is endogenous. It is produced in the skin through the action of ultraviolet rays on cholesterol. The second origin is exogenous and is derived from our diet, in particular oily fish, cod liver oil, as well as some plants such as mushrooms.
Once active, vitamin D acts in the intestines and kidneys to absorb calcium and phosphorus and allow its fixation on bone. In other words, it is involved in bone growth. Vitamin D deficiency therefore causes problems such as rickets in children and osteomalacia (loss of bone) in adults with increased risk of fracture. But this is not the only role of vitamin D.
Vitamin D receptors are everywhere in the body, whether the cardiovascular system, neuronal or at the pancreas. In other words, a vitamin D deficiency can occur in diseases such as blood pressure problems, MS or diabetes. Not to mention that it also stimulates immunity and fights against infections, especially in winter.
The vitamin D is vitamin-hormone which is centrally acting in many body functions. The required doses vary by population, colour of skin, age, hormonal status and of course the sunshine rate. CLICK HERE FOR THE MOST POPULAR VITAMIN D SUPPLEMENTS FOR ADULTS
Vitamin D: supplementing baby deficiencies
Babies especially need vitamin D because it is during early childhood that bone strength is acquired. It is therefore sometimes necessary to supplement vitamin D. How do we give vitamin D to infants?
Vitamin D plays a crucial role in the growth of a baby. It promotes the absorption and binding of calcium, essential for a good bone mineralization. Every day, infants should receive one milligram of vitamin D until their 18 months.
Vitamin D is present in our skin. Under the action of sunlight and UVB, it is active and is synthesized by the body and stored. But depending on where you live, winter can be long. Our skin therefore does not get enough vitamin D.
Vitamin D is used to bind calcium to the bone. Lack of vitamin D leaves a bone that will be demineralized and will promote subsequent fractures, especially after the menopause in women. This is why the girls of 10-18 years must absolutely supplement.
From the observations of doctors, vitamin D deficiencies are also the source of some diseases. Vitamin D deficiency may promote certain cancers, diabetes; it could act on the immunity or with a susceptibility to infections or immune problems. Vitamin D deficiency is therefore likely well beyond bone problems.
