Calcitriol3D an Molecular model of Vitamin D

The human body requires a balance of different vitamin and mineral nutrients; and, an excess, or a deficiency, of any particular nutrient can cause us health problems ranging from very mild to very severe; and, in rare and untreated cases, can even cause death. Prior to the 1930's, a disease called 'Rickets' and other growth and bone problems were major concerns in the United states, and this was caused by a deficiency of Vitamin D (look wecanwait4u.com/cognishield-reviews.html).

However, that particular public health problem was successfully addressed by the US government's introduction, in the early 1930's, of vitamin D fortified milk: since that time, it has been mandatory to add 400 IU's of Vitamin D to every quart of milk processed and sold in the United States. This precaution led to a dramatic decline in the number of cases of bone diseases, such as rickets. A symbiotic relationship exists between some vitamins and minerals; one often depends on the other.

For example, deficiencies of Vitamin D can also lead to impaired intestinal absorption of the minerals calcium, iron and magnesium; which can, and does, lead to many other serious health problems in lots of people. A common problem, in post menopausal women, is that a vitamin D deficiency can cause 'osteoporosis', which is a lessening of bone mass and density, better known as 'Brittle Bone Disease' and this can lead to an increased risk of bone fractures.

Vitamin D is also sometimes referred to as the 'Sunshine Vitamin', this is because it was discovered that, provided we are exposed to sufficient amounts of sunshine, our bodies can actually manufacture their own Vitamin D. Our bodies can synthesize Vitamin D from one of the other substances in our bodies. Would you believe it, that substance is cholesterol!

A Word of Caution

Taking large amounts of Vitamin a, over a prolonged period, can cause toxicity within our body: this is particularly so with the liver. However, in modern times, more is understood about the importance of having the correct balance of nutrients in our diets, and many of the older problems, which were caused by vitamin or mineral deficiencies, or excesses, have now become rarer. Doctors today now know which of the foods that we eat contain which different vitamins and minerals.

However, there is still the possibility of the body suffering health problems through an excess intake of the fat soluble vitamins. So called because they can not be eliminated from the body quickly. The fat soluble group of vitamins are stored in our fatty tissues, and in different organs throughout our bodies.

The human body's regulation of the levels of the ADEK vitamins is not as efficient as it is with the water soluble vitamins and long term ingestion, at levels higher than the recommended daily allowances, will cause a build up of toxic levels of fat soluble vitamins within the body. Tests have recorded toxic symptoms of the fat soluble vitamins E and vitamin K. However, the test were inconclusive and it has been difficult to establish the effects of long term high levels of consumption of those.
