German vitamin d for children

Vitamin D helps the body to maintain the level of Calcium and is essential for bone german vitamin d for children. It also maintains the Phosphorus level in the human body.

Vitamin D is found in three different forms. Cholecalciferol or Vitamin D3 is the naturally occurring one and is the most effective form of vitamin D. However, the general term Vitamin D includes the chemically modified forms and metabolic products such as calcidiol and calcitriol. With the increased use of sunscreens, minimum exposure to sunlight and the absence of sunshine in the colder climates, it has become a necessity to include supplements to diet to compensate for the daily intake requirement of Vitamin D. These non prescription dietary supplements include Vitamin D3 as well as Vitamin D2 or ergocalciferol.

The comparison of Vitamin D and Vitamin D3 essentially includes the comparison of features of vitamin D2 and Vitamin D3. Each of the molecules has specific functions, metabolic pathways and attributes although the term Vitamin D proves generic. This is the naturally occurring form of Vitamin D in human. The vitamin is found in dairy products, fortified milk, sea food, etc. The WHO has reported osteoporosis as a major global health care problem, second only to cardiovascular issues.

Maintaining a balanced diet with Vitamin D will help to prevent the disease. Although the vitamin can be manufactured by adequate exposure to sunlight, this is not practical since the incidence of skin cancer and associated risks are on the rise. So it is advisable to include the vitamin as a supplement in diet. When it comes to supplements, most doctors prefer the naturally occurring form.

Since it is easily available from various food sources and undergoes the usual metabolic pathway in human, there are no side effects to the D3 supplements. Research has proven that supplements of vitamin D3 together with Calcium can decrease the risk of bone fracture in geriatric patients. There has been proven incidences of the protective effect of vitamin D3 against colon, prostate and breast cancer in elderly people. Vitamin D2 is the other form of vitamin D which is derived from ergot fungus. This form undergoes metabolism in human and is converted to other products like calcitriol. Calcitriol is the most active metabolic form which is involved in the maintenance of calcium and phosphorus levels in the body. It is of plant origin and commonly found in supplements.

It is also found effective against psoriasis. The vitamin has several regulatory functions such as P-Ca metabolism, ossification process, and absorption of amino acids in renal tubules in kidneys. Metabolic side effects such as hypercalcemia, hyper calciuria, and general side effects such as allergic reactions and stomach cramps etc have been reported even though the incidence is quite low. Vitamin D3 is naturally occurring whereas vitamin D2 is derived from plant. Hence the metabolic pathways are different and so does the use of metabolic products in the pathway. The only metabolic product of ergocalciferol which has some purpose in human body is Calcitriol.

Other products do not serve any functions and need to be metabolized for elimination. Vitamin D3 needs smaller doses since the potency is higher. The dose needed to elicit a response is inversely related to the potency. Vitamin D3 can elicit the responses faster. Studies have indicated a dietary dosage of 4000 I. U is enough to meet the daily requirement for a normal adult. It means that the vitamin is effective in microgram quantities.

The metabolic products of D3 are quite useful to the humans and find a specific function. D2 vitamin however enters the metabolic pathway to form products which are not useful to the human body. These products are found to be non toxic. The body metabolizes D2 more quickly than vitamin D3 and this can be the cause of such side effects.

The  life of vitamin D2 is less than that of vitamin D3 and is absorbed poorly. This means the vitamin D2 is quickly metabolized to other forms. Although the two forms of vitamin D are available and are prescribed, when the side effects and benefits are weighed and analyzed, vitamin D3 stands the test. Since this is naturally occurring, the incidence of adverse drug effects is rare and is the biggest plus point. Vitamin D2 supplements hence must be limited to extreme or special cases of metabolic failure as in a genetic defect.
