Vitamin D : underestimates deficiency

The vitamin D deficiency may be the source of many debilitating conditions. Its role, however, is neglected by the authorities who inexplicably minus recommendations for recommended daily allowances. Western though superabundant supply, is destitute of certain essential nutrients. This is the case, especially for vitamin D, leading to an exaggerated frequency of certain diseases, accelerated aging and an unacceptable number of premature deaths. This was highlighted at a recent meeting of experts in Lausanne.



What is Vitamin D?

Vitamin D is essential for:

  • Intestinal absorption of calcium and phosphorus
  • The prevention of rickets in children, osteomalacia in the elderly and postmenopausal osteoporosis.
  • Prevention including winter infections, but also of certain cancers (breast, ovarian, prostate, colon) and non-Hodgkin's lymphoma.
  • The prevention of type 1 (juvenile diabetes) and multiple sclerosis diabetes?
  • Protection against atherosclerosis and cardiovascular disease?

A rare vitamin Sources of vitamin D are twofold: first, exposure to light, the other fatty fish (oil livers, especially including the famous cod liver oil) and shellfish. Neither one nor the other of these sources are sufficient to meet the needs of the general population in winter sunlight are too inclined to the horizon for the efficient processing of the precursor to vitamin D. And, all the year, consumption of adequate marine products is below recommendations regularly broadcast (three 100 grams per week of fish from wild oily sea).

Prospective studies at the European Community, 36% of men have a significant deficit, 47% of women, 60% of people over 75 years ... 90% of people in institutions. Daily intakes dangerously undervalued AFSSA states that "recommended dietary vitamin D were defined by considering that endogenous production covers 50-70% of the daily requirement of this vitamin." Daily intakes for persons under 65 years of age, initially measured at 10 micrograms / day, however, were reduced to 5 micrograms / day in 2000 incomprehensibly while all international studies on this subject say that action actually preventive and / or curative can not be expected without multiplying by four or five the recommended daily intake.

How to avoid the deficit?

Through exposure to the sun without excess, the summer before and 11 hours after 15 hours. Outside this period, the exhibition will be less effective, especially in the northern regions and megacities covered with a cloud of pollution.

Consuming 100-120 g fatty fish and wild sea two or three times per week (sardines, mackerel, pilchards, salmon, tuna or other species with dark flesh), sometimes relayed by cod liver or shellfish.

The use of liver oil halibut or cod capsules allow effective and safe supplementation in compliance with the dose recommended by the manufacturer.

The use of prescription only as the presence of a disease among those mentioned above.

What form to choose?

There are several forms of vitamin D in the trade. There is a long debate between the defenders of the D2 and those who swear by the D3. However, it seems

It also seems that it has superior biological activity, because when we give men a dose of 50,000 IU, the rate remains higher in the blood after three days when it is other forms of vitamin D as D2.

To facilitate absorption, it is preferable to use vitamin D3 with fat, but as most manufacturers sell directly vitamin D3 in oily form, this precaution is usually not necessary.
