Last moment of the year for your vitamin D

We are approaching the last days that you can expose yourself to the sun and store of good vitamin D. A good vitamin D levels (between 50 and 65 ng / mL) helps prevent and treat certain cancers, autoimmune diseases (including multiple sclerosis and type 1 diabetes), depression, fractures, infections (flu, colds) and a myriad of other problems.

 

A good vitamin D levels (between 50 and 65 ng / mL) helps prevent and treat certain cancers, autoimmune diseases (including multiple sclerosis and type 1 diabetes), depression, fractures, infections (influenza, cold) and a myriad of other problems.

This is part of the largest single health measures.

If you were a native of the tropics spending most of your time outdoors, you would not need to worry about your vitamin D.

But if you live in an apartment without a sunny balcony, if you work in an office or in a factory or an illuminated workshop in the electric light in a retirement home, or worse, in a hospital, you are certain to miss vitamin D

Vitamin D, a scarce resource in temperate countries

You produce vitamin D without thinking every time the sun is high in the sky and its rays caress your skin.

Ultraviolet B (UVB) then turn a precursor of cholesterol found in your skin into vitamin D3, which experts call "cholecalciferol".

The problem in our latitudes (France, Switzerland and even Belgium, England and Quebec), is that the wavelength of sunlight is not sufficient for the synthesis of vitamin D3 throughout the year, which becomes a scarce resource and precious.

The higher the sun is high in the sky, the more its rays trigger vitamin D3 formation. But:

  •     when the sun sets in the evening,
  • and when the sun is low in the sky during the autumn months, winter and spring, in European countries and in North America ...


... The beam wavelength is too long. You put yourself in the sun beautiful, even tan, for example skiing, the sad reality is that you no longer manufacture all vitamin D.

Vitamin D is synthesized when the long wavelength solar radiation is between 290 and 315 nanometers. A country like France does not receive any radiation below 313 nm between February and November. At the latitude of Paris, we do not manufacture vitamin D at all between mid-October and mid-April [1]!

3 out of 4 in vitamin D deficiency

The consequence is that, in all likelihood, you spend six months of the year or more in total deficit of vitamin D. In France, in winter, 74% of men and 78% of women with vitamin D deficiency [2] .

The result: tens of thousands of full coffins when they could be left empty.

According to a study by three specialists of vitamin D - Grant WB, Garland CF and MF Holick - if only Britain received as much sun as Florida, there would be 22,000 dead in less than nothing cause of cancer [3].

Your reserves depleted by mid-October

You should know in fact that during the summer months, although if we expose ourselves to the sun, we accumulate every day until 10 000 International Units of vitamin D.

The International Unit (IU) corresponding to 0.25 micrograms of calciferol. Now the body consumes about 5000 IU per day. The reserves of the summer, even when they are strong, so are generally exhausted from October to November in the northern hemisphere. [4]

Expose yourself to the sun so whenever time permits, for 15 minutes.

Then, from mid-October, take a daily supplement of vitamin D.

Health authorities recommend 200 IU daily but all specialists worthy of the name recommended 7-10 times the dose (ie 1400 to 2000 IU per day). [5]

The advantage of the food supplement daily, with respect to the flash dose of 100 000 or 200 000 IU prescribed by doctors is that it gives you your vitamin D gradually, in the way the body naturally receives (or should receive course, if we still lived in the open air as our ancestors).

Take Uvédose 100 000 IU suddenly comes back to take a month of bright sunshine in the figure, which might not have all the same beneficial effects for the body. Yet it is as it is sold in pharmacies.

By cons, a food supplement with natural vitamin D3, you no risk.

No risk of intoxication

There is no risk of intoxication with vitamin D to 1000, 2000 or even 5000 IU per day, and the cost / benefit ratio is huge.

According to Thierry Souccar:


"According to the literature, it is possible to take up to 10 000 IU per day for at least 5 months without toxicity. It would probably take between 30 000 and 50 000 IU per day for a very long time to be intoxicated. The typical vitamin D intoxication is due to unintended catch of hundreds of thousands, even millions of units over a longer period. It occurs only very rarely. [6] "


Make a dosing every year in November

Every year, I advise you to do your dose vitamin D in November. You should ideally aim at rates between 50 and 65 ng / mL. It is here that you will be better protected against infections and diseases.

The blood test can be done on prescription but you can also get it on your own with the laboratory analysis you choose.

No cod liver oil!

The cod liver oil is rich in vitamin A, which can be interesting if you miss, but do not take it if you want to straighten your vitamin D levels

Vitamin A night in large quantities to the action of vitamin D.

The best is to take a vitamin D obtained by exposing lanolin (wool wax) UVB radiation, which produces cholecalciferol (vitamin D3).

Note finally that some recommend vitamin D2 rather than D3, but that recommendation has no scientific basis. In contrast, vitamin D2 is destroyed quickly by the body. The analysis of studies using both forms of vitamin D found that supplements of vitamin D3 reduces mortality (particularly among older women) but the D2 has no [6] effect.
