Vitamin D and fasting

I know that The Fast Doctor is usually opposed to Vitamin Supplements however what about vitamin D during winter months in the Northern Hemisphere? In some countries such as the UK the sun can often disappear for ruthlessly long spells. During this time we have no way to replenish our Vitamin D reserves other than food, supplements and a SAD light but not sure if this is a good enough replacement for sun light.

Thanks
David

Thanks for the opportunity David.

I do not oppose vitamins, just as I do not oppose antibiotics where necessary, but I do see these two kinds of drugs in the same category: Tu be used at the lowest efficient dosage as short as possible, where really necessary.

There have been a few cases of vitamin D deficiency: The poor Fritzl children in Austria, for example, who saw no sunlight before the age of 20... and the nuns in the monastries, who were covered all over for a lifetime except for the hands and eyes.. THAT's the amount of deficiency of (sun)light exposure that we need to develop Rickets or meaningful vitamin D deficiency.

Supplementation stimulates excretion, leading to deficiency. Supplements are typically refined, hyper-absorbable, bypassing the body's absorption control mechanisms, out of context with micro-nutrients, in short, they find themselves in an inappropriate "ambience".

We need up to 300 different nutrients to be healthy.. and the BALANCE between them is critical. Supplements contain only a select few chemically stable nutrients (of which we already have too much), thus disrupting the balance between stable and unstable nutrients..

But let each individual decide.. hopefully an informed dicision not too much affected by the crafty marketing ploys of the chemical industry.

Blissfully unaware I posted the same question to The Fast Doctor again 2 years later :blush:

I know that as a rule of thumb The Fast Doctor advises against the use of vitamin supplements during a fast and also on non fasting days and the explanation can be found on the site's FAQ however where do we stand with Vitamin D as the body cannot manufacture this vitamin without absorbing sun and research has shown that people are vitamin D deficient during the winter months especially in the Northern hemisphere?

Good topic. I guess people in the northernmost areas (at least those who are not vegetarians) do eat plenty of fatty fish. For vegans shiiitake mushrooms are higher in vit D. I read in some study that a sun exposure of large body part in duration of 5-30 mins twice a week is sufficient to prevent deficiency (Michael F. Holick, M.D., Ph.D).

Does anybody from FC live in areas with dark winter days?

Vitamin D, dear David and Shant, is a relatively new fashion. Some people are making a LOT of money out of this fashion.

Remember we need about 300 different nutrients in a delicate balance. If you take one, you are more likely to upset this balance.

The body makes Vitamin D from Cholesterol. Now that the Pharmaceutical industry has put just about every available patient on "Statins" to reduce cholesterol, they start selling Vitamin D to them..

Vitamin D deficiency has occurred on occasion.. for example the nuns in the monestaries in Europe, who had for decades lived indoors with only a few square centimeters of their faces ever exposed to any light, very seldom direct sunlight if at all. And even among them, this was rare.

Remember that Vitamin D is fat soluble. In large quantities it is toxic, particularly to the liver.

I for one will not take Vitamin D and I will not willfully expose my skin to direct sunlight. I am sure I get more than enough from the incidental and indirect sunlight.

Vitamin D may be a new fashion but the importance of sunshine isn't.

We have an old saying that would be translated into: To whom the sun doesn't go, the doctor pays a visit... or something like that, if my English makes any sense.

I'd say:

Lack of sunshine = depression
Lack of sunshine = less of vitamin D
Less of vitamin D due to less of sunshine = depression
Depression = higher risk of developing illnesses

I like that Shant thanks. A friend of mine received some info on his inbox while we were exchanging emails on the topic. One of those synchronicity moments. It was written in Fench and translated to Google in to English.

Who has not yet taken its vitamin D?!

In February, the people of the northern hemisphere reached their lowest vitamin D year, because many people have most seriously exposed to the sun for the past 5 months

More than 8 out of 10 French lack of vitamin D, that is to say they have less than 30 ng of vitamin D per milliliter of blood. 50% of French people are even less than 20 ng / mL.

A study in the Rhône-Alpes and Gironde between February and April 2009 among 281 men aged 19 to 59 years found that 94% of them lack of vitamin D, more than one in four (27%) being even severe deficiency. The rate was less than 12 ng / mL!

In particular, people over 70 years synthesize 4 times less vitamin D as a young person, comparable to exposure, due to the aging of the skin. An elderly person will almost automatically out little deficient. Similarly, children are often vitamin D deficiency, because too little sunlight.

This is very annoying.

In fact, vitamin D deficiency is linked to a variety of health problems:



fracture risk (1);


risk of certain cancers (2);


diabetes and Parkinson's disease (3);


risk of early death (4);


risk of flu (5);


depression (6).


All these risks can be easily reduced: it is sufficient to inform the public that everyone should take a little vitamin D as a dietary supplement (because you find very few naturally in your food, apart from fatty fish). For me, it is a scandal that the public health authorities remain silent about it: better informing the population, they could save tens of billions of euros each year on health systems, through all diseases would be avoided.

Such information campaign would primarily to save hundreds of thousands of heavy treatments, expensive, painful, when they are not mutilating, for diseases that could easily be prevented with adequate intake of vitamin D .

That is why, at our level, we continue our major information campaign on vitamin D. I urge all readers responsible for S & N not only to take control themselves, but also to talk to their environment by transferring this message widely, and even to offer them all around vitamin D, a gift original, cheap and really useful.


Vitamin D prescribed by doctors
Many doctors today are aware of the problem and think spontaneously bulbs to prescribe vitamin D to their patients.

Generally, however, they are bulbs doses of 100, 000, 200 000 International Units (IU) to take once or twice.

It is not certain that this is ideal. These bulbs are actually rather designed as therapeutic doses, ie to take an emergency to stop obvious symptoms of deficiency.

But this is to take a month in the face of the sun in the space of a few minutes.

Not only it is not physiological because we manufacture some vitamin-D3 whenever we are exposed regularly to sunlight, other body barely use stoker and the massive influx of vitamin D.


Natural ways to have a good level of vitamin D
In principle, vitamin D is produced naturally by your body, under the influence of UVB rays of the sun. But would still have to have enough, expose yourself every day, including the torso, for at least 30 minutes, and at mid-day.

For those of us who live in colder or rainy, or who work in offices, it is a tough challenge from October to March. Taking supplements is useful, and may even be systematic in people over 70 years, the skin absorbs 4 times less UVB than others, and that almost synthesize vitamin D.

But even if you are young you are e highly exposed this summer, you should know that you have made reservations are probably also consumed today, February 1st. In fact, your body consumes 5,000 IU (international units) per day, nearly fifty times that brings your diet.

Unfortunately, you can not even rely on foods fortified with vitamin D, including milk: it is a simple marketing ploy to make you buy without real benefit to you. Foods fortified with vitamin D provide only a small proportion of the official recommended doses. In any case they have no effect on disease could be improved by vitamin D.


How much?
You need a target of vitamin D in your plasma above 30 ng / mL, the optimal rate between 30 and 60 ng / mL. (7)

But as you can not spend your time doing blood tests, you have no choice but to control the amount of vitamin D you take.

In children during growth, including adolescence, to assess needs between 600 to 1500 IU per day. This supplementation is essential - at least for prevention - in everyone (men and women) after 60 years and more after 70 years. We usually recommend 1 000 to 1 500 units per day. (8)

Since 2007 for pregnant and lactating Canadian society recommends oral intake 2000 IU per day.

For a healthy adult, a daily dose of 600 to 1500 IU of additional vitamin D per day is recommended, which is no problem if you buy a supplement correctly dosed. *

Note also that you do not risk poisoning at this dose: according to the global specialist in vitamin D, Professor Holick, "it would probably take between 30 000 and 50 0000 IU per day for a very long period to risk being poisoned.


Choose what form?
There are several forms of vitamin D in the trade. But one is vitamin D naturally produced by the skin is vitamin D3, or cholecalciferol.

It seems it has a higher biological activity because, when it gives men a dose of 50 000 IU, the rate remains higher in the blood after three days when there are other forms of vitamin D, such as D2.

To facilitate absorption, you should consume your vitamin D3 with fat, so in the middle of a meal.

You can find a pharmacy where it costs only a few dollars, but it is difficult to know the origin, natural or not.

Some laboratories sell natural food supplements vitamin D3 directly oily form and organic. I personally find that it is more convenient:


You have a small bottle designed to be transported without risk of breaking, and you may have permanently in your desk drawer, your purse-to-hand, or even your pocket.


One bottle lasts six months or a full season of vitamin D (October to March) for one person.


Just take one to three drops directly on the tongue, at any time of the day (it has no taste, except perhaps a slight taste of orange).


The bottle has a pipette that allows you to easily take your drops, without the risk of overdose.


There is no bulb to break or swallow tablet or capsule indigestible;


You do not absorb or questionable chemical additives along with your vitamin D.


To my knowledge, two brands marketed in France vitamin D3 this way: Lescuyer the laboratory and the laboratory-D plants.

Terms of quality of vitamin D3 is equivalent: it is in both cases an oily form of cholecalciferol highly absorbable. The vials contain, in each case, 20 ml of vitamin D3.

The difference is that, in every drop, you have 100 IU of vitamin D3 400 IU at home against Lescuyer-D plants.

For 1200 IU per day, so you should take 12 drops of the product Lescuyer (available here), but only 3 drops in D-Plants (available here).

The bottle-D plants is more expensive (23 euros against 16 euros), but you'll need to buy one for the season, against two in the other case.

Note that vitamin D3 is, experimentally, a potent inhibitor of tumor. It can "order" of cancer cells behave like normal cells again. It promotes cell suicide and slows their proliferation. (9)

But there are other forms of vitamin D3 commercially available, such as vitamin D in tablet form (eg here), Solgar Vitamin D3 in organic stores in the form of softgels (kinds of capsules), and of course products sold in pharmacies.

It is up to you to make the choice.

To your health!

PS: Please note that taking vitamin D will reduce your risk of catching the flu this year.

In the northern hemisphere, influenza occurs mainly from October to March, while in the southern hemisphere, it occurs from April to September. If you look at the data on influenza epidemics in the United States and France from 1972 to 2008, we see that the peak of the epidemic occurred once in November, four in December, 5 in January, 12 times 4 times in February and March.

These outbreaks coincide with the lowest vitamin D levels in the population during these periods.

Vitamin D is an important topic that we published last November a folder full Health & Nutrition about it. You will receive a bonus if you subscribe today. To subscribe directly to folders Health & Nutrition, go here.

Notes

* In France, the authorities have arbitrarily set the RDA (Recommended Daily, 200 IU per day, 5 micrograms, but this figure is not based on any scientific justification. Studies on vitamin D showed a preventive effect from a dose of at least 1000 IU per day (25 micrograms).

My husband had his vit D tested in October, after our winter, it was 18. He was put on the supps by our Doctor and now his vit D is 71. So they do work or perhaps because it is summer here, there has been a big change.

My Vit D is 40 and my Doc wants me to Supp with Vit D. What is posted here it's in the normal range but the ranges have changed in Australia recently and now anything below 50 is Deficiant. I don't really like taking Supps but figure a couple a week rather then everyday should be a compromise.

I have heard people saying that they feel alot better on them, so perhaps it is useful for depression. I am still wary of taking pills in any form, The wise doctor is right in saying it is a delicate balance. I spend 1-2 hours outside a day so am surprised I need to supp. It's a puzzle for sure.
