Certain minerals are far from toxic, because, even in very strong quantities, they are badly absorbed. It is the case of the vitamin K, which becomes only toxic in the event of excess of vitamin D which intensifies its absorption, or in the event of osseous demineralization, where it can go to settle in the kidneys, the vessels, around the articulations (periarthritis) or even in the brain.
This calcification of tissues known as "soft" concerns mainly old people. In order to prevent it is necessary to keep a balance with the magnesium, which precisely controls its penetration in these soft tissues
Magnesium protects thus, in the majority of the situations against pathological situations, just as the cardiac insufficiency treated by the digital ones makes it vulnerable to vitamin K, ( deposits organism of undesirable vitamin k, and directs in the contrary the vitamin K towards the bone.
Can excess magnesium be dangerous? A great part of ingested excesses will not be absorbed and will cause a diarrhea. As for the absorptive surplus, it will be eliminated in the urines, except in the case of a renal insufficiency, where the elimination of excesses is hurt and where any substance can more quickly become toxic than in normal case.
However, other situations require a careful handling of magnesium: cystitis, bradycardia, and myasthenia.
It is never judicious, in general, to take more than it is not necessary. Not more than to remain with deficits.
But, according to doses, the properties of an element can change so much so that with excessive doses it can produce the contrary effect of its normal effect. Such is the case of the zinc which, with doses 10 times higher than those recommended, can weaken anti-infectious defenses whereas it reinforces them with less stronger doses.
But such excesses are technically impossible to obtain by (food They can occur only at the time of supplementation with "mega doses". Nevertheless, in the case of iron and copper, it appears that, for a large part of the population, a contribution considered as within the higher limit of the normal can be negative.
Indeed, iron and copper are trace elements pro-oxidants which, in certain situations, increase the free emissions of radicals and damage, related to the aging.
Studies show an increase in the number of cancers and cardiovascular pathologies when the contributions of iron or copper or the rates proportioned are within the higher limits of normal.
If the majority of women tend to miss iron before the menopause, the men rather tend to have excess iron. Certain authors think that the monthly iron rules and losses which they cause - constitute one of the factors which contribute to higher women longevity compared to men.
Some give new ideas for men with excess weight the bleeding doctors during Molière time. But it is easier to give blood, to eat less red meat and drink tea, a powerful inhibitor for the absorption of iron, at the end of the meal.
Other researchers indicate that the contributions recommended in copper could be divided by 3. In any case, in nutri-therapy, we believe that in the contrary the current supplementation for heavy doses comes from the Atlantic, an excess is not always good.
SSo certain protective elements are not brought in sufficient quantities, and even if sometimes the amounts recommended are insufficient, other elements seem to be brought in excessive quantities in any case, for important groups of population, the quantities recommended could even be reduced.
What is sure, is that it is absurd to maintain systematically, in the minero-vitaminic complex, of iron and copper as these contributions can have negative effects when we do not have these elements
We should give iron or copper only to the subjects which present a deficit objectified by a proportioning. Especially as association, in the same formula, of iron or copper and the vitamin C can produce free radicals in the tablet or the pill and copper appears to return the vitamin E and beta carotene pro-oxidants as they are normally antioxidant.
Lastly, the presence in the same iron and zinc formula led to a reciprocal inhibition of their absorption. Curiously, in quasi totality of the currently available complexes on the market it became absurd and appear potentially negative; important updates are claimed, in the latest studies published these last years.
It is what Dr. Jean Paul Curtay by the request of a large homeopathic laboratory decided, a few years ago, to open a department of nutri-theraphy.
The opportunity to place at the disposal of doctors and the public information which appears revolutionist even in the United States, concerning synergies of micronutrients, minerals, trace elements, vitamins, acids fatty and amino compatible, without being satisfied with a commercial message centered on the supplementation.
It is clear that to propose a supplementation simply is not enough. The optimization of the food, the environment and the practices remains the base that adapted supplements come to supplement.
