Today we will talk about an element which name takes away us deep into the Scandinavian mythology, straight to the goddess of love Vanadis. Yes, it will be a question of vanadium, of metal of rare beauty which besides has a number of properties, useful to our organism.
Description and characteristic
In periodic Mendeleev's system vanadium has designation V and number 23. This metal having plasticity was found at the beginning of the 19th century in lead ore. Then opening did not become known, and the element had to wait for the hour of triumph almost thirty more years.
The uniqueness of vanadium is that its connections possess the most various color palette and never meet in itself — always as a part of iron or titanium.
Vanadium is not a rare element, its presence at earth crust makes about 160 g on 1 t. The most probable place where it is possible to find deposits of this metal, the breed of magmatic origin is. At addition to vanadium of impurity it is possible to receive very firm, but at the same time fragile alloy.
Functions and role in an organism
If we take for an example of the average person (it what it is drawn in textbooks of biology — tall, with body weight about 70 kg), then we will find 0.11 mg of vanadium in his organism. We will find it first of all in blood and in a skeleton, then in cages, and then already and in tissues of some internals (heart, lungs, a thyroid gland, kidneys).
Whether you know? In narrow research circles it is considered that vanadium can prevent formation of cancer tumors.
It is impossible to claim with confidence that the role of element No. 23 for a human body is completely investigated. Even more widespread elements need further study. However the vanadium role in some important processes is open and proved today:
- warm regulation;
- carbohydrate exchange;
- metabolism in bone tissues.
If to speak absolutely simply, then the considered element is the important catalyst in our internal laboratory. Connecting to hemoglobin or transferrin, it protects them from oxidation. Assimilation and synthesis of many substances, useful to an organism, would not be possible without this metal. Its ability to become inhibitor for some enzymes allows an organism to reach power balance. Also its influence lowers the level of Q and A coenzymes.
Scientists noticed that ions of vanadium slow down process of synthesizing of fatty acids and cholesterol.
Learn everything about saturated and nonsaturated fatty acids.
And it means that are stabilized fat and lipidic exchange. It in turn influences a condition of vessels, doing them healthy. Also elevated pressure is stabilized.
Also the fact of influence of an element on nervous system and kidneys is established, but how this influence happens, at a research stage.
What contains vanadium: products sources
The shortage of vanadium about which we will talk further happens seldom. However it is worth knowing in what products it contains. First of all this fat meat and liver. Further there is seafood, and champions on the maintenance of element No. 23 are mollusks. Thus, hobby for oysters not only is refined, but also it is useful.
Important! Correction of a food allowance — the only way to correct the health. Do not take any special drugs containing vanadium at all!
The fastest and available way of replenishment of vanadic stocks are cereals, especially porridge, buckwheat and the crude rice.
Its haricot contains 190 mkg on 100 g of a product, in a garden radish — 185 mkg, in barley grits and wheat — on 172 mkg. Further there are pistachios, lettuce leaves, potatoes and young peas. In them on average in 150-170 mkg on 100 g. Using vegetable oil, mushrooms, greens and beet you also resupply this precious metal.
Read what greens of parsley, fennel and rosemary are useful.
If to exclude fat meat and a delicacy like oysters from our list, then it will turn out that the usual healthy food including porridges, vegetables on a season and oil fills such useful and very available element as vanadium in an organism. Probably, it is one of the reasons why food simple food improves health.
Daily requirement and norms
In general the standard daily rate of vanadium for the person is 0.05 milligrams. At all multiple advantage of this metal the question of extent of its influence is up to the end not studied. The western bodybuilders, having learned about influence of an element on skeletal system and work of muscle, began to apply actively in the diet nutritional supplements with its concentrated contents. However in the light of one private controlled research in which more than 30 athletes bodybuilders participated we can tell that these additives — no more than placebo for internal motivation. The fact is that the experiment offering to the participants a thousandfold daily dose of vanadium did not reveal any superpositive influence on an organism.

Deficiency and surplus: reasons and symptoms
Any substance, microcell, enzyme, hormone and so on in the systems of our organism bears a certain function and is useful. But we know many cases of various diseases when the critical shortage or too large number of any component is observed. Whether it concerns vanadium?
Whether there is a shortage
As we practically never hear about that salutary role which is played in a human body by vanadium, it is easy to draw a conclusion that its shortcoming is not considered by official medicine as a problem yet. The person has no recorded cases of critical shortage of this element of unit and accurate symptoms of such state. However the experiments made by scientists on animals showed what consequences of shortage of this modest element:
- Problems with development of skeletal system.
- Development of diabetes.
- High mortality of newborns, abortions.
Overdose and harm
If to consider a situation on the other hand and to assume that there can be a vanadium surplus then there can be a poisoning leading to pathologies of nervous system, the high pressure and anemia.
Whether you know? Very few people know, but the considered metal normalizes the content of sugar in blood, and its connections are often appointed together with insulin at treatment of diabetes. At early stages of a disease insulin can even not be necessary — for symptomatic treatment there will be enough also compounds of vanadium.
After all you should not forget that the element discussed by us is metal, and its constant satellites not only oxygen, but also sulfur, chlorine and sodium. But actually the overdose of V is a caution from area of a fantasy unless nearby there will be a technogenic catastrophe.
Poisoning with the products containing vanadium is also impossible if only they did not receive it as a result of any industrial pollution. This element is most toxic if it to inhale in the concentrated look (gasoline steam inhalation, long contact with the air infected with industrial wastes).
Interaction with other substances
The last researches in the field of interaction of chemical elements showed that fluorine, selenium and zinc will become best company to vanadium. These elements play a positive role in a tandem, taking part in various biochemical processes of an organism. And here chrome and ascorbic acid — antagonists of vanadium. People who take the blood-thinning drugs should be especially careful with the nutritional supplements containing vanadium. This element reduces positive effect from intake of these medicines.
Important! Vanadic nutritional supplements are categorically contraindicated to children and women in situation. Their influence is up to the end not studied and can cause organism intoxication.
Knowledge of advantage of any given elements is necessary for the modern person. Perhaps, this scientific research will force us treats the diet and a day regimen, an ecological situation around us more attentively. The main thing — in everything to observe a measure.
