How does taking medication affect the absorption of vitamins? Vitamins: taking vitamins, assimilation of vitamins, compatibility of vitamins
Features of the absorption of vitamins by the body
To ensure the normal functioning of the body you need to take care of getting a full range of vitamins. Their total number is 13. But it is important to know that different vitamins are absorbed in different ways by the body.
The first thing you need to know about vitamins, that they can be taken from food, as well as tablets. Today there is a perception that vitamins that enter the body in a natural way are more beneficial and their absorption is better. However, this is not quite true. Scientists have proven that substances obtained by different methods have the same activity. That is why such rapid absorption of natural vitamins as well as synthetic ones does not occur.
Getting a full range of natural vitamins is a more complicated process. This is due to the fact that inside the vegetables, as well as fruits, the vitamins have a bound form, so their absorption occurs much worse compared to chemical analogues. A person must necessarily support his body with chemist's. This all has nothing to do with just one vitamin E. Its synthetic variety is less active than natural.
Getting all the necessary vitamins from natural products is a daunting task also because after processing they lose most of the beneficial properties. This refers to cooking on the fire, as well as salting. However, there is a method of preparation in which the vitamins are not only preserved, but this fermentation is further activated. This means that sauerkraut contains more digestible vitamins, compared with fresh.
Also important is the knowledge of how the compatibility of vitamins affects the degree of their digestibility. There are substances that are in good contact and are complementary to each other, others are an obstacle for the body to absorb, blocking antagonists. With the use of antagonistic substances, of course, you can not harm the body, but do not bring him good. With this option, you will simply consume a pacifier, because vitamins will be neutralized inside the body. Especially large number of antagonists differ in vitamins B12, as well as calcium with iron.
Finally, the digestibility of vitamins is determined by the time you take them. It is better to start taking vitamins at the beginning of the day, avoiding taking them in the evening when the body gets tired and gets ready for sleep. Also do not forget about taking vitamins when you eat. The absorption of vitamins during meals is better, as well as the consumption of dietary supplements.
Winter is coming to an end and as always we remember about vitamins. But which vitamin is not enough for us and not everyone knows where to get it. Vitamins that prolong life.
1. Vitamin C.
With a deficiency of vitamin C, ascorbic acid whole body healthweakness, lethargy, frequent colds, bleeding gums, long healing of wounds, sleep disturbance. Vitamin C is an important vitamin, affecting health and longevity. Without this vitamin in the body, no processes are possible: it increases the body's resistance to external influences, infections, regulates cholesterol metabolism, promotes the absorption of proteins, iron and a number of vitamins by the body. Vitamin C should be ingested daily, its reserves are small, and consumption is uninterrupted. The more protein you eat, the more vitamin C you need. An overdose of vitamin C, if you get it in its natural form, is not terrible. Vitamin C is destroyed in the storage of vegetables and fruits in the light, culinary processing (immersing potatoes in boiling water before cooking almost completely retains vitamin C in it), when adding soda or salt to food, when warming soups, etc. Vitamin C is better stored in acidic environment. Vitamin C contains sweet pepper, citrus fruits, sauerkraut, wild rose, cranberry, kiwi, sea buckthorn, black currant, parsley, dill, cabbage, sorrel, spinach, mountain ash.
2. Vitamin A - retinol, carotene (prolonging youth).
With a deficiency of this vitamin appears fatigue, dryness and peeling, pustular skin diseases, blurred vision, attention, photophobia, lacrimation, susceptibility to infections. The body's need for this vitamin should be provided by 1/3 of products containing retinol and 2/3 of products containing carotene. Retinol contains butter, egg yolk, kidneys, liver, dairy products; carotene-apricots, carrots, cabbage, lettuce, potatoes, plums, all yellow fruits. When cooking food without access of oxygen (with the lid closed), vitamin A is stored well. Destroyed under the action of sunlight, when burning fat.
3. Vitamins of group B .
To increase longevity and maintain health, ALL B vitamins from group B are needed. Vitamin B1 - (health of the intestines, nervous system). With a vitamin deficiency, a decrease in performance, weakness, constipation, headache, memory impairment, shortness of breath, palpitations, and tearfulness occur.
Vitamin B1
contains wholemeal bread, beef liver, cheese, mackerel, cottage cheese, egg yolk, cod, whole buckwheat, oatmeal, nuts, green peas, spinach. High-grade flour products, dairy products, vegetables, and fruits are poor in vitamin. When cooking is lost from 20 to 40% of vitamin B1. It is destroyed in an alkaline environment, when adding soda to the dough or for quick cooking of beans and peas.
Vitamin B2, ryboflavin
(health of lips, eyes, skin). With a deficiency of this vitamin will be poor eyesight, hair loss, frequent boils, herpes, chronic colitis, gastritis, weakness, skin diseases, depression, nervous system disorder. Vitamin B2 deficiency appears after a rather long time, but it is his absence in the diet that shortens the life span. Vitamin B2 contains beef liver, eggs, cheese, mackerel, cottage cheese, cabbage, fresh peas, apples, almonds, green beans, tomatoes, turnips, oats, leeks, potatoes, whole grains of wheat, beef, and dairy products.
Vitamin B3 - Nicotinic Acid
(antiallergic). Vitamin deficiency most often occurs with a monotonous diet (only cereals or only potatoes), which can lead to the appearance of pellagra. This disease affects the skin, mucous membranes, can cause neuropsychiatric disorders. Vitamin B3 contains animal products - meat, liver, kidneys, dairy products, buckwheat, mushrooms, soybeans, sprouted wheat.
Vitamin B5 - pantothenic acid (prolonging life) .
The deficiency causes metabolic disorders, dermatitis, cessation of growth. Vitamin B5 is found in brewer's yeast, egg yolk, liver, dairy products, green parts of plants (turnip tops, carrots, etc.), in cereals from uncrushed cereals.
Vitamin B6 - pyridoxine
(health of hair, nails). Together with calcium contributes to the normal functioning of the heart muscle. Otitis is often caused by a lack of vitamin B6 in the body. Vitamin B6 contains meat of animals and birds, wholemeal bread, buckwheat, barley, barley, millet, liver, mackerel, beans, potatoes, bran. The need for vitamin B6 increases with atherosclerosis, liver disease, toxicosis, pregnancy, gastritis, anemia, prolonged use of antibiotics and anti-tuberculosis drugs.
Vitamin B9 - Folic Acid and Vitamin B12 - Cyanocobalamin (blood health)
With a lack of vitamins B9 and B12, anemia develops in food. Deficiency can occur with vegan nutrition (without milk, eggs, meat, fish) and a violation of the assimilation of vitamin in gastritis, enterocolitis, worm diseases. Vitamins B9 and B12 contain dairy products, eggs, soy, brewer's yeast, green parts of plants (tops), lettuce, green onions, beef liver, liver pate (no more than once a week with vegetables, which should be three times more) .
Vitamin E - tocopherol
("Fertility vitamin"). Vitamin E provides the functioning of the heart muscle, is effective in the treatment of diabetes, asthma, prevents the formation of blood clots in blood vessels. Vitamin E contains cereals, vegetable oils, eggs, liver. Vitamin E should be consumed only in combination with retinol (vitamin A) and food containing vitamin E should be used together with vegetables, potatoes, cabbage, lettuce, carrots, green parts of plants.
Vitamin D - Calciferol
(bone health). With this vitamin cure eye diseases and some types of arthritis. When it is deficient, lethargy, fatigue, frequent runny nose, osteoporosis occur. With a lack of vitamin D in the diet and with a long absence of sunlight, the bones of the child, not receiving vitamin D, soften and rickets occur. To avoid vitamin D deficiency, wash your hands with soap less often (reasonably shortening the procedure). Contrast douche stimulates the production of vitamin D in the body, keeping the skin healthy, young, beautiful. Exercise for capillaries - closing the feet and palms - helps to avoid a lack of vitamin D, as it creates a natural massage of the internal organs.
WHY VITAMINS DO NOT DECLINE
Causes of vitamin deficiency when nutrients are not absorbed by the body , need to look in the digestive system. With diseases of the stomach, biliary ducts and especially the intestines, partial destruction of vitamins occurs, their absorption deteriorates, and the formation of some of them by the intestinal microflora is reduced. Vitamin uptake fades away with helminthic diseases . Some drugs have antivitamin properties: they inhibit the intestinal microflora, which affects the formation of vitamins, or disrupt the exchange of the latter in the body itself.
Prolonged excessive use of vitamin preparations can also disrupt the metabolism and have a toxic effect, until the occurrence of the disease hypervitaminosis (especially vitamin A and D).
Spring is just around the corner! And most modern people go to pharmacies to buy vitamins in order to protect themselves from beriberi. After all, spring and vitamin deficiency are practically synonymous with us. But why do we so blindly believe that purchased synthetic vitamins benefit health ?! As we like to shift responsibility for our own health to strangers who produce vitamins from chemical raw materials and get richer from year to year. My family and I refused to take such vitamins, because we know that synthetic vitamins are not absorbed by our body, and we should not!
The human body is so harmonious and unified system that all outstanding scientists of all times bow down before the genius of the created organism, in which everything is interconnected and works like a clock. Intervention in this mechanism from outside does not bring benefit, and even more, harms it. Our body is absolutely natural, and the closer we are to nature, the better for us. And our enzymatic system can take in itself only natural substances, and synthetic ones simply simply cannot be absorbed by our body. And this is the answer to the question - why synthetic vitamins are not absorbed.
I feel that rotten tomatoes will fly into my sides! Like, now all the products are of poor quality, and a person does not get the right amount of vitamins from food! Yes, I agree, it is really difficult now with natural products, but this is not a reason to stuff yourself with another batch of chemistry. Let's talk together! It is easier for us to go to the pharmacy and, having bought the advertised drug, calm my own mind with the thought that now in my body there will be all the necessary substances and vitamins, thus I reduce the risk of the disease to a minimum. We do not want to delve into the theory of healthy food, we do not want to cook healthy and not always tasty dishes, we do not want, we do not want to do gymnastics or do yoga, we don’t have time and desire for all this. And we need a guarantor that we have done something useful for our own body, so we buy vitamins, we are just so calmer. It turns out that we do not buy vitamins, we buy our own peace of mind.
Why are synthetic vitamins not absorbed?
And this section of the article is for those people who need facts, not words. It turns out that scientists have not yet learned how to synthesize a single vitamin! All synthetic vitamins have a completely different chemical composition than the natural ones. Scientists in laboratories have learned to reproduce only a small part of the formula of natural vitamin. For example, vitamin C - in nature, it consists of 7 ascorbic acid isomers, which are linked together in a strictly defined way. In pharmacy vitamins, only 1 isomer is present. The rest of the scientists are simply not yet synthesized. Or vitamin E - only 1 of 8 tocopherols are synthesized.
This is partly due to the fact that modern scientists do not know how to reproduce the formula, partly because artificially synthesizing all vitamin isomers is a very expensive process and pharmacological companies are not interested in large expenses. What do we get in the end? The fact that in pharmacies we buy an eighth of the vitamin! As a result, the body is trying to repel these artificial substances that are incomprehensible to it. Alas, but can not completely withdraw them.
Therefore, synthetic vitamins are not absorbed because of their inferiority, and if they are assimilated, then only 1-5% (usually not more than 10%). What happens to the remaining 90%? A small part of the vitamin is excreted in the urine, and the rest is deposited in the liver, kidneys, joints, blood vessels, forming what we call slags. That is, artificial vitamins contribute to the fact that harmful (and sometimes even dangerous) chemicals accumulate in our body, which are almost not removed from the body. Hence, all the side effects of vitamins - it can be a hormonal failure, metabolic disorders, weakening of the immune system and the aggravation of certain diseases.
In my opinion, the conclusion suggests itself. Only from natural products we can and should receive everything necessary for our health. And there is no one that cannot be found in natural products. In addition, in addition to vitamins, plants contain minerals and thousands of other substances that are beneficial to the body - they are called “phytocomponents”. Therefore, when we eat vegetables, fruits, nuts, then we get the effect of the complex effect of all components of the plant on the body! There are no phytocomponents in synthetic vitamins, they are inferior. Therefore, it is impossible to predict with precision their health effects.
And, finally, the very quality of synthetic vitamins. Sad but true - they are NOT made from natural components of plant and animal origin. Oil, tar, bacteria, animal waste - these are the raw materials that underlie the production of vitamins in beautiful packages! The second turn of rotten tomatoes on the way! Now the network has such information that there are synthetic vitamins, but there are natural, and they need to be distinguished and bought the latest. In my opinion, natural - natural discord! For example me 
I have nothing against before
Higher animals cannot synthesize cobalamin (vitamin B12), they must receive this coenzyme from food. Animal products (liver, kidney, fish, eggs, milk) are its main sources.
A. Transport of cobalamin (B12)
Cobalamin biochemistry. Aqueous, or OH-cobalamin, is the precursor of two active forms, methyl- and adenosylcobalamin. Methylcobalamin is required for the formation of methionine from homocysteine; Cobalamin transfers the methyl group required for this type of N5-methyltetrahydrofolate (see below) to homocysteine. Some enzymes, such as methylmalonyl-CoA mutase, need adenosylcobalamin for breaking and forming carbon-carbon bonds.
Cobalamin - These are relatively large hydrophilic molecules that are required by transport proteins (A). During passage through the gastrointestinal tract, blood plasma, and other compartments, cobalamin binds to (1) internal factor (IF), which is secreted by the lining cells of the stomach; (2) transcobalamin II (TC II) in plasma; (3) R-proteins in plasma (TC I) and granulocytes (TC III), saliva, bile, milk, etc. Gastric acid releases cobalamin from food proteins. In most cases, cobalamin binds to R-proteins in saliva or (at high pH) with IF (A1). R-proteins are digested in the duodenum under the action of trypsin, which leads to the release of cobalamin, which is then connected to the (trypsin-resistant) internal factor (IF). In the terminal part of the ileum, the mucous membrane has highly specific receptors for the cobalamin-IF complex. TC II binds to these receptors and is absorbed by receptor-mediated endocytosis, provided that the pH is\u003e 5.6 and the availability of Ca2 + ions (A2). The density of receptors, and therefore the rate of absorption increases during pregnancy. Cobalamin binds to TCI, II and III in plasma (AZ). TC II mainly distributes cobalamin into all cells that undergo division (TC II receptors, endocytosis). TC III (from granulocytes) transports an excess of cobalamin and undesirable cobalamin derivatives to the liver (TC III receptors), where they are either stored or excreted in bile. The half-life of TS I, which serves as a short-term cobalamin depot in plasma, is about 10 days.
A vegan diet or impaired absorption of cobalamin can lead to severe deficiency symptoms, such as pernicious anemia (= B-12-folate deficiency) and spinal cord damage (funicular myelosis). It takes years for the development of these symptoms, because the body has a reserve that is 1000 times greater than daily needs (1 μg).
B. Absorption of folic acid
Folic acid / folate (= pteroylglutamic acid). N5, N10-methylenetetrahydrofolate, a metabolically active form of folic acid (daily need is 0.1-0.2 mg), is required for DNA synthesis (formation of deoxythymidylate from deoxyuridylate). Food folate usually contains up to seven glutamine residues (y-linked peptide chain: Pte-Glu7) instead of pteroylglutamic acid
