Vitamin D2, D3 / Ergocalciferol, Calciferol /

Sources of Vitamin D2

Rich of vitamin foods are: fish oil, liver, eggs, milk, butter, meat foods. The people, which train bodybuilding, have to take vitamin D together with the calcium preparations.

Vitamin d2 vs. d3

The vitamin D activity has significant role in calcium and phosphor metabolism, by regulating the calcium indraughts and transport trough guts, also transforms the organic form of the phosphor in inorganic, which is the suitable form in which phosphor precipitates in the body bones. The simultaneous calcium and vitamin D resorbtion improves by the middle-sized chain triglycerides taking, which normally contains in the milk butter. That is exactly the consummation of milk products contributes to the more effective calcium precipitation. In this case the triglyceride metabolism regulates from the paratohormone and calcitonin.

Vitamin D2 and vitamin D3 have almost equal vitamin activity, but vitamin D3 has more important key role. The primary vitamin D3 transformation begins in the liver, after that in the kidneys, bone cells, blood, placenta, etc. and in a result obtains the physiological form 1-α,25-dihydroxycalciferol. The latter substance synthesis has been regulating from the calcium blood level by the negative converse response- i.e the newly develop concentration stops its own synthesis. Besides in calcium metabolism participation, vitamin D3 takes part and in other processes such as immune response, myocardial metabolism, insulin secretion, spermatogenesis, etc. That is why has been puts down to vitamin D3 hormone activity.

Vitamin D deficiency slows down the bone calcification (rachitis, osteomalacia), decreases the carbohydrate and phosphate groups connection rate and the oxygen assimilation availability by mitochondria, too. The vitamin D deficiency is not recommended for these, which actively trained, because decreases the glycogen conversion into glucose-6-phosphat and by this way slows down the energy emission. The vitamin D deficiency also leads to kidney enzymes activity disturbance. The result appears in intense leucine, isoleucine, valin and histidin secretion in the urin.

Vitamin C is one of the most important vitamins in our body. It is found in a lot of foods, but mostly in fruits and vegetables (citrus fruits, tomatoes and green seasonings). When such foods missing in your diet, or are in small amounts, you can use vitamin C as a preparation.

Facts and benefits of vitamin C

Vitamin C has very significant functions in our body. Those are the most important: strengthens the bones, connective tissues and immune system, quickens the sore healing, actively participates in the body metabolism and acts like an antioxidant. Vitamin C defenses the body liquids (mainly blood) from the free radicals function. The vitamin also strengthens the blood vessels, which leads to blood pressure stabilization. It has prophylactic activity at cancer, cardio-vascular and arthritis diseases and delays the growing older processes too. According to some experiments vitamin C suppresses the cortisol secretion, who takes down the fence of the muscular tissue. This activity increases the testosterone/cortisol proportion, which stimulates the muscle growth.

The minimum vitamin C dose for people which do not sport regularly is about 100 mg. daily. For sporting people the recommended dose is bigger: 300-800 mg. Vitamin C is not dangerous even in huge doses, because the redundant amount removes form the body with the urine (but still in this case you have to drink a lot of water, otherwise the glomeruly kidneys can be damaged). The people with diabetes have to be careful with the vitamin C high doses, because it suppresses the normal function of the pancreas and by this way reacts directly upon insulin levels.

All multivitamins contain vitamin C (MultiTabs, Supradin, Supravit, etc.) and also can be sell as separate tablet.

Description and sources

When folic acid enters the body it moves to liver where becomes biologically active. Vitamin B12 and vitamin C are co-operating the converting process. That is why the folic acid biological activity depends from the levels of the vitamin B12 and vitamin C in the body. Here are listed in a descending line some folacin sources: liver, parsley, spinach, green salad, mushrooms, peas, meat, fish, etc. Vitamin B9 is very sensitive to thermal treating and oxidizes very easy from the air oxygen.

General descriptions :

The folic acid participates in amino acid and nucleic acid metabolism. Besides has a big hematopoietic potential and assists the red blood maturation in the marrow. Folacin deficiency occurs with the megaloblastic anemia development (red blood cells deficiency). Folic acid luck develops also at alcoholism, because the alcohol suppresses the vitamin B9 activity. Frequently folacin deficiency occurs in pregnant women and in people which regularly takes drugs, such as antibaby pills. People with liver disease have raised folacin needs. At prolonged sun expose an extra dose of the vitamin B9 is needed, because the sun light destroys it.
