Vitamin D2 Reliable Sources

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. Vitamin 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-?,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.
