E.S.tong
Composition
Each ml contains:
Vitamin E 68 mg
Sodium Selenite 1.5 mg
Description
It is a milky white emulsion liquid.
Pharmacology
Vitamin E: It is an antioxidant and is necessary for the stability and function of muscle tissues. It has a similar role to selenium and each can, to some extent, replace the other.
Selenium: The essential role of selenium is as part of the enzyme glutathione peroxidase, whose function is to prevent free-radical damage to tissue.
There is a complex interaction between the requirements of selenium and vitamin E whereby either may substitute in part for the other. A deficiency is most frequently seen in young, fast growing animals, causing degeneration of cardiac, respiratory and skeletal muscles and neurone degeneration in horses.
