Peak athletic performance requires strong, healthy muscles. Ultra E Greyhound Muscle Supplement provides a blend of Vitamin E and organic Selenium to ensure optimum muscle health and nutrition. Best used in conjunction with PerformAid. Selenium and Vitamin E are the two major anti-oxidants which neutralise toxic free radicals. They work together to quickly neutralise these toxic by-products produced during the oxidation process. Selenium exerts its effect inside the muscle cells, while Vitamin E protects the cell membranes. Performance greyhounds require greater amounts of anti-oxidant nutrients in order to combat the very high level of toxic free radicals produced during intense exercise. Ultra-E-Greyhound-Muscle-Supplement-Group Ultra E greyhound Muscle Supplement can compensate for anti-oxidants that are not usually provided by feed alone.
