Vitamite® Fast Twitch Formula™ provides specific nutrients to assist mitochondrial formation, anti-oxidant vitamins, selenium to enable glutathione peroxidase production and magnesium to address the metabolism imbalance caused by calcium flux on the muscle cell wall. For horses positive to the GYS1 gene (PSSM), feed a diet with almost no starch, e.g. Munga® and hay and add Fast Twitch Formula™ pellets. For best results, Vitamite® Fast Twitch Formula™ should be used in conjunction with an exercise program that maximises the use of the Fast Twitch Oxidative fibres.
