Hygain Fast Twitch is a potent blend of nutrients and anti-oxidants to normalise glycogen storage and mitochondria generation in fast twitch oxidative fibres. As horses progress (during a preparation) from paddock condition to race fitness, muscle fibres must adapt to the increasing demands made on them. When work steps up to 3/4 pace, Fast twitch oxidative fibres are recruited to provide the power. As with other body tissues these muscle fibres must be trained to enable them to store glycogen and to generate more mitochondria (the powerhouses of the muscle cell) to use glycogen. If the work rate gets too far ahead of mitochondria production, muscles may lose suppleness. 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. F
