SIS GO IMMUNE Gel - 30 Pack

SIS GO IMMUNE Gel - 30 Pack • High strength fruit extract with a unique vitamin and mineral blend to support immune function. • Unique ‘dual action’ patent pending immune formulation • Perfect for use in training and racing, especially in bad weather. • Great tasting gel with 22g carbohydrate to fuel performance • Drug screened as part of the Informed Sport program. Background: The GO Energy + Immune gel is one of the most exciting and innovative sports nutrition products available. It was developed in response to athlete requests for a safe, effective supplement that could be taken every day to help maintain immune function. It is well known that intense exercise increases the body’s exposure to harmful bacteria and viruses, while simultaneously suppressing immune system functioning. These effects can contribute to a high incidence of gastrointestinal issues in athletes, disrupting training and ultimately compromising performance. Who it’s for: The GO Energy + Immune gel was developed specifically at the request of athletes who wanted to minimise problems associated with impaired immune function. Despite this, GO Energy + Immune gels are also perfect for anyone who is physically active and wants to maintain immune system functioning. How and when to use GO Energy + Immune – gels: The versatility of GO Energy + Immune gels allow them to be used in a range of race and training situations: • During training or races to contribute to the normal functioning of the immune system, while also fuelling performance. • During flights to help maintain normal immune system functioning, while also helping hydration. • In cold weather, wet weather, or at altitude. The GO Energy + Immune gel should ideally be taken after drinking, although like all SiS gels their unique consistency means there is no need for additional water. Due to the high strength ingredients in GO Energy + Immune gels, no more than 2 per day should be consumed.

SIS Go Energy & Protein Bar - Box (24 Bars)

GO Energy + Protein Bars are a nutritious, easily digestible high carbohydrate and protein based snack; made from fruits, wholesome ingredients and soy protein isolate. Delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue; while protein contributes to the growth and maintenance of muscle mass. Benefits of Science in Sport GO Energy + Protein Bar This nutritious snack can be used to increase the daily carbohydrate content of an athlete’s diet and taken during exercise can contribute to fuelling performance. Proven by thousands of athletes in the world's toughest races, it meets their demanding energy needs. Depleting your carbohydrate stores during exercise is one of the major causes of fatigue, additional carbohydrate is essential to maintain performance. Evidence is now suggesting that endurance athletes should also consume protein, in addition to carbohydrate, during exercise so as to prevent the protein breakdown (and hence promote better training adaptation) that occurs during prolonged exercise of moderate to high-intensity. It is also advised that protein is consumed within 60 minutes prior to endurance exercise. Our complete product range is developed using a world-class approach to banned substance testing, providing assurance for athletes. Recommended Usage GO Energy + Protein Bar can be used during exercise to meet fuelling requirements, before endurance exercise as a high carbohydrate, high protein option or as a daily snack to meet carbohydrate and protein requirements. RRP: £1.50 Suitable for: Vegetarians; Nut Free; Lactose Free
