High 5 4:1 bar contains 4 parts carbohydrate (80%) & 1 part protein (20%). The carbohydrate in the 4:1 bar contains a mix of both simple sugars & complex carbohydrate from Oats. The protein in 4:1 is a combination of whey protein, soy & wheat gluten to provide a balance of amino acids & boost the glutamine content for post exercise recovery. 4:1 Bar is naturally flavoured using dried cranberries. The repair & growth of muscle tissue is critical for long-term improvements in all sports. This is because, less muscle damage during training & more rapid recovery afterwards translates to stronger, more resilient muscles, lower risk of picking up an injury & real fitness gains. Recent research has shown that compared to carbohydrate only consuming carbohydrate & protein during exercise lowered protein (muscle) breakdown rates by 26% & raised protein synthesis (muscle building) by 33%.
