The Complete Formula Endura Optimizer is a patented, easy-to-digest, liquid meal to fuel race and recovery. A balanced ratio of protein, carbohydrates and rapidly absorbed amino acid peptides, Endura Optimizer is a superb source of metabolic fuel for working muscles and other tissues. Ideal Ratio of Carbs to Protein Endura Optimizer combines carbs with a pure, enzymatically hydrolysed whey protein, the highest biological value (BV) protein available, in a 6:1 ratio. This is most efficient way of replenishing glycogen stores, allowing the body to use the carbohydrates as a source of fuel, thus conserving muscle mass. Endura Optimizer contains a specially balanced blend of high performance branched-chain glucose polymers and pure crystalline fructose. These multiple energy sources are metabolised at different rates, resulting in a steady stream of nutrients being supplied to the bloodstream for prolonged periods after consumption. This greatly enhances endurance and helps stabilise blood sugar levels.
