Dextrose is a high GI, fast absorbing – simple carbohydrate. It is used by bodybuilders and athletes to induce an insulin spike and replace glycogen in muscle cells which is lost during training.
Studies have shown that the optimal amount of dextrose needed to induce an insulin spike post workout is 60-75g.
Dextrose is particularly effective when mixed with creatine, whey protein and glutamine. The insulin spike created by dextrose will move nutrients from these other supplements into the muscle cells very fast.
