A glucose disposal agent (GDA) works by mimicking the effects of insulin. This is a very powerful hormone that works to increase nutrient partitioning into the muscle cells. This is a huge advantage when looking to increase muscle recovery and performance.
Typically, these are best taken around training times to allow more nutrients to be driven into the trained body parts and speed up the recovery process.
In addition to being excellent for recovery these can also be excellent for fat loss as well. It does this by keeping blood glucose levels more stable creating a better environment for fat loss.
