Resveratrol is a wine phenolic that is known to interact with sirtuin proteins (mostly SIRT1) which is similar to leucine; the metabolites of KIC and HMB at are able to induce SIRT1 to 30-100% of baseline which is a comparable potency to 2-10μM resveratrol  although the combination of leucine () or HMB (μM) and resveratrol (200nM) is able to synergistically induce SIRT1 and SIRT3 activity in both adipocytes and skeletal muscle cells.  KIC appears to be a more potent stimulator than HMB,  and synergism appears to be greater with leucine than with HMB (possibly indicative of KIC metabolism). 
Glutamine is an amino acid that is found in your muscles. Research has shown that after an intense workout, the glutamine levels in your body can drop by as much as 50%. Glutamine is also essential to keep your immune system functioning properly. As we all know, a poor immune system can leave you feeling weak and sick. According to a study by Trinity and All Saints University College, a routine supplementation of glutamine post-workout can help lessen the change of injury, improve immune function and help you recover faster after over training. 2 grams of L-glutamine daily is all that you need.
