i found this so it appears Malate is a good addition:
[FONT="]Malate facilitates a process called anaplerosis which is the act of replenishing component parts of the tricarboxyic acid cycle- also known as the Kreb cycle. This is a key component of aerobic respiration and how we gain energy from the use of oxygen.[/FONT]
[FONT="]Malate will influence certain anaplerotic reactions and reduce the block of the oxidative energy pathway caused by excess ammonia. It then uses lactic acid formed as a byproduct of exercise to form more pyruvate. With more efficiency of aerobic metabolism, we are then able to create more adenosine triphosphate (ATP- energy!)- hence reducing fatigue![/FONT]
[FONT="]In fact, upon testing, significantly more aerobically produced ATP is generated when CM is provided, showing an enhancement of oxidative processes(4). This study also showed significantly faster phosphocreatine level recovery following exercise and levels of both muscle PH and power were both sustained at a higher level- indicating a decreased rate of ATP formed through anaerobic metabolism.[/FONT]
[FONT="]Other plasma and muscle changes following exercise with CM supplementation include higher levels of insulin; more efficient use of branch chain amino acids during exercise; and facilitation of greater increases of growth hormone(22).[/FONT]
