Description
Summary:[...]citrulline supplementation appears to be more effective in increasing plasma arginine concentration than the ingestion of arginine itself. 1 Citrulline is also an intermediate in the urea cycle, an important pathway that removes ammonia from muscle and liver cells. [...]it was recently proposed that free radicals may have useful functions in the body, particularly in the signalling pathways associated with exercise stimulus. [...]free radical production may be a prerequisite for training effects in muscle. 4 Some studies 5 6 report that chronic Q10 supplementation enhances exercise capacity or performance, whereas others do not. 7 - 9 There is also evidence that Q10 supplementation may interfere with adaptation to exercise.
