In addition to what is posted on Dr. Clarks recipe I found this online;
Ornithine induces the release of growth hormones in the body, which in turn helps with fat metabolism. It is further required for a properly functioning immune system and liver and assists in ammonia detoxification and liver rejuvenation.
Since the body can produce ornithine, a deficiency of this non-essential amino acid is rare.
Somewhere along the line I read that parasite die-off releases ammonia. Maybe the high ammonia levels interfer with sleep and since this detoxifies the ammonia that helps you sleep ?
I really don't think it's meant (and in my search I couldn't find anything indicating) it's meant to be used as a "sleep aid" other than when cleansing.
I'm curious as to what others have to say about this.
