(2) Serving as the substrate for glutathione peroxidase enzymes, which reduce peroxides to water
Nerve repair protocols typically require 4-8 weeks of consistent use
Research in humans is a bit less impressive Clinical trials in humans A 1981 double-blind study found that chronic insomniac patients found that subjects slept 59% more, shorter sleep latency, and higher sleep efficiency (Schneider 1981) A 1987 double-blind study did not find any statistically significant changes in sleep structure as measured by REM sleep, NREM sleep, or total sleep time (Debellis 1987) A 1992 double-blind study in 14 chronic insomnia patients found higher sleep efficiency and subjectively estimated tiredness decreased to similar levels of healthy subjects in 7 nights of injections (Schneider 1992) There are some limitations to these studies however
Glucose tolerance tests (GTT) and insulin tolerance tests (ITT) were performed ( n = 12 per group, per sex) to assess glucose metabolism and insulin sensitivity 46
