Latest review conclusion

Based primarily on case reports ornithine levels can be reduced by using a protein restricted diet, pyridoxine supplementation (variation-dependent) and/or lysine supplementation. The lack of pre-defined clinical outcome measures and structural follow-up in all included studies impeded conclusions on clinical effectiveness. Future research should be aimed at 1) Unravelling the OAT biochemical pathway to identify other possible pathologic metabolites besides ornithine, 2) Pre-defining GACR specific clinical outcome measures, and 3) Establishing an international historical cohort.

“Finally, I started to take L-lysine for a different issue. Immediately I saw that I could lay my head down at night and go to sleep like I could before. That was several months ago and I continue to sleep regularly.”

Thymosin Alpha-1
Latest review conclusion

Based on the results of the included studies, there is insufficient evidence to support or refute the effectiveness of different interventions for avulsed and replanted permanent front teeth. The overall quality of existing evidence was very low, and therefore great caution should be exercised when generalising the results of the included trials. There is urgent need for further well-designed randomised controlled trials.

“I started peptide therapy a little over a month ago for traumatic brain injury. The results I've experienced have been tremendous. I'm getting brain function back that has been gone for over a decade.”
