Quick Answer
L-Ornithine Sleep Quality Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Although L-ornithine is contained in various foods, the amount is usually small.Recently, studies have shown that orally administered L-ornithine reduced the stress response in animals.From these findings, we speculated that L-ornithine may play a role in the relieve of stress and improve sleep and fatigue symptoms in humans.
Key Takeaways
- 01Although L-ornithine is contained in various foods, the amount is usually small.Recently, studies have shown that orally administered L-ornithine reduced the stress response in animals.From these findings, we speculated that L-ornithine may play a role in the relieve of stress and improve sleep and fatigue symptoms in humans.

- 02Also, anger was reduced and perceived sleep quality was improved in the L-ornithine group. [Miyake M (2014)]
- 03Conclusion L-ornithine supplementation has the potential to relieve stress and improve sleep quality related to fatigue, both objectively and subjectively. [Miyake M (2014)]
- 04Through a randomised, double-blind, placebo-controlled clinical study, we asked if L-ornithine could be beneficial to stress and sleep in healthy workers. [Miyake M (2014)]

Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
