Is Ornithine Exercise Fatigue Randomized Trial safe?

Updated October 2026

Quick Answer

Ornithine Exercise Fatigue 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: Purpose This study examined the effects of acute and chronic oral intake of tea catechins and ornithine supplementation on exercise-induced ammonia accumulation and cycling performance.

Key Takeaways

  • 01Purpose This study examined the effects of acute and chronic oral intake of tea catechins and ornithine supplementation on exercise-induced ammonia accumulation and cycling performance. [Nagayama C (2025)]
  • 02Methods Sixteen healthy young men participated in a randomized, double-blind, cross-over, placebo-controlled study. [Nagayama C (2025)]
  • 03Compared with traditional data-dependent acquisition (DDA) approaches, Zeno SWATH-DIA provided enhanced metabolite coverage, improved reproducibility, and reduced precursor selection bias (a statement of quantitation of how much more). [Hashmi MA (2026)]
  • 04Saliva is an accessible, noninvasive biofluid for real-time monitoring of physiological and metabolic changes. [Hashmi MA (2026)]
The current Migaku evidence database contains 2 reusable source documents for Ornithine Exercise Fatigue Randomized Trial. This answer focuses on safety, limits, and clinician-discussion contexts. - Purpose This study examined the effects of acute and chronic oral intake of tea catechins and ornithine supplementation on exercise-induced ammonia accumulation and cycling performance. [Nagayama C (2025); evidence level 2] - Methods Sixteen healthy young men participated in a randomized, double-blind, cross-over, placebo-controlled study. [Nagayama C (2025); evidence level 2] - Compared with traditional data-dependent acquisition (DDA) approaches, Zeno SWATH-DIA provided enhanced metabolite coverage, improved reproducibility, and reduced precursor selection bias (a statement of quantitation of how much more). [Hashmi MA (2026); evidence level 4] - Saliva is an accessible, noninvasive biofluid for real-time monitoring of physiological and metabolic changes. [Hashmi MA (2026); evidence level 4] - However, its potential to capture physical-exciton-induced biochemical responses has been limited by the metabolite identification depth and reproducibility of conventional metabolomics tools. [Hashmi MA (2026); evidence level 4] 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. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
