On May 13, 2022, a toxicity study Published by NNB (https://journals.sagepub.com/doi/abs/10.1177%2F10915818221094487) was designed to evaluate the safety and toxic potentials of MitoBurn(L-BAIBA), where L-BAIBA was administered orally to Sprague Dawley rats at 100, 300, and 900 mg/kg/day for 90 days. The study shows that no treatment-related adverse effects were observed in any of the treatment groups. Based on the results, the No-Observed-Adverse-Effect Level (NOAEL) of L-BAIBA was 900 mg/kg/day. This study is the first study to access the safety profile of L-BAIBA in an in vivo repeated dose subchronic toxicity stud by oral (gavage) route in Sprague Dawley rats.
