Effect of E-OJ-01 on Left Ventricular Ejection Fraction and Myocardial Oxygen Consumption: A Randomized, Double-Blind, Placebo-Controlled Study
Overview
Affiliations
Purpose: E-OJ-01 (Oxyjun), a proprietary, standardized aqueous extract of (TA) bark, has previously shown promising cardiovascular health benefits in healthy young athletic adults and is now being tested to determine its ability to support left ventricular ejection fraction and associated parameters in a diverse population.
Participants And Methods: Healthy adults aged 30-70 years (n=72) were included in the study to investigate the effect of 400 mg/day of E-OJ-01 when administered for 8 weeks on myocardial pumping capacity, primarily left ventricular ejection fraction (LVEF). The secondary endpoints were improvement in diastolic filling (E/A) ratio, rate pressure product (RPP), and fatigue severity scale (FSS) score. The effect of the intervention on blood lipids and gamma-glutamyltransferase (GGT) levels was also explored. The safety of the intervention was evaluated by monitoring adverse events, vitals (heart rate (HR), blood pressure (BP), and body temperature (BT)), and liver (serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT)) and kidney function (serum creatinine).
Results: E-OJ-01 increased the LVEF by 6.28% (percentage change) from the baseline compared with 0.24% (percentage change) in the placebo group (p<0.05). It reduced fatigue (22.52%), RPP (1.54%), and GGT levels (5.90%) from the baseline. No adverse events related to the intervention were observed during the study.
Conclusion: The study showed that E-OJ-01 could improve cardiac pumping capacity by significantly increasing LVEF and reducing fatigue in a diverse, healthy population.
