A preliminary study involving physically active male college students suggested that daily supplementation with American ginseng for 4 weeks prior to high-intensity exercise did not enhance aerobic workout capacity. However, creatine kinase levels, which are an indicator of muscle damage, were lower in the group taking American ginseng compared to a placebo.[1] It's important to note that this study had a small sample size of only 13 participants.
