Eleuthero: Eleuthero is an Asian herb that has long been compared to ginseng and has been ruled out as similar yet less potent. Nevertheless, herbalists have celebrated this ingredient as an adaptogen, meaning that it could protect the body from the effects of stress. Regarding research on its usefulness, the general consensus is that it could boost energy, metabolism, and physical performance, ease stress levels, and possibly regulate blood sugar levels. Unfortunately, most of these results are derived from animal studies, therefore requiring quality, human-focused research.
