Ashwagandha (Withania somnifera) has a long history of use as a foundational adaptogen in Ayurvedic medicine. It is widely recognized to have broad benefits, including increased resistance to stress and anxiety, enhanced physical performance and immune function, as well as improved fertility, sleep, and neurological function. Its diverse phytochemistry includes withanolides, sitoindosides, phenolics, and flavonoids, which help explain its diverse physiological actions, ranging from cardio- and neuroprotective effects, to anti-inflammatory and anxiolytic effects.
KSM-66 is a full-spectrum extract of ashwagandha that uses only the roots of the plant, notable for the extensive range of randomized and controlled trials documenting its efficacy. Clinical trials have demonstrated a significant improvement in both symptom scores and cortisol levels among participants with chronic stress, along with improved weight control and cravings in this population. It has also been shown to improve general well-being, sleep quality, and mental alertness in older adults, as well as memory and executive function in individuals with cognitive impairment. Clinical trials document an increase in cardiorespiratory endurance, measured by VO2 max, among male and female athletes using KSM-66, and greater increases in muscle mass and strength when coupled with resistance training. In addition, the KSM-66 extract has demonstrated benefits for increasing sleep quality, improving sexual function in men and women, restoring spermatogenic activity in oligospermic men, and enhancing thyroid function in individuals with subclinical hypothyroidism.
