Significant reduction in levels of cortisol—the body’s primary stress hormone

One study showed that individuals taking 600 mg of KSM-66 saw a significant reduction in levels of cortisol—the body’s primary stress hormone—and fewer feelings of stress. Individuals were then given well-recognized psychological questionnaire tests to measure the effect of KSM-66. Test scores showed a significant improvement in stress and anxiousness plus an improvement in associated sleep quality.1

Another study showed that compared to a placebo, a 600 mg daily dosage of KSM-66 ashwagandha for a period of 8 weeks improved immediate, working, and general memory function along with measures of executive function, attention, and information processing.2 You get the same 600 mg research dose in Clinical Strength Ashwagandha.

Science and Quality

KSM-66 ® Ashwagandha

Ashwagandha, or Withania somnifera, is commonly known as “Indian winter cherry” or “Indian ginseng.” Ashwagandha is widely utilized in Ayurvedic medicine in India, and is deemed an “adaptogen,” an herb that protects the body from stress and helps the body address the effects of stress. Ashwagandha is widespread in many geographical locations including India, Pakistan, Morocco, Spain, and South Africa.

The beneficial effects of ashwagandha come from the complex synergy of all its natural constituents and KSM-66 is a full-spectrum root-only extract, retaining all the natural constituents.

In a double-blind, randomized, placebo-controlled trial, subjects taking KSM-66 saw a significant reduction in levels of cortisol—a primary stress hormone—after 60 days, while placebo saw an insignificant reduction. Subjects were then given well-recognized psychological questionnaire tests to measure the effect of KSM-66. Test scores showed a significant reduction in stress and a tremendous reduction in anxiousness! 1

In a prospective, double-blind, randomized placebo-controlled trial, 50 healthy athletic adults received either 600 mg/d (300 mg twice daily) of KSM-66 or placebo over 12 weeks to evaluate the efficacy of KSM-66 on cardiorespiratory endurance and quality of life. Data was collected at baseline and on days 28, 56, and 84. 2

  • Cardiorespiratory endurance (VO2 max measures translated from 20-meter shuttle run): VO2 max as measurement determines an athlete's ability to take in, transport, and utilize oxygen.
  • KSM-66 resulted in a significant increase in maximum oxygen consumption (VO2 max) at Day 56 and Day 84 as compared to baseline.
  • KSM-66 was able to help support cardiorespiratory performance in healthy adults while helping to improve their perception of their quality of life.

In another double-blind, placebo-controlled trial, female participants between the ages of 21–50 were given either a placebo or 600 mg of KSM-66 ashwagandha. After 8 weeks, the KSM-66 ashwagandha was clinically seen to improve sexual function and feelings to enhance sexual health. 3
