Ashwagandha (Withania somnifera) has been used in Ayurvedic medicine for over 3,000 years, but modern science is only now catching up with what traditional practitioners have long known. This adaptogenic herb has become one of the most researched botanicals of the decade.
What Makes KSM-66 Special
KSM-66 is a patented, full-spectrum ashwagandha root extract produced using a unique extraction process that preserves the natural balance of constituents. It is backed by 24 gold-standard clinical trials — more than any other ashwagandha extract — demonstrating benefits for stress reduction, cognitive function, endurance, and sleep quality.
Stress and Cortisol
One of ashwagandha’s most well-documented effects is its ability to modulate cortisol, the body’s primary stress hormone. Clinical studies have shown that KSM-66 supplementation can reduce cortisol levels by up to 30%, leading to measurable improvements in perceived stress, anxiety, and sleep quality.
For best results, consistency is key. Most studies show benefits emerging after 4-8 weeks of daily supplementation with 600mg of KSM-66 root extract.
