How Does Physician’s Choice KSM-66 Ashwagandha Work?
This supplement supports the body’s natural stress response and helps maintain physical and mental health balance. The key ingredient, ashwagandha, is an adaptogen that helps the body adapt to stress by regulating cortisol levels, the hormone responsible for stress. Lower cortisol levels may result in better focus, calmer moods, and improved energy.
Ashwagandha is also known for enhancing endurance and physical performance by improving oxygen use during exercise. This may help with better stamina and quicker recovery. Additionally, it supports well-being by promoting restful sleep, which is essential for managing stress and staying energized.
Ashwagandha has a positive effect on stress and physical performance. A study published in the Journal of the International Society of Sports Nutrition highlights its benefits for muscle recovery and endurance.
Key Ingredients of Physician’s Choice KSM-66 Ashwagandha – Are They Safe & Effective?
Here are its primary ingredients:
KSM-66 Organic Ashwagandha Root Extract
KSM-66 is a potent extract derived from the ashwagandha root known for its stress-reducing and adaptogenic properties. As highlighted in our WOWMD Ashwagandha Extra Strength Formula Review (another supplement containing this ingredient), it helps lower cortisol levels, improve focus, boost energy, and support better sleep. A study published in the Indian Journal of Psychological Medicine demonstrated its effectiveness in reducing stress and enhancing well-being.
Kapoor J states that findings suggest that high-concentration full-spectrum Ashwagandha root extract improves an individual’s resistance towards stress and thereby improves self-assessed quality of life.
Organic Black Pepper Extract (Piper nigrum)
Black pepper extract is included to enhance the absorption and effectiveness of the ashwagandha. Its active compound, piperine, improves bioavailability, ensuring the body can absorb and use the nutrients more effectively.
We see that other well-established supplements like WOWMD VitaSun K2+D3 use black pepper extract (BioPerine) to increase the bioavailability of other ingredients in their supplements.
Research published in the Journal of Nutrients highlights piperine’s ability to boost nutrient absorption and support health.
Dr.Diego Fernández-Lázaro, Professor in the Department of Cell Biology, Histology, and Pharmacology at the University of Valladolid, highlighted that Bioperine®, a bioavailability enhancer in the form of black pepper, could potentially be used as an athlete’s Fe supplement to improve hematological parameters.
