How To Get The Most Out Of Herbal Products

Herbal products are a mainstay of many health programmes but as with any supplement, it’s the quality of the active ingredient that will ensure you are not simply wasting your money on placebo pills. Ashwagandha is a good example: this flagship herb of Ayurvedic medicine has been used for centuries as an adaptogen, supporting balance and harmony in different hormone systems and the immune system to reduce stress, increase resilience and resistance to “burn out” and promote a calmer and happier sense of being. But, do you know what’s in your Ashwagandha product and does the extract you take or recommend have enough bioactivity to be clinically effective?

Ashwagandha root extract is packed full of different beneficial phytonutrients including withanolides, iron, choline, short and long-chain amino acids, fructo-oligosaccharides, Vitamin A, calcium, flavonoids, glucosides, coumarins and phytosterols. These synergistic compounds are not found at bioactive levels within the leaves of the plant, so already some products containing Ashwagandha leaves will not have the same levels of clinical efficacy (if any) compared to root extracts.

KSM-66 Ashwagandha is an organically grown, branded, full-spectrum extract, with the highest concentration of all major root-only extracts (including 5% withanolides) available on the market today. It is produced using a unique proprietary extraction process, based on “Green Chemistry” principles, without using alcohol or any other chemical solvent.

KSM-66 is an industry leader having been evaluated in 22 “Gold Standard” human clinical trials.

KSM-66 Ashwagandha has been clinically proven to help:

  • Reduce stress, anxiety, cortisol levels and stress-related food cravings.
  • Promote enhanced memory and cognitive function.
  • Promote endurance, strength, muscle size and muscle recovery rate.
  • Enhance sexual performance health in both men and women, and testosterone in men.
