KSM-66 Ashwagandha Uses and Benefits

KSM-66 Ashwagandha is an organically grown, sustainable, transparent, socially responsible, full-spectrum withania somnifera, extracted exclusively from the Ashwagandha plant roots (rhizhome).

KSM-66 Ashwagandha is known for its adaptogenic properties that support normal, healthy, cognitive and physiological functions, especially in times of stress. It is therefore suitable for anyone who partakes in regular exercise or leads an active lifestyle.

In fact numerous clinical studies have evaluated KSM-66 Ashwagandha, specifically testing the full spectrum herbal withanolides as to their potential benefits on human health along with the associated physiological modes of effect.

As a result various strong lines of evidence consistently demonstrate KSM-66 Ashwagandha to elicit a whole manner of potential health benefits. Consequently, the applications of KSM-66 Ashwagandha are far reaching.

So far the data on KSM-66 Ashwagandha suggests a long list of potential health benefits that may include support for; stress & anxiety (1), testosterone (2), weight management (3), cardiovascular system (4), anti-aging (5), sleep (6), thyroid (7), and memory & cognition (8).

What is the difference between KSM-66 and Ashwagandha?

KSM-66 Ashwagandha goes above and beyond the potency of regular unbranded Ashwagandha due to a number of unique factors.

In the practice of traditional Ayurvedic medicine, it is believed that Ashwagandha’s ability to support health is due to the synergy between each of the many constituent nutrients, rather than being attributed to just one or two of the individual compounds.

The production of regular Ashwagandha powder does not adhere to any quality control standards that ensure full-spectrum potency, whereas KSM-66 Ashwagandha encompasses a full-spectrum of naturally occurring Withanolides extracted exclusively from the roots.

Thanks to a proprietary “green” extraction process which does not rely on alcohol or any other chemical solvents, KSM-66 Ashwagandha is able to maintain a full complement of not just Withanolides, but also, Saponnins, amino acids, Flavanoids, and other beneficial nutrients, including vitamin A and Choline.

Additionally, KSM-66 Ashwagandha is manufactured exclusively from the shrub’s roots whereas most other Ashwagandha supplements use the dried leaves. Using the root only assures the final Ashwagandha powder is free of the cytotoxic Withaferin A, which is abundant in the leaves and is undesirable due to its toxicity.

Finally, KSM-66 Ashwagandha is quality and potency assured as a result of advanced HPLC (High-performance liquid chromatography) laboratory testing that characterises each compound to ensure that a full-spectrum extract, with optimum Withanolide content is yielded.
