Why buy Ashwagandha KSM-66®️ at HSN?
Pure KSM-66®️
Our ashwagandha extract KSM-66® is made solely and exclusively with raw material from Ixoreal Biomed Inc., the only manufacturer of the internationally renowned registered brand.

We don’t use other ashwagandhas in our product, it’s 100% KSM-66®, guaranteed.
100% Root
KSM-66® is made exclusively from a careful selection of the largest roots of Withania somnifera, since according to their quality research, these are the desirable parts of the plant.
They don’t use leaves or the smaller root fractions.
The entire cultivation and harvesting process takes place in the Indian state of Rajasthan, where the arid soil and climate conditions are optimal for growing the highest quality authentic Indian Ginseng.
14 years of research
The development of KSM-66® took no less than 14 years of research and development to refine the patented process Ixoreal uses to obtain its famous and reputable raw material.
The extract is characterized by being standardized to 5% withanolides, yet it is considered a 'full-spectrum'.
Ixoreal explains that the 'full-spectrum extract' is ideal, since most scientific research is done with ashwagandha roots that maintain a balance between the plant’s characteristic chemical constituents. Obtaining an extract with an extremely high % of withanolides can, according to the manufacturer, cause the loss of the plant’s natural substance balance.
The extraction process of KSM-66® is based on 'green chemistry' (green chemical), as its patented extraction procedure is carried out without using chemical solvents or alcohol.
Extensive research
KSM-66® is a raw material backed by a large number of scientific studies supporting its use.
Ixoreal Biomed states that no less than 22 human clinical trials, with the highest methodological quality, use KSM-66® to evaluate the effects of ashwagandha in their studies.
No Withaferin A. Validated by HPLC
KSM-66® contains no Withaferin A, a type of withanolide that Ixoreal considers important to eliminate for reasons justified in their studies.
The practically nonexistent presence of Withaferin A and the guaranteed 5% withanolides content have been verified by high-performance liquid chromatography (HPLC) instead of gravimetry as other manufacturers do to measure extract constituents, since according to Ixoreal, gravimetry overestimates the withanolides content by up to 3 times.
Certificates and awards
Ixoreal holds 24 quality certificates that guarantee its good manufacturing practices.
Due to its outstanding performance, KSM-66® has received prestigious innovation and quality awards worldwide throughout its years on the market.
Vegan
Our version of KSM-66® is vegan. But not all are.
Ixoreal produces 2 types of KSM-66®:
- Vegan and allergen-free.
- Non-vegan and containing milk allergen.
Our product contains no allergens listed under EU regulation 1169/2011; and is 100% suitable for vegan diets.
