What is the Ashwagandha Extract KSM-66® (12:1)?

Ashwagandha Extract KSM-66® (12:1) from EssentialSeries is a dietary supplement based on the root extract of ashwagandha.

Ashwagandha is a Sanskrit term, popularizing the Withania somnifera, also known as Indian Ginseng, since it has traditionally been used in this region with people of predominantly vata dosha (Health Canada, 2019).

This is a product suitable for vegan diets.

Properties of Withania somnifera (Ashwagandha)

 The ashwagandha:

  •  Has a general rejuvenating effect.
  •  Improves the body’s resistance to stress.
  •  Helps maintain mental balance.
  •  Supports the onset of sleep.
  •  Supports learning, memory and recall.
  •  Has adaptogenic properties.
  •  Supports male sexual function.
  •  Helps maintain energy levels.
  •  Helps maintain optimal endurance, feelings of energy and vitality, physical and mental well-being.
  •  Contributes to emotional balance and overall well-being.

Why buy Ashwagandha KSM-66® at HSN?

KSM-66®: water extraction, only root and full spectrum

At HSN we choose KSM-66® for its extraction process and composition profile. Here are the three keys to know it at a glance:

  •  Water extraction, no alcohols: a aqueous process that doesn’t use alcohols as solvents.
  •  Only root, no leaves: made exclusively from the root of Withania somnifera, the part of the plant traditionally used.
  •  Full spectrum: its process is designed to maintain balance among the characteristic root compounds, with a standardized content of 5% withanolides.

A choice for those seeking a patented‑brand root extract, with a defined extraction process and a full spectrum profile. Plus, the version we use at HSN is vegan-friendly.

ExtractKey characteristicsChoose if...

Pure KSM-66®

Our Ashwagandha extract KSM-66® is made exclusively from Ixoreal Biomed Inc.’s raw material, the sole manufacturer of the internationally recognized brand.

We don’t use other ashwagandas as part of the product’s composition, it’s 100% KSM-66®, guaranteed.

The KSM-66® is made exclusively from a careful selection of the larger roots of the Withania somnifera, as their quality studies show these are the desirable plant parts.

No leaves or the smaller root fractions are used.

All the cultivation and harvest is done in the Indian state of Rajasthan, where climate and acidic soil conditions are optimal for growing the highest quality authentic Indian Ginseng.

14 Years of Research

The development of KSM-66® required no less than 14 years of research and development to refine the patented process Ixoreal uses to obtain its famous and reputed raw material.

The extract is characterized by, despite being standardized to 5% withanolides, being a “full-spectrum.”

Ixoreal explains that the “full-spectrum extract” is ideal, as most scientific research is conducted with Ashwagandha roots that maintain a balance among the plant’s characteristic chemical constituents. Obtaining an extract with an extremely high percentage of withanolides, according to the manufacturer, can cause the balance of substances to be lost.

The KSM-66® extraction process is based on “green chemistry” (green chemical), since its patented extraction procedure is developed without chemical solvents or alcohol.

KSM-66® is a raw material with a large amount of scientific studies backing its use.

Ixoreal Biomed states that no fewer than 22 human clinical trials, with the highest methodological quality, use KSM-66® to evaluate the effects of the study on ashwyandha use.

Witaferin A free. Validated by HPLC

KSM-66® does not contain Withaferin A, a type of withanolide that Ixoreal considers relevant to remove for justified reasons in the studies they have conducted.

The practically nonexistent presence of Withaferin A and the 5% withanolide content guaranteed have been verified by high-performance liquid chromatography (HPLC) rather than gravimetry as other manufacturers use to measure extract constituents, since, according to Ixoreal, gravimetry overestimates the product’s withanolide content by up to three times.

Certificates and awards

Ixoreal holds 24 quality certificates guaranteeing good manufacturing practices.

For its great performance, KSM-66® has received renowned innovation and quality awards worldwide throughout its market history.

Our version of KSM-66® is vegan. But not all of it is.

Ixoreal produces 2 types of KSM-66®:

  •  Vegan and allergen-free.
  •  Non-vegan and with milk allergen.

Our product contains no allergens listed by EU Regulation 1169/2011; and is 100% suitable for vegan diets.

A critical customer says:

Easy to swallow pending prolonged consumption

Ignacio | 15/05/2025

I have been using the product for a short time. I have not noticed any noticeable results so far, I imagine because it will take more time consuming it. The size of the tablet is small and easy to swallow.

Llevo poco tiempo utilizando el producto. No he notado de momento resultados reseñables, imagino porque hará falta llevar más tiempo consumiéndolo. El tamaño de la pastilla es pequeño y fácil de tragar.
