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

Ashwagandha KSM-66® Extract (12:1) from EssentialSeries is a food supplement made with ashwagandha root extract.

Ashwagandha is a Sanskrit term used to refer to Withania somnifera, also known as Indian ginseng. It has traditionally been used in India by people with a predominantly vata dosha (Health Canada, 2019).

This product is suitable for vegan diets.

Properties of Withania somnifera (Ashwagandha)

 Ashwagandha:

  •  Has an overall rejuvenating effect.
  •  Improves the body's resistance to stress.
  •  Helps maintain mental balance.
  •  Supports falling asleep.
  •  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, and physical and mental well-being.
  •  Contributes to emotional balance and overall well-being.

Why buy Ashwagandha KSM-66® from HSN?

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

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

  •  Water extraction, without alcohol: a water-based process that doesn't use alcohol as a solvent.
  •  Root only, no leaves: made exclusively from the root of Withania somnifera, the part of the plant traditionally used.
  •  Full spectrum: the process is designed to maintain the balance of compounds characteristic of the root, with a standardised content of 5 % withanolides.

A choice for anyone looking for a patented-brand root extract with a defined extraction process and a full-spectrum profile. Plus, the version we use at HSN is suitable for vegan diets.

Pure KSM-66®

Our KSM-66® ashwagandha extract is made exclusively with the raw material from Ixoreal Biomed Inc., the sole manufacturer of this internationally renowned registered brand.

We don't use any other ashwagandha in our product. It's 100 % KSM-66®, guaranteed.

KSM-66® is made exclusively from a carefully selected range of the largest Withania somnifera roots, as their quality research identifies these as desirable parts of the plant.

They don't use leaves or the smallest root sections.

The entire growing and harvesting process takes place in the Indian state of Rajasthan, where the climate and arid soil provide optimal conditions for growing top-quality, authentic Indian ginseng.

14 years of research

Developing KSM-66® took no less than 14 years of research and development to refine the patented process Ixoreal uses to produce its renowned raw material.

Although the extract is standardised to 5 % withanolides, it is considered 'full-spectrum'.

Ixoreal explains that a 'full-spectrum extract' is ideal because most scientific research uses ashwagandha roots that maintain a balance between the plant's characteristic chemical constituents. According to the manufacturer, producing an extract with an extremely high percentage of withanolides may upset the balance of its natural compounds.

The KSM-66® extraction process is based on 'green chemistry' (green chemical), as its patented extraction method uses no chemical solvents or alcohol.

KSM-66® is a raw material backed by a large number of scientific studies.

Ixoreal Biomed states that no fewer than 22 high-quality human clinical trials have used KSM-66® to assess the effects of ashwagandha.

Free from Withaferin A. Verified by HPLC

KSM-66® contains no Withaferin A, a type of withanolide that Ixoreal considers important to remove for reasons supported by its research.

The virtually absent Withaferin A and guaranteed 5 % withanolide content have been verified using high-performance liquid chromatography (HPLC), rather than gravimetry, which other manufacturers use to measure the extract's constituents. According to Ixoreal, gravimetry can overestimate a product's withanolide content by up to three times.

Certifications and awards

Ixoreal holds 24 quality certifications that attest to its good manufacturing practices.

For its outstanding performance, KSM-66® has received prestigious innovation and quality awards around the world throughout its time on the market.

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

Ixoreal produces 2 types of KSM-66®:

  •  Vegan and allergen-free.
  •  Non-vegan and containing a milk allergen.

Our product contains none of the allergens listed under 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.

Ashwagandha extract KSM-66® (12:1) 300mg

Good.

I’ve tried powder and gummies from other brands, but capsules are the best option. They have no taste, so they’re not unpleasant to take.

He probado de otras marcas en polvo o en gominolas y en cápsulas es la mejor opción. No tiene sabor por lo que no es desagradable

Ashwagandha KSM66

You can tell they use the original standardised KSM-66® extract, not just any root powder with no real active compounds. I mainly use it to reduce stress and cortisol. Great value for the number of capsules, strength per serving and price.

Se nota que utilizan la patente original KSM-66 estandarizada y no polvo de raíz cualquiera sin principio activo real. La uso sobre todo para bajar el estrés y el cortisol. Muy buena relación entre cantidad de cápsulas, concentración por toma y precio.
