What is Ashwagandha?

Ashwagandha is a small shrub plant with yellow flowers that’s native to India and North Africa. Its botanical name is Withania somnifera, and is also known by several other names, including Indian ginseng and winter cherry. Ashwagandha is one of the most powerful herbs in Ayurvedic healing, a form of alternative medicine based on Indian principles of natural healing. Ashwagandha has been used for over 3,000 years to help relieve stress, increase energy levels, and improve concentration. 

What is KSM-66® Ashwagandha?

KSM-66® Ashwagandha is a peer-patented clinical based ingredient, created via a process that took 14 years of R&D to develop and refine. It is a branded full-spectrum root extract, with the highest percentage of withanolides (active compounds) compared to any other root-only extract, measuring over 5% by HPLC. A “full-spectrum" extract includes the highest percentage of all the plant's chemicals and compounds, without affecting the natural ratio of these constituents present in the plant. KSM-66® has the highest potency and bioavailability of Ashwagandha on the market today. It is the highest clinically studied version of Ashwagandha, supported with 22 gold standard human clinical trials, further proving its efficacy.  

Supplementing with KSM-66® Ashwagandha has been shown to reduce anxiety, fatigue, boost mood, enhance brain health and reduce inflammation. It is produced using a first of its kind unique extraction process, based on “Green Chemistry” principles, without using any synthetic solvents or alcohol. The producer of KSM-66® is the only Ashwagandha manufacturer in the world with their own farms, production facilities, testing laboratories, research centre and distribution.

    KSM 66 Ashwagandha root extract is used in our anxiety supplement Calm.

    The Issue with other Ashwagandha products?

    The Ashwagandha market is full with products containing the plants’ leaf compounds, which can have a negative effect on the body due to the high levels of toxicity. A number of Ashwagandha supplements have also been exposed to not contain the levels of validated compounds as suggested on the label, which jeopardises efficacy. Earths Secret guarantees 600mg of KSM-66® Ashwagandha inside each daily dose. This is the optimal dose for ultimate efficacy.

    Why we use KSM-66® Ashwagandha in our Calm Complex?

    KSM-66® Ashwagandha is the highest concentration, most bioavailable full-spectrum root extract on the market. We keep the same ratio of effective nutrients as the ground root in a more concentrated form and derived only from the roots of the plant. This is 100% safe and with no toxicity risk.
