What is KSM-66 Ashwagandha Powder?

Ashwagandha, also known as Withania somnifera, has been a widely used and studied Ayurvedic herb for centuries, mainly for its potential effectiveness in supporting healthy stress levels.

How is KSM-66 Ashwagandha Powder Made?

There are many Ashwagandha powder options on the market, but none quite compares to KSM-66. Committed to quality and safety, Ixoreal Biomed invested over 14 years of research and development in the creation of KSM-66. Made strictly from the roots (no leaves) of the plant for maximum clinical effectiveness, KSM-66 is acquired through a unique extraction process based on “Green Chemistry” principles, which do not make use of alcohol or synthetic solvents.

KSM-66 Ashwagandha Benefits

KSM-66 Ashwagandha benefits the body and mind in multiple ways, as shown through clinical trials and research studies. In fact, KSM-66 is the most extensively studied Ashwagandha extract on the market.

The bioactive constituents (compounds) of the Ashwagandha herb that are widely studied and lend to its positive effect on humans include notable alkaloids and over 35 withanolides. This is why KSM-66 is recommended for stress management. This relaxing effect may also be helpful for sleep.

Besides supporting stress management, studies have shown KSM-66 to be a helpful aid in the following areas:

  • Cognition and memory* - One study showed improvement in executive function and attention, two key areas of the Wechsler Memory Scale.
  • Energy and stamina* - One study showed that Ashwagandha led to improvement in cardiorespiratory endurance and self-assessment scores for healthy athletes.
  • Weight management and well-being* - Increased levels of cortisol can signal your body to hold on to excess fat. Reducing cortisol levels not only helps stress but also weight loss and general feelings of well-being, according to one study.
  • Muscle strength, size, and recovery* - Ashwagandha has been shown to help healthy, active adults improve max resistance load and muscle recovery.
  • Testosterone levels in men* - One study found the herb to improve semen volume, sperm concentration and motility, serum luteinizing hormone (LH), and testosterone levels.
  • Libido in women* - One study reported improvements in desire, arousal, and satisfaction for women using Ashwagandha.

Why Buy KSM-66 Ashwagandha Powder?

Apart from the benefits we’ve discussed, there are several reasons to buy KSM-66 Ashwagandha.

  1. High-concentration, full-spectrum extract: 14 years of research and development paid off. Only Ixoreal has managed to refine an extraction process that maintains the natural balance of the constituents in the herb. Through “Green Chemistry” processing, Ixoreal’s science team found a way to holistically process Ashwagandha to preserve efficacy of active constituents in their natural proportions, including withanine, somniferine, tropine, steroidal lactones, and withanolides.
  2. A safer root-only extract; not made from leaves: Traditional Ayurvedic texts as well as the standard pharmacopoeias of India, Britain, and the U.S. describe solely the root for use. Many other manufacturers include extracts of the leaves, but there is no data supporting the efficacy or safety of such practices. KSM-66 is the highest percentage available in root-only Ashwagandha extract at 5% concentration, and the amount of withaferin A found in this extract is negligible and, most importantly, very safe.
  3. Most extensive studies and research: Ixoreal leads the industry in performing clinical trials and research to investigate effectiveness of Ashwagandha in humans, collaborating with major research and academic institutions. All Ixoreal studies are randomized, double-blind, and placebo-controlled.
  4. Efficient pricing for highest-quality product on the market: Ixoreal uses cost-efficient business practices to pass savings on to customers, as it’s the only Ashwagandha manufacturer on the globe that manages its own farms, production facilities, laboratories and research center.
  5. Certifications you can trust: KSM-66 has attained more than a dozen trusted certifications for product quality and business practices. KSM-66 is 100% USDA Organic, Non-GMO Project verified, Certified Gluten-Free, JK Kosher, and more, as well as being GRAS-affirmed by the FDA. In line with WHO-cGMP and US-FDA, KSM-66 is manufactured in an ISO 9001:2008- and GMP-certified, state-of-the-art cleanroom facility. Additionally, KSM-66 is vegetarian and shelf-stable.
  6. Superior taste: Ixoreal’s unique extraction process preserves the compounds and lends itself to a neutral taste in foods and beverages. Other manufacturing processes, including hydroalcoholic, lead to a bitter taste.
  7. Award-winning product: KSM-66 has earned multiple awards.
        • “Herbal Industry Leader 2016” by Society for Ethnopharmacology
        • “Product Innovation in Botanicals 2014” by Frost and Sullivan
        • “Best Botanical Ingredient 2013” at Engredea/Natural Products Expo West
        • “Innovative Ingredient of the Year 2012” at Panacea

Always discuss the addition of nootropics and supplements with your doctor or another trusted healthcare professional, and stay informed about how a product might affect your unique body chemistry--everyone is different.

    i felt less stress and more calm

    I will try again

  • Aaron W - 14th Jun 2020

    Pretty Good for Rest Stack

    Some get more out of Ashwaghanda and with most adaptogens it takes time to build up in the system or nourish the nervous system notably. I like it more then straight root tea but its really subtle. Goes well if I want to balance my caffeine jitters and my sleep rest stack, nothing to write home about.

    Great Balls of Fire

    This product is 100% a staple and I usually cycle for 6-8 weeks along with Muria Pumia for quite an effective stack all things hormones and sexual function!

    Less drowsy than other formulations

    I got this in the ashwagandha sample pack. I read in one of the ND articles that the KSM-66 should be more stimulating than the other varieties of ashwagandha, so I was hopeful that it actually would be because I hate feeling sedated and tired (I hate sleeping).

    I took 300mg and was pleased that it did make me feel calm, but also slightly focused. The focus effects didn't last as long as the calming effects, but the calming effects weren't so intense that I felt tired. Just...calmer. I have pretty bad anxiousness so the mild combination of stimulation and calm was nice. It was subtle, but nice. I will experiment with this stuff more, maybe in combination with caffeine next time.

    Ashwagandha KSM-66

    Satisfied with the quality. I take 300 mg 2 times a day after meals. Increases mood and well-being. Ashwagandha is safe plant with proven effectiveness. It improves the quality of sleep, increases testosterone and libido, improves cognitive function. I recommend.

  • Cliff Michaelson - 20th Oct 2019


    I like this variety. I take it during the day & it helps anxiousness and irritability. Like to always have it.

  • Jonathan - 24th May 2019

    Too messy

    The “effects” are too brief or not there. Also it’s powdery consistency lent it to being everywhere else but in my body.

  • Mercedes - 1st May 2019


    I took 300mg a day until it was gone. Consumed during a rough patch in my marriage + full time school + keeping the toddler alive. The effects were very subtle. I did feel myself adapting to the stress of life quicker. I also felt less motivated to do school or house work, but I think that stemmed from a huge regulation of stress.

    Good quality product. Fast shipping. I will buy again when life calls for it.

  • Sean - 1st May 2019

    I Love KSM66

    Another "licensed" type of of ingredient. I love KSM66. I only use 1/8 tsp and enjoy microdosing ingredients now. Great for reducing stress, cortisol and increasing testosterone naturally. Has a nice mood enhancing effect

  • Andrew - 29th Apr 2019

    Game changer

    I love this stuff. I have tried Ashwagandha in the past, but it was snake oil compared to this! This stuff makes me feel calm and energized throughout the day. In my opinion this combined with L-Theanine works better than anything I’ve tried in the past. 5 star would highly recommend

  • Kyle Cassell - 23rd Apr 2019

    Amazing for stress.

    Amazing for stress

  • Star - 15th Nov 2018

    High Quality

    This is a good ASHWAGANDHA product and recommended.
    Sublingual use of the powder is preferred delivery.

  • al - 29th Aug 2018

    not for me

    I have used 300mg in the mornings for a couple weeks, and have not noticed anything besides a runny nose. If I take it at night, my mind races and I cant get to sleep, so I know it works.

  • David - 17th Jun 2018

    Levels you out

    Not an overly dramatic feeling, but I can feel this every time I take it. This will be a mainstay in my supplement regimen.

  • erika gephart - 6th Jun 2018

    works good

    Good product as described quick shipping

  • Brett - 21st May 2018

    Excellent - although stimulating

    Not sure if I'm the only one whose experience this, but I found it to be rather stimulating (in a good way). I found it better to take KSM-66 in the morning.

    Sensoril ashwagandha appears to be better before bed.

    Effects were very noticeable; pretty much destroyed most of my stress. I think I've even made some gains out of it (test boosting effects).

    Not claiming ashwagandha to be a "miracle herb" but it sure is beneficial :)

  • citrus skeptic - 23rd Apr 2018

    Nothing wrong with it

    Great for regulating the thyroid

    Reduces stress levels

    Read about its slew of effects here:

    Might excessively increase thyroid activity causing insomnia. I think it's giving me insomnia, even though hypothyroidism runs in my family.

    Unsure whether tolerance/dependence forms to its GABA effect. I guess you could take it with Emoxypine if you're worried. Emoxypine normalizes GABA.

  • Olaus - 13th Apr 2018

    Pure Ashwangada Powder

    A quarter teaspoon in my smoothie every morning as a tonic for mental Health, libido and agility. Works Wonders! Effect comes gradually and is noticeable after 3-4 weeks. Recommended. Helps against stress and irritability + Works as a muscle toner as well.

  • J.V. - 24th Mar 2018

    an amazing product

    I didn't feel fatigued at all throughout the day, energy was sustained and also help me sleep better. Consumed Twix a day once in morning and at around 2:00. I would recommend this product. Also helped with libido.

  • Unknown - 20th Mar 2018
