KSM-66 Ashwagandha Extract Capsules

Ashwagandha, which is scientifically known as Withania somnifera, is a plant that belongs to the nightshade family. It appears as a short perennial herb with bright, orange-red fruit and green, bell-shaped flowers.

The herb, particularly its roots, is one of the foundational components in Ayurvedic use and has been used for centuries as a natural dietary supplement, much like ginseng. In traditional use, ashwagandha was used to support vitality and virility. It was also used as an alternative for muscle aches.

While ashwagandha appears in various formulations and extracts, KSM-66 is unique as the highest concentration full-spectrum extract. Full spectrum refers to an extract that contains a balance of components from the original herb instead of over-representing any single component.

How KSM-66 Ashwagandha Extract Capsules Work

The exact mechanisms of action have yet to be determined, though it is understood that ashwagandha is an adaptogen.

Much of the herb’s effects come from a blend of its active constituents, which mainly comprise alkaloids like somniferine, tropine, and withanine, along with steroidal lactones known as withanolides. More than 140 withanolides have been identified and isolated in ashwagandha.

KSM-66 Ashwagandha Benefits and Uses

KSM-66 ashwagandha extract benefits are wide ranging. As an adaptogen, ashwagandha creates a sense of relaxation, increasing its potential use as a supplement to support healthy stress levels. This may also be beneficial to those in need of a mood boost. Ashwagandha may produce calming effects. Even to those with relatively healthy minds, ashwagandha has shown a generally soothing effect.

As a nootropic, ashwagandha has been shown to promote mental focus. Early studies also suggest that the herb can help to support memory formation and may potentially be used as an alternative to support healthy brain function.

Ashwagandha may promote healthy cellular function. Studies suggest that its soothing properties promote energy and support healthy stress levels.

Ashwagandha has also shown high potential for improving physical health. Research shows that the Ashwagandha herb may promote joint and muscle health.

Why Buy KSM-66 Ashwagandha?

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.

    10/10 Recommended

    I take this twice daily and it took about a week to notice the effects, but it’s fantastic. Normally stressful situations are much more manageable. I also overall just feel better. Great product.

  • Kristina Asmus - 24th Jun 2020


    Great stuff

  • Kimmie - 10th May 2020


    Excellent product. Helps my energy level and moods. Very balancing for my body and mind.

  • Stephen - 25th Feb 2020

    Helps significantly with a wide variety of things

    This stuff is magical. I don't fully understand how it works, but it helps me in almost all areas of life. I've been taking it for about a month now, and I've been sleeping better, I have much less overall anxiousness (I'm a VERY anxious person), my general confidence is a bit higher, and my sex drive has been absolutely crazy. The most noticeable effect has surprisingly been on my sex drive. Not only the drive itself, but my confidence in the bedroom has also skyrocketed. I usually struggle a lot with anxious feelings about performance during sex, but since I've been taking this, I feel extremely sexy to the point where I'm almost as attracted to myself as I am to my partner. It's been fantastic.

    Couldn't recommend this product enough.

  • Justin - 27th Jan 2020

    Stress and strength

    Noticed I’m a lot more easy going and not as neurotic at work. Even joking around. Also increased my deadlift personal record.

  • CDD - 17th Jan 2020


    Best Quality I have found.

  • Eddie Kwong - 5th Jan 2020


    I have been taking nootropics since around 2017. It's taken many years to figure out what works and want doesn't.

    I've tried other formulations of Ashwag off and on for the past several years. I never saw any meaningful effect. But when I read about this KSM-66, I thought I'd give it a try again.

    Today is day 2, and I'm feeling hyper-focused and ramped up. Working on Sunday is usually not like that. So that is a good sign. I'll update this review as I go along.

    This product has helped my mood and all round well being.

  • HUGO - 21st Aug 2019

    KSM-66 ROCKS

    Been using 3 caps per day. One on wake and one mid day and one night. Main thing to note is stress level is very low and recovery from hard gym workouts is greatly improved. This KSM-66 is then best I have taken and Nootropics Depot is reliable and ordering and shipping very good and fast.

  • Nolan Johnson - 26th Jul 2019

    Highest Quality Ashwaganda

    Makes sleeping easy and I even look forward to going to bed more nowadays. Love the wake up.

  • Trevor Wiebe - 23rd Jun 2019

    Use as instructed

Results were weird my brain was awake body was exhausted. couldn sleep at all that night. Mental burn out the next day. And the next day, feeling grumpy aggitated.

  • Camilla Kristine Karlsen - 4th Jun 2019


    This ashwaganda is great! I have already placed a new order.

  • LHB - 2nd Jun 2019

    The Best Ashwagandha I've Tried

    I gave up on Ashwagandha some time ago after trying three highly reviewed brands including two purportedly made from KSM 66 extract. All of them made me feel mildly lousy. This is a whole different story. Feels very pure and puts me in a very relaxed mildly energized state that lasts a very long time. I only need one capsule in the afternoon to carry me until bedtime. Makes for as really nice afternoon mini stack when paired with Mucuna which unfortunately ND does not carry (HINT). Recommended without reservation.

  • Julie Ritchie - 12th May 2019

    Good choice for alleviating stress

    I have tried a few different brands of ashwagandha and this one ranks up there. I only gave 4 stars because it didnt seem better than the last brand I tried but every bit as good as. This one is a solid choice. Effective at helping keep stress down.

  • LF - 19th Apr 2019


    I started taking this three weeks ago to help with my elevated cortisol which was causing an inability to lose weight and lack of sleep. Sleep is slowly improving (I just added Sensoril from Nootropics Depot at night), weight has gone down a smidge but I also stopped snacking in the afternoon, and the biggest surprise is that I feel genuinely happier. I don’t know if it’s 100% from this product but I do know that I haven’t felt this level of happiness and contentment in a very long time. I know Ashwagandha helps with anxiousness and mood but I wasn’t really experiencing either of those so this new feeling of happiness was a surprise. Has anyone else experienced this?

  • Gino - 11th Apr 2019

    ksm 66

    I've been taking this product for about 5 weeks already and I noticed that my anxious feelings and panic attacks are almost not there at all, one more thing that I noticed is that my sex drive is super high and I haven't felt like this since I was 18 and I'm 40 years old right now!

  • Jonas Krikstopaitis - 20th Mar 2019

    Really good product

    Great product and service

  • Unknown - 27th Dec 2018

    Stress relief and weight loss support

    Ever since starting this Ashwagandha my mood has improved - I sleep better and I'm finally able to lose weight! It does work! I've tried other brands like Gaia Herbs but never got the results I wanted.
