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.
  • “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.

    Great Product Great Service

    It does exactly what it advertises and blows the competition out of the water. I was disappointed when I had bought another variation (non-KSM 66) in a supplement store. I decided to try ND and I was completely satisfied. I will be a lifelong customer.

    Great stuff

    I take two at night to take the edge off at the end of the day. I told my sister to give this a try. I take it at night and wake up totally refreshed. Gives me a nice clear relaxed state of being and mind. Can't say enough good things.

    Great product

    I asked my psychiatrist about this herb and he said it was good.
    I take it every night, and I sleep well.

  • ian - 13th Jan 2018

    racing thoughts

    This stuff definitely does something but doesn’t agree with my brain chemistry well. Gave me speedy thoughts. Don’t use at night. Will try the other more relaxing version if I ever buy again.

    First of all, Nootropics Depot’s response time for an order is fast. Every order that I’ve placed has been fulfilled within 24 hours and shipped out. I generally receive their products within 2-3 days after shipment. Their products are genuine. This is the first time I’ve tried Ashwagandha in capsule form. It seems to take the edge off, help me focus, and complete work in a timely manner. Thank you!

    Great Stuff

    I have been recommending this product to friends and family. It has really helped me and I've gotten a lot of feedback from others. It doesn't make me feel tired or out of it, just mildly relaxed

  • Unknown - 18th Sep 2017

    Way to strong, bad side effects

    No doubt this stuff works.
    I taken it twice now and the second time I took it, I felt so wasted the next day it was unbelievable. I seriously feel like I died and that I am watching my own self.

    I know this product works good for some people, I think it depends on your thyroid also.

    But for me I wish I never taken this stupid thing, it's been 36 hours and I can't even move and seems like I got blurry vision, I am not taking anything else so I know that this stuff caused it.

    Nootropics Depot on the other hand is 5 PLUS Stars and ROCKS. No complaints there! :)

  • John - 10th Aug 2017


    Okay, its been a few weeks of use now. Immediately after taking one pill in the afternoon, I felt very chilled out almost too chill. I wouldn't want to drive lets just say. So now I only take it at night an hour before bed and I still feel residual effects but in the best way. I get great sleep and wake up before my alarm which is the weirdest thing for me. But I love this stuff.

    Slight boost in energy.

    After using KSM-66 daily for about a month, I've began to discern it's effects from not taking it on brief occasion. It gives a palpable increase in motivation and clarity. Nothing to put your psychiatrist out of business but may give some extra footing amidst a mental rut.

  • Unknown - 7th Jan 2017

    Good product, but with one complaint.

    I have enjoyed taking this Ashwagandha. It has improved my memory, as well as my cognitive and creative abilities. What I like about it, is also what I dislike about it. It really accents my emotions. When I am happy, I am really happy, but when I am angry or frustrated, I become rude, and almost intolerable to be around. So bad so that I notice how poorly I am behaving whilst I am behaving that way! Has anyone else had this issue? Otherwise, a good product!

  • Kyle - 3rd Dec 2016


    This is the best ashwaganda i've ever tried. Nootropics depot continues to impress me again and again. Thank you for your integrity and prompt professional service.

  • Unknown - 27th Oct 2016

    Extremely Potent

    This product and the other product I purchased from Nootropics Depot (L-Theanine) are extremely potent. I had my doubts about trying Ashwagandha again after using it in the past with not effects, but am admittedly more than satisfied with the results of this product. you don't care about anything negative in your life after taking this product for two weeks. The only negative aspect of using this product would be the sleepiness I experience when using the product and that is the only reason I must discontinue using the product.

  • Unknown - 20th Oct 2016

    Best ashwagandha

    This is the stuff you are looking for. Perfect for keeping you calm during the day, but not making you tired or drowsy. I take one of these in the morning, and I can actually stand my coworkers!

  • Rick - 17th Sep 2016

    Helps with mood !

    works even better in a stack but stand alone useful also.

  • Michael - 3rd Sep 2016

    Excellent Product

    i was using another asshwagandha product but find the KSM-66 far superior. It clearly has helped me reduce my cortisol levels as I can see a decrease in my midsection. I highly recommend this product and thank Nootropics Depot for a quality product and fast shipping.

  • Chris R. - 24th Aug 2016

    Very good, high quality Ashwaganda in ND's KSM-66 Capsules, personally need 2x for effect

    This is my first month of taking Nootropic Depot's KSM-66. I am really pleased with the calming effects in seems to exert, as well as the fact that after swallowing, there is no aftertaste as I have experienced with other Ashwaganda supplements. The capsules are smaller than the big "00" size caps, which makes them easy to swallow. Personally, I find them more useful in the late afternoon and early evening. I do take more than the recommended dosage, but have offset by skipping on some days. Perhaps I need to remain consistent with taking same, rec. amount daily? All around: Def worth a try and I would not attempt to seek anywhere outside of Nootropics Depot.

  • srubek - 15th Aug 2016

    Score +1 for Nootropics Depot (as if they needed it)

    Thanks, MYASD/ND/Ceretropic/Paul/team, for carrying this. I think it's helping a good friend with some issues, and he's only in his first week. This is much better than westerns approach.

    I think this is far superior to any ashwagandha extract (and may be the ultimate one, in the end).

    +1 for NootropicsDepot, +1 for Ayurveda, +1 for extraction/synthesis//patented consistency.

    Thank you Paul and team. You're not only helping me; you're helping my friends, too.

  • josh - 3rd Jul 2016

    great addition to any stack

    Since I started taking KSM-66 it feels like recovery after exercise has been exceptionally improved. Cortisol is a huge factor and suppressing it even a little is a good thing.

  • Kellz - 3rd Jul 2016

    love the stuff

    I'm a cyclist and I use this stuff to help with a little extra natural form of recovery and performance increase. I also find this stuff helps me relax, and I find I sleep really well when taking this.

  • Kyle W - 22nd Jun 2016

    Works well

    This is one I keep coming back to. The dosage seems spot on
