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 medicine 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. Adaptogens refer to natural compounds designed to help you adapt to stress and maintain homeostasis.

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. Ashwagandha achieves this by reducing the immunosuppressive effects caused by stress and the concentrations of cortisol (the main stress hormone, in your body). This may also be beneficial to those in need of a mood boost. Ashwagandha my produce calming effects, many of which are similar to GABA (gamma aminobutyric acid). 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 has also been shown to possess powerful antioxidant properties and neuroprotective abilities. Antioxidants neutralize free radicals, compounds created during the process of cellular oxidation. Free radicals can damage cells in your brain and body, leading to age-related decline. Antioxidants prevent this damage, potentially resulting in greater longevity.

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. Extracts that include the leaves can gain a higher percentage of overall withanolides, but this comes at the cost of increasing the amount of withaferin A, an undesirable cytotoxic withanolide. 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.

    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.

    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.

    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?

    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

    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.

    Instant Cortisol Control

    Good for cortisol & testosterone

  • Unknown - 1st Sep 2018

    Great Product

    Shipping is fast and product is awesome! I use it to help me sleep at night and it definitely does the trick, without the morning grogginess that happens with things like melatonin.

  • Alex - 2nd Aug 2018

    Great stuff.

    Works better than nutrawchamps organic ashwagandha. this is the best ashwagandha I've ever tried.

  • Unknown - 30th Apr 2018

    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.

  • vanessa steckler - 22nd Mar 2018

    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.

  • Annie - 4th Feb 2018

    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.
