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. 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.
  3. 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, 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.
  4. 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.

    Did some research and I bought these for their therapeutic effects of anti-anxiety and also helping with social anxiety situations and being able to sleep better at night. Have not taken it long enough at all to notice any effects but looking forward to it!

  • SSS - 22nd Aug 2021


    Was skeptical, I am now not. I am back to purchase everything I can find to do with anxiousness. I've been suffering for 25 years, and after some reviews for ashwaghanda on youtube, I came here. I trust ND, and their products, and their reviews. I tried the product for several weeks, and noticed a difference within a few days, my anxiousness reduced. I did go on to have panic attacks when I ramped up the pressure at work, hence I'm looking to increase my arsenal of nootropics and adaptogens to complement KSM-66. Embarrassingly I've also sought out hypnotherapy to address the underlying root causes, and I've had some success. Right now my cart is sitting at $500 and I'm not sure whether to pull the trigger, or wait for my appointment with my naturopath to workout the best regime...if I was smart I'd wait...But who trusts medical professionals these days anyway? Dr. Google knows best.

  • Juan velazquez - 7th Aug 2021

    Not working for me

    I have then taking it for 2 weeks now and I have not felt any effects just wondering if I can take two a day can someone can give advice on this ND Admin: You can take two a day. Some people need higher doses. Sometimes people just don't respond to ashwagandha, too. Lemon balm might be a better alternative.

  • Cam - 22nd May 2021

    Pretty Good Stuff

    I felt the effects within about a day and a half. It effectively reduced anxiousness to basically nothing as long as I took a pill a day. The trade-off was it sapped a bit of my motivation and caused lethargy, the latter of which wasn't necessarily a bad thing. In situations where I need to make important decisions, I can decide without worry and actually focus on what needs to be done rather than the stress of the situation. I'm currently taking one per workday and taking breaks on weekends.

  • Jason - 21st May 2021


    Very pleased with my purchase. Sleeping much better and waking with more energy. I also feel like my testosterone is higher. Muscle tone is actually becoming toned! Great stuff!

  • Dustin DeBolt - 13th May 2021

    Best Ashwagandha

    This is the best source of ashwagandha on the market. Great for the calming effects and long lasting anti anxiety properties.

  • Riely - 22nd Apr 2021

    It works

    It works on many different levels, after a week of use my energy levels sky rocketed compared without it. Maybe low T. Levels? Not sure but it's been a life saver and my workouts have been on point as well with increased muscle mass which I'm thinking it's because of increased testosterone

  • Joslyn - 22nd Mar 2021

    Blown away

    I got this for stress and to hopefully help out my semi slow thyroid a bit. Within 1 week of taking it the intolerance to cold stopped and my stress has calmed down quite a bit. I take 1 capsule a day with dinner. Definitely sleeping better. And dreaming! Kinda oddball dreams but hey I am not complaining. Its amazing stuff. Helps out nicely for issues caused by hormone imbalances too. But the body temps I have struggled with my whole life. So for me this supplement has been both life changing and improving. And I absolutely love it for that.

  • Dustin - 2nd Mar 2021

    Calming Benefits

    Ashwagandha is one of the classic calming herbal therapeutics. This product is great when taken with any other supplement that can cause anxiousness or jitters. Look up for yourself the other long list of benefits for this ancient compound, you wont be disappointed. Taken for around 5 months with no adverse side effects.

  • Zeee T - 18th Feb 2021

    Life Changing

    Wow! Amazing product. I have been taking KSM-66 Ashwagandha from another source and ND brand is hands down, the best you could find out there. I was elated with how this product works. I have various issues that negatively impacts me neurologically. Day one I took it, I couldn’t believe the focus, brain function and my brain fog is non existent. Also helped keep me calm during the stressful part of the day. I have been taking it for 2 weeks now and I can say, this is a supplement will stay in my health and wellness supplementation.

  • claire thomas - 6th Feb 2021


    it's good i think should be taken with food

  • Melissa Gravell - 20th Jan 2021


    Subtle but calming

  • Patrick Miller - 13th Jan 2021

    This stuff is seriously good

    The name of it made me kinda skeptical. It just sounds herbally and I had no clue how effective it would be. But MAN does this stuff make you resistant to stress/anxiousness. I will admit the first two times it gave me headaches late in the day, but as others have mentioned, it stops happening with regular use.

  • TIMOTHY JAMES BRENNAN - 7th Nov 2020

    KMS 66 Ashwagandha is a Solid Plant that helps me with Energy and Strength. Overall a more focused and productive me!

    This is a good supplement.

  • Wesley Williams - 7th Nov 2020

    Great products!!

    This product is extremely great. It was delivered in an extremely timely manner. Much better quality than other supplements I’ve tried.

  • Daniel - 23rd Oct 2020

    Focus and Recovery

    This works great, I feel my strength go up in the gym, I feel more relaxed and I tend to sleep much better. Awesome supplement that everyone should try at least once.

  • Jackson Dean Chase - 21st Oct 2020

    The non-drowsy ashwagandha you've been looking for

    I'm pleased with the KSM-66 formulation; it is definitely more stimulating (or at least not sleep-inducing) than other forms of ashwagandha. I have no problem taking it first thing in the morning. Not sure it does much for cognition, though it doesn't hurt. Some people say KSM-66 can make certain users more aggressive; I have not found that to be true—at least not in my case. I would definitely buy KSM-66 again, although right after I got my first bottle, Nootropics Depot launched the new Shoden variety. That looks intriguing and is the version I'll try next. KSM-66 will remain a reliable fallback if the Shoden doesn't work as well. As always with nootropics and everything else in life, your mileage may vary. You may do better on a different ashwagandha (such as Sensoril) or no ashwagandha at all. Nootropics Depot offers an ashwagandha sampler if you're looking to sample your options before you commit to a full bottle.

  • Mike Stanley - 26th Aug 2020

    It's good

    Has lots of uses. Definitely took too much for better effects that ended up backfiring making me feel sluggish but initially it was very cathartic experience for me. Recommend to anyone that doesn't have thyroid issues

  • DJ Blose - 1st Aug 2020

    No difference

    I had high hopes but I haven’t seen a difference since taking this supplement.
