  • Excellent quality and noticeable effect
Size: 60 Count (Pack of 1)
I have been taking these Ashwagandha KSM-66 capsules from Nutricost for several weeks and have noticed an improvement in my energy level and my ability to handle daily stress. The capsules are easy to swallow, they have no unpleasant taste and the 600 mg presentation seems adequate to me

  • Ashwagandha extract will it normalize my Cortisol level
Size: 60 Count (Pack of 1)
This is Ashwagandha extract. I am taking it to see if it affects my Cortisol levels resulting in hormone balance. It's a good product and not too expensive like some similar products

  • Best Ashwagandha supplement I've found!
Size: 60 Count (Pack of 1)
I've been buying my family's Ashwagandha supplement from a different online store. But when I went to reorder, the other store was out of stock, so I came to Amazon to find a comparable supplement. Now I'm so glad that the first store ran out. This brand's supplement is stronger and therefore we only need to take one capsule vs two every morning. And even though this is stronger, it is less expensive! That's a huge win! I feel like this is a great quality as I have extra energy and stamina during my days. I've been ordering this now for six months and have never had any problems. Yes, I highly recommend this Ashwagandha supplement. ... show more

  • Not Much More Than an Expensive Placebo Effect
Size: 60 Count (Pack of 1)
As someone who's experimented with a bunch of different herbal supplements, I had high hopes when I decided to give Nutricost's KSM-66 Ashwagandha extract a try. The promised stress relief, enhanced focus, and improved mood sounded incredibly appealing. Unfortunately, after diligently taking these capsules daily for a couple of months, I can't really say I noticed any substantial effects - positive or negative. No discernible reduction in my anxiety levels, no boost in cognitive powers, no extra reserves of calm under pressure. Just kind of...the same old me. Now, I'll caveat that by saying everyone's body chemistry is different, so supplements can definitely produce varying results from person to person. Maybe these just didn't work harmoniously with my own systems and biochemistry. But from my personal experience? This particular Ashwagandha product didn't really "do" much at all. The capsules themselves seemed fine as far as quality and potency claims. No weird after-tastes or side effects. But also no real tangible benefits to point to, at least not for me. I kept waiting for that renowned ancient herbal magic to kick in and have me feeling like a freshly rejuvenated monk. But after sixty pills, I simply felt...pretty much the same as before I started taking them, just a decent chunk of change lighter in the wallet. So unless you're already a true believer in Ashwagandha's effects and just want a reputable brand, you may want to temper your expectations before pulling the trigger on these. Or at least be prepared that they could potentially just be a very expensive placebo for you. For me, they were about as impactful as taking multivitamin gummies - which is to say, not terribly impactful at all. Not a terrible product necessarily, but also not quite the natural wonder tonic I was envisioning either. ... show more
