"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."

Does what it’s supposed to do. Was concerned about rising cortisol and lack of sleep. This Ashwagandha works well. I feel more relaxed and sleep well!

I've never had ashwaganda pure enough to have a serious effect...this stuff has a serious effect. The reduction in stress is profound, but it occurs without any kind of depressant effect. It's very strange. You just...don't feel stressed. Things that seemed like serious problems seem solvable.I am baffled that this stuff isn't more popular.It also had a dramatic increase on my total testosterone values as tested by blood tests before and after the supplement. Definitely recommend...and it's cheap!
