It's simple. We got tired of ashwagandha labels that shout big numbers and hide the details.
Ingredients
Each 2-capsule serving contains 1000mg of KSM-66® full-spectrum ashwagandha root extract (Withania somnifera), standardized to ≥5% withanolides — the bioactive compounds behind ashwagandha's studied benefits. Root only, never the leaf, extracted with a 14-year-refined solvent-free process.
Other ingredients — all three of them: HPMC capsule shell (plant-based), microcrystalline cellulose, silicon dioxide.
Allergies
Vegan and free from gluten, dairy, and nuts. No synthetic sweeteners, no artificial colors, no gelatin. Made in a GMP-certified facility.

Clinically Studied
KSM-66® is the most extensively studied ashwagandha root extract available, evaluated in more than 70 randomized, double-blind, placebo-controlled human trials examining support for a healthy stress response, sleep quality, mood, and cognitive performance.† We chose it deliberately: it is the extract the research was actually done on — not a look-alike.
Third-Party Testing
Every batch — not a yearly sample, every batch — is tested by Eurofins (ISO/IEC 17025 accredited) for identity, potency, heavy metals, and microbial contaminants. The Certificate of Analysis is published on this page and included in the box — no email request required.
Each bottle holds 60 capsules — a full 30-day supply. Take 2 capsules daily with a meal and a full glass of water. Consistency beats intensity with adaptogens: clinical studies run 4–8 weeks of daily use, so pick a time you won't forget and let it stack.
Therapeia Zoi KSM-66® Ashwagandha supports a healthy response to everyday stress, promotes relaxation and restful sleep, and helps maintain calm focus and balanced energy through the day — all from one precisely dosed serving.† It's calm that doesn't flatten you and rest that doesn't leave you groggy.
Our hope is that two small capsules a day can quietly retire the shelf of half-used stress remedies you've collected — and give you your evenings back.

“I grew up around herbs. That’s probably why I’m so particular about what earns a place in my cabinet.”
“For me, ‘natural’ isn’t enough. I want to know which extract is being used, how much I’m actually getting, and whether someone bothered to test the finished product. I liked seeing KSM-66® Ashwagandha clearly identified and the testing made available instead of hidden behind marketing language. Simple, considered, and easy to understand.”

I bought this product to try as it was new in the store and quickly identified that it is definitely manufactured with premium quality ingredients. One of the few products in this category which came with lab certification results which came me confidence that proper testing was done. Easy to use - I’m definitely going to try their travel friendly options.One note to Amazon: When I search the product, it sometimes takes me to another product Therapearl - might need to correct it.
This supplement seems well formulated and responsibly produced. The flavor is natural and not overpowering. I appreciate that the dosage is clearly stated. It took about a week before I noticed benefits, but once I did, the results were consistent. Overall, a high quality supplement.
Get to review this finally, have to say after the first week I was skeptical but after the second week man I’m so glad I found this. Definitely a far better sleep, much more calm, and locked in. I had an interview and used this to get some extra half to rest and feel more balanced and this answered that for me. 5/5 for me, and must try.
On my third bottle now
She told me to try ashwagandha to offset the effects of my ridiculous coffee habit. I was doubtful. But 7 weeks in I have to admit she was right. The cortisol spikes I used to feel all afternoon have calmed down. Sleep is so much better. I cut from 5 cups to 2 without even planning to.
What sets this apart is the COA from Eurofins they put inside. Most brands just slap 'lab tested' on the bottle but this actually shows u the document. Smart move. And yes it does seem to help with daily stress.
Including a lab test with microbiological and heavy metals test results in the box is how you build real customer trust. Not clever marketing. Actual proof of safety and quality. I've told three friends about this already.
Energy feels more stable throughout the day
I think people quit too early with ashwagandha. I nearly did. Was drinking 5 coffees a day, anxious and not sleeping. Took 5-6 weeks before I felt real change. But the change was proper - not a fake buzz like caffiene. Actual calm. Better sleep. Less dependency on coffee. This works if you stick with it.
Spent years in a caffiene-anxiety loop and never connected the dots. A friend who works in wellness suggested ashwagandha to help lower cortisol. It took about 5-6 weeks to feel real results. But when it kicked in I slept better than I had in years and the need for 4-5 coffees just faded on its own. Should have tried sooner.
A must have in my cabinet
KSM-66 makes the difference
This is my first time trying ashwagandha and I’ve had a really good experience so far. I mainly wanted something to help with stress and feel more balanced day to day.After taking it consistently, I’ve noticed I feel calmer and less reactive to small things. It’s not dramatic — just a steady, subtle difference. I also like taking it in the evening because it helps me wind down without feeling drowsy.The capsules are easy to take and I like that the ingredients are simple and clean. Overall, I’m really happy with it and would buy it again.
Used to joke I was fuelled by coffee and running on empty. 5 cups a day and still tired. The ashwagandha gradually got my body out of that constant high alert mode. It took about 6 weeks but now I sleep through the night most days and I dont need more than 2 cups to feel functional. Big change.
Less reactive, more patient
KSM 66 is one of the more well known forms of ashwagandha, so that’s a good start. If you’re taking it for stress support and general mood balance, this is the type most people look for.Capsules are easy to take, no weird herbal burps afterward, which I appreciate. It is one of those supplements you do not “feel” instantly like caffeine. It’s more of a slow burn. After a couple of weeks, I just notice I am less reactive and sleep feels a bit deeper.Vegan, clean label, nothing complicated. Just straightforward adaptogen support.If stress is your uninvited roommate, this is a reasonable way to turn down the volume a notch without feeling sedated.
Verified by independent lab
I added this KSM-66 ashwagandha supplement to help manage everyday stress, and it’s been a great choice. Within a couple of weeks, I noticed I felt more balanced and relaxed, especially in the evenings. It’s gentle on my stomach, easy to take, and I appreciate that it’s vegan and non-GMO. If you’re looking for natural support for mood, relaxation, and better sleep, this one is definitely worth trying.
Okay, I have been taking this for about two weeks.I felt no difference for a week, but I didn't expect I would. It takes some time to build up levels.I am starting to notice very subtle changes, which is what you want. This isn't something you take in crisis to immediately calm you. This is what you take to slowly create a more subtle overall wellness.I have had no digestive issues or negative side effects.
Plant based capsule, love it
I work in finance and stress is constant. I was also pouring coffee into myself all day. Sleep was non existent basically. These capsules dont fix stress but they seem to help your body handle it better. The anxiety from caffiene is much less now. I sleep 6-7 hours which is a lot for me. Worth trying.
Added to cart on a friend's recommendation a while back. Telling everyone now. This is the best supplement I've used for stress.
I've been using ashwagandha on and off for a while now — picked up different brands from Costco, Amazon, wherever really. They were okay but I never felt super confident about what I was actually getting. When I came across these KSM-66 capsules I decided to give them a try.First thing — the packaging immediately stood out. It feels premium and well made, not like the generic bottles I'm used to. But what really got me was when I opened it and found an actual lab test report inside the package. I've never had a supplement brand do that before. And then I noticed the same lab results are on their Amazon listing too. That right there increased my trust big time.Now I'll be honest — ashwagandha isn't one of those things where you feel it overnight. From my understanding the real benefits take a couple of weeks to kick in. But that's the nature of it.The fact that they use clinically-backed KSM-66 and are this transparent about their testing — that's what separates them. I've been through enough random brands to know the difference when a company actually cares about quality.Definitely sticking with these.
Began taking these for anxiety a few weeks ago. The improvement is steady and real. Can't imagine stopping.
Anxiety had been affecting my daily life badly. Started these with low expectations. By about week 5 things had shifted considerably. So much better. On my 4th bottle now.
Outstanding supplement
Added to cart for nerves and they've helped alot. Life changer for daily anxiety and stress.
Picked these up for nerves and they have genuinely changed things. Highly recommend without hesitation.
Mold and yeast tested - clean bill
Picked these up for nerves and they helped more than expected. Highly recommend to anyone dealing with anxiety.
Was using 5 coffees to survive a high stress job. Jittery, anxious, barely sleeping. Started ashwagandha and committed to 8 weeks minimum. Nothing for the first 3 weeks. Then gradually the anxiety softened. By week 7 I was sleeping 7 hours and needing 2 coffees instead of 5. The patience was worth it.
