Definitely what I needed. I don’t take it every day but it comes in clutch when I find myself feeling overly stressed or after a big training block. Will be ordering more for sure.

SOUND FAMILIAR? 🤔
Stress doesn’t always feel like stress. A lot of the time it just looks like this:
- Laying in bed at night with your mind racing, unable to switch off?
- Keep hitting that snooze button and refusing to drag yourself out of bed in the morning?
- No matter how hard you try you just can't lock in?
- Can't focus, thoughts clouded by brain fog?
- Your workouts seem harder than they should be - weak, low energy, fatiguing fast?
If more than a couple of those ring a bell, it probably isn’t that you need to try harder. It could be that you're sitting in a constant state of stress.
WHAT DO YOU WANT BACK?
KSM-66® Ashwagandha is supported by 90 randomised, double-blind, placebo-controlled studies. Pick what matters to you and see what the trials found.
Take the edge off
Across multiple high-quality human trials, KSM-66 has been shown to significantly reduce stress and anxiety scores, and serum cortisol (the stress hormone). Participants also reported significant increases in happiness and perceived quality of life, and lower levels of stress-related food cravings.

reduction in stress symptomsGHQ-28 questionnaire
Fall asleep faster, wake up sharper
KSM-66 significantly improved sleep quality — a reduction in sleep latency (the time it takes to fall asleep), improvements in total sleep time, and improved alertness and feeling of restfulness on waking.
69%
improvement in overall sleep qualityIxoreal studies
Stronger, bigger, better recovered
KSM-66 significantly improved muscle strength, muscle size and recovery across both men and women. Significant improvements in cardiorespiratory endurance were also observed, with VO2 max (oxygen capacity) significantly improved for both men and women.
Support for healthy hormone levels
KSM-66 has been shown to support healthy hormone levels in both men and women. Men saw significant increases in total and free testosterone and dihydrotestosterone (DHT). Women saw favourable improvements across estrogen, progesterone, prolactin and more, and menopausal women saw reductions in symptoms including hot flashes and perceived stress.
Improvements for both men and women
For men, studies show significant improvements in overall sexual function, arousal, orgasm and sexual drive, alongside increased semen volume and sperm count and quality. For women, studies show significant improvements in overall female sexual function scores — arousal, desire, lubrication, orgasm frequency and quality — and reduced sexual distress scores.

MOST ASHWAGANDHA IS A GAMBLE
Ashwagandha quality can vary massively, that's why we only use KSM-66® Ashwagandha!

Every batch, independently tested
Ashwagandha is a plant, and plants vary. So each batch is assayed for actives and screened for contaminants before it is capsuled. These are the results for the batch this tub came from.

QUESTIONS?
How long before I notice anything?
Give it eight weeks. Most of the research on KSM-66 runs for 8 to 12 weeks, and that is where the meaningful results show up.
Sleep is usually the first thing people mention, often inside the first couple of weeks. As an adaptogen, it takes some time to build and you won't necessarily feel something immediately, so if you are waiting for one you will decide it does not work long before it has had a chance to.
When should I take it?
One capsule a day. For general use, mid-morning. If you are taking it mainly for sleep, take it 30 to 60 minutes before bed.
Taking it at some point each day beats a perfect time you keep forgetting.
Will it make me drowsy?
It should not. It is not a sedative and it does not knock you out — most people describe feeling less wound up rather than sleepy.
Some people do feel noticeably relaxed. If that is you, move it to the evening and use it as a wind-down instead.
What if I don't feel anything?
That is a fair question and it deserves an honest answer.
Ashwagandha usually shows up as an absence rather than a presence. The small stuff bothering you as much, getting to sleep without the nightly mental replay, a shorter recovery from a bad day. It is the kind of change you notice looking back a month, not the kind you feel an hour after a capsule.
Take it daily for eight weeks before you judge it. And if it genuinely is not for you, it is not for you - that happens, and we would rather you know that than keep buying it out of habit.
Do I need to cycle it or take breaks?
There is no established need to. The clinical work runs 8 to 12 weeks continuously, and some studies have gone longer.
Plenty of people prefer to take a week or two off every few months anyway. Nothing wrong with that.
Can I take it with coffee, or with my other supplements?
Coffee is fine, they are not working against each other, and ashwagandha will not blunt your caffeine.
It stacks fine with the rest of our range too. If you are on prescription medication, always consult with your GP to be safe
Is it vegetarian?
Yes. The capsule is HPMC, which is plant-derived.
Older label artwork says gelatin, but every batch from August 2026 onward uses HPMC vegetable capsules, and the artwork is catching up.
Why root only, and does it matter?
It matters. Ashwagandha leaf is much higher in Withaferin A, the compound behind most of the caution around the plant, and leaf material is cheaper to include.
KSM-66 is extracted from the root alone, with no alcohol or chemical solvents. Our batch tested at 0.03% Withaferin A against a specification of 0.1% or less. Most products will not tell you either number, because most do not measure them.
I've read that it makes you feel numb or emotionless. Is that real?
People do report it, and we are not going to wave it away.
You will not find much about it in the clinical trials, partly because of what those trials measure. They track stress scores and cortisol, not whether you still enjoy things. The people describing this online are describing something the research mostly did not think to ask about.
The likely explanation is straightforward. What ashwagandha does is take the top off your stress response, some people who were used to massive lows and massive highs because of poorly managed stress may view stability and calm for "numb", when in reality... they're just actually chill for once!
Some things worth remembering - if you take an antidepressant, emotional blunting is a well-documented effect of those on their own, which makes it very hard to tell what is causing what, talk to your doctor before adding this.
I've read that ashwagandha can hurt your liver. Is that true?
There are case reports, and we are not going to pretend otherwise. Around 23 have been published, usually appearing between two and twelve weeks after starting, and usually resolving once the person stopped taking it. Against how many people take ashwagandha worldwide, it is rare - but rare is not never.
What the reports have in common is worth knowing. A lot of them involve multi-herb blends, or products that turned out to be mislabelled or to contain something other than what was on the front. That makes it genuinely hard to say what caused what.
It is a large part of why we sell a single identified extract, from one plant part, tested batch by batch, with the certificate published on this page. It is not a guarantee (nobody can give you one) but it removes the question of what is actually in the capsule.
Stop taking it and see a doctor if you get unusual tiredness, nausea, itching, dark urine, or any yellowing of the skin or eyes. If you have a liver condition or you drink heavily, talk to your doctor before you start.
Who should not take this?
Do not take it if you are pregnant or trying to become pregnant, or if you are breastfeeding.
Always talk to your GP or prescribing doctor if you're on prescription medication and are unsure.

Have been using KSM-66 everyday now since launch and I’ve noticed some massive improvement to my everyday life stress the way my body operates and tackles situations, Paired with CALM and my sleep has improved 110% I value my sleep being a natty gym goer so it’s really important for me that it helps me achieve some deeeep sleep!
3rd bottle in and essential part of my night routine. Actually felt a huge difference in my quality of sleep when they had the audacity to sell out and I couldn’t get my hands on it for a bit. That was rude.
As a frequent night shift worker this ksm66 stacked with Calm has increased my sleep quality tenfold. Love it
Great product. Helping me sleep after shift work at all hours.
Thus stuff is next level. Literally from the first night I took it, it has given me a more restful sleep and I am able to wake up at 5am to workout feeling ready to go! It's actually amazing stuff and my smartwatch has picked up on this too, giving me way better sleep scores and higher body battery scores as well which is super telling! Will definitely keep purchasing!
Amazing stuff. Just glad there’s an NZ company that can be trusted for this stuff which is traditional underdosed and shit. Leaving country so won’t reorder but I love it and I hope you guys are the biggest NZ brand when I come back
Really enjoying this! Helping with my sleep heaps when combined with calm. Will buy again!
A friend put me onto KSM after she got seriously sick of listening to me complain constantly about the lack of sleep (and quality sleep) I was getting. It has definitely helped with getting-to-sleep, as well as waking up less exhausted. I am also far less likely to make questionable life decisions, or snap at my most useless colleagues purely from lack of sleep. 10/10 from me.
First time using Ksm-66, very happy with the results, especially the sleep quality. Paired with Uglyface Calm, my sleep has never been better.
The KSM/Calm 1-2 punch has been game changing for my sleep. Now sleeping unbroken much more regularly and getting deeper, more restorative sleep as a result. Genuinely a life changing product
Been getting some good sleeps and haven’t been so stressed like I normally do
Love this stuff! Can feel the effects after just one day, and it helps me get to sleep quickly when I take it in the evening, not to mention the other effects… ;)
The KSM-66 is a game changer, my morning brain fog is reduced and my sleep quality has been drastically better.
Apart from absolutely pumpin in the bedroom, way better sleeps and not groggy asf in the mornings anymore
I have never slept so well than with this combined with Calm
Great product
Great combo and love the transparency with the ingredients
Definitely feel more relaxed after taking it! Finding it a lot easier to fall asleep which is awesome.
I like that theres no chalky taste like other brands I've tried. Good deal too
I have been taking this in conjunction with the Calm for a week now, and I have noticed an improvement in my sleep quality. I could go to sleep ok, but going back to sleep after getting up to the toilet was hit and miss, and I now feel like that has improved somewhat. Looking forward to more good sleeps to help with muscle recovery too.
Regret not using KSM sooner.
I take one tablet each evening along with two calm tablets. I get a great night's sleep and feel less stressed during the day. Will buy again.
Great paired with calm to help me get to sleep faster and deeper. Love it
Didn't have high hopes for this product, but it sure does deliver! I take 30-60 minutes prior to my night routine and go pretty much straight to sleep, and sleep way deeper as well. No more thinking round in circles, my brains feels totally calm and switched off, in a good way.
This really worked for me I've tried a couple products and they didn't deliver the results I wanted
Actually feel the effects better than the standard pharmacy stuff.
I was a bit skeptical about this at first, but after taking it for a while i was convinced it was a good product.
Really good stuff
I’ve noticed a positive effect of this supplement. And will be ordering more in the future.
Very good quality
Great product- does exactly what you would expect it too!
Have only been taking it with calm at night, so not sure if I have noticed the benefits yet. Awesome fast delivery.
A++++
Must have in my life now
Has helped me in all the ways described, already ordered my next lot
A+ product will keep buying
Works a treat
A+
