If you've researched ashwagandha recently, you've met the scary version of this story. Someone on TikTok or Reddit describes taking it daily for months and ending up flat: music stopped hitting, hugs stopped feeling warm, "nothing is fun anymore". The word that gets used is anhedonia, the clinical term for losing the ability to feel pleasure.
We sell ashwagandha. It would be convenient for us to wave this away. We're not going to, because the honest answer is more useful, and frankly more reassuring, than either the panic or the denial.
Where the "emotionless" claim comes from
Ashwagandha's whole job is turning things down. It's been studied mostly for stress and anxiety, and the better trials, several using the KSM-66 root extract at 600mg daily, found meaningful reductions in stress scores and in cortisol, the hormone your body releases under pressure. In one frequently cited 2019 trial, people taking 600mg of ashwagandha daily for eight weeks reported significantly lower anxiety than the placebo group.
Now look at that mechanism from a different angle. If a supplement dampens your stress response, a dialled-down feeling is not a malfunction. It's the product working. For someone who arrived anxious and wired, that registers as calm. For someone who took it casually, or took too much, or took it for a year without a break, that same dampening can register as flatness. Same dial, different starting points.
That's the charitable reading of the online reports, and we think it fits most of them. A few honest caveats before anyone relaxes completely, though.
What the evidence does and doesn't show
Published clinical trials, typically running 8 to 12 weeks, haven't reported anhedonia as a side effect. Reported side effects in trials are mostly mild: digestive upset, drowsiness in some people. One widely shared response on Reddit's ashwagandha forum puts it bluntly: nowhere in the scientific literature has ashwagandha been reported to cause an inability to feel pleasure. Only on Reddit.
But the absence of trial evidence isn't complete evidence of absence, and here's why we won't fully dismiss the reports. The trials ran for two or three months. Many of the flatness stories describe six months or a year of daily, uninterrupted use, sometimes at doses well above the studied 600mg. Almost nobody has formally studied that pattern. When lots of separate people describe the same experience from the same usage pattern, the grown-up response is to take the pattern seriously, not to call them all liars.
There are also case reports, rare but real, of liver problems associated with some ashwagandha products, more often linked to poorly standardised extracts of uncertain origin. Worth knowing, and another argument for buying a verified extract rather than mystery powder.
So our position: at the studied dose, for the studied duration, in people without contraindications, ashwagandha looks safe and the emotionless claim doesn't hold up. Used carelessly, forever, at random doses? Nobody can promise you anything, including us.
How to use it so this never becomes your problem
Three rules cover almost everything.
First, use the studied dose of a standardised extract. KSM-66 is a branded root-only extract that's been used in a large share of the modern clinical research, standardised to at least 5% withanolides, the compounds doing the work. Our Organic Ashwagandha KSM-66 provides 1000mg of it per serving with organic black pepper, and it's certified organic by the Soil Association. Whatever brand you buy, "root extract", "standardised" and a named withanolide percentage are the words to look for. Proprietary blends that won't tell you the dose are a no.
Second, don't take it forever without breaks. The long-uninterrupted-use pattern is where the worrying anecdotes cluster, and plenty of experienced users cycle it: eight to twelve weeks on, then a couple of weeks off. Cycling also gives you a clean read on what it's actually doing for you, which after months of daily use you genuinely can't tell anymore.
Third, notice why you're taking it. Ashwagandha suits a stressed, wired, sleep-poorly person. If you're not stressed and you're taking it because a fitness influencer said it boosts testosterone, you're taking a stress-dampener you don't need, and "I feel a bit flat" is a fairly predictable review for you to end up writing.
Who shouldn't take it at all
This part is short but non-negotiable. Skip ashwagandha, or talk to your GP first, if you're pregnant or breastfeeding, have a thyroid condition (it can nudge thyroid hormones), take medication for anxiety, depression, blood pressure, blood sugar or immunosuppression (interactions are possible), have liver problems, or have a nightshade allergy. If you're on an SSRI, this is a conversation with your doctor, not with the internet.
What taking it well actually feels like
Worth setting expectations, since ashwagandha suffers from both overselling and over-fearing. It isn't a sedative and it isn't a happy pill. People who respond well describe the edge coming off: the 2am mental to-do list quietens, the disproportionate irritation at small things shrinks, sleep comes easier. In the trials this builds over weeks, not hours, with stress measures separating from placebo around weeks 4 to 8. One of our favourite descriptions from a long-term user: "it didn't add anything, it subtracted the static".
That subtraction is the whole product. If it ever starts subtracting things you wanted to keep, the answer is simple and undramatic: stop taking it. Reported flatness resolves after stopping in most accounts, over days to weeks.
The bottom line
The emotionless claim is the internet's exaggerated version of something true: ashwagandha dampens your stress response, which is precisely why it works and precisely why it deserves respect rather than casual, indefinite use. Studied dose, standardised extract, breaks every couple of months, and a clear reason for taking it. Do that and the evidence, on balance, is on your side.
And if you've read all this and decided ashwagandha isn't for you, that's a fine outcome too. We'd rather you skip it than take it badly. Magnesium in the evening is the gentler place many people start, and we've written about that combination here.
Quick answers
Does ashwagandha cause anhedonia? Clinical trials haven't reported it. Online reports cluster around long uninterrupted use at high doses. Studied dose plus regular breaks is the sensible protection.
How much ashwagandha should I take? Most positive trials used around 600mg of a standardised root extract daily. Our KSM-66 serving provides 1000mg of extract standardised to 5% withanolides.
Should I take it in the morning or at night? Either works; the effect builds over weeks rather than per-dose. Drowsy types take it in the evening.
How long until it works? Trials show stress measures improving over 4 to 8 weeks. Give it a month before judging.
What happens when I stop? No known withdrawal. Effects fade over days to weeks, which is also why cycling off is a useful self-test.
Food supplements should not replace a varied, balanced diet. Ashwagandha is not suitable during pregnancy. If you take medication or have a health condition, check with your GP first.
