DIRTEA Reishi is a single-ingredient mushroom powder made from 100% Reishi (Ganoderma lucidum), one of the most studied adaptogenic fungi.
DIRTEA Reishi is a single-ingredient mushroom powder made from 100% Reishi (Ganoderma lucidum), one of the most studied adaptogenic fungi. As an adaptogen, it is thought to help the body maintain balance under physiological and psychological stress, rather than acting as a stimulant or sedative.
Mix one teaspoon with water, coffee, or another warm drink. It can be taken in the morning or evening - many people prefer it at night given Reishi's association with relaxation and sleep support. Follow any additional guidance on the packaging.
DIRTEA Reishi is a single-ingredient mushroom powder made from 100% Reishi (Ganoderma lucidum), one of the most studied adaptogenic fungi. Reishi has a long history of use in East Asian medicine and is now studied in modern research for its potential to support stress regulation, immune modulation, and sleep quality. As an adaptogen, it is thought to help the body maintain balance under physiological and psychological stress, rather than acting as a stimulant or sedative.
This is a practical choice for people who find themselves running on cortisol - those with demanding schedules, disrupted sleep, or a sense that recovery is lagging. It fits naturally into an evening wind-down routine or as a daily baseline supplement for immune resilience. Because it contains no caffeine, it can be taken at any time of day without affecting sleep architecture.
DIRTEA focuses on functional mushroom products, and their Reishi powder uses a single-ingredient format, which avoids the noise of multi-ingredient blends and makes it straightforward to assess whether the product is working for you. For anyone who has confirmed elevated stress markers or immune vulnerability through testing, a Reishi powder like this offers a clean, food-based way to begin addressing those findings alongside broader lifestyle changes.

Your Profile
Your first order creates it. Add your blood results or a wearable, and a doctor can recommend what suits you.
Sign inReishi contains bioactive compounds — primarily triterpenes and beta-glucans — that are studied for their effects on immune signalling and stress response. It is classed as an adaptogen, meaning it is thought to help the body regulate, rather than override, its stress systems. It does not sedate or stimulate.
Either morning or evening works, but many people take Reishi in the evening given its association with relaxation and sleep support. It contains no caffeine, so it will not interfere with sleep if taken later in the day.
Adaptogens are not fast-acting in the way that, say, caffeine is. Most research and clinical experience suggests a consistent daily intake over four to eight weeks gives the clearest indication of benefit. Track how you feel — sleep quality and stress tolerance are useful markers.
Reishi may have mild immune-modulating and anticoagulant properties, so if you are on immunosuppressants or blood-thinning medication, speak to your GP or pharmacist before starting. For most healthy adults it is well tolerated at typical daily amounts.
Powder allows you to adjust your intake more easily and integrates well into drinks or food. The trade-off is slightly less dosing precision than a capsule. Check the packaging for the recommended serving size and stick to it while you assess how the product suits you.
Overall

Started adding this to warm oat milk about six weeks ago before bed. Hard to say exactly what shifted first but I'm waking up feeling less wired — like my baseline anxiety has dropped a notch. I'd been sceptical of mushroom supplements generally but the single-ingredient format sold me on trying it properly. Will be repurchasing.

Bought this after a particularly brutal few months at work. Takes a couple of weeks to notice anything, but the edge comes off. Not sedating at all, just a bit calmer under pressure.

The powder itself is great — I've been sleeping more soundly since week three and feel less run-down during cold season. My only complaint is the packaging: the zip-lock seal on the bag is pretty flimsy and I've had it pop open in my supplement drawer twice now. Would love a proper resealable pouch or a tub option. Four stars for now, five when they sort that out.

Swapped from a multi-mushroom blend to this and it's much easier to tell what's actually doing something. Been using it for two months now and my sleep tracker is showing longer deep sleep windows. Good product.

I take this every evening stirred into chamomile tea. It doesn't taste of much — faintly earthy but nothing off-putting. I'd been dealing with disrupted sleep for months after a stressful period at work and this has genuinely helped me wind down without reaching for anything heavier. I appreciate that there's nothing else added to it, makes it easy to stack with other things.

No complaints about the actual product — I've noticed steadier energy and I seem to fight off colds faster than I used to. But at £38 for what is essentially a month's supply if you're generous with portions, it does feel a bit steep. I'll keep buying it but I do find myself measuring the scoop more carefully than I should. Would drop to a smaller size at a lower price point in a heartbeat.
