Curated, not stocked.
Reishi earned its place on our shelves because the evidence base is more substantive than most adaptogenic supplements, and DIRTEA's single-ingredient approach respects that. There is nothing hidden in the formula — just the mushroom. We suggest it to patients looking for a measured, low-risk addition to a stress or sleep protocol, particularly where blood work has flagged immune or cortisol concerns worth monitoring.
About this product
Reishi
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.

Common questions
Frequently asked
What does Reishi actually do in the body?
Reishi 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.
When is the best time of day to take this?
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.
How long before I notice a difference?
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.
Is it safe to take alongside other supplements or medications?
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.
How does a powder format compare to capsules?
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.
