Reishi mushroom has been used in traditional Chinese medicine for centuries to improve overall health and well-being. Nicknamed the “mushroom of immortality”, it’s now one of the most researched adaptogens for sleep, stress and immune support.
Do reishi mushrooms help with sleep?
Yes — despite not being a sedative, several studies support reishi’s effects on sleep. One study found that reishi extracts taken for three days significantly increased total sleep time and non-rapid eye movement (NREM) sleep. As an adaptogen, reishi also helps the body adapt to stress — one of the most common causes of poor sleep.

Benefits of reishi mushroom for sleep
Reduces fatigue and low mood
Fatigue and low mood are closely linked to poor sleep. A study in 132 people with neurasthenia found that eight weeks of reishi supplementation reduced fatigue and improved overall wellbeing.
Promotes relaxation
Reishi contains compounds with a calming effect on the nervous system, helping the body enter a natural sleep cycle rather than relying on sedatives.
Boosts the immune system
Research in cancer patients showed certain molecules in reishi increase natural killer cell activity. A healthier immune system generally supports better sleep quality.
Anti-inflammatory properties
Chronic inflammation is linked to sleep disorders. Reishi contains biologically active compounds that are anti-inflammatory and may improve sleep quality.

Reduces anxiety
Reishi works on the HPA axis, helping regulate the stress response and reduce cortisol. This calming of the mind is one of the key reasons it supports sleep.

How to take reishi for sleep
Reishi can be added to soups, stews or smoothies, used in aromatherapy, or taken as a supplement. The two most practical options for sleep support are:
Reishi mushroom tea or cacao
A warm reishi drink before bed is one of the most enjoyable ways to incorporate it. Our Reishi Mushroom Adaptogenic Complex blends reishi into a rich cacao powder — ideal as an evening wind-down ritual.

Reishi supplements (capsules, powders, tinctures)
Powders are versatile and can be mixed into hot drinks, smoothies or protein shakes. Capsules are a convenient daily option. Tinctures offer the fastest absorption.
When to take reishi for sleep
Most traditionalists recommend taking reishi in the early evening around dinner time, giving the compounds time to work before bed. The benefits accumulate over time rather than appearing immediately after one dose, so consistency matters more than precise timing.
- Take reishi consistently — daily use is key to building the sleep-supporting effects
- Take with food — reishi is better absorbed alongside a small meal or snack
- Follow recommended dosage — more isn’t better and may cause unwanted effects
Reishi mushroom dosage for sleep
Most experts recommend 1–3 grams per day for general use. For sleep specifically, some suggest up to 5 grams. Always start low and build gradually while monitoring how your body responds. Follow the dosage on your product’s packaging.
How to choose a quality reishi supplement
- Standardised extracts — look for stated beta-glucan or triterpene content
- Third-party tested — check for purity and potency certificates
- Right format — choose powder, capsule or tincture based on your routine
- Read reviews — look for real customer experiences over marketing claims
- Consult your GP — especially if you take medication or have existing health conditions
Frequently asked questions
