"This is by far the best Reishi on the market. More potent, more therapeutic dosage — I can literally feel my nervous system relax after taking it."
— Carly W., Verified Buyer ★★★★★
You want to sleep deeply. You want your immune system working properly. You want your nervous system to stop running hot.
Reishi (Ganoderma lucidum) is the most-researched medicinal mushroom on earth — over 1,000 published studies, nearly 300 meta-analyses, and a clinical use history spanning more than 2,000 years. Its polysaccharide extract, GLPS, has been studied and used clinically in China since 1973.
Our Reishi is a certified organic 10:1 dual extract from 100% fruiting bodies — with a confirmed beta-glucan content of 31.7% (our specification is ≥30%, independently verified by third-party COA). That's the concentration that makes the research meaningful. Not a sprinkle. The real thing.

What the Research Shows
Fatigue and Wellbeing — RCT (n=132)
A randomised, double-blind, placebo-controlled trial of 132 adults found that 1,800mg of Reishi daily over 4 weeks produced statistically significant improvements in fatigue, anxiety, and general wellbeing compared to placebo. The researchers concluded Reishi had a "beneficial effect on the quality of life" (PMID: 15857210).
RCT, 2005. 132 participants, 4 weeks.
Immune Function — Cochrane Systematic Review
A Cochrane systematic review of Reishi found consistent evidence of immune-modulating activity, with reviewed trials reporting improved immune response and quality-of-life measures in supplement users. The reviewers described Reishi's capacity to "stimulate host immune defences" as a notable finding across the trials analysed (PMID: 22696372).
Cochrane SR, 2012. Multiple trials reviewed.
Cholesterol and Lipid Markers — RCT (n=110)
A randomised double-blind crossover RCT of 110 participants with dyslipidaemia found that Reishi spore oil produced significant reductions in triglyceride levels compared to placebo (PMID: 40077714).
RCT, 2025. 110 participants, crossover design.
Broad Evidence — Critical Review (2015–2020)
A critical review of Reishi literature confirmed clinical evidence for immune modulation, antioxidant activity, liver support, and metabolic benefits. Reishi's polysaccharide (GLPS) has been studied and used clinically in China since 1973. Toxicological data supports a good safety profile at standard supplemental doses (PMID: 34411377).

What Customers Say
"I swear by a reishi before bed, I always feel so calm and soothed and drift straight off to sleep. It has been absolutely life changing for me."
— Paige Z., Verified Buyer ★★★★★
"After my husband's passing I was having restless nights. My daughter suggested Teelixir. Now I take it each night before bed and it helps me sleep."
— IVY B., Verified Buyer ★★★★★
"Excellent product! Works great to calm and relax my body. I get through the day with more energy and less fatigue."
— Urszula K., Verified Buyer ★★★★★
"This Reishi is my favourite! I just mix it with hot water and drink it. I have tried a few different ones and they don't compare to the quality of Teelixir."
— Kadri S., Verified Buyer ★★★★★
Why Concentration Matters
Reishi has a hard woody texture when fresh. You can't just grind it and sprinkle it in your coffee. The bioactive compounds — beta-glucan polysaccharides and triterpenes (ganoderic acids) — are locked inside a cell wall structure that the human body cannot break down efficiently without extraction.
That's why extraction method and ratio matters more for Reishi than almost any other mushroom. Our dual-extraction uses hot water to release the water-soluble polysaccharides, and ethanol to capture the fat-soluble triterpenes that hot water alone cannot reach. The result: a 10:1 concentrate with a confirmed 31.7% beta-glucan content — measured against our ≥30% specification and verified by independent COA testing.
By comparison, whole dried Reishi powder contains 1–5% beta-glucans in bioavailable form. You would need 6–30 grams of whole powder to match the active content in 1 gram of our extract. That's a meaningful difference.

Research-supported use (RCT evidence)
You want an adaptogen that calms rather than stimulates

You want a quick energy boost or stimulation
Not this — try Cordyceps instead
You dislike bitter flavour entirely

How to Use It
Daily serve: 1–2 grams (approximately ½–1 teaspoon). Most customers use Reishi in the evening — it's calming rather than stimulating, and the RCT showing fatigue improvements used a daily regime consistently over weeks.
Best in:
Hot water (traditional) — simply dissolve in hot water for a traditional preparation. "I just mix it with hot water and drink it" (Kadri, verified buyer)
Evening cacao or hot chocolate — Reishi's earthy, slightly bitter note complements raw cacao naturally
Herbal tea — dissolve in a chamomile or ashwagandha tea for a compounding calming effect
Coffee — if you prefer morning use, it adds an earthy depth. Less common than evening use but works well
Golden milk — combine with turmeric, black pepper, coconut milk, and honey
Taste note: Reishi has a characteristic bitter-earthy flavour. The bitterness comes from the triterpenes — the same compounds associated with the liver and immune activity. Start at ½ teaspoon and adjust. Adding honey or coconut milk rounds it out.
Pairs Well With
Lion's Mane — the most popular stack: cognitive clarity (Lion's Mane) + deep calm (Reishi). Multiple customers reported using both daily
Ashwagandha — for stress-driven sleep problems, combining adaptogens addresses both cortisol and the nervous system
Cordyceps — for those wanting performance alongside immune and recovery support
Yes. The bitterness comes from triterpenes — particularly ganoderic acids — which are the fat-soluble compounds unique to Reishi. These are captured specifically by the ethanol extraction step. If a Reishi product has no bitterness at all, that's a red flag: the triterpenes are likely absent. Our 31.7% beta-glucan COA and dual extraction confirm both compound families are present. Start with ½ teaspoon and adjust. Honey or coconut milk softens the flavour substantially.
When should I take it — morning or night?
+
Evening is the most common pattern and tends to produce the most noticeable effect for sleep quality. Most of our customers mix it into a warm evening drink — cacao, herbal tea, or just hot water — about 30–60 minutes before bed. You can take it in the morning too, particularly if stacking with Lion's Mane or Cordyceps — there's no contraindication. Experiment with what feels best for you.
How long before I notice anything?
+
The RCT showing fatigue and wellbeing improvements ran 4 weeks at 1,800mg daily. Some customers — particularly those using it for sleep — notice effects within a few days. Others find it takes 2–4 weeks. Reishi is not a sedative — it doesn't knock you out. It works by calming the nervous system and supporting the body's natural sleep mechanisms. The effect is gentler and more gradual than most people expect.
What's the difference between your Reishi and a cheaper powder?
+
Most cheap Reishi is either (a) ground whole mushroom — which cannot be meaningfully absorbed without extraction, (b) mycelium grown on grain — which is mostly grain starch, or (c) extracted but not COA-verified for beta-glucan %. Ours is a 10:1 dual extract with a published, independent COA showing 31.7% beta-glucans. You are not guessing at potency — it's confirmed. The Cochrane review, the RCT, and 1,000+ studies were conducted on extracted polysaccharide preparations, not raw whole mushroom powder.
Is Reishi safe to take long-term?
+
Reishi has a 2,000-year history of traditional use and the available toxicological data supports a good safety profile at standard supplemental doses (1–3g extract per day). GLPS has been used clinically in China for over 50 years, with extensive safety tracking over that time. Rare reports of digestive discomfort exist at high doses. If you take blood-thinning medication, consult a healthcare practitioner — Reishi has some platelet activity. Pregnant or breastfeeding individuals should consult a practitioner before use.

Customer Reviews
Overall rating: 4.9 / 5 from 225 reviews.
I am finding with the Reiche Mushroom powder I am sleeping better and waking up feeling refreshed.
I have been taking Teelixir's Reishi Mushrooms for a few years now, having developed an autoimmune condition and being highly recommended to try it by other sufferers. I fairly quickly was able to stop taking any medications and my immune system has been completely rebalanced. My blood results are excellent and even the specialists are somewhat confounded. Not only that, I feel healthy and less stressed, I sleep much better and have not had one episode of colds, flu or infection. Yeehah!!
I am almost 70 years old - I have been taking Reishi Mushroom since 2019 - I haven't had a cold or flu since then - no flu injections and I take no medication. I feel really really well. I eat as clean as possible and exercise regularly and sleep like a baby!!

Hi Mathew, thank you for your feedback. We are happy to hear that you are experiencing such tremendous results with our Reishi Mushroom.
Always keep reishi in stock. My favorite to have on evening to wind down before sleep. Also this is one of the best for beta glucan content!
Perfect for after dinner before sleep. Would recommend it for anyone who is looking for something relaxing.
Flavour is not to strong, will definitely be buying it again.

Hi Suzanne, you are most welcome. happy to hear you are enjoying your Reishi Mushroom. Thank you for your feedback.
This Reishi is my favourite! I just mix it with hot water and drink it. I don’t have any issues with the bitter taste. Better to keep it pure and simple. I have tried a few different ones and they don’t even compare with Teelixir’s Reishi. I take it in the evening to chill out and sometimes in the morning because it helps me keep calm and carry on. Long term benefits come slowly but steadily so I decided purchase a half a kilo bag. Happy to get discount when buying in bulk. Also got a nice whisk as a present which was a pleasant surprise! Thank you! Appreciate the quality!

Hi Jo, we're so incredibly pleased that you're experiencing such terrific results with Reishi Mushroom! We really appreciate your positive feedback.
I have been having Reishi mushroom in my morning coffee since Feb 2019 -I am well rested each morning when I wake up - I feel great pretty much most of the time and even though I work with the public on a daily basis I have not have had any kind of flu or virus at all

Hi Erica, happy to hear you are enjoying your Reishi Mushroom. Thank you for your feedback.
This mushroom is awesome, my sleep cycle's have never been better, I'm way more relaxed and calm in a stressful position. Love this mushroom have it every day in my coffee.
Store owner replied:
Hi Cassandra, happy to hear you are enjoying your Reishi Mushroom. Thank you for your feedback.
Ive tried a lot of different Reishi powders and this is by far the best!! Resihi is very difficult to store as it takes on moisture so easily, other companies often store their powders in foil bags with ziplock tops, and they are so hard to use and keep moisture out of! These tins with the included freshness sachet are THE BEST! Flavour is great, and I really find drinking Reishi once per day helps with my immune system and inflammation.
Store owner replied:
Hi Jordan, happy to hear you are enjoying your Reishi Mushroom. Thank you for your feedback.
I have been taking Teelixir's wonderful Reishi mushrooms (& other products, including ashwagandha, fulvic minerals and siberian ginseng) for the past three years. My autoimmune condition has been put into remission and my health has improved dramatically. I am hugely grateful for this immune and stress relieving help, especially in these challenging times. I am also really grateful for Teelixir's amazingly prompt, helpful and always loving customer support when needed. Thank you.
Store owner replied:
Hi Sophia, happy to hear you are enjoying your Reishi Mushroom. Thank you for your feedback.
I make up a smoothy, with a teaspoon of this product, along with a couple of other items every morning, first thing! I have really noticed an improvement in my fitness and well being. FYI, I am 75 years old and can do heaps, which the girls at work (half my age or quarter) CANNOT do!!! I can REALLY recommend it to you.
