What is reishi mushroom, and what does it do?
Reishi is a fungus, also called Ganoderma lucidum and lingzhi, that grows in various hot and humid locations in Asia. It's rich in beta-glucans and triterpenes, compounds valued for their role in immune health, and it carries a 2,000-year history in East Asian herbal medicine.
Traditionally, people have taken it to support the immune system, reduce stress, improve sleep and lessen fatigue. There is some scientific evidence of its effectiveness, including lab research and some small human studies. More research is still needed to fully understand what reishi does for inflammation and immune function.
Reishi is known as the mushroom of immortality in traditional practice, and the reputation fits its character. It doesn't hype you up. It keeps you steady.
Where does reishi fit in a day that already feels loud?
Reishi sits on the calm side of your day. It supports healthy sleep patterns and relaxation without sedation, supports the body's natural response to everyday stress, supports immune system function and supports emotional wellness.
Unlike stimulants or quick-acting supplements, reishi is commonly used for long-term wellness, particularly by people who want better sleep quality, stress adaptation and immune balance. Traditionally it's used to help the body adapt to everyday stress and support overall resilience, with immune support and a sense of calm balance.
Regulation is resilience. When your nervous system stops running at full volume, everything else gets easier: the inbox, the meeting, the 4pm decision you keep putting off. Think of reishi as your calm dial, turned up just enough that you can think straight, not so far that you're sleepy. Centred, not sedated.
How much reishi is in a daily serve of Hoola, and in what form?
Every 10 g scoop delivers 400 mg per gram of Ganoderma lucidum (Reishi) fruiting body extract, dry equivalent, which is 4,000 mg dry equivalent per serve. Every per-serve figure below is the per-gram figure times ten. Both are published.
For context, reishi mushroom has most often been used by adults in doses of 1400 to 5400 mg by mouth daily, usually in divided doses, and reishi extracts have also been used in lower doses. Optimal doses have not been set for any condition, which makes a standard dose very hard to set. Capsule products can sit far lower again, with some containing 500 mg of reishi each.
Hoola is a Listed Medicine on the Australian Register of Therapeutic Goods, AUST L 508472, ARTG start date 8 August 2025, sponsor Hoola Australia Pty Ltd. The certificate lists all 27 active ingredients with exact quantities per gram. Anyone can look up AUST L 508472 on the public register and check every number. No proprietary blends. We provide full formula transparency, including dosages of all functional ingredients, nothing to hide.
Why did Hoola choose a fruiting body extract?
We chose a fruiting body extract because the part of the mushroom you use changes what you get. Products differ widely in extraction methods, sourcing, and whether they use fruiting bodies or mycelium, and all of that affects potency and effectiveness. Quality and active ingredients in supplements can vary widely too.
The market shows the spread. Some reishi products are freeze-dried whole mushroom sold with myceliated substrate. Some use high-pressure dual extraction of the fruiting body grown on Duanwood to reach a 20:1 extract. An extract isolates one or two compounds from a plant or mushroom, suspending them in water or alcohol to make a liquid. Those are very different things in the same aisle.
Sourcing matters for a second reason. Mushrooms are highly absorbent, which is why experienced foragers avoid picking near roadsides where pollution is taken up, and mushrooms can also take up heavy metals from contaminated water sources.
So we set the bar at the manufacturing end. Hoola is manufactured in Australia by BJP Laboratories Pty Ltd, Yatala QLD, with Australian laboratory testing. We use active and bioavailable forms wherever possible, in line with Australian quality manufacturing standards, and we formulate at meaningful and puposeful dosages. We didn't want another stimulant. We didn't want another sedative. We wanted bright, steady, clear and capable. Chill without the crash.
How does reishi work with the rest of the formula?
Reishi is the recovery side of the blend, so the energising ingredients have a stable foundation to work on. It's a traditional adaptogenic mushroom used to support immune function and overall vitality. Test-tube studies have shown that reishi can affect the genes in white blood cells, which are critical parts of your immune system, though some details are still uncertain.
Around it, the rest of the squad does its own job. Ashwagandha leads the Calm Clarity side. Bacopa handles memory, recall and retention. Cordyceps is the Energised Performance counterpart, included for sustained, lower-key energy support through the day, where caffeine offers a short, sharp lift. Korean ginseng brings stamina and drive. Caffeine sits at a measured dose so it can do its job on alertness and focus without dominating the rest of the formula, with 100 mg roughly equivalent to one standard cup of brewed coffee.
Hoola is designed as a single, balanced daily dose, not a collection of separate supplements. The value sits in how the ingredients work together. The aim is living brighter, with balance, energy and a mind that feels clear, steady and ready for whatever comes next. You can see the full formula on the Hoola product page.
Who tends to reach for reishi mushroom supplements?
People whose days feel heavy before they begin. Hoola is built around one duality, calm clarity and energised performance, for people dealing with burnout, emotional load, stress and the need for energy that lasts. It's a supplement for modern lives, busy schedules and high ambition.
Reishi is traditionally used to support healthy immune system function. According to the authors of a 2024 review, one study found that the polysaccharides in reishi mushrooms may help decrease fatigue after exercising. That combination suits anyone who trains hard, works hard and still wants to perform without the crash.
How should you take reishi day to day?
Mix one 10 g scoop into 300 to 400 ml of cold water, each morning. There is no half serve, no double serve and no weekly total. Hoola is one 10 g scoop a day. Take it in the morning or early afternoon, and avoid taking it close to bedtime because of the caffeine.
Reishi on its own is usually taken differently. As a tea, you stir half to one teaspoon of reishi powder into a cup of hot water or broth, and simmer gently for 10 to 15 minutes for a fuller extraction. The flavour is earthy and slightly bitter, pairing well with honey, cacao or chai spices, and a fine powder mixes into coffee, tea, smoothies, soups and broths. One scoop of cold water is faster.
The arc is gradual and honest. Adaptogens may take four to six weeks for their full benefits. The 150 g pouch is two weeks, so you can start there and see how you feel. Consistency over intensity: most of our customers feel the biggest benefits with consistency. More on how the formula works together sits on our blog.
Frequently asked questions
What is a reishi mushroom supplement good for?
A reishi mushroom supplement supports healthy sleep patterns and relaxation without sedation, supports the body's natural response to everyday stress, supports immune system function and supports emotional wellness. It's thought to have some effects on the immune system, and it has been used to help enhance the immune system, reduce stress, improve sleep and lessen fatigue. Researchers are still examining the chemical makeup of the mushroom to better understand how and whether it works for each of these things.
What is the difference between reishi powder and a reishi extract?
Powder is the whole mushroom milled; an extract concentrates specific compounds out of it.
Hoola uses a Ganoderma lucidum fruiting body extract at 400 mg per gram dry equivalent, 4,000 mg dry equivalent per 10 g serve.
What should you look for when comparing reishi mushroom supplements?
Look for the part of the mushroom used, the exact quantity, and where it's tested. Quality and active ingredients in supplements may vary widely, and while laboratory and animal studies give encouraging insights, human studies remain limited and often vary in outcomes. That makes disclosure the deciding factor. We are transparent about what is inside. Every ingredient is delivered at a clinically efficacious dose, and every quantity is published, per gram and per serve.
Can you get reishi from food instead of a supplement?
Reishi is cultivated and sold as a food, but it may be tough and bitter, so it rarely turns up on a plate the way other mushrooms do. Growing it takes patience as well, since it can take up to a year for the mushroom to reach maturity. An extract gives you a known quantity in a form you'll actually take every morning.
Always read the label and follow directions for use.
