Reishi is a medicinal mushroom traditionally used in East Asian medicine, providing potential health benefits like supporting immune function, regulating mood, and improving sleep quality. It is often taken as a tincture, capsule or powder mixed into beverages.
To help you understand more about this intriguing mushroom, we’ve created a guide exploring what Reishi is, the potential health benefits of Reishi mushrooms supported by emerging research, and the best ways to take it. Results of use may vary between individuals, and scientific research on the mushroom is ongoing. This guide aims to outline the current evidence behind Reishi to help you make informed decisions about its use.
What is Reishi?
The Reishi mushroom, scientifically known as Ganoderma lucidum and commonly known as Lingzhi in Chinese medicine, is a functional mushroom native to East Asia. It’s often taken as a tincture, capsules or a powder mixed into beverages.
Some sources suggest that Reishi has been used for medicinal purposes for over 2,000 years. In the wild, it grows in humid, wooded environments, typically on the dried trunks of dead trees, and is considered rare to find naturally.
What makes this mushroom particularly interesting is its reported health benefits. Reishi is known for promoting overall bodily wellbeing and longevity (Kalita et al. 2024). In fact, the Chinese name, ‘Lingzhi’, is associated with spiritual potency and immortality, symbolising long-life and improved vitality.
How does Reishi work?
So, what’s actually happening inside the body when you take Reishi? Research suggests that the Reishi mushroom contains several bioactive compounds: triterpenes, polysaccharides and ganoderic acids.
Reishi mushrooms naturally contain beta-glucans, a type of bioactive polysaccharide found in the cell walls of certain fungi, plants and bacteria. These beta-glucans are among the main compounds studied for their immunity enhancement, antimicrobial, and anti-inflammatory effects.
The Reishi mushroom is also often described as an adaptogen because it may help the body respond more evenly to stress. By supporting the systems involved in the stress response, Reishi is thought to promote balance in key physiological processes, helping support mental resilience and overall physical wellbeing over time.
What is Reishi Good For?
Traditionally valued in East Asian medicine and increasingly studied in modern science, Reishi is linked to a range of potential health benefits, particularly for stress management, immune support, and overall balance. Early research on Reishi is promising, but more human studies are still needed to fully confirm the effects.
1. Sleep Support
- Provides calming effects: In traditional Chinese medicine, the Reishi mushroom has been associated with shen, a concept surrounding the human spirit and emotional balance. It’s said to promote calm, alleviate stress and improve sleep, making it one of the best mushrooms for rest.
- Improves sleep quality and duration: Research suggests that Reishi may help support improved sleep quality. A study carried out in 2012 by Cui et al. found that Reishi extract increased total and non-REM sleep time in rats, supporting its traditional use for promoting restful sleep, though human studies are still limited.
- Reduces cortisol (stress hormone): Reishi’s adaptogenic activity may help lower cortisol levels (Venter et al. 2025). It is also thought to support relaxation by interacting with neurotransmitter systems linked to GABA (the brain’s main calming messenger). By calming the nervous system, Reishi may encourage deeper and more consistent sleep cycles.
For those taking Reishi drops, a standard dual-extraction provides the most potent tinctures, allowing the body to best absorb the mushroom’s properties and maximise these benefits.
2. Stress & Mood Regulation
- Helps regulate the body’s stress response: As an adaptogen, Reishi helps the body respond to stress in a more balanced way. It works with the body’s hormones and nervous system – depending on what your body needs – to support a steadier response to everyday stress.
- Reduces fatigue and anxiety: Research suggests Reishi may be associated with reductions in stress, anxiety, and stress-related fatigue. A 2022 study by Zhang, Y., et al. on mice found that Reishi mushroom helped reduce anxiety and depression-like behaviours caused by early-life stress, likely by lowering inflammation in the body and brain.
- Helps provide mental clarity and alleviates burnout: Traditionally used to “calm the mind,” Reishi is associated with improved focus and mental clarity through supporting nervous-system balance and reducing stress. Because our mood is closely linked to hormonal balance, Reishi is often used during times of increased sensitivity, such as menopause.
3. Immune Health
- Stimulates immune cells: Reishi contains natural compounds called polysaccharides and beta-glucans, which interact with immune cells and help the body maintain healthy immune activity.
- Helps keep the immune system in balance: Rather than overstimulating the immune system, Reishi is valued for its “balancing” effect. It may help calm overactive immune responses while still supporting the body’s natural defences.
- Supports seasonal allergies: Because Reishi can influence inflammation and immune signalling, it’s often used during seasonal changes when allergies flare up.
- Studied as supportive care alongside medical treatments: Reishi has been researched as a supplement alongside some cancer treatments, particularly for immune support. It’s not a treatment, but may help support overall wellbeing when used alongside conventional care. A 2016 Cochrane study looked at Reishi mushrooms alongside conventional cancer treatments. While the study suggested Reishi may support immune activity and was generally well tolerated, the authors concluded that the evidence was not strong enough to support Reishi as a cancer treatment.
4. Antioxidant & Anti-inflammatory Effects
- Helps protect cells from oxidative stress: Oxidative stress happens when harmful molecules build up faster than the body can deal with them, which can cause gradual wear and tear on cells. Reishi contains natural compounds like polysaccharides and triterpenoids, which help neutralise harmful molecules and support a healthier inflammatory balance in the body (Plosca et al., 2025).
- Supports healthy ageing and joint health: By helping reduce oxidative stress and inflammation, Reishi is often used to encourage healthy ageing. Supporting cellular health over time may help maintain vitality, resilience, and overall wellbeing as the body ages. Reishi’s properties may also help promote joint comfort and mobility, particularly during periods of physical strain or age-related changes.
5. Heart & Metabolic Health
- Lowers blood pressure and cholesterol: Some small-scale studies suggest Reishi may help support healthy blood pressure and cholesterol levels, which are important indicators of cardiovascular wellbeing.
- Regulates blood sugar levels: Reishi may play a role in supporting glucose metabolism and insulin sensitivity, which are important for maintaining stable energy levels and long-term metabolic health.
- Liver protection: Some research, including a review by Ploșca et al. (2025), has also suggested that Reishi mushrooms possess liver protection and aid in managing cardiovascular disease and viral infections.
Most current findings are based mainly on small human studies. While results are encouraging, more large-scale, high-quality studies are needed to confirm Reishi’s effects on heart and metabolic health.
Are the benefits of Reishi different for men vs women?
Reishi offers potential benefits for both men and women alike, particularly for relieving stress, immune support, and better sleep. However, differences in hormones and physiology may influence how it supports individual needs.
Reishi is considered a balancing mushroom, so its benefits are often talked about in relation to the specific needs more commonly experienced by each group. Note that research specifically comparing effects by sex or gender is still limited, and more targeted studies are needed.
| Benefits for Women | Benefits for Men |
|---|---|
|
Menopause support, especially for mood: Reishi is commonly used during menopause for its calming, adaptogenic properties. By supporting the body’s stress response, it may help ease mood changes, irritability, and sleep disturbances that may occur during hormonal transitions. |
Improved cardiovascular health: Cardiovascular disease tends to develop earlier and more frequently in men than in women, particularly before midlife. Men are statistically more likely to experience:
Reishi has been studied for its potential role in supporting heart health, including maintaining healthy blood pressure and circulation, key factors for long-term cardiovascular wellbeing in men. |
|
Fatigue reduction: Many women experience ongoing fatigue linked to stress, hormonal shifts, or poor sleep. Reishi’s balancing effects may help support energy and resilience without acting as a stimulant. |
Prostate support: Some early research has explored Reishi’s role in supporting prostate health, particularly through its anti-inflammatory and immune-modulating properties. While findings are promising, more human research is needed in this area. |

Does the Reishi mushroom cause side effects?
While there are studies showing the potential benefits of Reishi, research into the safety of the mushrooms is limited. If you’re planning on taking Reishi as a supplement, it’s vital to check with a medical professional to see if this is appropriate for you as an individual.
Generally, Reishi is well tolerated, with possible side effects being a dry mouth, dizziness or an upset stomach. For those with specific medical needs or conditions, it’s important to take particular care when considering taking any functional mushrooms.
This is particularly important for those who are:
- Taking blood thinners or immunosuppressants: Reishi may affect blood clotting and immune activity, so professional guidance is especially important in these cases.
- Taking prescription medication: Reishi may interact with certain medications by influencing immune or metabolic pathways. A medical professional can advise you on the potential interactions.
- Have food allergies: Anyone with known mushroom allergies should avoid Reishi or use it only under medical guidance.
- Are pregnant or breastfeeding: Due to a lack of safety data in these groups, Reishi is not generally recommended unless advised by a medical professional.
How can you take Reishi?
Reishi mushrooms are available in several different forms, making it easy to choose an option that fits your lifestyle and preferences. Common ways to consume it include tinctures (also known as drops), powders, capsules, and teas, each with its own benefits.
Mushroom tinctures are the most effective for absorption, quality, and are very easy to use. Take 2ml daily, either under the tongue for faster absorption or mixed into a drink like coffee, tea, or water. You can also take it with meals, as some compounds may absorb better with healthy fats. For best results, use it in the morning to support focus, clarity, productivity and calm throughout the day.
