10 Best Reishi Supplements (2026) Reviewed
Reishi mushroom (Ganoderma lucidum) has been revered in traditional Eastern medicine for over 2,000 years, earning names like “Mushroom of Immortality” and “Spiritual Potency Mushroom.” Modern research suggests this adaptogenic fungus may support immune function, stress response, sleep quality, and overall vitality through its unique combination of beta-glucans and triterpenes.
However, the supplement market is flooded with reishi products of vastly different quality. The key differentiators come down to whether the product uses fruiting body (the actual mushroom) versus mycelium grown on grain, the extraction method used, and whether beta-glucan content is verified. Fruiting body extracts typically contain higher concentrations of beneficial compounds, while mycelium-on-grain products may contain significant amounts of starch filler.
After researching dozens of reishi supplements, analyzing third-party testing results, and reviewing ConsumerLab evaluations, we’ve identified the top products across different formats and price points to help you find the right reishi supplement for your needs.

Best by Type/Form
Capsules
Capsules offer the most convenient way to take reishi with consistent dosing. Look for products that specify fruiting body extract rather than mycelium-on-grain, and check for verified beta-glucan content. Capsules are ideal for those who want a quick, taste-free option that’s easy to incorporate into daily routines. The main tradeoff is that capsules typically cost more per serving than powders.
Powder
Reishi powder provides flexibility in dosing and can be added to coffee, tea, smoothies, or recipes. Powder form often offers better value per serving and allows you to adjust your dose based on your needs. The earthy, slightly bitter taste may not appeal to everyone, though it blends well with chocolate or coffee flavors. Powder is best for those who want versatility and don’t mind measuring doses.
Tinctures/Liquid Extracts
Liquid extracts may offer faster absorption than capsules or powder since they bypass the digestive breakdown process. They’re also easy to add to beverages. However, alcohol-based tinctures have a strong taste that some find unpleasant. Tinctures work well for those who have difficulty swallowing pills or prefer rapid absorption.
Liquid Phyto-Caps
These capsules contain liquid extract rather than dry powder, potentially offering better absorption while maintaining capsule convenience. They’re typically more concentrated, requiring only one capsule per day. The premium format comes at a higher price point but may be worth it for those seeking both convenience and enhanced bioavailability.

Buying Guide: What to Look For
Fruiting Body vs. Mycelium
The most important distinction in reishi supplements is whether they’re made from fruiting body (the actual mushroom) or mycelium (the root-like network, often grown on grain). Fruiting body extracts typically contain higher concentrations of beta-glucans and triterpenes—the compounds responsible for reishi’s benefits. Mycelium-on-grain products contain starch from the growing substrate, diluting the active compounds. Look for labels that specify “fruiting body” or “100% mushroom.”
Beta-Glucan Content
Beta-glucans are the primary active polysaccharides in reishi that support immune function. Quality supplements will list verified beta-glucan content, typically 20-30% or higher for concentrated extracts. Be wary of products that only list “polysaccharides” without specifying beta-glucans, as this can include starch (alpha-glucans) from grain fillers.
Triterpene Content
Triterpenes (including ganoderic acids) are unique to reishi and contribute to its adaptogenic and calming properties. These compounds require alcohol extraction, so dual-extracted products that use both hot water and alcohol will capture both beta-glucans (water-soluble) and triterpenes (alcohol-soluble). Look for products that specify triterpene content if stress support or relaxation is your primary goal.
Third-Party Testing
Reputable brands conduct third-party testing to verify potency and screen for contaminants like heavy metals, pesticides, and microbial contamination. Mushrooms are bioaccumulators, meaning they absorb substances from their growing environment, making purity testing especially important. Look for NSF certification, COA (Certificate of Analysis) availability, or ConsumerLab verification.
Organic Certification
USDA Organic or CCOF certification ensures the mushrooms were grown without synthetic pesticides or fertilizers. While not strictly necessary for efficacy, organic certification provides additional assurance about growing practices and reduces potential contaminant exposure.
Red Flags to Avoid
- Labels that don’t specify fruiting body or mycelium source
- “Proprietary blend” without ingredient amounts
- No beta-glucan content listed
- Unrealistic health claims or “cure” language
- No third-party testing or quality certifications
- Unusually low prices that suggest poor quality ingredients
How to Take Reishi
Recommended Dosage
Research studies typically use 1.5-9 grams of reishi powder or 1-2 grams of extract daily. Most commercial supplements provide 500-1,500mg of extract per serving, which falls within effective ranges. Start with the manufacturer’s recommended dose and adjust based on your response.
Timing
Reishi’s calming, adaptogenic properties make it well-suited for evening use, potentially supporting relaxation and sleep quality. However, some people take it in the morning for stress adaptation throughout the day. Experiment to find what works best for your body and goals.
With or Without Food
Reishi can generally be taken with or without food. Some people find it easier on the stomach when taken with meals, while others prefer it on an empty stomach for potentially faster absorption. Powder forms mix well into hot beverages like tea, coffee, or hot chocolate.
Duration and Cycling
Reishi’s benefits typically build over time with consistent use. Many practitioners recommend taking reishi daily for several weeks to months to experience its full adaptogenic effects. Some people cycle on and off (such as 8 weeks on, 2 weeks off), though this isn’t strictly necessary. Consult with a healthcare provider for personalized guidance on long-term use.
Potential Benefits
Immune Function Support
Beta-glucans in reishi may help modulate immune system activity. Research published in journals like the Journal of Ethnopharmacology suggests reishi polysaccharides may support healthy white blood cell function. However, most studies use isolated compounds at higher doses than typical supplements, so real-world effects may vary.
Stress Adaptation and Mood
As an adaptogen, reishi may help the body respond to stress more effectively. Triterpenes in reishi have been studied for their potential effects on the central nervous system. Some users report improved mood, reduced anxiety, and better stress resilience, though rigorous clinical trials in humans are limited.
Sleep Quality
Traditional use of reishi includes promoting calm and restful sleep. While scientific evidence is preliminary, some small studies and anecdotal reports suggest reishi may help improve sleep quality, particularly in people experiencing stress-related sleep difficulties.
Cardiovascular Support
Some research suggests reishi may support healthy blood pressure and cholesterol levels already within normal ranges. These potential benefits are attributed to triterpenes and other compounds, though more research is needed to confirm effects in humans.
Antioxidant Properties
Reishi contains various compounds with antioxidant activity that may help protect cells from oxidative stress. This contributes to its traditional reputation as a longevity-supporting tonic.
Safety Considerations
Potential Side Effects
Reishi is generally well-tolerated, but some people may experience digestive upset, dry mouth, or skin rashes. These effects are typically mild and resolve with dose reduction or discontinuation. Start with a lower dose to assess tolerance.
Who Should Avoid Reishi
- People with mushroom allergies
- Those taking blood thinners (reishi may have antiplatelet effects)
- People with low blood pressure (reishi may lower blood pressure)
- Those scheduled for surgery (discontinue 2 weeks before due to potential bleeding risk)
- Pregnant or breastfeeding women (insufficient safety data)
- People with autoimmune conditions (due to immune-modulating effects)
Drug Interactions
Reishi may interact with anticoagulants, antiplatelet drugs, antihypertensive medications, and immunosuppressants. Always consult with a healthcare provider before starting reishi if you take any medications or have underlying health conditions.
Liver Considerations
Although rare, cases of liver injury have been reported with reishi use. People with existing liver conditions should use caution and consult with their healthcare provider. Discontinue use and seek medical attention if you experience symptoms like yellowing skin, dark urine, or abdominal pain.
Frequently Asked Questions
How long does it take for reishi to work?
Reishi’s effects typically build over time with consistent use. Some people notice improved sleep or mood within the first few weeks, while immune and adaptogenic benefits may take 1-2 months of daily use to become apparent. Individual responses vary based on dosage, product quality, and personal factors.
Is fruiting body really better than mycelium?
Fruiting body extracts contain higher concentrations of beta-glucans and triterpenes compared to mycelium-on-grain products. However, mycelium may contain different beneficial compounds. Most research supporting reishi’s benefits has used fruiting body preparations. For maximum potency, fruiting body extracts are generally preferred.
Can I take reishi every day?
Yes, reishi is traditionally taken daily and is generally considered safe for long-term use. As an adaptogen, its benefits typically accumulate with regular use. Some people cycle their use, but this isn’t strictly necessary for most users.
Should I take reishi in the morning or at night?
Reishi is commonly taken in the evening due to its calming properties and potential sleep benefits. However, it doesn’t cause drowsiness in most people, so morning use for stress adaptation throughout the day is also appropriate. Experiment to find what timing works best for you.
What’s the difference between red reishi and other colors?
Red reishi (Ganoderma lucidum) is the most studied and commonly used variety. Other species like black reishi or purple reishi exist but have less research supporting their benefits. Most quality supplements specify they use Ganoderma lucidum or red reishi.
Can I take reishi with other mushroom supplements?
Yes, reishi is commonly combined with other medicinal mushrooms like lion’s mane, cordyceps, or chaga. Each mushroom has different primary benefits, so combinations can provide complementary effects. Many brands offer mushroom complex products for this purpose.
How do I know if my reishi supplement is working?
Effects can be subtle and may include improved sleep quality, better stress resilience, more stable mood, or fewer minor illnesses. Keeping a wellness journal can help track changes over time. Note that some benefits (like immune support) may not have obvious day-to-day symptoms.
Is reishi safe to take with medications?
Reishi may interact with blood thinners, blood pressure medications, and immunosuppressants. Always consult with your healthcare provider before combining reishi with any medications, especially if you have underlying health conditions.
Why do some products list polysaccharides instead of beta-glucans?
“Polysaccharides” is a broader category that includes both beneficial beta-glucans and less desirable alpha-glucans (starches). Products made from mycelium-on-grain may have high polysaccharide counts that are mostly starch. Look specifically for beta-glucan content for a more accurate measure of active compounds.
Does reishi have caffeine or stimulant effects?
No, reishi contains no caffeine and has no stimulant properties. It’s actually known for its calming, rather than energizing, effects. This makes it suitable for evening use and for people sensitive to stimulants.
