Best Reishi Mushroom Supplements: 8 Brands Tested & Reviewed (2026)

Last Updated: December 18, 2025 | We review supplements independently and only recommend products we’ve personally tested or researched thoroughly.

---

After spending months testing and researching reishi mushroom supplements, I’ve learned one frustrating truth: most reishi products on the market aren’t worth your money.

Many brands use cheap mycelium grown on grain (basically rice powder with traces of mushroom), low-potency extracts, and misleading labels. The result? You’re paying premium prices for supplements that deliver minimal benefits.

But here’s the good news: there ARE high-quality reishi supplements out there—you just need to know what to look for. In this comprehensive review, I’ll share the 8 best reishi mushroom supplements I’ve tested based on purity, potency, third-party testing, and real user results.

Whether you’re taking reishi for better sleep, stress relief, or immune support, this guide will help you find the right supplement without wasting money on duds.

What Makes a Great Reishi Supplement?

Before we dive into the reviews, let’s talk about what separates quality reishi supplements from garbage. Here’s what I looked for when testing these products:

1. Fruiting Body vs. Mycelium (THE Most Important Factor)

Always choose fruiting body extracts. The fruiting body is the actual mushroom cap—the part that contains the highest concentration of beneficial compounds like beta-glucans and triterpenes.

Many cheap supplements use mycelium grown on grain, which means you’re mostly getting starch and grain fillers with minimal active mushroom compounds. ConsumerLab cautions consumers that some brands position themselves as mushroom products when, in fact, they’re mostly made of mycelium-on-grain, which is misleading.

Red flag: Labels that say “myceliated biomass” or “mycelium/fermented rice biomass”

Green flag: “100% fruiting body” or “fruiting body extract”

2. Beta-Glucan Content

Beta-glucans are the immune-supporting polysaccharides that make reishi effective. A good product should list 30% or more beta-glucans, as this is the compound linked to immune and gut health benefits.

If a supplement doesn’t disclose beta-glucan content, that’s a major red flag. They’re probably hiding low concentrations.

Look for: 25-30%+ beta-glucans listed on the label

3. Dual Extraction Process

Some of reishi’s most powerful compounds are water-soluble (like beta-glucans), while others—like triterpenoids—require alcohol extraction, which is why the best supplements use a dual extraction process.

Without both extraction methods, you’re missing out on significant benefits.

Look for: “Dual-extracted” or “Hot water + ethanol extract” on the label

4. Extract Ratio

The extract ratio tells you how concentrated the supplement is. An 8:1 ratio means 8 pounds of raw mushroom were used to create 1 pound of extract.

Look for: At least 4:1 ratio, preferably 8:1 or 10:1

5. Third-Party Testing

Mushrooms naturally absorb whatever’s in their growing environment—including pesticides, heavy metals, or other contaminants. Third-party testing ensures your supplement is pure and safe.

Must-haves:

• Heavy metal testing
• Contaminant screening
• Potency verification
• Certificate of Analysis (COA) available

6. Certifications

Bonus points for:

• USDA Organic
• Non-GMO Project Verified
• GMP-certified manufacturing
• Vegan/Gluten-free (if relevant to you)

How to Take Reishi Supplements for Best Results

Dosage Guidelines

Standard dose: 1-3 grams of reishi extract daily

For specific goals:

• Sleep improvement: 1-2 grams, taken 2-4 hours before bed
• Immune support: 1.5-3 grams, taken in morning or split dose
• Stress reduction: 1.5-2 grams, split between morning and evening

Timing Recommendations

For sleep and stress relief:

• Take 2-4 hours before bedtime
• Allows effects to build gradually
• Promotes natural sleep-wake cycle

For immune and general wellness:

• Morning with breakfast
• Or split dose (morning + evening)
• Consistency matters more than exact timing

With or Without Food?

Either works, but:

• With food: Better tolerated, less digestive upset
• Empty stomach: Potentially faster absorption

Start with food, then experiment once your body adjusts.

How Long Until Results?

Timeline:

• Week 1: Subtle relaxation, possible sleep improvements
• Weeks 2-4: Noticeable stress resilience and sleep quality
• Months 2-3: Immune benefits and long-term wellness effects

Important: Take reishi consistently for at least 4-8 weeks before judging effectiveness. This isn’t a supplement that works overnight—it builds benefits over time.

Common Mistakes When Buying Reishi

Mistake #1: Choosing Based on Price Alone

The cheapest option is often low-quality mycelium-on-grain with minimal active compounds. You’re wasting money on rice starch, not mushrooms.

Solution: Set a minimum budget of $20-25/month for legitimate quality.

Mistake #2: Not Checking Beta-Glucan Content

If a label doesn’t list beta-glucan percentage, the company is hiding low concentrations.

Solution: Only buy products that clearly state beta-glucan content (aim for 25-30%+).

Mistake #3: Falling for “Proprietary Blends”

“Proprietary blend” means they won’t tell you exact amounts of each ingredient.

Solution: Demand transparency. Choose brands that list exact amounts.

Mistake #4: Ignoring Extraction Method

Reishi needs both water and alcohol extraction to capture all beneficial compounds.

Solution: Look for “dual-extracted” on the label.

Mistake #5: Expecting Immediate Results

Reishi works gradually over weeks, not hours.

Solution: Commit to 4-8 weeks of consistent use before judging effectiveness.

For most people: Start with Real Mushrooms Reishi Extract
