ReishiMax GLp® Immune Support Supplements (USA)

ReishiMax GLp® — The World's Most Standardized Reishi Mushroom Extract

Reishi mushroom (Ganoderma lucidum) has been called the "mushroom of immortality" in traditional Chinese medicine for over 2,000 years — used by emperors and healers as a tonic for longevity, vitality, and immune strength. Modern science has validated much of this traditional wisdom, identifying the specific compounds responsible for reishi's immune-modulating effects: ganoderic acids (triterpenes) and polysaccharides (beta-glucans). ReishiMax GLp contains the highest standardized levels of both compound groups commercially available in any reishi supplement.

The "GLp" in the name stands for the specific standardization — Ganoderic acids, Lucidenic acids, and polysaccharides. Most reishi supplements standardize for only one of these compound groups (usually just polysaccharides, because they're less expensive to measure). ReishiMax's dual standardization is rare in the industry and provides a more complete reishi benefit profile, as ganoderic acids and polysaccharides activate different aspects of the immune system.

Key Benefits

• Immune Cell Proliferation — Demonstrated in testing to support healthy immune cell proliferation, helping your body maintain a larger, more responsive pool of immune cells ready to respond to threats
• Immune System Modulation — Supports balanced immune function — stimulating underactive responses while helping regulate overactive ones. This modulation is distinct from simple immune stimulation and is why reishi is classified as an immunomodulator, not just an immune booster
• Highest Standardized Actives — Contains the highest commercially available levels of ganoderic acids (triterpenes) and polysaccharides (beta-glucans), the two compound groups responsible for reishi's documented immune benefits
• Adaptogenic Resilience — Reishi's triterpenes support your body's resilience to physical, environmental, and emotional stress — helping maintain baseline immune function during demanding periods
• Antioxidant Support — Triterpene compounds in reishi provide antioxidant defense that complements its immune-modulating activity

Key Ingredients

ReishiMax's formula is a concentrated, standardized extract of Ganoderma lucidum — not dried mushroom powder, not a basic water extract, but a multi-step extraction designed to capture both the water-soluble and fat-soluble bioactive compounds.

• Ganoderic Acids (Triterpenes) — Fat-soluble compounds unique to reishi that modulate immune cell activity, support healthy inflammatory response, and provide antioxidant protection. Research published in International Immunopharmacology shows ganoderic acids can modulate cytokine production and support natural killer (NK) cell activity. ReishiMax standardizes these at the highest commercially available level
• Polysaccharides (Beta-1,3/1,6-Glucans) — Water-soluble compounds that stimulate innate immune function by binding to receptors on macrophages and dendritic cells, activating pathogen-recognition pathways. A systematic review in Cochrane Database found consistent evidence that Ganoderma polysaccharides support immune parameters in multiple clinical populations
• Lucidenic Acids — Additional triterpene compounds present in reishi that complement ganoderic acid activity and contribute to the extract's overall immunomodulatory profile

How Nu Skin's Approach Differs

The reishi supplement market is filled with products containing dried mushroom powder — essentially ground-up mushroom bodies with minimal extraction. These products contain relatively low concentrations of active compounds, variable quality, and often include non-active mycelium or grain substrate. ReishiMax uses a multi-step extraction process to concentrate and standardize both ganoderic acids and polysaccharides.

The dual standardization is the real differentiator. Most competitors standardize only for polysaccharides (because the test is simpler and less expensive). But ganoderic acids are responsible for many of reishi's most important immune-modulating effects — skipping them means missing half the benefit profile. ReishiMax is one of very few products that standardizes both, at verified levels.

Under the 6S Quality Process, each batch is tested for active compound content, heavy metals (important for mushroom products, as fungi can accumulate contaminants from growing substrates), microbial contamination, and identity verification to confirm the correct Ganoderma species is used.

How It Compares

How to Use

Take the recommended daily dose with food. Consistent daily use is more effective than sporadic supplementation — immune system support is an ongoing process, not a quick fix. Most people notice improved resilience (fewer sick days, faster recovery from illness) within 4-6 weeks of consistent use. During cold and flu season or periods of high stress, maintaining your daily dose is especially important. The 60-capsule bottle provides a 30-day supply.

Who Should Consider This Product

ReishiMax is well-suited for adults who want targeted immune support beyond what a multivitamin provides — particularly those with demanding lifestyles, frequent travel, seasonal immune challenges, or high-stress occupations that tend to suppress immune function. It's also relevant for anyone interested in medicinal mushroom supplementation who wants the highest-quality, most standardized option available. Not recommended for people with mushroom allergies. If you're on immunosuppressant medications (organ transplant recipients, autoimmune disease treatment), consult your healthcare provider — immune-modulating supplements may interfere with these medications.

Frequently Asked Questions

Q: How is ReishiMax different from less expensive reishi supplements?

A: Most budget reishi products use dried mushroom powder or mycelium grown on grain — containing low, unstandardized levels of active compounds (and sometimes significant grain filler). ReishiMax uses a concentrated dual extraction standardized for both ganoderic acids and polysaccharides at the highest commercially available levels. The active compound content per capsule is dramatically higher.

Q: Can I take this during cold and flu season as a preventive?

A: Yes — that's one of the most common use cases. Starting before cold and flu season gives your immune system time to build up the enhanced surveillance and response capacity that consistent reishi supplementation supports. Daily use throughout the season provides ongoing protection.

Q: Can I stack ReishiMax with Tegreen 97 for immune support?

A: Yes, they complement each other well. ReishiMax modulates immune cell function through mushroom-derived compounds. Tegreen 97 provides antioxidant defense through green tea catechins, protecting immune cells from oxidative damage. Different mechanisms, additive benefits.

Q: How long should I take this supplement?

A: Reishi has been used safely for thousands of years in traditional medicine, and modern research supports long-term use. ReishiMax is designed for ongoing daily supplementation, not short-term use. Immune support is an ongoing process — your immune system benefits from consistent nutritional support year-round.

Q: Are there any drug interactions I should know about?

A: Reishi may interact with blood-thinning medications (due to its antiplatelet activity), immunosuppressants, and some blood pressure medications. If you're on any prescription medications — particularly anticoagulants, immunosuppressants, or antihypertensives — consult your healthcare provider before starting reishi supplementation.
