ReishiMax GLp - Nu Skin Pharmanex (UK)

ReishiMax GLp is Pharmanex's standardised reishi mushroom (Ganoderma lucidum) extract, using a proprietary cracked spore technology that makes the active compounds — particularly the triterpenoids and polysaccharides — significantly more bioavailable than standard reishi preparations. At £95.00, it's a premium immune and vitality supplement, priced above standard reishi products you'll find in Holland & Barrett because the extraction technology produces a more potent and consistent product. Reishi has over 2,000 years of traditional use and a growing body of modern research — including studies on immune modulation, antioxidant activity, and stress adaptation published in peer-reviewed journals.

What Makes ReishiMax GLp Different

The "GLp" designation refers to Ganoderma Lucidum polysaccharides — the standardised active fraction. Most reishi supplements use whole mushroom powder or basic hot-water extracts, which contain the active compounds but in variable and often low concentrations. ReishiMax uses cracked spore technology because reishi spores contain the highest concentration of triterpenoids (the compounds primarily responsible for immune-modulating effects), but the spore wall is extremely hard and virtually indigestible intact. The cracking process breaks the cell wall without damaging the active compounds, increasing bioavailability substantially.

A 2012 Cochrane review examined Ganoderma lucidum for cancer treatment support, noting evidence of immune function enhancement, though concluding that more high-quality trials were needed. More recent research has focused on reishi's effects on NK (natural killer) cell activity and T-cell modulation. A study in Immunological Investigations (Gao Y, et al., 2003;32(3):201-215, PMID: 12916709) found that Ganoderma lucidum polysaccharides enhanced immune cell markers in advanced-stage cancer patients over 12 weeks.

Key Ingredients

Ganoderma lucidum Polysaccharides (Cracked Spore) — Beta-glucans and other polysaccharides that modulate immune function by activating macrophages, NK cells, and dendritic cells. The cracked spore format provides significantly higher bioavailability than whole mushroom or uncracked spore preparations.

Triterpenoids (Ganoderic Acids) — Bitter compounds unique to reishi that have demonstrated anti-inflammatory and hepatoprotective effects in laboratory and animal studies. Ganoderic acids also support the Nrf2 antioxidant pathway — complementary to R² Night's broccoli seed extract through a different activation mechanism.

Standardised Extract — Each capsule is standardised to guaranteed levels of both polysaccharides and triterpenoids, verified through Pharmanex's 6S Quality Process. This consistency is the main differentiator from non-standardised reishi products, which can vary dramatically in active compound content between batches.

How to Use

Take 2 capsules twice daily with meals, totalling 4 capsules per day. The 120-capsule bottle provides a 30-day supply. Reishi is an adaptogen — its effects build over time and are most apparent during periods of stress or immune challenge. Most users report noticeable benefits from week 4-6, though the immune-modulating effects are working from day one even if not perceptible. During the British autumn and winter — when seasonal illness circulates and the cold, damp climate puts additional stress on the immune system — ReishiMax provides targeted support.

Who Is This For

Adults looking for evidence-based immune support beyond basic vitamin C. Particularly relevant during British autumn and winter when cold and flu circulate widely, for people working in shared offices or commuting on public transport (high pathogen exposure environments), and for anyone under chronic stress — which suppresses immune function. Also used by people interested in traditional medicine-backed wellness support who want a standardised, quality-controlled product rather than variable-quality mushroom powders from Amazon.

Frequently Asked Questions

Can I buy ReishiMax without signing up?
Yes. NuBest Skin sells it directly — no Nu Skin membership or account required. Ships from the official UK warehouse.

How does this compare to reishi supplements in Holland & Barrett?
Most high-street reishi products use whole mushroom powder or basic extracts without spore cracking or standardisation. ReishiMax uses cracked spore technology for higher bioavailability and standardises each capsule to guaranteed polysaccharide and triterpenoid levels. The active compound content per capsule is measurably higher and more consistent.

Can I take this alongside LifePak+ and R²?
Yes. ReishiMax's immune-modulating compounds don't conflict with multivitamin or gene expression supplements. The combination provides broad nutritional coverage (LifePak+), cellular energy and detoxification (R²), and targeted immune support (ReishiMax) — three complementary mechanisms.

Important Information

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the recommended daily intake. Keep out of reach of young children. Store in a cool, dry place.

If you are pregnant, breastfeeding, taking immunosuppressant medication, blood thinners, or under medical supervision, consult your GP before use. Reishi may interact with anticoagulant medications.
