ReishiMax GLp® (Singapore)

ReishiMax GLp is a standardised Reishi mushroom (Ganoderma lucidum) extract, uniquely formulated to contain both polysaccharides and triterpenes — the two primary categories of bioactive compounds in reishi, and the meaning behind the “GLp” in the product name (Ganoderma Lucidum polysaccharides). Most reishi supplements on the market contain only polysaccharides; ReishiMax captures both compound groups through a proprietary dual-extraction process, delivering immune support and adaptogenic properties backed by over 30 years of reishi research.

What Makes ReishiMax GLp Different

Walk into any TCM shop in Singapore’s Chinatown — Eu Yan Sang, Hock Hua, or the smaller dispensaries along Sago Street — and you will find lingzhi (reishi) products ranging from dried slices to capsules. The fundamental challenge with most of these products is extraction quality: polysaccharides (particularly beta-glucans) are water-soluble and extracted through hot water, while triterpenes (ganoderic acids) are alcohol-soluble and require ethanol extraction. The vast majority of commercial lingzhi products use only hot water extraction, capturing polysaccharides but leaving the triterpenes behind. ReishiMax GLp uses a proprietary dual-extraction process that captures both compound groups — delivering standardised levels of polysaccharides (for immune modulation) and triterpenes (which have been studied for their role in supporting healthy inflammatory response and liver function).

Pharmanex’s reishi is cultivated under controlled conditions, with each batch tested to verify active compound concentrations. This standardisation means every capsule contains a verified, consistent dose — unlike wild-harvested or loosely processed lingzhi where potency varies enormously depending on growing conditions, harvest maturity, and processing methods. Published analytical studies have found that ganoderic acid content in commercial reishi products can vary by 10-fold or more between brands. ReishiMax eliminates this variability. For Singaporeans already familiar with lingzhi through TCM tradition, ReishiMax represents the same revered mushroom delivered with modern pharmaceutical-grade consistency.

Key Ingredients

Reishi Mushroom Extract (Ganoderma lucidum) — Standardised for Polysaccharides: Beta-glucan polysaccharides are the most studied reishi compounds for immune system modulation. They work by activating macrophages, natural killer (NK) cells, and dendritic cells — key components of the innate immune system. Published research in Immunological Investigations and other peer-reviewed journals has demonstrated that reishi polysaccharides can modulate immune cell activity, supporting both immune vigilance and appropriate immune response regulation.

Reishi Mushroom Extract — Standardised for Triterpenes (Ganoderic Acids): Ganoderic acids are unique to the Ganoderma genus and are not found in other medicinal mushrooms. Over 150 individual triterpene compounds have been identified in Ganoderma lucidum. These compounds have been studied for their roles in supporting liver health, modulating inflammatory markers, and contributing to the overall adaptogenic profile of reishi. The bitter taste of high-quality reishi — familiar to anyone who has tried lingzhi tea — comes directly from triterpene content. Higher triterpene concentration correlates with more pronounced bitterness, which is why TCM practitioners traditionally consider bitter lingzhi to be the most potent.

How to Use

Take two capsules twice daily with food (four capsules total per day). Each bottle contains 60 capsules, providing a 15-day supply at the full recommended dose — or a 30-day supply at a maintenance dose of two capsules daily. Many users begin with the full four-capsule daily dose for the first 1–2 months and then reduce to a two-capsule maintenance dose. Reishi’s adaptogenic and immune-modulating effects are cumulative — consistent daily use for at least 4–6 weeks is recommended before evaluating results. Store the bottle in a cool, dry place, tightly sealed. Singapore’s humidity can affect capsule integrity if the bottle is left open or stored in a bathroom cabinet.

Frequently Asked Questions

How is ReishiMax GLp shipped in Singapore?
Orders ship from the official Nu Skin Singapore warehouse. Standard shipping is S$4.99, or free on orders over S$99. Delivery takes 1–3 business days to most Singapore addresses.

How is ReishiMax different from lingzhi I can buy at TCM shops?
Most TCM lingzhi products use only hot water extraction, which captures polysaccharides but misses triterpenes (ganoderic acids). ReishiMax uses a proprietary dual-extraction process that standardises both compound groups. Additionally, each batch is analytically tested for active compound concentration — a level of quality control that is absent from most loose lingzhi or basic capsule products available at TCM retailers.

What does “GLp” stand for?
GLp stands for Ganoderma Lucidum polysaccharides, reflecting the product’s standardisation for polysaccharide content. However, ReishiMax GLp is equally standardised for triterpenes — the name emphasises the polysaccharide component but the dual-extraction formula delivers both.

Can I take ReishiMax with other mushroom supplements?
ReishiMax pairs well with CordyMax Cs-4 (cordyceps) for a dual-mushroom adaptogenic regimen — many users combine both for comprehensive immune and energy support. Reishi and cordyceps have complementary mechanisms of action and a long history of combined use in TCM formulations.

Is ReishiMax suitable for daily long-term use?
Reishi has been consumed continuously for centuries in traditional Chinese and Japanese medicine with an established safety profile. Published systematic reviews have assessed reishi supplementation periods ranging from 4 weeks to over 16 weeks with no significant adverse effects reported. Long-term daily use at the recommended dose is consistent with the traditional and modern usage pattern for this mushroom.
