Why It Works
Benefits
LEM delivers comprehensive support through its unique extraction and cultivation process.
Supports Immune Function
LEM contains beta-glucans, polysaccharides that interact with immune cells in the gut-associated lymphoid tissue (GALT). Research suggests these compounds help train immune cells, supporting appropriate immune responses without overstimulation.
Research-backed ingredientProvides Antioxidant Protection
LEM's lignin compounds and other antioxidants help protect cells from oxidative damage, supporting the integrity of immune tissues. Oxidative stress can compromise immune cell function.
Contains natural antioxidantsSupports Gut-Immune Connection
Approximately 70% of immune tissue resides in the gut. LEM's prebiotic-like compounds support the gut environment where much of immune system activity occurs.
Supports gut healthUnique Bioavailable Compounds
Unlike simple dried shiitake powder, LEM undergoes enzymatic extraction that breaks down cell walls and releases bioactive compounds including water-soluble lignin and arabinoxyloglucan polysaccharides.

How It Works
Understanding how LEM supports your body's natural immune processes.
LEM Production Process (4-Month Cultivation)
- Medium Preparation: Bagasse (sugarcane fiber) and rice bran form the solid cultivation medium
- 4-Month Cultivation: Mycelia grow at room temperature, during which enzyme reactions and self-digestion occur
- Extraction: The fully cultivated medium is placed in extraction tanks for self-digestion
- Filtration: 0.45 micron membrane filter ensures purity
- Concentration and Drying: Final powder is produced
This extended cultivation allows over 100 enzymes to create unique compounds.
Components Born from Long-Term Cultivation
This is only obtained through a continuous reaction of over a hundred kinds of enzymes produced by the mycelium itself. This cannot be obtained through liquid cultivation, which is quickly cultivated in a short period.
LEM as a Fermented Food
It is rich in water-soluble lignin and polysaccharides, drawing a clear distinction from health supplements using general mushrooms.

Ingredient Research Highlights
BETA-GLUCANS
Beta-glucans are polysaccharides found in shiitake mushrooms that have been studied for their effects on immune function. Research suggests they interact with immune cells and may help modulate immune responses.
Published research on mushroom polysaccharidesWATER-SOLUBLE LIGNIN
LEM contains water-soluble lignin compounds that are unique to its extended cultivation process. Lignin typically exists as insoluble fiber in plants, but LEM's enzymatic process creates a water-soluble form with potential bioactive properties.
Noda Shokukin research documentationARABINOXYLOGLUCAN
This special polysaccharide is formed during LEM's 4-month cultivation process through the action of over 100 enzymes. It represents a unique compound not found in standard dried shiitake products.

Questions
Frequently Asked Questions
LEM is extracted from shiitake mycelia grown on solid medium, rich in beta-glucans and lignin compounds. AHCC is derived from shiitake mycelia grown in liquid culture, emphasizing alpha-glucans with lower molecular weight.
Both have been studied for immune support, with AHCC having more research specifically on immune cell activation.
Most shiitake products use dried and powdered fruiting bodies (the caps and stems). LEM is extracted from the mycelia - the underground network that absorbs nutrients before the visible mushroom forms.
This difference matters because mycelia contain unique compounds like water-soluble lignin and specific polysaccharide patterns not found in significant amounts in the fruiting body. Additionally, LEM undergoes enzymatic extraction that makes these compounds bioavailable.
Many users report increased energy and improved sense of wellbeing within 2-4 weeks of consistent daily use. For immune support benefits, most research suggests that mushroom beta-glucans require consistent intake over 8-12 weeks to show measurable effects.
We recommend committing to at least 3 months of daily use before evaluating results.
First, the four-month cultivation period significantly increases production time and costs. Second, the proprietary enzymatic extraction process requires specialized equipment and expertise developed over 45 years. Third, Noda Shokukin maintains Japanese GMP manufacturing standards with comprehensive testing protocols.
When evaluating cost, consider the daily price and compare the extraction quality rather than just price per gram.
The individual packaging protects the powder from moisture, making it convenient to take with you while maintaining maximum nutritional potency.
It dissolves easily in warm water or can be taken directly with a glass of water.
The beta-glucans and unique polysaccharides in shiitake mycelia interact with immune cells to help support appropriate immune responses. Many people use it as part of their daily wellness routine for year-round immune resilience.
Individuals taking immunosuppressants or blood-thinning medications should consult their physician before use. Pregnant and nursing women should also consult their doctor before starting any new supplement.
