Introduction To Shiitake

Shiitake Mushroom – Detailed Health Benefits

⸻

100% Irish Grown Shiitake

Immune System Support

Key Compounds: Lentinan, beta-glucans, polysaccharides

• Lentinan, a powerful beta-glucan, stimulates T-cells, natural killer (NK) cells, and macrophages, enhancing the body’s innate and adaptive immune responses.

• Shiitake extracts are used in Japan as adjunct therapy for cancer patients due to their ability to increase survival rates and reduce chemotherapy side effects.

• Regular consumption can

improve the body’s resistance to infections, colds, and flu.

Study: Lentinan has been shown to prolong survival in patients with gastric cancer and improve immune function.

Cardiovascular Health

Key Compounds: Eritadenine, sterols, beta-glucans

• Eritadenine is known to help lower LDL (bad) cholesterol by modifying how the liver processes fats.

• Shiitake mushrooms also contain sterols and beta-glucans, which block the absorption of cholesterol in the digestive tract.

• They may help lower blood pressure, reduce atherosclerosis risk, and promote vascular elasticity.

 Study: Animal trials have shown eritadenine significantly reduces plasma cholesterol levels in hypercholesterolemic rats.

Anti-Inflammatory Properties

Key Compounds: Phenolic acids, terpenoids, beta-glucans

• Shiitake compounds modulate inflammatory pathways, such as NF-κB and COX-2, helping manage inflammation without suppressing immunity.

• Beneficial for people with autoimmune diseases, arthritis, eczema, and chronic gut inflammation.

 Study: Shiitake-fed mice showed decreased C-reactive protein (CRP), a key marker of systemic inflammation.

Antimicrobial & Antiviral Effects

Key Compounds: Lentinan, oxalic acid, eudesmane-type sesquiterpenoids

• Extracts exhibit activity against Staphylococcus aureus, E. coli, Candida albicans, and certain viruses.

• Traditionally used to support the body in fighting viral infections, including influenzaand herpes viruses.

 Study: In vitro research confirms lentinan inhibits viral replication and promotes interferon production.

Skin, Hair & Collagen Support

Nutrients: Copper, selenium, zinc, B2, B3, B5

• Copper is essential for collagen synthesis and maintaining skin elasticity.

• Selenium and zinc protect against oxidative stress and promote wound healing.

• B-complex vitamins in Shiitake improve skin texture, reduce dryness, and may support hair growth.

Cognitive & Mood Support

Key Compounds: Ergothioneine, B-vitamins, antioxidants

• Shiitake is a natural source of ergothioneine, a unique amino acid antioxidant that crosses the blood-brain barrier and reduces oxidative stress in the brain.

• Supports memory, focus, and clarity, and may have neuroprotective effects long term.

Energy, Metabolism & Gut Health

• Rich in dietary fiber and digestive enzymes, Shiitake supports gut microbiota balance.

• Enhances mitochondrial energy production via B-vitamins, especially niacin (B3) and pantothenic acid (B5).

• Can help combat fatigue, support adrenal function, and aid weight regulation.

Freshly Harvested Shiitake

Cancer-Supportive Properties

• Lentinan is studied as an immunotherapy agent in various cancers (gastric, colorectal, lung).

• May improve quality of life, reduce tumor growth, and increase chemotherapy tolerance.

 Japan: Lentinan is approved as an anti-cancer drug and covered under national insurance in cancer protocols.
