Mechanism of action:

• Activate macrophages, natural killer cells (NK cells) and T lymphocytes
• Enhance the secretion of cytokines (such as IL-2, IFN-γ)

 

Application:

• Clinical use as adjuvant therapy for cancer
• Improve immunity decline after chemotherapy

2. Anti-tumor activity

 

• Animal experiments show inhibiting tumor growth
• Combination with chemotherapy may improve efficacy by inhibiting tumor angiogenesis

 

3. Metabolic regulation
(1) Blood lipid regulation:

• Eritadenine inhibits HMG-CoA reductase
• Reduce total cholesterol and LDL levels, with a clinical trial reduction of approximately 10-15%

 

(2) Blood sugar management:
Beta-glucan delays glucose absorption

4. Antioxidant and anti-inflammatory
Ingredients: shiitake mushroom extract powder polyphenols

 

Effect:

• Scavenge free radicals
• Inhibit NF-κB pathway and reduce chronic inflammation

5. Bone health

Vitamin D synthesis:

• Ergosterol is converted into vitamin D₂ by UV irradiation
• Improve calcium absorption (good for people with insufficient sun exposure)

 

1. Allergic reaction
High-risk groups: People with fungal allergies

2. Drug interactions
Anticoagulant drugs and immunosuppressants

3. Metabolic burden
The purine concentration of shiitake mushroom extract powder can reach 5-8 times that of fresh mushrooms. The daily intake of gout patients is recommended to be <50 mg.

4. Impact on organ function

• Liver: Long-term high doses may increase ALT/AST
• Kidneys: People with renal insufficiency need to be cautious
