Q: What does lentinan do?
A: Lentinan is a potent beta-glucan polysaccharide extracted from Shiitake mushrooms. It is primarily recognized for its role in modulating and strengthening the immune system. It works by activating various immune cells, such as macrophages and natural killer (NK) cells, to help the body defend against pathogens. It is also studied for its potential to support overall cellular health.
Q: What are the side effects of lentinan?
A: When taken at appropriate oral doses, lentinan is generally very well-tolerated. In rare cases, some individuals may experience mild digestive discomfort when first starting supplementation. The more significant side effects reported in medical literature are associated with intravenous administration (not oral supplements), which can include skin reactions and changes in blood pressure.
Q: Is it safe to take mushroom powder every day?
A: Yes, for most people, daily consumption of medicinal mushroom powders (like Reishi, Lion’s Mane, Shiitake) is safe and recommended for cumulative benefits. These powders are considered functional foods and adaptogens. Consistency is key to experiencing their full effects on immune, cognitive, and energy support.
Q: What foods contain lentinan?
A: The primary and most significant dietary source of lentinan is the Shiitake mushroom. Cooking does not destroy this compound, so consuming cooked shiitake mushrooms regularly can provide dietary lentinan.
Q: Who should not take a mushroom supplement?
A: The following individuals should exercise caution or avoid mushroom supplements:
Those with a known allergy to mushrooms or mold.
Individuals with autoimmune diseases (e.g., rheumatoid arthritis, lupus) should consult a doctor, as some mushrooms can stimulate the immune system.
People taking immunosuppressant drugs post-transplant, due to potential interactions.
Those who are pregnant or breastfeeding should seek medical advice first due to limited safety data.
