Why this happens

Both mushrooms contain bioactive compounds called beta-glucans. These work in a similar way to support immune function without interfering with how the body processes the other.

It is generally safe to take these together. However, as with any supplement, you should start with a small dose to ensure you do not have an individual sensitivity or digestive upset. Always inform your doctor about any supplements you are taking, especially if you are scheduled for surgery or have an autoimmune condition.

Bleeding disorders or surgery

These supplements may slow blood clotting and increase the risk of bleeding. You must stop taking these at least 2 weeks before any scheduled surgery. Use with caution if you are taking blood-thinning medications like warfarin or aspirin.

Diabetes

These supplements can lower blood sugar levels. If you are taking insulin or other diabetes medications, monitor your blood sugar closely as your dose may need adjustment to prevent hypoglycaemia (dangerously low blood sugar).

Auto-immune conditions (e.g., multiple sclerosis, lupus, rheumatoid arthritis)

These supplements can increase immune system activity, which may worsen the symptoms of autoimmune diseases. Avoid use if you have these conditions.

Shiitake dermatitis

Eating raw or undercooked shiitake can cause a severe, itchy skin rash (flagellate dermatitis) that looks like whip marks. Ensure mushrooms are thoroughly cooked.

Alcohol

It is best to avoid or strictly limit alcohol when taking medicinal mushrooms. Both alcohol and certain compounds in these mushrooms are processed by the liver; combining them may increase the strain on your liver or alter how the supplements are metabolised.

General Food Intake

These medicinal mushrooms contain complex polysaccharides (beta-glucans). For the best absorption, it is often recommended to take them on an empty stomach, at least 30 minutes before a meal, or with a small amount of Vitamin C (such as a small glass of orange juice) which may help the body absorb the active compounds.
