Can I take Chaga and Maitake together?

Drug interaction guide

Taking chaga and maitake together may increase the risk of your blood sugar dropping too low (hypoglycaemia) or your blood becoming too thin, which can lead to easier bruising or bleeding.

Why this happens

Both chaga and maitake mushrooms have natural properties that can lower blood sugar levels and slow down blood clotting. When used together, these effects can add up (an additive effect), making them stronger than if you took either one alone.

Use this combination with caution. If you have diabetes or take blood-thinning medications (like warfarin or aspirin), you should speak to your doctor before taking these supplements. Monitor your blood sugar levels closely and watch for signs of easy bruising or bleeding gums. Stop taking both at least two weeks before any scheduled surgery.

Kidney disease or history of kidney stones

Chaga is extremely high in oxalates, which can cause permanent kidney damage or acute kidney failure, especially in those with existing renal issues.

Diabetes

Both mushrooms can significantly lower blood sugar levels, increasing the risk of hypoglycaemia (dangerously low blood sugar) if you are taking insulin or other diabetes medications.

Autoimmune diseases (e.g., Lupus, MS, Rheumatoid Arthritis)

Chaga can stimulate the immune system, which may worsen symptoms of autoimmune conditions or interfere with immunosuppressant medications.

Bleeding disorders or upcoming surgery

These mushrooms have anti-platelet effects and can thin the blood. This increases the risk of bruising and excessive bleeding; they must be stopped at least 2 weeks before any scheduled surgery.

Alcohol

Chaga contains high levels of oxalates. Combining it with alcohol may increase the risk of kidney stones or kidney stress, as both substances can affect renal function. Use with caution.
