Can I take Reishi and Shiitake together?

Why this happens

Both reishi and shiitake contain compounds that have 'antiplatelet' effects. This means they make the tiny cells in your blood (platelets) less 'sticky', which slows down the formation of blood clots. Taking them together creates an additive effect, further thinning the blood.

What you should do

It is usually fine to take these together in standard food or supplement amounts if you are healthy. However, you should stop taking both at least two weeks before any scheduled surgery. If you take blood-thinning medications (like warfarin, aspirin, or clopidogrel), speak to your doctor before combining these supplements. Watch for unusual bruising, nosebleeds, or bleeding gums.
