Both Lion's Mane and Reishi mushrooms have natural blood-thinning properties. Taking them together might increase the risk of bruising or bleeding, especially if you are already taking blood-thinning medication or have an upcoming surgery. Additionally, both may lower blood sugar levels, which could lead to feeling dizzy or shaky if levels drop too low.
In this article:
It is usually fine to take Lions Mane and Reisha together. However, using both might increase the risk of bruising or bleeding, especially if you are already taking blood-thinning medication or have an upcoming surgery.
Stop taking both supplements at least two weeks before any planned surgery.
If you take medicine for diabetes, blood pressure, or blood thinners (such as warfarin or aspirin), talk to your doctor before using them together.
Watch for signs of low blood sugar or unusual bruising.
Why this happens
Both supplements can slow down blood clotting (antiplatelet effect) and improve how the body uses insulin (hypoglycaemic effect). When used together, these effects can add up, making them stronger than when taken alone.
