Can I take Lions mane and Reishi together?

Why this happens

Both supplements contain bioactive compounds (like polysaccharides) that can interfere with how blood clots and how the body processes glucose. Combining them may have an additive effect on these processes.

How to know if you're having a drug interaction

You may be experiencing an interaction between lions mane and reishi if:

• You develop digestive issues, such as nausea, bloating, diarrhoea, or stomach discomfort.

• You feel unusually tired, dizzy, or weak after taking both supplements.

• You notice headaches or flu-like symptoms, possibly due to immune system stimulation.

• You experience allergic reactions, such as itching, rash, or swelling.

• You have increased bruising or bleeding, especially if taking blood-thinning medicines.

• Symptoms appear shortly after starting or increasing the dose of either supplement.
  

What you should do

It is usually fine to take these together. However, if you are scheduled for surgery, stop taking both at least two weeks beforehand.

If you have diabetes or take blood-thinning medication (such as warfarin or aspirin), monitor your blood sugar and watch for unusual bruising or bleeding.

Consult your GP before starting this combination if you have a pre-existing medical condition.

If you have any of the above symptoms, you should:

• Stop taking the supplements and see if your symptoms improve.

• Speak to your GP or pharmacist for personalised advice.

• Seek urgent medical help if you develop severe allergic reactions, such as swelling of the face or difficulty breathing.

• Tell your healthcare professional about all medicines and supplements you are taking.

• Avoid restarting the supplements until a healthcare professional confirms it is safe.
