Can I take Chaga and Cordyceps together?

Why this happens

Both chaga and cordyceps have 'anti-platelet' effects, meaning they slow down blood clotting. When used together, this effect is additive. Additionally, both fungi can mimic or enhance the effects of insulin, leading to a combined lowering of blood glucose.

What you should do

It is generally safe for healthy individuals to take these together in moderate amounts, but you should use caution. If you are scheduled for surgery, stop taking both at least two weeks beforehand. If you take medication for diabetes or blood-thinning drugs (like warfarin or aspirin), speak to your doctor before combining these supplements.

Important precautions

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

Chaga may 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)

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

Bleeding disorders or upcoming surgery

Both mushrooms have significant anti-platelet effects and can increase the risk of bruising and bleeding; they must be stopped at least 2 weeks before any planned surgery.

Food and drink warnings

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.

Caffeine

Cordyceps may have mild stimulant properties and can interact with adenosine receptors. Combining it with caffeine (coffee, tea, energy drinks) may increase heart rate, jitteriness, or palpitations in sensitive individuals.
