Kan jag ta Maitake och Shiitake tillsammans?

Guide för läkemedelsinteraktioner

Taking maitake and shiitake mushrooms together may increase the risk of bruising or bleeding. Both mushrooms contain natural compounds that can thin the blood and slow down the clotting process. While they are commonly eaten together in food, taking them in concentrated supplement form increases this effect.

For most healthy people eating these mushrooms in normal food amounts, there is no cause for concern. However, if you are taking concentrated supplements, you should be cautious.

Varför detta händer

Both maitake and shiitake mushrooms have 'antiplatelet' properties. This means they make the tiny cells in your blood (platelets) less 'sticky', which makes it harder for your blood to form clots. When used together, this effect can be stronger.

Stop taking these supplements at least two weeks before any scheduled surgery.

If you are already taking blood-thinning medications (such as warfarin eller aspirin), speak to your doctor before combining these supplements.

Hur man vet om du har en läkemedelsinteraktion

You may be experiencing an interaction between maitake and shiitake mushrooms if:

  • You took large amounts of both together (especially as supplements).

  • You feel sick (nausea), have diarrhoea, or an upset stomach.

  • You feel dizzy or weak, especially if you have diabetes (they can lower blood sugar).

  • You notice easy bruising or bleeding (they may affect blood clotting).

  • You develop rash, itching, or breathing problems (possible allergy).

Vad du bör göra

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

  • Stop taking the mushrooms or supplements.

  • Avoid taking both together unless a healthcare professional advises it.

  • Get urgent help for breathing problems, severe allergic reaction, or heavy bleeding.

  • Speak to a GP or pharmacist if symptoms are mild but don’t go away.

  • Monitor blood sugar if you have diabetes.

Viktiga försiktighetsåtgärder

Blödningsrubbningar eller kirurgi

These supplements may slow blood clotting and increase the risk of bleeding. You must stop taking these at least 2 weeks before any scheduled surgery. Use with caution if you are taking blood-thinning medications like warfarin or aspirin.

Diabetes

These supplements can lower blood sugar levels. If you are taking insulin or other diabetes medications, monitor your blood sugar closely as your dose may need adjustment to prevent hypoglycaemia (dangerously low blood sugar).

Autoimmuna sjukdomar (t.ex. multipel skleros, lupus, reumatoid artrit)

These supplements can increase immune system activity, which may worsen the symptoms of autoimmune diseases. Avoid use if you have these conditions.

Lågt blodtryck (hypotoni)

These supplements may lower blood pressure. If you already have low blood pressure or take medication to control high blood pressure, they could cause your blood pressure to drop too low.

Shiitake dermatitis

Eating raw or undercooked shiitake mushrooms can cause a severe, itchy skin rash known as 'flagellate dermatitis' which looks like whip marks on the skin. Ensure mushrooms are thoroughly cooked to avoid this reaction.

Varningar för mat och dryck

Alkohol

It is best to avoid or strictly limit alcohol when taking medicinal mushrooms. Both alcohol and certain compounds in these mushrooms are processed by the liver; combining them may increase the strain on your liver or alter how the supplements are metabolised.
