Who Shouldn't Drink Mushroom Coffee?

by Steve Maleski, PhD

Are you new to mushroom coffee, particularly Lion's Mane coffee, and interested in trying it out?

Have you heard about its benefits for the brain, body, and overall well-being, and want to add it to your daily routine?

While mushroom coffee has become popular in recent years, there are still some individuals who should avoid it or consult with their doctor before consuming it. Here we will explain who shouldn't drink mushroom coffee and why.

Pregnant or breastfeeding women

If you are pregnant or breastfeeding, you should avoid consuming Lion's Mane coffee or any mushroom supplement. The safety of consuming medicinal mushrooms during pregnancy and breastfeeding is not known, and there is not enough research to ensure its safety. Therefore, it is better to be safe than sorry and avoid mushroom coffee until after pregnancy.


Lion's Mane coffee is not recommended for children under 18 years of age. The dosage, effects, and safety of mushrooms and mushroom supplements on children have not yet been established. Children's immune systems are still developing, so adding mushroom coffee to their diet may cause adverse reactions or negative effects on their well-being.

Allergic to mushrooms

Individuals who are allergic to mushrooms should avoid consuming mushroom coffee or any mushroom-based supplement. The allergic reaction can range from mild to severe and can even cause anaphylaxis, a life-threatening condition.

If you are unsure whether you are allergic to mushrooms, it is recommended to try a small dose first and observe how your body reacts before consuming it on a regular basis.

Undergoing medical treatment

If you are undergoing medical treatment, especially for cancer, you should talk to your doctor first before adding mushroom coffee to your diet.

Some medicinal mushrooms have been shown to have anti-cancer properties, which may interfere with chemotherapy or radiation therapy. Additionally, some mushrooms can interact with medications, particularly blood thinners.

Sensitive Digestive System

If you have a sensitive digestive system or suffer from digestive issues like acid reflux or irritable bowel syndrome (IBS), mushroom coffee may not be suitable for you.

The high acidity and the polysaccharides found in mushrooms may irritate your stomach lining and exacerbate your symptoms. It is important to consult with your doctor or a nutritionist before consuming mushroom coffee to avoid any unwanted side effects.


Mushroom coffee, particularly Lion's Mane coffee, is a beneficial, and tasty drink for many people. Still, there are some individuals who should avoid it or proceed with caution.

Pregnant or breastfeeding women, children, those allergic to mushrooms, people undergoing medical treatment, and those with sensitive digestive systems should consult with their doctor before trying mushroom coffee. Safety always comes first when it comes to your well-being.
