Last updated: June 2026
This guide is regularly reviewed with new insights on medicinal mushrooms.

Medicinal mushrooms have become considerably more popular in recent years, but they are anything but new: for centuries they have been used in traditional medicine to support the immune system and overall well-being. In this guide we explore the 5 best-known ones, how they work and what each is known for. See this blog as a starting point: for each species we have a separate, deeper guide you can move on to from here.

What Are Medicinal Mushrooms?

Unlike regular edible mushrooms, medicinal mushrooms have long been used for their special properties. They contain bioactive compounds, such as beta-glucans and other polysaccharides, plus antioxidants. The best-known are reishi, chaga, cordyceps, turkey tail and lion's mane, each with its own profile.

How Do Medicinal Mushrooms Support the Immune System?

It may be hard to believe, but humans and mushrooms share a common ancestor; genetically, mushrooms resemble us more than plants. Fungi have developed powerful ways to withstand pathogens, and certain compounds from them are associated in research with the immune system. The beta-glucans and polysaccharides in medicinal mushrooms are studied for their ability to 'modulate' the immune response, helping to bring it into balance. They also provide antioxidants, which help protect the body against oxidative stress. It is important to see this as support, not as treatment.

The 5 Best-Known Medicinal Mushrooms

Medicinal mushrooms to support the immune system

Each species has its own character and is traditionally valued for something different. A brief introduction, with a link to the in-depth guide for each:

  • Reishi — the 'mushroom of immortality', traditionally used for immune support, relaxation and sleep. Read meet reishi.
  • Chaga — the 'king of mushrooms', known for its high antioxidant content.
  • Cordyceps — long used for energy and endurance. Read the cordyceps guide.
  • Turkey tail — rich in polysaccharides (PSP and PSK). Read about turkey tail.
  • Lion's mane — a natural nootropic, loved for focus and concentration. Read the benefits of lion's mane.

Using and Combining Medicinal Mushrooms

Medicinal mushrooms come as liquid extract, powder and capsules. If you are just starting, choose one species so you get to know its effect. Many people later combine them, as the species complement each other nicely. An easy way is to add them to a drink or smoothie; you will find recipes in our smoothie recipes.

Important: Medicinal mushrooms are food supplements and not a substitute for medical treatment. Do you take medication, are you pregnant or do you have health complaints? Then consult a doctor or healthcare professional first.
