Functional mushrooms: Lion's Mane, Cordyceps, Reishi, Chaga

Functional mushrooms show up in coffee, pre-workouts and focus powders. They have a long history in traditional use; the modern research is still early.

The four you'll see most

  • Lion's Mane (Hericium erinaceus): the shaggy white mushroom most often marketed for focus.
  • Cordyceps (Cordyceps militaris or sinensis): usually marketed for energy and endurance.
  • Reishi (Ganoderma lucidum): a traditional mushroom often marketed for calm and overall wellness.
  • Chaga (Inonotus obliquus): a fungus that grows on birch trees, common in mushroom coffees.

What the research says, honestly

Most studies on these mushrooms are in the lab or in animals. Human studies exist but tend to be small and short. They're a reasonable thing to try if you're curious, but they aren't a replacement for sleep, food and training, and you should be wary of anyone promising dramatic results.

Why they're paired with caffeine

Mushroom pre-workouts and coffees usually combine the mushrooms with caffeine. The caffeine is the part you'll feel right away, so check the total caffeine on the label. See caffeine in supplements.

Before you start

If you're pregnant or nursing, take medication (especially blood thinners or diabetes medication), or have a medical condition, ask your doctor first. Stop if you notice stomach upset or other side effects.
