Mushroom supplements on the rise: reishi, lion's mane and more

Extracts of mushrooms such as reishi, lion's mane and cordyceps are appearing more and more frequently in web shops. They are advertised for everything, from resistance to concentration.
Laboratory research into the substances in these mushrooms is interesting, but good research in humans is still scarce. The leap from test tube to daily capsule is large.
Those who want to try it should choose a product with clear information about origin and dosage and keep expectations modest.
