What’s in the bottle
Reishi (Ganoderma lucidum) fruiting body, grown in Poland and extracted in purified water and food-grade alcohol (under 22%) using ultrasonic-assisted dual extraction. Each 30 ml bottle contains 1,000 mg of extract (dry weight). No grain, fillers or flavourings. Vegan.
How to take it
Take 2 to 3 droppers a day, best in the evening. Each dropper holds about 0.6 ml (20 drops). Hold it under your tongue for 90 seconds or more, then swallow, or mix it into tea or water if you find the taste strong. Don’t take more than 2 ml (60 drops) a day.
| Drops | About |
|---|---|
| 20 drops (1 dropper) | 0.6 ml |
| 40 drops (2 droppers) | 1.2 ml |
| 60 drops (3 droppers) | 1.8 ml |
Reishi tastes bitter and can tingle a little under the tongue. That’s normal; it comes from the triterpenes in the mushroom.

Who you’ll talk to
I’m Brian Cusack. I started Dr. Mush Me because I couldn’t find a mushroom extract that told me exactly what was in the bottle. So we publish it: the species, the part of the mushroom, how it’s extracted and the lab report. If you have a question, Dean or I will answer it ourselves.
