Mushroom coffee: what is in the bag and what you pay for.
Mushroom coffee has gone from a niche product to a supermarket shelf in a few years. A typical bag costs around $40 for thirty servings, several times the price of good coffee. Here is what you are paying for, and four questions to ask before you do.
What is in it
Most mushroom coffees are instant or ground coffee blended with powdered mushroom extracts, often lion's mane, chaga, reishi and cordyceps, sometimes with cacao, cinnamon or adaptogens. Many contain less coffee than a regular cup, which is part of why people describe them as gentler: less coffee usually means less caffeine.
Four questions to ask
- How many milligrams of each mushroom per serving? A blend of four mushrooms in a 2–3 g scoop leaves room for only a few hundred milligrams of each, often less than the amounts used in studies. "Proprietary blend" labels that hide the amounts are a red flag.
- Fruiting body or mycelium on grain? Mycelium grown on grain can be mostly grain starch. Look for the beta-glucan percentage.
- How much caffeine? An 8-ounce cup of brewed coffee has roughly 80–100 mg. Mushroom coffees often state 40–100 mg. The FDA cites 400 mg a day as an amount not generally associated with negative effects for healthy adults.
- What does a serving cost? Divide the price by the number of servings, then compare it with a good coffee plus a mushroom extract bought separately. Separately is often cheaper, and you control the dose.
Our view
If you like the taste and want a lower-caffeine cup, mushroom coffee can be a pleasant habit. If you want mushrooms for their own sake, a labeled extract with a stated beta-glucan content gives you more for the money.
