Mushroom coffee is a beverage made of coffee blended with functional mushrooms like lion’s mane, chaga, reishi and turkey tail to increase focus and immunity, according to Tastewise Q2 Food Trend Report. Mushroom coffee can be found either ground form for traditional brewing methods or instant mixes and single serve pods; when purchasing this beverage it is important to keep in mind factors like caffeine content, preparation method and intended purpose when selecting their product.

Mushroom coffee tends to contain less caffeine than standard coffee; some brands even go so far as being decaffeinated or completely caffeine free, providing relief to individuals sensitive to its effects such as anxiety, heart palpitations and digestive upset. Furthermore, mushroom coffee may provide an easier transition for those trying to gradually reduce or discontinue caffeine consumption without abruptly going cold turkey.

However, even those with low tolerance to caffeine can still experience side effects from drinking too much mushroom coffee. Some varieties contain cordyceps which is known to stimulate the nervous system while some brands contain high concentrations of oxalates which have been known to cause kidney stones when consumed in excess.

To minimize potential side effects, it is essential that consumers select mushroom coffee that does not contain high levels of either caffeine or oxalates. While preliminary research supports its health benefits, more clinical studies must be completed in order to validate them.

Mushroom coffee products vary based on brand. Four Sigmatic’s Focus Blend features lion’s mane and chaga mushrooms which may help improve memory, concentration and immune function while providing immunity support. Each 12-ounce cup contains only 150 milligrams of caffeine compared with traditional coffee beverages.

Ryze’s instant mushroom coffee contains chaga, reishi, cordyceps and turkey tail mushrooms for optimal brewing results. Each serving provides 48 milligrams of caffeine.

Some brands of mushroom coffee combine various ingredients like turmeric and spirulina with them while others may include additional herbs or spices like cinnamon or stevia for an enhanced experience. Most mushroom coffees use hot water brewing systems to extract flavors and nutrients from dried mushrooms into beverages that satisfy both aesthetics and nutritional needs.

Researchers have proposed several benefits of mushroom coffee, including enhanced stress regulation, better sleep quality and stronger immune defenses. Mushrooms are known as adaptogens – meaning they help the body manage stress more effectively while balancing other chemicals in the brain – and some studies indicate that beta-glucans, ergothioneine and antioxidants found in mushroom coffee may promote this effect. Other researchers say the reduced cortisol levels caused by adaptogenic mushrooms in coffee may lead to more restful nights’ rest.
