Mushroom coffee has taken the nation by storm. A blend of regular coffee with dehydrated ground mushrooms (or extracts), mushroom coffee promises various health benefits such as enhanced focus and immunity. According to its marketers, mushroom coffee works like a “natural nootropic”, providing energy boost without caffeine side effects like jitters or an increase in heart rate.

mushroom coffee products have become more commonplace, from instant varieties, ground versions and ready-to-brew pods, available at specialty stores or ordered online. Ingredients can differ between brands; generally speaking, however, the taste remains similar with just darker hues from added mushrooms. They are said to provide health or medicinal benefits such as brain enhancement, stress relief, immune support and even improved digestive tract functioning.

Mushrooms have long been recognized for their anti-inflammatory and antioxidant benefits, and some research suggests a reduced risk of chronic diseases and conditions. Although there has been limited scientific support to back these claims up, those who have tried mushroom coffee report feeling less anxiety, better focus, and sustained energy throughout their day than with traditional coffee brew. Furthermore, mushroom products contain half or even less caffeine compared to their traditional counterparts.

However, some have raised concerns that these products may be a fraud and should not be seen as a replacement for a healthy diet. Many mushroom coffee brands lack transparency regarding their ingredients or sourcing processes, with some products even found to contain potentially toxic levels of compounds – not to mention certain mushrooms being toxic if consumed excessively or by people with certain medical conditions.

Sheri Berger, a registered dietician specializing in plant-forward nutrition, does not believe there is sufficient evidence supporting mushroom coffee as a nutritional solution. “It is best to obtain all your necessary vitamins from healthy eating habits.”

She notes that mushroom coffee may be an effective solution for those seeking to limit their caffeine intake and improve sleep quality, with adaptogenic herbs added for additional benefit. As with anything new, it’s always wise to consult your physician prior to trying something different. As mushrooms can interact with medications or health conditions, starting off slowly can help avoid allergic reactions in some. Starting small and slowly building up to larger serving sizes will minimize any potential for an adverse reaction and ensure you receive an appropriate dosage of mushroom coffee products. Pregnant or breastfeeding women should avoid them.
