Mushroom coffee, a beverage blending traditional coffee with powdered medicinal mushrooms, is gaining popularity, but its health claims are not extensively supported by scientific research. Experts advise consumers to consider potential drawbacks, including cost, quality control, and interactions with medications.
The price of mushroom coffee can be significantly higher than conventional coffee, with more exotic mushroom varieties contributing to higher costs, according to registered dietitian Toby Amidor. Another concern revolves around quality control, as mushrooms can absorb compounds from their environment. Sourcing and cultivation practices are crucial, and consumers should look for products tested for contaminants such as lead, arsenic, and mercury.
While generally considered safe, mushroom coffee may not be suitable for everyone. Individuals taking prescription medications are advised to consult their doctor before consumption. Certain mushrooms, like reishi, may interact with medications, including blood thinners. Additionally, chaga mushrooms are high in oxalates, which could pose a risk for those predisposed to kidney stones.
