According to customer reviews on Amazon.com, Organo Gold Coffee is rated at 4.5 stars out of five. However, the reviews are heavily split, and several customers only give the product a single star, as of 2015.
Organo coffee contains a botanical extract called Ganoderma as well as regular coffee, and the positive reviews for the product praise its rich flavor and low caffeine content. Users also note improved concentration levels and reduced caffeine withdrawal symptoms. The negative reviews focus on the potential harmful effects of the Ganoderma, a fungal ingredient that can cause reactions in a small number of cases, and on the salespeople associated with the product.
