Side effects. Green coffee seems to cause few side effects. The caffeine in green coffee -- just like the caffeine in brewed coffee -- can cause symptoms that include: 1  Headache. 2  Upset stomach. 3  Anxiety.

The refreshing drink is also packed with health benefits, says Nadine Taylor, registered dietitian and author of Green Tea: The Natural Secret to a Healthier Life.
