Abstract	Objectives: Most cases of caffeine intoxication result from the excessiveintake of over-the-counter drugs and energy drinks. However, few cases of caffeineintoxication due to the excessive consumption of bottled coffee products have beenreported. Herein, we present a case report of caffeine intoxication.Patient: A 39-year-old man experienced numbness and weakness in theextremities for three nights over five days.Results: Blood tests revealed hypophosphatemia and low 25-OH vitamin Dconcentration. The symptoms disappeared the next day without any additional treatment. Alifestyle interview revealed that he regularly consumed bottled coffee like it was waterand had approximately 1 L of it from evening to night. He was diagnosed with weakness inthe extremities due to hypophosphatemia caused by caffeine intoxication. Uponinvestigating some bottled coffee products, we found that only a few of them had labelsdisclosing caffeine content and warnings of the risks of excessive caffeine intake.Conclusion: We encountered a case of caffeine intoxication via coffee.Although rare in the past, caffeine intoxication might increase owing to the widespreaduse of bottled coffee products. The caffeine content of coffee products should beindicated on labels to warn consumers.
