how many milligrams of caffeine is in coffee?
Think again. One Journal of Analytical Toxicology report looked at nine different types of decaffeinated coffee and determined that all but one contained caffeine. The dose ranged from 8.6 mg to 13.9 mg. (A generic brewed cup of regular coffee typically contains between 95 and 200 mg, as a point of comparison. A 12-ounce can of Coke contains between 30 and 35 mg, according to the Mayo Clinic.).
