In response to the Healthbeat article in the Sept. 26 issue of the Doings newspapers, the article by Dr. Gary Frumkin on energy drinks has a major error. The error is in saying that “vitamin B is an energy source” and further that “it is converted into glucose.”
The B vitamins are involved in energy metabolism as coenzymes that function as catalysts. They are neither a source of energy nor converted into glucose.
