The primary ingredient in Monster Energy drinks is glucose, a type of sugar. A 16 oz. Monster Energy drink contains 54 g of sugars. Glucose is obtained from the breaking down of sugar and starch in carbohydrates. This form of energy then is absorbed into the bloodstream by the small intestine and combines with insulin to enter the muscles and brain. According to the National Institutes of Health, glucose is a major source of energy for most cells of the body.


Taurine is an amino acid that supports neurological development and helps regulate water and mineral salt levels in the blood, notes A 16 oz. Monster Energy drink contains 2 g of taurine. Studies suggest that taurine may improve athletic performance and when combined with caffeine, may improve mental alertness; however, more research is needed to verify these findings, adds.
