The greatest potential risks and side effects of ingesting Nestle Nutrition's Boost energy drink are increased body weight, a higher risk of developing type 2 diabetes, and risk of heart disease. However, these side effects usually only occur after extended consumption.
Like most energy drinks, Boost High Protein Energy Drink relies on the effects of caffeine and sugar to produce the an immediate lift in perceived energy in the consumer. The average 250-milliliter can of Boost contains 80 milligrams of caffeine and 18 to 27.25 grams of sugar; increased intake of sugar in particular is directly linked to increased weight gain due to empty calories. The average 8-ounce can of Boost contains 240 calories.
Those with a history of diabetes or heart disease should discuss with their physicians their decision to start taking Boost; while Boost is in no way directly linked to either of these conditions, its sugar and cholesterol levels put those with personal or family histories at greater risk of becoming symptomatic.
Those with lactose intolerance should be aware that the protein in Boost consists of milk protein. However, any individual with this condition should check the ingredients on any product before consumption, as the side effects of neglecting to do so may include bloating, diarrhea, excess gas, nausea and stomach cramping.
