Question: how many calories can the human body absorb in an hour?
Answer: By selecting a product with more than one source (e.g. sucrose and fructose), you are able to absorb more than when you consume a single source (e.g. glucose only). The general recommendation is to consume 30 – 60 grams of carbohydrate per hour or 120 – 240 calories per hour during endurance exercise.
