Oh sports nutrition there is actually a certain amount an elite athlete (human body) can absorb. It is generally not greater than 1g carb per min. Now this is during some intense exercise when cyclists ingest and water dextrose. There is some new research providing evidence that fructose in combination of dextrose improves rate of absorption above 1g per min. Fructose can be absorbed in a different pathway than dextrose. Again these are top cyclists NOT weight lifting HAHAH
