I can't do the math but I did ask the dietitian and she said the supplement counts as fluid. An RN at the hospital said 250 ml (1 cup) is counted as 200 ml. Being the exacting type, I have also checked with the RO and he said 6 cans of Nutren 1.5 is enough for John who is about 195 lbs in terms of both calories and hydration. If your husband's urine is a dark color, then he might be dehydrated, if it is normal-looking, then he isn't. That is what the RO said to use to check for dehydration. Hope this helps.

One more thing, practically all the nurses, doctors and the dietitian have told me that the fluid intake should be between 2000 to 3000 ml a day.
