Does your body absorb meal replacement drinks like food?

Question

What I mean is, if you drink a shake with 60 grams of carbs and 40 grams of protein, does your body actually get all of this? I ask because I know that when you take certain vitamins, they say that your body doesn't absorb most of the vitamin sometimes (like b12). EDUCATED ANSWERS ONLY PLEASE.

Answer 1

the digestibility of powdered supplemental protein powders are superior than whole food proteins. after digestion 100% of the amino acids are available with supplemental protein powders, whole food proteins range from 100% with whole milk and whole eggs down to 50% with nuts, seeds and some grains.
