Protein utilization is dependant on many factors. The nutritional status of the individual consuming the protein, the manner in which the protein is presented to the stomach (whole as opposed to peptides), the protein???s amino acid composition, rate of digestion and absorption are just some of the factors that influence protein utilization.
Take a moment to think about the protein situation. 25 to 30 grams is about one ounce of protein 50g approx 2oz. Aside from water, the next most abundant element that your body is made of is protein. Also, your body is continually regenerating every cell, muscle, bone, skin, etc. So your body consists of newly regenerated cells about every 4 months. This would not be remotely possible if you could only utilize 30 ??? 50 grams of protein at a time.
Another thing that must be taken into consideration is the amount of muscle you have. The bigger you are the more protein you will need. That's common sense.

Pritein per 100g = 29.80g
