A medium sized chicken breast is around 50g of protein. If you can absorb a chicken breast (or a burger, or a steak) you can absorb the protein. If you're trying to gain strength of lean mass, you need 1.3 to 1.6g of protein per kg of lean body mass. Less than that and you're potentially leaving gainzzz on the table. More than that and you're just eating extra calories. It all gets absorbed but gets converted to glucose or fat rather than getting put towards muscle synthesis.
I do take whey protein myself, but I try to get all my protein from food. I use the protein every few days as needed to hit that 1.3-1.6g/kg target if I haven't had enough. And day-to-day its not as important, more like a weekly average. I use MyFitnessPal to track it along with calories. My goals are to get stronger without gaining weight.
