i heard somewhere that your body only absorbs so much protein at one time.

Your body can absorb most of the protein you consume, but it's not really a matter of absorption, it's more to do with utilisation. When it comes to your body's daily building and repairing of muscles there's a limit to how much protein is beneficial in a single meal, although if you're very active or you're trying to build muscle you are likely to benefit from a higher protein intake than would otherwise be the case.
