How much protein do I need after a workout?
Around 20 to 30 grams of protein in the meal after a workout is plenty for most people. That is a chicken breast, three eggs, a cup of Greek yogurt, or a standard scoop of protein powder. More than that in one sitting adds little.
The famous 30-minute window is mostly marketing. Your muscles stay extra receptive to protein for a day or more after training. Your total protein across the whole day matters far more than the stopwatch.
Aim for roughly 1.2 to 1.6 grams per kilogram of body weight daily when you train, spread across meals, and a little more if you are over 60, since older muscle responds less to each meal. Food covers it; powder is convenience, not magic.

Not magic, just convenient
Useful when your plan calls for more protein than your meals reach, especially for older adults protecting muscle. Whey or a plant blend both work; unflavored mixes into anything.
