Q: What is the best protein to take before bed?

A: Casein is the best protein for taking before bed. It prevents your muscles from feeding on themselves when you run out of fuel in your system overnight, and helps you avoid waking up hungry at 4 a.m. Casein protein also helps you out when you’re dieting because it keeps you feeling full with relatively few calories.

Q: Is whey protein good for building muscle?

A: Whey receives much of the love, and deservedly so, as it makes a super-fast-digesting protein powder that’s great for building muscle. But casein, which makes up a full 80 percent of the protein in milk, is also a heavy hitter.

Q: Is casein protein good to take before bedtime?
