For serious muscle growth, look for a protein powder with at least 20-30 grams of protein per serving and minimal added sugars or fillers. Casein protein is another solid choice, especially before bed, since it digests slowly and provides a steady supply of amino acids overnight. Ultimately, the best protein powder depends on your dietary needs, budget, and how well your body tolerates it. Stick with reputable brands and check the label for quality ingredients.
