When choosing a protein powder for weight gain, focus on whey protein blends, mass gainers, or plant-based options with high protein content. Look for at least 20-30 grams of protein per serving and minimal artificial additives. Some powders even include digestive enzymes to help with absorption, which is useful if you’re consuming larger amounts. The key is finding one that fits your dietary needs and tastes good enough to stick with long-term.
