For weight gain, you’ll want a protein powder that’s calorie-dense and easy to mix into shakes or meals. Whey protein is a popular choice because it’s absorbed quickly and packed with essential amino acids. Casein is another option if you prefer slower digestion, like before bed. Plant-based proteins work too, especially if you’re lactose intolerant or vegan. The key is picking one that fits your diet and helps you consistently add more protein and calories without feeling bloated or sluggish.
