When it comes to unlocking muscle growth and repair, protein is the master macronutrient. It’s the skeleton key to building serious size and retaining quality mass on a cut. You can train like a person possessed, tinker obsessively with your fats and carbs, and rest like it’s your job, but the door to significant muscle growth simply won’t open—or at least won’t swing wide—without enough protein in your diet.
How much is enough? While there are a few schools of thought on optimal goal-based protein intake, an easy target is to consume 1 gram of protein per pound of body weight every day. Weigh 180 pounds? Get 180 grams of protein! Eat, grow, repeat. Easy, right?
The numbers may be simple, but the tough part is getting all that protein from your diet—especially without scaling a mountain of Tupperware and chicken breast every day. Whole foods are swole foods, as they say, and while it is important to eat as much quality whole-food protein as you can, protein supplements are an extremely useful addition to your nutrition plan.
The best protein supplements are convenient, delicious, made from high-quality protein sources, and can help you stride through the door to new growth. Here are five of our favorites.
1. Bodybuilding.com Signature Protein Crunch Bars

At just 230 calories a pop, these bars are a great way to conquer your cravings while you crush your goals.
2. JYM Supplement Science Pro JYM Protein Powder

Available in nine refreshing fruit flavors ranging from Alpine Punch to Passion Fruit, this is a clear protein drink that’s perfect as a post-workout treat.
