(And If Yes, Then What Should You Know?)
Here’s a bit of health wisdom that might come as a surprise: You don’t need as much protein as you probably think you do. Really. The Mayo Clinic states most adults need somewhere between 46 and 56 grams of protein every day. And excess amounts of protein can be hard on your kidneys.
So, what’s the deal with protein supplements like shakes, powders, and bars? These products still offer a lot of benefit to those who need them, but it’s important to be judicious in choosing which one you’ll use and how you’ll use it.
Protein is a nutrient that your body needs to build and sustain all its elements—your blood, your bones, and, yes, your muscles. Protein is important if you’re trying to improve sports performance or build muscle mass, and if you’re an especially active individual, such as an athlete or a bodybuilder, you’re going to have needs that are greater than the 46–56 grams recommended for most people. The Academy of Nutrition and Dietetics and the American College of Sports Medicine encourage people who undertake rigorous physical activity to get about 1.2 to 2 grams of protein per kilogram of body weight every day. That means if you’re a 150-pound person (68 kilograms), you would need about 81 to 136 grams of protein. A 200-pound person (91 kilograms) would need 109 to 182 grams of protein.
That’s where protein supplements come in handy: These products can help you get more protein in your diet, although supplemental protein isn’t as good as the protein you’re getting from whole foods, which contain vitamins and minerals your body needs to flourish.
Note that your body can’t use more than 30 grams of protein at a time, so consuming a protein shake with 50 grams of protein won’t provide quite the benefit you expect it will. And after an intense workout, when your body has depleted all its glycogen stores, getting plenty of carbohydrates is just as important as getting plenty of protein. Aim for a 3:1 ratio of calories from carbohydrates to calories from protein—this might be a few crackers with nut butter or some Greek yogurt with fruit. This replenishment should come within an hour of finishing your workout.
When these protein-rich snacks aren’t sufficient or convenient, seek a protein supplement. Look for products that have less than 200 calories per serving, 20–30 grams of protein, and less than 5 grams of sugar.
It’s also helpful to pay attention to the different types of supplemental protein available on the market and choose the one that best fits your needs or goals:
Whey protein: This is the one that’s most prominent on the market, and it’s a great pick if you’re somebody who does dairy. Whey protein contains all the essential amino acids your body needs, and it’s easily digestible. Because whey is so efficiently broken down and used by your body, it’s great for people who are trying to build muscle.
Soy protein: Soy protein isn’t as efficiently used by the body as whey protein is, but for people who don’t do dairy, it’s a great pick because it also contains all essential amino acids. Soy foods have also been shown to help reduce high cholesterol and build strong bones.
Brown rice or pea proteins: These are other plant-based proteins, and they are hypoallergenic, so they are good for anyone who doesn’t tolerate soy well. Although brown rice protein and pea protein are incomplete protein sources individually, they provide all nine essential amino acids when consumed together. Look for a protein supplement that contains both if possible.
Hemp protein: Hemp protein is often made from milled hemp seed, so it is less processed than other protein powders on the market; however, it tends to be lower in protein per calorie compared with other supplements. It’s also full of fiber and omega-3 fatty acids for additional nutritional benefit.
Remember: If your goal is to lose weight, then you should be careful about not using a supplement with lots of added sugar. A protein supplement, whether high in sugar or low in sugar, will still be a source of additional calories, so consume with discretion. Mix your protein powder with low-fat or fat-free milk, almond milk, oat milk, or water instead of any high-sugar, high-fat beverages.
