Why protein powder?
A 2018 study from the British Journal of Medicine shows that dietary protein supplementation (up to a maximum 0.73 grams of protein per pound of body weight per day) significantly increased strength and muscle size in adults, especially those who participate in resistance training.
While most people get enough protein from food, Hillary Ake, a registered dietician who works with professional and college athletes says, "when you exercise the working muscles go into protein breakdown mode, and sometimes even muscle breakdown and muscle damage, depending on the type of exercise. Replenishing protein after a workout can push the body back into muscle protein building mode, to help repair muscle damage and build muscle."
When it comes to protein powder intake, the more active you are, the more protein you need. The average athlete should take between "1.2 - 2.0 grams of protein per kilogram body weight (0.5 - 0.9 grams per pound), while a sedentary adult should take 0.8 grams of protein per kilogram (0.36 grams per pound)" Alex Larson, a registered dietician who works with endurance athletes, said.
While protein powders are generally considered safe, Larson suggests anyone with kidney-related issues consult a doctor before using any protein powders.
Types of protein powder and what to look for when choosing
"First thing to look for in a protein powder is third-party testing," Larson said, "which assures that what's listed on the package is actually what's in the product."
Next, it's important to know what you're looking for in a protein powder. (The FDA doesn't currently regulate protein powders, which makes getting the right information that much more important.)
There are two kinds of protein powders. Whey protein powders such as Optimum Nutrition's Gold Standard are derived from milk, while vegan options such as Orgain are derived from vegetarian sources such as peas, soy or hemp. Whey proteins are the most common, but vegan options are effective in supplementing protein too (though usually require higher doses).
When shopping for whey proteins, know there are two types: whey protein isolate and whey protein concentrate. Experts generally recommend a whey protein isolate powder, which is strained in a way that yields a higher percentage of protein and a lower percentage of lactose than a protein concentrate.
Athletes and exercise enthusiasts who are looking to replenish their body's supply after long endurance work may opt for a protein powder with added carbohydrate. Ake suggests those looking for a protein powder with an added carbohydrate aim for a "4:1 or 3:1 carb to protein ratio depending on your activity," adding that endurance athletes will require more carbohydrates to replenish their bodies after pro-level workouts.
