How to choose a protein powder

Compare whey and plant-based protein powders by serving size, ingredients, and cost.

THE QUICK TAKE
  • Start with the protein you already get from food.
  • Choose a protein source that fits your preferences and dietary needs.
  • Compare protein per serving, ingredients, and the cost of the exact container.

Do you need protein powder?

Protein supports muscle maintenance and repair, including after training. Many people can meet their needs through food; a powder can be a convenient option when a meal or snack falls short. Your total daily intake and routine matter more than a single shake.

Whey or plant-based?

Whey protein

Whey comes from milk. Check the label for the type of whey, ingredients, and allergens. Whey isolate is a more concentrated form of whey protein.

Plant-based protein

Plant powders may use pea, soy, or other plant sources. Check the ingredient list and allergens; formulas and protein amounts vary.

Four things to check on the label

01 · Protein per serving

Check grams of protein and serving size together. A scoop size can differ between products.

02 · Ingredients

Review allergens, sweeteners, added sugar, and any ingredients you prefer to avoid.

03 · Cost per serving

Divide the current container price by its serving count. Confirm the flavor and size before comparing.

04 · Independent testing

Look for independent certification and confirm its current status with the certifier.

Shakes and bars are options too

Powder works well if you want to mix your own shake. Ready-to-drink shakes and bars may be easier on the go. Compare each by protein per bottle or bar, ingredients, and price per unit.
