Start with the protein source and your dietary needs: whey is made from milk, while plant-based blends often combine sources such as pea and rice. Check the protein per serving, serving size, added sugar, and allergen information rather than relying on the front label alone. A scoop commonly provides about 20 to 30 grams of protein, but powders vary in calories, flavor, and texture. If you use protein powder often, compare the cost per serving and make sure you like the flavor enough to finish the tub.

Optimum Nutrition Gold Standard 100% Whey is our top pick for its broad availability, 24 grams of protein per serving, and mix of whey sources. For a lower-cost option, Nutricost Whey Protein Concentrate offers 25 grams per serving in a large tub, though it has fewer specialty dietary features.

How to choose

Choose your protein source

Whey and milk-based powders are not suitable for people with a milk allergy. If you avoid animal products, look for a clearly labeled vegan blend, often made with pea, rice, or other plant proteins.

Compare protein per scoop

Many powders provide about 20 to 30 grams of protein per serving. Check the serving size too: a larger scoop can make a product look more protein-rich while adding extra calories.

Check sugars and calories

Compare the nutrition label for your chosen flavor, since sweeteners and calories can vary within the same product line. If you track carbohydrates or added sugar, check those numbers directly rather than relying on terms like 'lean.'

Consider cost per serving

Divide the tub price by the number of servings to compare value fairly. A large container may cost less per scoop, but only buy it if you are comfortable with the flavor and serving size.

Frequently asked questions

How much protein should a protein powder serving have?

Many powders provide about 20 to 30 grams per serving, but the right amount depends on your overall diet and needs. Check the serving size and nutrition label, and count protein from meals as well as shakes.

Is whey or plant protein better?

Neither is automatically better for everyone. Whey is a milk-based option, while plant powders suit people avoiding animal products; compare protein per serving, ingredients, and how well you tolerate each.

Can I use protein powder every day?

Many people use a powder as a convenient way to add protein, but it does not need to replace a varied diet. Follow the serving directions and check with a health professional if you have a medical condition or dietary restrictions.

Does protein powder help build muscle?

Protein powder can help you meet your daily protein needs, but it does not build muscle on its own. Strength training, enough food, and recovery also matter.
