Whey protein powder is a high-quality protein source and contains all essential amino acids, as well as some branched-chain amino acids (BCAAs), which are building blocks for muscle growth. The dairy-derived powder is popular among athletes and those looking to boost their protein intake, and for a good reason. Research published in 2017 shows that supplementation with whey protein is associated with enhanced protein metabolism and may promote enhanced performance and recovery among resistance-trained individuals.

Whether you're looking to add a protein source to your smoothie or up your post-workout nutrition, whey protein powder is an excellent addition to your diet. With many options on the market, it can be challenging to find a product that is made from high-quality ingredients and tastes great.

Here, the best whey protein powders:

Best Overall: Tera's Whey Grass Fed Whey Protein Powder Bourbon Vanilla

Tera's Whey Grass Fed Simply Pure Whey Protein

If you're looking for a great-tasting, nutrition-packed whey protein powder, Tera's Whey Simply Pure is a great option. The certified gluten-free product is sweetened with stevia and provides 21 grams of protein per serving. Each serving also provides 5.29 grams of BCAAs along with 3 grams of sugar and 4 grams of carbohydrates.

The USDA Organic, rBGH-free, and rBST-free whey protein is sourced from grass-fed cows raised on small farms in Wisconsin. The bourbon vanilla flavor is sweet and mixes well with water or your favorite beverage. Note that the product mixes best using a shaker bottle or blender.

Best Budget: NAKED nutrition Naked Whey 100% Grass Fed Unflavored Whey Protein Powder

Containing only one ingredient (100% grass-fed pure whey protein), Naked Whey is a high-quality whey protein product with a reasonable price tag. The whey is sourced from small dairy farms in California and is cold-processed to ensure no contamination from chemical detergents, synthetic additives, or heavy metals. This pure product is also free of flavors, sweeteners, and colors.

The GMO-free, soy-free, and gluten-free product provides 25 grams of protein, 2 grams of sugar, and 5.9 grams of BCAAs per serving. Naked Whey is also a great choice for athletes, as it has the Informed-Choice Certification, assuring that it does not contain banned substances.

Best Unsweetened: NOW Foods NOW Sports Whey Protein Isolate

With 25 grams of protein per serving and no artificial sweeteners, NOW Sports Whey Protein Isolate is an excellent, high-value choice for a protein powder. The whey protein provides essential amino acids for muscle building while also supporting post-workout recovery.

NOW Sports' product is a whey protein isolate, as opposed to a concentrate. Isolate is typically more processed than concentrate, making it lower in carbohydrates and lactose. Due to the extra processing, isolate is typically more expensive; however, NOW Sport offers a bulk option to create more bang for your buck.

The whey protein isolate powder mixes very easily and is unflavored, so it can mix easily into any shake or smoothie with minimal taste.

Best-Tasting: Primal Kitchen Primal Fuel Vanilla Coconut Whey Protein Powder

Primal Kitchen's Primal Fuel comes in two delicious flavors, including vanilla coconut and chocolate. Monk fruit extract is used for sweetening, so the product is low in sugar, with only 1 gram per serving. Each scoop provides 10 grams of protein, 4 grams of carbohydrates, and approximately 2.2 grams of BCAAs.

The soy-free, gluten-free, keto, and paleo-friendly product provides 4 grams of medium-chain triglycerides (MCTs) from coconut milk fat. Research suggests that consumption of MCTs is associated with weight loss and greater usage of fat as fuel. Note that the product is not technically paleo, as whey protein is made from dairy.

Primal Fuel also contains prebiotics, or the food for gut-healthy probiotics, from inulin, a prebiotic fiber thought to improve digestive health.

Best Sugar-Free: Biochem 100% Whey Isolate Protein

Biochem is known for creating high-quality whey protein from grass-fed cows. The soy-free, non-GMO product contains no artificial ingredients and contains all essential amino acids. Each serving contains 20 grams of protein with no fat or sugar.

Biochem uses a specific cold process without chemicals to create a pure whey protein isolate. Their micro-filtration method removes fat, cholesterol, and lactose to create a highly pure whey protein powder. The low-FODMAP product is also great for those with food allergies and sensitivities as it is Certified Gluten-Free, soy-free, and 99% free of lactose.

What to Look for in a Whey Protein Powder Supplement


One of the most important factors to consider when choosing a protein powder is your goals. Some powders are low in calories and designed to help you lose weight, while others aim to build muscle mass by providing a higher amount of protein and calories per serving. Make sure the one you choose is in line with your goals, or you could end up sabotaging your efforts.


Protein powders come in a wide range of flavors, from basic chocolate and vanilla to mocha and even birthday cake. Depending on the ingredients, some may taste more chalky or artificial than others. Note that we generally recommend unflavored or naturally-flavored products, as we do not recommend dietary supplements with artificial flavors. If you want to boost the flavor of your protein powder, consider mixing the protein powder into a smoothie packed with tasty ingredients like frozen banana, cocoa powder, cinnamon, and almond milk.

Dietary restrictions: 

When choosing a protein powder, you want to consider any dietary restrictions or food sensitivities you may have. There are protein powders to accommodate most diets, including dairy-free, gluten-free, and vegan options, as well as those that have no artificial sweeteners, flavors, or colors. If you have any questions about adding a protein powder to your diet, talk with your doctor or a registered dietitian. They can help you determine if a protein supplement is right for you. 


Whey is a product derived from dairy, so it is important to consider quality when purchasing a whey protein powder. When possible, choose an organic whey protein powder to ensure you're getting high-quality protein without any antibiotics or growth hormones.
