Best Single Ingredient: NAKED nutrition Naked Whey Unflavored Protein Powder

The supplement industry is like the Wild West at times. Supplement manufacturers do not have to obtain FDA approval before selling their products, which is why it's always a bonus when brands participate in third-party testing for quality assurance. Naked Whey goes through Informed Choice testing, a quality assurance program for sports nutrition products, suppliers to the sports nutrition industry, and supplement manufacturing facilities.

The unflavored variety of Naked Whey's powder is made from whey proteins that are produced with an acid-free and bleach-free process. The cows producing the whey are grass-fed throughout the year, and they are not given growth hormones.

Best Flavored: Source Organic Norcal Organic Peanut Butter Powder

Many flavored protein powders rely on artificial sweeteners or flavorings to enhance flavor. Norcal peanut protein leaves out the artificial stuff and relies on its single ingredient for its delicious flavor—peanuts. Norcal sources organic peanuts from Texas and relies on mechanical processing without the use of solvents, which keeps the dietary fiber from the peanuts intact.

This powder offers 11 grams of protein per serving, as well as significant amounts of magnesium and fiber. You can even re-hydrate this powder to substitute it for peanut butter in recipes when you'd like a little extra protein without the calories and fat.

Best Low-Carb: Realist Lifestyle Real Whey Protein Isolate

Realist Whey Protein Isolate powder is low in calories, carbohydrates, and fat, but high in protein–just one serving packs in 20 grams! Realist prides itself on using purposeful ingredients, without highlighting any truth-stretching benefits, and their powder lives up to this with only two ingredients: whey protein isolate and non-GMO sunflower lecithin.

While this powder isn't an option for anyone with wheat, dairy, soy, or tree nut allergies, it is a great option for people looking for a straight-forward powder to add to smoothies or shakes. The sunflower lecithin makes the powder easier to dissolve, so you'll barely even notice that it's there.

What to Look for in Protein Powder

Taste: Some protein powders can have a somewhat chalky consistency and an unappetizing aftertaste, while others taste almost like a milkshake you look forward to drinking. Many formulas come in a wide variety of flavors though, so if one isn’t your thing, another might be—you may just have to try a few before you find your favorite.

Purpose: While some protein powders are designed to help you lose weight, others are meant to bulk you up. Make sure you choose one that’s in line with your goals instead of one that thwarts them. Consider not only the amount of protein in any given powder but also the type of protein it contains. Protein powders are derived from a variety of sources, including whey, pumpkin seed, hemp, and more; each has varying nutritional benefits.

Ingredients: Beyond the type of protein in a certain powder, you’ll also want to consider its additional ingredients. Some formulas are fairly simple, while others include more nutrients, sugar, or fillers. If you like to keep things clean, there are a variety of protein powders that are free of artificial ingredients and sweeteners.
