The 7 Best Whey Protein Powders to Buy Now, According to Registered Dietitians

If protein powder is part of your day-to-day, cost per serving starts to matter. Depending on the container size and subscription, each serving of this powder costs as little as $1.09—roughly half the price of some other protein powders on this list. That makes it one of the most affordable ways to add 24 grams of high-quality protein to your day without sacrificing quality.

What I appreciate is that the lower price tag doesn’t require many of the compromises you’d expect with budget-friendly supplements. For starters, it’s third-party tested through Informed Choice. You also get more than 20 flavor options—including cookies & cream, fruity cereal, and s’mores—so you’re not limited to a handful of basic choices.

Each serving provides 24 grams of protein from a blend of whey protein isolate, whey protein concentrate, and hydrolyzed whey, with isolate serving as the primary protein source. It also remains relatively lean, with no more than 4 grams of carbohydrates and 2 grams of fat per serving.

This whey protein isolate proves you don’t have to sacrifice texture to get the benefits of an isolate. It offers the lower lactose content and high-quality protein that’s expected from an isolate, without the thin, watery texture common in many formulas.

The formula includes 1 gram of added L-leucine and 20 micrograms of vitamin D3, nutritional extras you don’t often find in many whey isolates. The added MCTs give the shake a more satisfying and creamier texture.

Every flavor is NSF Certified for Sport, giving athletes added confidence during training and competition.

I also appreciate that it’s available in travel packets in select flavors. Whether you’re traveling for a race, heading to training camp, or simply packing your gym bag before work, it’s much easier to grab a few packets than carry around an entire tub of protein powder.

The convenience doesn’t come at the expense of solid nutrition. Made with grass-fed whey protein isolate, it delivers 20 grams of protein for just 90 calories while remaining naturally low in carbohydrates and fat.

This one blends seamlessly into smoothies, oatmeal, Greek yogurt, baked goods, and more, adding protein while letting the original flavors have their moment.

Made with just two ingredients—grass-fed whey protein isolate and a small amount of sunflower lecithin for easier mixing—it delivers 28 grams of protein with 0 grams of carbohydrates and just 0.5 grams of fat per serving. That also means no added sweeteners, flavors, or unwanted fillers.

Along with Informed Choice certification, it’s also Informed Protein certified, meaning the protein content has been independently verified. Product purity and ingredient verification results are also available online.

After a long summer run or steamy workout, sometimes you want your protein to feel more like a thirst-quenching sports drink than a milkshake. That’s exactly what this clear whey formula delivers, packing 20 grams of high-quality protein into a light, refreshing drink for just 100 calories—a welcome change from traditional protein shakes.

It’s Informed Sport certified and Certified Gluten-Free, meaning the finished product—not just the ingredients—has been independently verified to meet strict gluten-free standards.

The two flavor options, orange mango and pineapple coconut, are bright, fruit-forward, and lightly sweetened. If you’ve ever wished protein powder tasted a little less like dessert, this formula is a refreshing reminder that it doesn’t have to.
