The All-in-One Stop for Your Protein Needs
Costco is a treasure trove for health-conscious shoppers looking to stock up on protein boosts at a great value. The wholesale retailer's bulk sizing and competitive pricing make it a go-to for gym-goers, dieters, and anyone aiming to increase their protein intake. From grab-and-go convenience items to versatile cooking staples, there is something for every taste and fitness goal. Navigating the protein aisle, however, can be overwhelming. This guide will break down the most popular and highly-regarded protein supplements and foods currently available at the warehouse, helping you make an informed decision for your nutrition plan.
Top-Tier Protein Shakes
For many, a convenient and effective protein boost comes in the form of a shake. Costco offers several top contenders in both ready-to-drink and powder formats.
Premier Protein Shakes
One of the most consistently popular protein boosts is the Premier Protein shake. Available in multi-packs, these shakes provide a hefty 30 grams of protein with only 1 gram of sugar, making them a staple for post-workout recovery or as a meal replacement. Flavors like chocolate, vanilla, and caramel are common finds.
Fairlife Protein Shakes
Fairlife is another customer favorite, known for its ultra-filtered milk base and smooth, less chalky texture. These shakes also deliver a solid 30 grams of protein and are celebrated for their delicious, creamy taste, making them a great option for those who are particular about flavor.
Kirkland Signature Whey Protein Powder
Costco's own Kirkland Signature brand provides a cost-effective whey protein powder. For those who prefer to mix their own shakes, this bulk bag offers great value with a solid nutritional profile. Customer reviews are generally positive for the creamy chocolate flavor, though some find it a bit sweet, and others have noted issues with mixability in older batches.
Other Protein Powder Options
Beyond the Kirkland brand, Costco often stocks other well-regarded powders like Optimum Nutrition Gold Standard Whey and Ascent Native Whey, appealing to customers looking for specific brands or formulations.
Highly-Rated Protein Bars
Protein bars are a go-to for on-the-go snacking or a quick energy fix. Costco carries several brands, including its own, which often spark lively debate among members.
Kirkland Signature Protein Bars
The Kirkland Signature protein bars are known for their macro-friendly profile and affordability, offering a significant amount of protein and fiber per bar. However, reviews are mixed, with some customers disliking the texture and artificial sweetener aftertaste in certain flavors, while others are loyal to specific variants like Chocolate Brownie.
RXBAR Variety Pack
For those who prefer whole, simple ingredients, the RXBAR variety pack is an excellent choice. Made with ingredients like egg whites, dates, and nuts, these bars provide 12g of protein and are gluten-free. Their flavor is well-regarded, with testers appreciating the natural taste and appealing texture.
Built Puffs
Built Puffs are a newer, popular item at Costco, offering a marshmallow-like texture. They come in a variety pack with flavors like Brownie Batter and Coconut, providing a tasty, lighter option for a protein boost.
Savory and Whole Food Protein Snacks
Protein boosts don't always have to come in a bar or shake. Costco's refrigerated and pantry sections are full of high-protein, convenient food items that can supplement any diet.
