Navigating Costco's Protein Drink Aisle
Costco is renowned for its bulk-size products and competitive pricing, and its protein drink selection is no exception. Shoppers can find a variety of ready-to-drink (RTD) options from major brands like Fairlife and Premier Protein, as well as Costco's own Kirkland Signature and Nurri brands. Choosing the "best" option, however, depends heavily on individual factors such as dietary goals, taste preference, and budget. For some, the most important metric is the protein-to-sugar ratio, while others prioritize ingredients or overall flavor profile. This guide will break down the most popular choices to help you make an informed decision.
Fairlife Nutrition Plan: The Premium Favorite
Fairlife Nutrition Plan shakes are frequently highlighted for their clean taste and impressive macronutrient profile.
Pros:
- High Protein, Low Sugar: Each 11.5 oz (or 340 mL) shake contains 30 grams of protein and only 2 grams of sugar.
- Ultra-Filtered Milk: The protein comes from ultra-filtered milk, which removes most of the lactose, making it easier to digest for those with sensitivity.
- Smooth Texture: Reviewers consistently praise the smooth, creamy texture that closely resembles a milkshake, avoiding the chalkiness of many other brands.
Cons:
- Higher Cost: Fairlife is often one of the more expensive options at Costco, though buying in bulk is still a significant saving compared to other retailers.
- Limited Flavors at Costco: While Fairlife has more flavors, Costco warehouses typically stock only chocolate and sometimes vanilla.
Premier Protein: The Classic Workhorse
Premier Protein is a long-standing favorite, known for its wide flavor selection and balanced nutrition.
Pros:
- High Protein: Offers 30 grams of protein per shake.
- Excellent Value: Often sold in large 18-packs, Premier Protein shakes are very cost-effective, particularly when combined with Costco's instant savings.
- Variety of Flavors: Premier Protein offers a wider range of flavors than Fairlife, including popular choices like Caramel and Café Latte, though not all may be available at every Costco.
Cons:
- Artificial Ingredients: These shakes are formulated with artificial sweeteners like sucralose and acesulfame potassium, which some health-conscious consumers prefer to avoid.
- Ingredient Quality: The protein blend includes milk protein concentrate and casein, which may not appeal to those seeking a cleaner ingredient list.
Nurri: The Budget-Friendly Contender
Nurri is Costco's private-label competitor to Fairlife, offering a similar profile for a lower price.
Pros:
- Great Price Point: Nurri shakes are considerably cheaper than Fairlife, making them a budget-conscious alternative.
- Recyclable Packaging: Packaged in recyclable aluminum cans, an eco-friendly benefit over plastic bottles.
- High Protein: Like its competitors, Nurri offers 30 grams of protein per serving.
Cons:
- Potentially Thinner Consistency: Some reviewers note that Nurri can be slightly more watery in consistency compared to Fairlife's creamy texture.
- Fewer Flavors: The flavor selection is often limited, with chocolate being the most common.

For most people prioritizing taste and a clean, ultra-filtered dairy source, Fairlife Nutrition Plan is the superior ready-to-drink protein shake at Costco. It delivers a rich, creamy flavor and an excellent macronutrient ratio of high protein and low sugar. However, excellent alternatives exist for different priorities. Premier Protein offers a more budget-friendly and wider flavor variety, while Nurri provides a low-cost, eco-friendlier version of Fairlife.
