Making the Best Choice for a Costco Protein Shake
Navigating the supplement aisle at Costco can be overwhelming, with multiple brands competing for attention. While personal preference plays a role, a few key factors should guide your decision to ensure you get the best value and nutritional benefit. The primary considerations are taste, protein content, sugar levels, ingredients, and cost.
Why Fairlife Nutrition Plan is the Top Contender
Many editors and consumers agree that Fairlife Nutrition Plan is the top protein shake at Costco. Its core strengths lie in its unique formulation and excellent taste profile, setting it apart from other bulk options.
The Fairlife advantage comes from its use of ultra-filtered milk. This proprietary process concentrates the milk's natural protein and calcium while removing most of the lactose, resulting in a product that is both high in protein and lactose-free. This provides a creamy, rich taste reminiscent of real milk, a significant upgrade over the sometimes artificial-tasting or chalky texture of other brands.
Key features of Fairlife Nutrition Plan shakes:
- High-Quality Protein: Each 11.5 fl oz bottle contains 30 grams of high-quality protein, an ideal amount for a snack or post-workout recovery.
- Low Sugar: With only 2 grams of sugar per serving, it's an excellent option for those monitoring their sugar intake or following a low-carb diet.
- Low Calories: At just 150 calories per serving, it provides substantial protein without excessive caloric cost.
- Delicious Taste and Texture: The use of ultra-filtered milk gives it a smooth, creamy consistency that many find far superior to other shakes.
- Added Nutrients: It contains naturally occurring vitamins and minerals, including calcium, without added protein powders.
Comparison of Top Costco Protein Shakes
To fully understand why Fairlife is often considered the best, it's helpful to compare it directly with its main rivals at Costco, including Premier Protein and the house brand, Kirkland Signature. For those needing maximum protein, the Fairlife Core Power Elite is also a strong alternative.
| Feature | Fairlife Nutrition Plan | Premier Protein | Kirkland Signature Whey Protein Powder | Fairlife Core Power Elite |

| Sugar (per serving) | 2g | 1g | No added sugar | 2g |

| Lactose-Free? | Yes | Yes | N/A (powder, varies with liquid) | Yes |
Other Options to Consider: A Closer Look at the Competition
While Fairlife is a fan favorite, other Costco-carried shakes have their merits, depending on your priorities.
Premier Protein
Premier Protein is a popular and widely available choice, with 30 grams of protein per serving and a low 1 gram of sugar. It also comes in many flavors, offering more variety than Fairlife's core options. However, many people find its taste and texture inferior, describing it as thin or artificial compared to the creamy Fairlife. Premier Protein also uses artificial sweeteners like sucralose, which some prefer to avoid.
Kirkland Signature Whey Protein Powder
For those who prefer powders to ready-to-drink shakes, Costco's house brand offers a whey protein powder. It provides excellent value for money and a solid protein count, typically 25 grams per scoop. The flavor is generally considered good, but some find it too sweet, a common issue with protein powders. Mixing can also be inconsistent, and it contains artificial sweeteners. This option is best for those who want to save money and are willing to mix their shakes themselves.

Nurri 30g Protein Shake
Nurri is a newer option at Costco that is becoming more popular. It offers 30 grams of protein, a lower sugar and carb count than some alternatives, and comes in recyclable cans. Some tasters find the chocolate flavor to be less intense than Fairlife's, but it's a solid, budget-friendly choice that appeals to those concerned about ingredient lists and packaging.
Conclusion
Ultimately, while the optimal protein shake depends on individual needs, the Fairlife Nutrition Plan shake is the most compelling choice for the average Costco shopper. Its combination of 30g of high-quality, lactose-free protein, ultra-creamy texture, delicious taste, and low sugar content makes it a standout product. While Premier Protein offers more flavor variety and the Kirkland Signature powder is cheaper, Fairlife's overall balance of flavor and nutrition is unmatched for a ready-to-drink product. If you're looking for one shake that checks all the boxes, Fairlife is the clear winner. The Core Power Elite is a great alternative for those who need a higher protein content after an intense workout.
