Tag: Quest shakes

Over 30% of US consumers incorporate protein drinks into their weekly diet, highlighting the need for quality, on-the-go nutrition. When assessing what protein shakes compare to Fairlife, many are searching for the same winning formula: high-quality protein, a smooth texture, and minimal sugar, all in a convenient package.

According to official product information, Quest ready-to-drink shakes contain a powerful blend of milk protein concentrate and milk protein isolate, while their protein powders utilize a mix of whey protein isolate and micellar casein. This variation allows Quest to tailor protein absorption speeds and product form to different consumer needs and preferences.

As of late 2025, Quest Nutrition 45g Protein Milkshakes have been available on Costco's website, confirming that the popular protein brand has made its way to the wholesale giant's online store. However, this availability can fluctuate, and the stock often varies between the online and physical warehouse locations. This means while you can find Quest protein products at Costco, it's not a guarantee that the specific shakes will be in stock at all times or in every store.
