Does Costco Sell Quest Shakes? Finding Your Protein Fix

5 min read

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.

Quick Summary

Yes, Costco carries Quest shakes, primarily online, but stock and flavor options can vary, prompting shoppers to check the Costco website or look at reliable alternatives like Fairlife and Premier Protein. Other retailers like Amazon, iHerb, and Whole Foods are more consistent sources for a wider variety of Quest products.

Key Points

  • Availability at Costco is Inconsistent: While Costco has sold Quest shakes online and sometimes in-warehouse, their stock is not reliable due to rotating inventory.

  • Check Costco.com First: The website is the most accurate source for current availability, often indicating if an item is backordered or online-only.

  • Explore Alternatives at Costco: Retailer often carries consistent stock of popular competing protein shakes like Fairlife and Premier Protein.

  • For a Guaranteed Supply, Shop Elsewhere: Consistent Quest availability is found at online stores like Amazon or specialty retailers like iHerb and Whole Foods.

  • Compare Nutritional Information: When considering alternatives, compare the protein, sugar, and carb content to ensure it aligns with your dietary needs.

  • Use Costco Notifications: If you are determined to buy from Costco, sign up for email notifications on their website to be alerted when Quest shakes are back in stock.

For fitness enthusiasts and health-conscious shoppers, Costco often provides a convenient way to purchase health and nutrition products in bulk at a discounted rate. Given its reputation for carrying popular, high-protein brands, many people ask: Does Costco sell Quest shakes? The answer is yes, but with some key considerations regarding product availability and stock fluctuation. Costco has been known to carry Quest Nutrition products, specifically the ready-to-drink protein milkshakes, through its online platform, Costco.com. What's more, there have been reports of these products appearing in physical warehouses as well, although this is less consistent and may depend on the specific location and regional stock.

Current Status of Quest Shakes at Costco

As discovered through a recent Instagram reel and several product listings, Costco has stocked the Quest Nutrition 45g Protein Milkshake, typically in a 12-pack of 14 fl oz bottles. These ready-to-drink shakes are a favorite for their high protein content (45g), low sugar (2g), and gluten-free formula. However, product listings on Costco's website frequently indicate that the item may be out of stock, backordered, or only available for delivery, suggesting inconsistent supply. This variability is a hallmark of Costco's constantly rotating inventory, where even popular items can disappear and reappear without warning.

Where to check for Quest shakes at Costco:

  • Costco.com: This is the most reliable place to check for current stock, including both online delivery and warehouse availability information. Checking the product page will show if the item is backordered or available for shipping. For example, a recent search shows the Quest Nutrition 45g Vanilla Protein Milkshake available for delivery.
  • Local Warehouse: In-store stock is less predictable. While some reports from shoppers suggest seeing Quest shakes in warehouses, the best practice is to call your local store directly or check the Costco app to see if they are in stock near you.
  • Instacart/Same-Day Delivery: Services that partner with Costco, such as Instacart, sometimes list Quest products, but their inventory reflects local warehouse stock, so a search might yield no results even if the item is on Costco's main site.

Quest Alternatives and Where to Find Them

If you can't find Quest shakes at Costco, don't worry. The retailer offers a strong selection of high-protein alternatives. You can also explore a variety of other retailers that consistently carry Quest products.

Other Protein Shake Options at Costco

Costco regularly stocks popular protein shake brands that rival Quest in nutritional value and taste. These are often sold in large, budget-friendly packs.

  • Fairlife Nutrition Plan Shakes: Known for their ultra-filtered milk, Fairlife shakes offer around 30g of protein and 2g of sugar per serving, similar to Quest's low-carb profile.
  • Premier Protein Shakes: A very common sight at Costco, these shakes typically provide 30g of protein and come in various flavors, often at a competitive price.
  • Kirkland Signature Protein Bars: While not a shake, Costco's house brand protein bars are a popular and affordable option for those looking for a high-protein snack on the go.

Alternative Retailers for Quest Products

For more consistent and a wider variety of Quest protein products, consider looking beyond Costco. These retailers are known for their reliable stock of Quest shakes, bars, and chips.

  • Amazon: Offers a wide selection of Quest shakes, with options for different flavors, sizes, and subscription services for regular delivery.
  • iHerb: An online retailer specializing in health products, iHerb often carries Quest shakes and powders, including larger bulk sizes.
  • Whole Foods Market: As a premium grocery store, Whole Foods carries Quest products, but prices may be higher than at a bulk retailer like Costco.
  • Vitamin Shoppe / GNC: Specialty health and nutrition stores will almost always have Quest products in stock and often offer deals on multipacks.

Strategies for Finding and Buying Quest Products

If Quest shakes are your top priority, here's how to maximize your chances of finding them, even with Costco's fluctuating stock.

  1. Set up Costco alerts. If you are a member and want to be notified when Quest shakes come back in stock on Costco.com, you can often sign up for email notifications on the product page.
  2. Use the Costco app. The Costco app can sometimes provide more immediate information on a specific store's inventory. Search for the product and select your local warehouse to check if it is available.
  3. Monitor social media. Follow Quest Nutrition and Costco on social media. They sometimes announce new products or restocked items in special promotions.
  4. Buy from a non-exclusive retailer. If you need Quest shakes consistently, purchasing from a retailer like Amazon or a health store is your best bet to avoid being disappointed by empty shelves.

Conclusion

So, does Costco sell Quest shakes? The answer is yes, Costco does sell Quest shakes, but predominantly through its website and with fluctuating availability. While you might get lucky finding them in a physical warehouse, relying solely on Costco can lead to disappointment due to their rotating inventory. For guaranteed stock and a wider selection of Quest products, you're better off checking online retailers like Amazon or health food stores. However, if you are flexible, Costco's consistent supply of competitive alternatives like Premier Protein and Fairlife provides excellent, high-protein options at bulk prices. The best approach is to check Costco.com for current online stock while keeping reliable alternatives in mind for a stress-free shopping experience.

Is there an easier way to get Quest products than waiting for Costco? Absolutely. While Costco can offer a great price, the uncertainty of its stock can be a hassle. For a wider selection and more reliable inventory, consider setting up a subscription on Amazon to get your favorite Quest products delivered directly to your door. This eliminates the need to constantly check inventory and allows for a more consistent supply of your protein shakes.
