3 min read

According to official product listings, Costco does indeed carry Boost protein shakes, though availability can differ significantly between warehouse locations and online stores. This guide explores where you can find Boost protein at Costco, the specific product types they carry, and what to do if it's not in stock.

Quick Summary

Costco carries Boost protein products, but availability fluctuates by region and purchasing channel (online or warehouse). Popular alternatives like Premier Protein and Orgain are also widely offered for customers seeking bulk protein options.

Key Points

Availability Varies: Yes, Costco sells Boost protein, but stock is not guaranteed and fluctuates based on location and online inventory.
Check Online First: The most reliable way to find Boost is by checking the Costco website or app for current warehouse and delivery availability in your area.
Business Centers Offer Options: Costco Business Centres may carry different Boost varieties and bulk sizes than standard warehouses, and membership rules differ.
Popular Alternatives Exist: If Boost is unavailable, popular and comparable alternatives like Premier Protein, Orgain, and Kirkland Signature are typically in stock.
Consider Nutritional Needs: Compare the nutritional content of Boost against alternatives like Premier Protein to ensure you choose the best shake for your specific health goals.
Buying in Bulk Saves Money: Purchasing protein shakes like Boost in bulk from Costco often results in significant cost savings compared to other retailers.
Stock Up When You Can: Because availability can be inconsistent, it's wise to buy Boost in larger quantities when you see it in stock to ensure you have a supply.

Yes, But Availability Is Key

While many assume that Costco stocks all major brands consistently, the reality for Boost protein is more complex. The company's inventory varies widely based on geographic location, warehouse size, and stock levels. This means you might find large multipacks of Boost in one store, while another may only carry a competitor's brand. Checking online is the most reliable first step to see what is currently available near you or for delivery.

Where to Find Boost at Costco

When searching for Boost, there are a few distinct channels to check. Your best bet is to look at all of them, as they may offer different products or stock levels.

In-Warehouse: Many standard Costco warehouses stock specific Boost varieties, often High Protein or Glucose Control, typically in large cases of 18 or 24 bottles. The selection is usually limited to one or two flavors, and stock can be inconsistent. Always call your local store or use the Costco app to check availability before making a special trip.
Costco.com and Same-Day Delivery: The online selection on the main website or through same-day delivery partners often mirrors warehouse inventory but with more up-to-date stock information. You can enter your zip code online to see what products are available for delivery, including specialized options like Boost Glucose Control.
Costco Business Centre: These centers cater to businesses but are accessible to all Costco members. They may carry different versions of Boost or other nutritional products, sometimes in even larger quantities. For example, Canadian Business Centres have listed Boost High Protein and Boost MEGA.

Specific Boost Varieties Found at Costco

Costco typically offers Boost in convenient, bulk packaging, focusing on their most popular formulations. Based on past and current listings across different regions, the following types have been spotted:

Boost High Protein: A common find, often in chocolate or vanilla flavors, packaged in large cases.
Boost Glucose Control: Specifically marketed for individuals managing blood sugar, this variety has also appeared on Costco's same-day delivery platform.
Boost MEGA: Some markets, especially in Canada, have featured Boost MEGA, which provides a higher protein content per serving.

How to Check Costco Stock Online

To save time and avoid disappointment, use these steps to check for Boost availability:

Visit Costco's main website and navigate to the "Health & Personal Care" section.
