For shoppers prioritizing listed protein, sugar, calories and pack price, Nurri vanilla is the strongest Costco pick in the available listings. Costco Same-Day describes a 15-pack of 11-fl-oz bottles with 30g protein, 1g sugar and 150 calories per bottle. That is a label-based recommendation—not a claim that editors tasted or tested it. Costco’s assortment, local availability and prices can change.
Why Nurri is the pick
Nurri vanilla offers a useful combination of numbers for a ready-to-drink shake: Costco Same-Day lists 30g protein, 1g sugar and 150 calories per 11-fl-oz bottle. The listing also describes it as lactose-free and rBST-free and says it contains 10 vitamins and minerals. These are product and retailer claims, not independent findings about health effects.
The package is a 15-pack, and Costco Same-Day displayed it at $28.36 when accessed in 2026. Dividing that listing price by 15 gives about $1.89 per bottle, before any location-specific variation. The figure is a dated Same-Day listing snapshot, not a guaranteed warehouse price or a standing deal. Check your local listing before buying. See Costco Same-Day listings.

The per-bottle calculations use the listed package counts and snapshot prices; they are not a matched comparison of local, in-warehouse prices. Bottle sizes differ, and the Oikos listings report fiber while the Nurri listing cited here does not. If fiber or a larger bottle matters more to you than the stated calorie figure or pack price, Oikos chocolate or vanilla may be a better fit.

What to check before you add a case to your cart
- Price where you shop: Costco says availability and price can vary by warehouse or listing. Recheck the current item page or Same-Day basket total rather than relying on a past snapshot.
- Full nutrition and ingredients: Compare the package you will buy. The available product pages do not provide a consistent full nutrition-panel comparison across every Costco shake.
- Allergens and dietary fit: Review the current ingredients and allergen statement on the package. A lactose-free claim does not establish that a product is suitable for every dietary need.
- Your own needs: A 30g protein claim alone does not determine whether a shake is appropriate for you.
Other Costco shakes worth checking
Costco’s catalog has also listed Fairlife Nutrition Plan, Orgain 30g Ultra Filtered A2, Premier and other protein shakes. The available listings do not establish a consistent set of current nutrition details for those alternatives, so compare their actual labels and local package prices before choosing one. Assortment and stock can vary. Browse Costco’s protein shake listings.
