When it belongs on your shortlist
You want to compare a fiber-containing 30g dairy shake against ultrafiltered options.
The tradeoff to understand
This shelf-stable shake is not the refrigerated Oikos yogurt drink, and the manufacturer says it is not lactose-free.
What the numbers tell you
The manufacturer label for this vanilla variant lists 30g of protein and 170 calories per 12 fl oz container. That works out to 17.6g of protein per 100 calories, using the rounded label values. This ratio describes the formula; it does not tell you how it tastes or whether it is the best choice for your diet.
The label lists 5g of total dietary fiber. Compare the whole container with other whole containers, and keep the named flavor fixed. Different flavors and product lines can have different nutrition, sweeteners and container sizes.
Ingredients and dietary fit
Protein base in the reviewed manufacturer information: Filtered water, milk protein concentrate and micellar casein isolate. This is a summary, not the full ingredient list.
This is a dairy product. The manufacturer explicitly says it is not lactose-free.
Sweeteners identified in the reviewed manufacturer information: stevia extract. This summary is not a substitute for the full ingredient list, and we do not infer tolerance or health effects from a sweetener name.
Before ordering a multipack
Our Amazon API receipt identifies Oikos Protein Shake, Vanilla, 30g Protein, 12 fl oz, 12 Count | Shelf-Stable Ready-To-Drink Shake, Packed with 30g Protein, 5g Prebiotic Fiber, 1g Sugar, Easy Grab-And-Go Snack. It confirms a listing title, not the formula of every unit a seller might ship. Verify the selected variation, 12-count quantity, seller and current price at checkout.
A low pack price is only useful when the bottle count matches. Use the pack calculator to compare cost per container and per 25g of protein, including shipping and discounts on the same basis.
Research notes
- Distinct from refrigerated Oikos Pro cultured ultra-filtered milk drinks and Oikos Fusion.
- Chocolate label has 6g total fiber; front marketing refers to 5g prebiotic fiber. These are different measures, not a transcription error.
