When it belongs on your shortlist
You want a lower-protein-per-container option, rather than automatically choosing 30g or 42g.
The tradeoff to understand
Slate sells multiple protein lines. Classic 20g is not the same as the 32g or Ultra products. Check the exact line and can count.
What the numbers tell you
The manufacturer label for this classic chocolate variant lists 20g of protein and 100 calories per 11 fl oz container. That works out to 20.0g 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 2g 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: Ultra-filtered skim milk blend with water. This is a summary, not the full ingredient list.
This is a dairy product. The manufacturer calls it lactose-free, but it still contains milk proteins.
Sweeteners identified in the reviewed manufacturer information: monk fruit, stevia leaf Reb M. 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 Slate Milk Classic Chocolate 20g High Protein Milk Shake (24 Cans) | 20g Protein, 1g Sugar, 100 Cal - Real Ultra-Filtered Milk, Low Carb, Lactose Free, Breakfast Boost, Post-Workout, 11 oz. It confirms a listing title, not the formula of every unit a seller might ship. Verify the selected variation, 24-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 Slate 30g nutrition and 42g ultra lines and caffeinated lattes.
- Classic ingredient list omits carrageenan; some other Slate lines use sucralose.
