Starbucks has jumped into the protein market with new coffee drinks boasting as much as 36 grams of protein per serving.
Launched on 29 September 2025, in the US and Canada to coincide with National Coffee Day, the chain's Protein Lattes and Protein Cold Foam are pitched as a convenient way to combine caffeine with a nutritional boost. However, health experts caution that the drinks may come with hidden trade-offs in terms of sugar, calories, and price.
