what kind of protein is starbucks using

Starbucks uses whey protein isolate in their protein drinks. This protein is dairy-based, derived from cow's milk, and is known for its complete amino acid profile. The whey protein isolate is unflavored, gluten-free, sugar-free, and further processed to remove fat and lactose. Starbucks blends this whey protein powder into 2% milk to create their protein-boosted milk, which is used in their new protein cold foams and protein lattes. These drinks offer up to 36 grams of protein in a 16-ounce (grande) serving. The use of whey protein isolate targets customers looking for high-protein options, especially those interested in muscle building and maintenance. However, because it is dairy- based, it may not be suitable for those allergic to milk or lactose intolerant individuals.
