Silk Launches Protein-Packed Milk with More Muscle, Less Sugar

Silk is no stranger to the plant-based milk game, with offerings like Soymilk, Cashewmilk, Oatmilk, and even Silk Kids. Now, the brand is taking things up a notch with its newest innovation: Silk Protein Milk, available in both Original and Chocolate flavors.

This soy-based milk combines regular soymilk with soy protein isolate, giving it a serious protein boost. In a single cup, Original Protein Milk delivers 13g of protein, 8g of carbs, 4.5g of fat, just half the sugar of standard Silk Soymilk, and 130 calories, 62% more protein than the regular version. Chocolate lovers aren’t left out either: the Chocolate Protein Milk matches the 13g protein per serving while cutting carbs nearly in half, lowering calories, and trimming sugar for a smarter indulgence.

Down a full bottle and you’re looking at a hefty 78g of protein, 78g of carbs, and 840 calories in the Chocolate variant—enough to make this an unexpected mass-gainer option. Silk Protein Milk is now available wherever Silk products are sold, making it a convenient, protein-packed addition to smoothies, shakes, or straight from the glass.
