Proteinex 15 comes in ready-to-use unflavored liquid (8 oz and 16 oz bottles) that mixes invisibly into juice, water, or soft foods without changing taste — ideal when a caregiver is fortifying meals for someone who won't drink a flavored shake. The same line is available as a 30 oz powder for facilities or households that go through larger volumes and want to control mixing. For grab-and-go dosing, Proteinex 2go arrives in single-serve 2.5 oz strawberry and watermelon bottles — small enough to finish in a few sips, which matters for patients who tire quickly.

Those who prefer a flavored full-size option can reach for the Lemon-Lime formula in 16 oz or 30 oz bottles, while Proteinex Liquid Predigested Protein in cherry provides 18 grams of protein per serving in a 30 oz ready-to-use bottle. A typical serving of Proteinex 15 supplies roughly 15 grams of protein with minimal volume, so nutritional goals are met without filling the stomach — a common hurdle with larger nutrition drinks.

Store bottles at room temperature and refrigerate after opening. If protein needs are tied to a specific condition, confirm serving amounts with a physician or dietitian, since renal and wound-care protocols vary.
