Ingredient breakdown
Good ingredients
Neutral ingredients
Ultrafiltered Skim Milk Blend
This is a concentrated milk source that has had water removed through ultrafiltration to increase protein content. It provides high-quality dairy protein and calcium but contains lactose, which can trigger dairy sensitivity.
Natural Flavors
Derived from natural sources to enhance the vanilla taste. While generally safe, the specific composition is proprietary and may be complex.
Monk Fruit/Stevia Leaf Extract
These are plant-based non-nutritive sweeteners used to provide sweetness without adding significant calories or sugar. They are excellent alternatives for those watching their blood glucose levels.
Lactase Enzyme
An enzyme added to help break down lactose into simpler sugars. It is designed to make the dairy base easier to digest for those with sensitivity.
Cellulose Gum/Gel
These are food additives used as stabilizers and thickeners to maintain the product's texture. They are non-digestible fibers generally recognized as safe.
