Frequently Asked Questions

How is "sugar-free" defined here?

Less than 0.5 g added sugar per serving. Natural milk sugars can still be present unless it is isolate.

What sweeteners replace sugar?

Common options are stevia, monk fruit, sucralose, or allulose. Check the label if you avoid certain sweeteners.

Does sugar-free whey taste worse?

Flavor varies. Sucralose is closest to sugar; stevia can leave a mild herbal after-taste. Sampling single-serve packs helps.
