FAQs
Is R1 Protein good if I am sensitive to lactose?
Whey isolate is filtered to reduce lactose, so some people find it easier than concentrate, but it is still a dairy product. Check the label on your pack for allergen details.
Why are the tub sizes different between flavours?
Tubs are filled by number of servings, and each flavour weighs slightly differently, so pack weights vary.
