ReThink Ice Cream says it is the first and only completely “tummy-friendly” dairy ice cream made lactose- and A1-protein-free — both of which are needed to ensure the safe avoidance of digestive discomfort in those who respond adversely to dairy. ReThink is also the first-ever ice cream brand to infuse its flavors with marine collagen (it also uses whey isolate protein and prebiotic fiber). Comparable to the original recipe, the offerings will continue to be diabetic- and keto-friendly and gluten-free.
