People with certain food intolerances may benefit from the change, the company said.

Fast food chain Steak ‘n Shake announced in a Nov. 13 alert on X that it is changing its milk and chocolate milk to A2 beginning Dec. 1.

Steak ‘n Shake said the shift was due to A2 being easier on digestion and may help some customers avoid discomfort. The company will source A2 milk from cows that “only produce A2 type protein” and are “never treated with growth hormone rBST.”
