Q&A

Can you make it with skimmed milk or does it have to be made with water: Hi Elaine, This product can be mixed with milk or water. However, by mixing this with milk it will increase the amount of calories you are consuming. I hope this helps, if you have any further questions please email us at online@usn.co.uk. Thank you, Team USN
