A 25g serve (or 2 x tbsp) contains approximately 91-106 cals depending on the variant (Plant-based, Tummy, Premium) and flavour, then if you add 250 low fat milk it goes to approx 200 calories or more. You can increase calories further by adding 1/2 cup of fruit or vegetables to your smoothies. This is a great idea if you need to add more calories in your diet or if you are breastfeeding.
