So I’m going to be a naysayer here. I suggest you cut out all the sugars and artificial / processed stuff in both the supplement and the ice cream. A tub a month seriously? Go read the list of ingredients in any commercial supplement- it’s like a chemistry starter set.
Here’s a viable alternative based on 99.9% pure whey protein powder. There are a couple of these that are just powdered whey, no other ingredients.
Pure WPI / WPC to taste;
Frozen banana to taste;
Whole milk powder to proportions recommended on the packet;
Organic coconut oil to taste;
Organic cacao powder to taste;
Pure vanilla essence to taste;
Whiz and enjoy.
You shouldn’t need sweetener (please) but try minimal amount of coconut syrup or raw honey. More calories? Arc up the coconut oil! It’s 100% fat.
Variations; add frozen berries, mango or avocado to the above, subtracting something else, or don’t.
I believe this is better tasting than anything based on hydrologised soy protein and bits of “herring, mackerel, salmon, sardine, tuna cod”. (As I say, read the label)
