Can't comment on product fully yet as only been using it a few days but it tastes ok. I have been using it with just water it's not as sweet as others I have used but that has got to be a good thing and it goes thicker if u leave it in the fridge so u can tailor it to suit your needs.
Kept me full didn't feel hungry and had energy
Looking forward to see the results soon all being well.
Will definately buy more if I see results
