I brought this last Wednesday and I've followed the instructions on how to make, 2 heaped scoops: I got severely ill on this for almost a week thinking I had a stomach flu. 1 flat scoop with half water and half calcitrim milk and a was fine for a day.

Please be careful in buying this as I've taken it to my doctor, they said the product had made me sick. Buy their sachets instead as they not only taste better but they have more vitamins and minerals in them, they taste great even when made with straight water.
