The formula relies on many added vitamins and minerals, some gelling agents a bit of sugar, fats, and a protein source which is all soy based.

Their ready to drink formula comes in at 400 calories per 414 ml bottle, which is a significant amount of calories. Some weight loss shakes have only around 100 calories and they offer hours of appetite suppression.

Furthermore there is a total of 9 grams of sugar which is also high, as other brands have only 1 gram per serving.

While the 20 grams of protein is high, it is all soy based which for some people may not be suitable. Soy is known to be one of the most GMO produced crops, and in some it can lead to an increase of estrogen hormones.

The fiber is decent at 3 grams of serving but it would had been better had it had a bit more. Meanwhile the vitamin and mineral profile is rich.
