I have tried a lot of protein powders, Isagenix, Slim Fast, Herbal life, Arbonne , to name but a few, but I have never enjoyed any as much as I do Purition. The main reason being is that all other shakes are synthetic, in nature and in their after taste, You really dont have any of that with Purition powders. They keep me full , and make me feel like I am eating a good nutrionally balanced meal. My only important point to make is that they are not overly sweet. For me that is a good thing as I follow Keto and they are sweet enough , but compared to the synthetic powders that are loaded with unhealthy sweetners, they are noticeably less.
