I bought this product for my mother because she was really weak but it didn't work out for her. She had it for long time with milk as prescribed by the doctor but got disappointed. She used vanilla and chocolate flavour but nothing much happened to her. She was still the same. I would give 2 star to this product as it didn't work out for her and we didn't see any change in her body. The jar is made up of a low quality plastic, I also don't like the plastic container.
