Proteinex should not be confused with something that will speed fast your protein intake and will help in body building. When our body age, the absorption power automatically reduces and this is when substitutes are required.
However proteinex is no doubt a safe supplement to your regular diet but is not always recommended. From my personal experience natural products should be the first one in the queue that you should take to boost up your health and inner stamina rather than completely and blindly depending on such substitutes.
This product doesn’t work for all individuals, so it’s quite obvious few may contradict and few may agree to what I say.
Always take natural diets enriched in proteins, and keep it natural as far as possible.
