Hi Pabitra, Thanks for posting in HCM. I understand your concern. Intake of protein supplements work only if you continue your exercises. This means that if you are not exercising one should not take protein supplements unless indicated by lab test that there is less quantity of serum proteins. As far as possible, take proteins in natural forms such as egg, milk and pulses. Additional supplement is indicated only when there is a need. Taking excessive protein supplements can cause the following side effects: 1. Protein metabolism creates the waste products which can have direct effect on kidneys as they are excreted via kidney. 2. Excess proteins is not utilized by the body can not be stored and hence the metabolites can get converted stored as fat. 3. There can be a bone mineral loss and bone weakness. 4. Can amount to dehydration if your water intake is less. If you take some protein supplements that are advertised but do not show the full contents, you can have serious side effects as they can have some addition contents like steroids, which will cause more harm than good in long term. Hence it is important to go for the protein supplements by reputed companies only. Protinex is a scientifically formulated high protein supplement that supplies essential amino acids and is fortified with vitamins and minerals. Ensure Nutrition Powder provides complete and balanced nutrition. It contains protein, 26 essential vitamins and minerals, including antioxidants. It is up to you to choose which would suit you and ensure that you take it as a supplement to the regular intake of proteins naturally. Hope the information provided would be helpful. All the best.
