text: Nutrilite is the world oldest and largest nutritional supplement company. It's products are plant concentrates rather than synthetically produced isolated vitamins. A badly damaged kidney is going to have problems with virtually anything your sister puts in, so I'd be cautious with any new supplements, or indeed changes in diet. However, if her body is to try to repair itself, it will need the proper nutrients for her cells to function correctly. Being food concentrates Nutrilite is ideal for that. I'd recommend trying Daily and also Omega-3 and if all goes well swapping from Nutrilite Daily to Double X (if available) She may also need Iron as people with damaged kidneys are often anemic. Vitamin C may also be useful. Good luck!
