My biggest tip is to let her know to keep having her vitamin levels checked. Our bodies don't absorb normally now and like i said they are finding more and more things that effects us. Most recently was the zinc; I'm so glad that when my regular doc sent me to a specialist to have my blood checked and he knew about the zinc problem. For all of these years I had problems with going to the bathroom way too much. It didn't have anything to do with what I was eating either. After a short time on the zinc (mine was way low) I no longer have that problem. To prove the point last week it started back up again and then after the 3rd day I remembered I hadn't taken my zinc all week; I took it and problem solved. I give my self my vitamin B shot each month and calcium and vitamin D and iron are also big problems. Some people have problems with potassium. I make a list when I go to my docs and then I make sure I get a printout of my lab results to monitor (the lab results will tell you what are the normal levels so you'll know how you are doing. This has a lot to do with strength and energy and vit D can cause you to endure more pain than necessary. It can also make you look older too. Just tell her to make sure her doctor stays on top of things. I don't rely on just my doctor; I push for a test that I need and follow.
