Re: Has taking vitamins helped you?
Sounds like you have a lot of things going on perhaps a nutritional/naturopathic consult would help ge tot the bottom of things...
As for vitamins helping, if you think about where we would get them from if not from a tablet...food! Being whole foods not refined or processed. Fruit and veg, grains and legumes. If any refining has gone on, or your digestion is poor or you have any chronic stressful events in your life you will not be getting ample levels of many nutrients, this includes vitamins and minerals.
You need vitamins and minerals for just about every reaction in your body to take place, form the fireing of neurons in your brain to burning of fat for energy. It makes sense that we function better when our body is getting the correct dosages. If your diet is not optimum (and whos really is these days) your are probably not meeting your basic needs.
Food allergies are another one to think about, as stomach upsets and skin problems have been linked to being lactose intolerant (inability to digest milk/dairy products). I know from personal experience most of my complaints dissapeared once I cut out milk!
Best of luck. Feel better.
