There are afew things I failed to address about vitamins. I didn't mean to imply that vitamins are not useful, but mainly, you cannot assume it is a vitamin issue. Of course, the vitamin companies would like us all to believe that we can't get what we need from food, but it generally is not the case (kind of like a few chiropractors feel everyone needs regular adjustments).
Anyway, it makes the most sense to me to take care of one thing at a time. If you make all sorts of changes at one time, you can't know which treatment is effective and which is doing nothing. It is common for people to think low energy is due to a vitamin deficiency, but if you have chronic inflammation anywhere in your body, THAT can be the source of chronic fatigue. All the vitamins in the world will not help until the inflammation is addressed. Once you get that straightened out, then you can look at what supplements might be useful for you.
Your primary doctor can order screening tests for vitamin deficiency, but still, it might make sense to wait until you get the pouch/cuff issues sorted out. It is possible that if your gut inflammation is improved and your transit time slowed down, nutrient absorption may improve by itself. But, with things like iron, folic acid, vitamin D, and B12, you may want to get a head start, because they can take a while to get back on track. Plus, you may find out they really are not an issue, and then you can focus on other things.
Take care.

P.S. When all is said and done, you can fiddle with your vitamins all you want, as you don't need a prescription or doctor's permission to do it! Just don't go crazy and overdose on them.
