Your vitamins are OK.
If you had a scab on your arm and kept picking it off,
it would never heal.Your colon is in an irritated state.This condition alone makes healing difficult.Than you eat wrong foods(raw lettuce,onion,grilled sandwich)that will scrap the colon wall and then wonder where the blood is coming from.Are you eating enough other fresh cooked vegetables? Broccoli,Brussel sprouts,brown rice,parsnip,turnips, asparagus etc they each have a different mix of unprocessed fibers,minerals and vitamins that could solve basic causes.What vitamins are you taking? An irritated colon has poor nutritional absorption and it therefore makes it necessay to take a multi-vitamin/mineral supplement.Good report.
