The only thing that is in a therapeutic dose level is the Folic Acid, the rest are barely maintenance levels. The minerals are good because the trace minerals can be important for some diets. Adding a 1000 to 2500 mcgs of B-12 and D-3 and adding all of the antioxidants would be good. More B-6 (100-200 mgs) would also be good because B-6 is like a quarterback/director of many other B vitamins.

The chest pain may be a bit of acid reflux. I get that occasionally. A chewable antacid or sometimes, just a glass of water often resolves mine. It usually last for just a few minutes. I have never been able to find a cause. It just happens.
