I took a vitamin B50 complex for over 30 years. The Trader Joe s brand I used to take was discontinued so I bought a good one at Whole Foods. I have a really sensitive system. This one includes PABA, inositol, and choline and I m not sure the previous one had those. I m having lots of gastric upset, burping, fatigue, acid reflux. Can these symptoms come from these 3 ingredients?
