Been having stomach problems: pain, cramp, bloating, constipated.. took these for half a year. Was trying to figure out whats goin on with my health. Went to see doctor, had ultrasound of all my organs, everything was normal so thankful to God! But stomach pain didnt go away. Its like something always bothered me. Under my left rib, from stomach to the left side. Then I realized that the only different thing Im doing is taking these vitamins. So I started researching every ingredient, every ingredient is in high doses! Specially b12. Too much iron too. As soon as I stopped taking them I felt so much better!. Was praying a lot for God to send me an answer! And one day when I was about to buy the refill I went on Amazon and i was like let me read reviews for this brand , I searched for negative reviews and omg! Lot of people having same symptoms! Stomach pain that you can even point with your finger where it hurts. Its just in upper stomach and upper left side. Oh and just remembered night sweats went away! I just started to feel so much better!
