I have heartburn since I got pregnant. I have been taking Zantac which my doctor said is fine. It has to do with the baby and your stomach. My prenatal pills I find don't give me as much trouble if I take it with milk.
Take with meal or just after. Cut in half and take half at a time with breakfast and lunch. Or just try a different brand. Try a gummy version. Those are usually a lot milder.
I love the gummies and they taste great, my doctor says they have the same amount of vitamins we need and there's nothing wrong with them.
I was told if I get heart burn from it to take half at breakfast and half at dinner. Try that :) was also told it must be taken within thirty minutes of eating
