My wife is pregnant and her OB told her to talk Tums for the calcium. But the Tums that we bought last time are of many different colors (red, green, orange, etc) and we are very worried of the artificial color chemicals. Now we found the peppermint Tums are white in color. Can we assume that it doesn't have artificial color in it if it is white in color? Thank you for your advice.
The white tablets probably don't contain food dye, but you need to read the label to be sure. Look at the "inactive ingredients" list.
But, she should be aware that the calcium carbonate in Tums isn't always the most absorbable form of calcium. Calcium citrate tablets are a better choice, if you can afford the price difference. If not, she should take the Tums with food in order to maximize the absorption of the calcium.
