Citric acid is found in a variety of fruits and vegetables. High concentrations of it are found in lemons and limes, according to ScienceDaily.com, a medical news site. The natural preservative is often used to add a sour taste to foods and soft drinks. It is used in laxatives and in combination with acetaminophen and sodium bicarbonate as a medicine to relieve heartburn and acid indigestion. Medicine may be taken several times a day or for a few days. However, taking too much citric acid can create a variety of problems.
