In a nutshell
Phosphoric acid is a widely used inorganic acidulant and phosphorus source, safe within limits but watch Ca:P balance.
Consumer Advice
Phosphoric acid is an inorganic acid used mainly as the acidulant in colas and other carbonated drinks, and for pH adjustment and preservation. It is safe at authorised levels, but high intakes of phosphate have been linked to calcium loss from bone and extra strain on the kidneys, so heavy consumption of carbonated drinks is unwise. Drink them in moderation, especially if you have kidney problems.
