Phosphoric Acid
What is Phosphoric Acid?
Phosphoric Acid is an inorganic acid that is primarily produced by reacting phosphate rock with sulfuric acid. It is a colorless and odorless liquid used in various industries.
In the food and beverage industry, phosphoric acid is commonly used as an acidity regulator and flavor enhancer in soft drinks, providing a tangy taste. The evidence on its health impact is mixed; while it is generally recognized as safe by food safety authorities, excessive consumption in sodas has been linked to lower bone density in some studies.
When you see phosphoric acid on a label, it is typically used to adjust the acidity and enhance flavors, especially in cola beverages.
Commonly found in: sodas, processed foods, cheese, baked goods, canned foods
What to watch
- Phosphoric acid in sodas has been associated with lower bone mineral density.
- Excessive intake can lead to tooth enamel erosion.
Phosphoric acid is approved by the FDA as a direct food additive and is generally recognized as safe (GRAS).
There is mixed research on phosphoric acid, with some studies linking it to negative impacts on bone health, particularly in high-soda consumers.
Phosphoric acid is not derived from animal sources and is generally considered vegan.

Scout's take
Industrial acidulant that gives cola its signature tang. Independently associated with reduced bone mineral density and higher osteoporosis risk in long-term observational studies (Tucker et al. 2006); also one of the most enamel-erosive compounds in any common beverage (pH ≈ 2.5).
The case against
At very high chronic intake can affect calcium absorption, but at beverage levels this is not a concern.
