Quinine
What is Quinine?
Quinine is a bitter compound originally derived from the bark of the cinchona tree, which is native to South America. It is a naturally occurring alkaloid and has been used historically for its therapeutic properties, particularly in the treatment of malaria.
In food and beverages, quinine is most commonly used as a flavoring agent, imparting a distinct bitter taste to products like tonic water. It is added in very small quantities, which are considered safe for consumption. However, the levels of quinine in food and drink are regulated due to potential health concerns.
When you see quinine on a label, especially in beverages, it's usually there to provide its characteristic bitter taste. It's important to be aware of any sensitivity you might have, as excessive consumption can lead to side effects such as cinchonism, which includes symptoms like tinnitus and nausea.
Commonly found in: tonic water, carbonated beverages, bitter lemon drinks, cocktails
What to watch
- Excessive consumption of quinine can lead to a condition known as cinchonism, characterized by symptoms like tinnitus, headache, and nausea.
The FDA permits the use of quinine in beverages with a maximum concentration of 83 ppm. It must be listed on the label if included.
Research notes quinine's historical use in malaria treatment, but acknowledges potential side effects at high doses or in sensitive individuals.
Quinine is plant-derived, so it is considered vegan-friendly.
