Citric acid, widely known for its sour flavor and preservative properties, is found in many fruits like lemons and limes. While it's often safe for consumption, some manufactured forms can lead to allergic reactions due to residual mold components. It's crucial to differentiate between natural and synthetic citric acid as they may have varying effects on health. Allergies can manifest through symptoms such as joint pain, abdominal issues, and respiratory difficulties. Understanding the sources of citric acid can help consumers make informed choices about their dietary inclusions. This supplement aims to inform users about potential allergic responses and the importance of label transparency in food products containing citric acid.
