Phosphoric Acid
In plain words
The short version
The signature acidulant of cola drinks — provides the characteristic sharp 'bite'.
Why we flag it amber
It's permitted and generally considered safe, but there are a few reasons to be mindful — like sensitivities in some people, debated studies, or intake limits. The Safety section below explains the specifics.
Safety profile
ADI of 70 mg/kg body weight expressed as phosphorus. Long-term high intake (mainly from cola consumption) has been associated with reduced bone mineral density in observational studies — the calcium-phosphorus balance is the proposed mechanism. Strong erosive effect on tooth enamel.
