Answer: Citric Acid is not currently banned worldwide, but health agencies have flagged concerns. The FDA still allows it in US food. Risk level: low. Commonly found in: Coca-Cola, Powerade, Sour Patch Kids.
TL;DR: Citric Acid is allowed in the EU but allowed in the US (preservative).

Citric acid is a weak organic acid naturally occurring in citrus fruits. Commercial citric acid is produced almost entirely by fermentation of sugar substrates (typically molasses or corn syrup) using the mold Aspergillus niger. It is the most widely used food acidulant and preservative globally, also functioning as a chelating agent and flavor enhancer.
Acidifies and preserves foods and beverages, enhances flavor, chelates metal ions to prevent discoloration and rancidity, and is used in canned goods and beverages.
Generally recognized as safe. Excessive consumption can erode tooth enamel due to its acidic nature — dentists recommend rinsing with water after consuming highly citric drinks. A 2018 report in the journal BMJ Case Reports described a cluster of inflammatory reactions (joint pain, muscle weakness) in individuals who reported reactions specifically to industrially produced citric acid, hypothesizing residual Aspergillus proteins from the fermentation process as a potential cause. This remains a hypothesis without controlled clinical evidence, and regulatory agencies maintain its safety status.

Lemon juice, vinegar, and malic acid serve as natural acidulants for home use.
Industrial citric acid is produced by fermenting sugars with Aspergillus niger mold — not from lemon juice.
A 2018 BMJ Case Reports paper described a small cluster of inflammatory reactions; however, large-scale evidence is lacking and regulatory agencies consider it safe.
High consumption of citric-acid-rich beverages can erode tooth enamel over time. Rinsing with water helps.
No. It is universally approved and is one of the most common food additives worldwide.
