Health Verdict
Brilliant Blue is permitted in foods but recommended in moderation, especially for sensitive individuals.
Most variants of Brilliant Blue are synthetic or plant-derived. However, check individual packaging labels for animal-origin emulsifiers or processing aids.
Certain synthetic dyes and preservatives (like nitrites or benzoates) may trigger hyperactivity or allergies in children. Look out for safety warnings.
E-numbers starting from E100 to E199 range from natural plant extracts (like curcumin and beetroot) to synthetic colorants. Check the product label for specific sourcing.
