Health Verdict
Riboflavin is generally recognized as safe for regular dietary consumption within approved food limits.
Most variants of Riboflavin 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.
