FD&C Yellow #6 is a petroleum-derived synthetic dye adding yellow-orange color, but concerns exist about hyperactivity and allergic reactions.
FD&C Yellow #6 (Sunset Yellow FCF) is a synthetic azo dye used as a coloring agent in foods, drugs, and supplements. While it effectively imparts a yellow-orange hue, its use is associated with potential side effects, including hyperactivity in children and allergic reactions. Regulatory bodies carefully monitor and limit its concentration in products to ensure safety. The evidence regarding hyperactivity is mixed, and concerns about carcinogenicity have largely been dismissed with modern research at regulated levels.

Common Dosage
Dosage varies significantly depending on the application and regulatory limits. No general 'supplement' dosage exists as it's primarily a color additive.
Source Type
synthetic
Production Process
FD&C Yellow #6 is synthesized from aromatic hydrocarbons derived from petroleum through a process involving sulfonation, diazotization, and coupling reactions.

Inside BodyPotential Benefits
Coloring agents enhance the visual appeal of products, primarily influencing consumer perception. This benefit is aesthetic and does not offer direct health improvements.
Possible Side Effects
Hyperactivity in children presents as ADHD-like symptoms including increased motor activity, difficulty concentrating, and impulsiveness, potentially affecting social and academic well-being. This side effect can be difficult to distinguish from age-appropriate behaviors.
Allergic reactions are hypersensitivity responses to allergens, ranging from mild skin irritation to life-threatening anaphylaxis. Symptoms vary widely and are caused by an immune response.
Hyperactivity involves excessive activity, restlessness, and difficulty concentrating. It can be a side effect of medications or substances and may disrupt daily activities.
Scientific Evidence
Numerous studies on food colorings and hyperactivity, reports from regulatory agencies like the FDA and EFSA on acceptable daily intake levels, allergy case studies related to azo dyes.
