Why it’s rated Avoid

A product’s rating follows its most concerning indexed ingredient. Each ingredient links to its science card and the research behind it. How ratings work

• Monosodium Glutamate (MSG – Synthetic) Concentrated Excitotoxin / Glutamate Receptor Over-stimulation
  Avoid
• Cosmetic Preservatives (Mild) Milder preservatives; limit rather than avoid.
  Use Caution
• Phenoxyethanol Synthetic Preservative / Mild Irritant in Concentration > 1%
  Use Caution
• Food Gums (Xanthan, Guar, Gellan) Generally safe; some people find gums irritate digestion. Limit, not avoid.
  Use Caution
• Citric Acid (Manufactured / Mold-Derived) Fermentation Byproduct / Mold & Inflammatory Response
  Use Caution
• Synthetic Fragrance / Parfum Undisclosed scent blend. A practical allowance: on its own it rates Caution (limit use), not Avoid — products with other flagged ingredients are still rated by those.
  Use Caution
