E1207 — Anionic methacrylate copolymer
Why it’s used
A synthetic, anionic polymer made from methacrylic acid and methyl methacrylate monomers. It is used as an enteric (gastro-resistant) film coating on tablets and capsules in solid dietary supplements, staying intact in stomach acid and dissolving only in the more alkaline small intestine to protect acid-sensitive nutrients or delay their release.

Regulatory status
No FDA GRAS notice or food-additive regulation was found covering anionic methacrylate copolymer for food use; in the US it appears mainly as a pharmaceutical/dietary-supplement enteric-coating excipient outside FDA's food-additive framework. Source (2026-07-24)
Authorised in the EU only as a glazing/coating agent for solid food supplements and solid foods for special medical purposes, added to Annex II of Regulation (EC) No 1333/2008 by Commission Regulation (EU) No 816/2013. Source (2026-07-24)
Regulatory status by region
The US has no dedicated food-additive or notified-GRAS determination for anionic methacrylate copolymer, so any US dietary-supplement use rests on unconfirmed self-GRAS or drug-excipient status rather than an FDA-reviewed food finding. The EU authorised it specifically and narrowly for solid food supplements and foods for special medical purposes via Commission Regulation (EU) No 816/2013, which amended Annex II to Regulation (EC) No 1333/2008.
The EU addressed anionic methacrylate copolymer in the same 2013 rulemaking as its neutral counterpart: Commission Regulation (EU) No 816/2013 inserted it into Annex II to Regulation (EC) No 1333/2008 as a glazing/coating agent limited to solid food supplements and foods for special medical purposes. That is a formal, EFSA-reviewed food-additive status the substance simply does not have in the US, where it functions only as a pharmaceutical enteric-coating excipient outside FDA's food-additive rules. The EU authorisation remains narrow by design, though — it does not extend to ordinary foods, so anionic methacrylate copolymer stays unauthorised for anything beyond supplement and FSMP coatings.
