Potential Risks and Side Effects

  1. 01High-dose animal studies showed cancer in rodent forestomachs — an organ humans don't have, limiting direct relevance; the FDA and EFSA consider it safe at food-use levels
  2. 02Some studies suggest weak endocrine-disrupting properties at doses well above typical dietary exposure
  3. 03Rare allergic reactions, more common in cosmetic/topical use
