Free from:
  • artificial sweeteners · by the listthe list has no ingredient of the “acesulfame potassium, aspartame, sucralose” group — a calorie-free sweetener, usually paired with sucralose or aspartame for taste. Permitted, a preference question.
  • colorants E102/E120/E150 · by the listthe list has no ingredient of the “caramel colour, carmine, tartrazine” group — a brown colour from caramelised sugar: it tints syrups and coatings and does not affect the action.
  • carrageenan · by the listthe list has no ingredient of the “carrageenan” group — a thickener from red seaweed. It is permitted but debated: in animal studies the degraded form irritated the gut, so people with inflammatory bowel disease are sometimes advised to avoid it. For food-grade carrageenan there is no such proof.
  • gelatin · by the listthe list has no ingredient of the “gelatin (capsule)” group — capsule shell of animal gelatin (usually bovine or fish) — not for vegetarians; for halal/kosher the source must be confirmed with the maker
  • soy lecithin · by the listthe list has no ingredient of the “soy lecithin” group — an emulsifier from soy: it binds fats with water and keeps a capsule from separating. With a soy allergy it is a reason to check the list.
  • titanium dioxide (E171) · by the listthe list has no ingredient of the “titanium dioxide (E171)” group — white coating pigment; banned as a food additive in the EU since 2022, permitted in Russia and the US

  • Vitamin C (as ascorbic acid) 1 g (1,000 mg works · the active ingredient — what the product is for; form: ascorbic acid
  • Rose Hips (Rosa canina) powder 25 mg base: coating, fillers · rose-hip fruit powder: a traditional “natural” vitamin C source, but tablets carry tens of milligrams of it — the vitamin C it contributes is not declared and is negligible next to the main dose
  • Other Ingredients: cellulose base: coating, fillers · filler that gives the tablet its bulk
  • vegetarian coating base: coating, fillers · a plant-based tablet coating instead of gelatin; it keeps moisture out and makes swallowing easier
  • magnesium stearate base: coating, fillers · tablet-pressing lubricant; contains negligible magnesium, not counted as the element; in powders — a slip agent; does not clog pores
