|Additive Summary||Calcium Carbonate (E170)|
|Essence||Calcium Carbonate or E170 is a natural mineral, an inorganic sald, used for the white coloring of food, supplements, and medicine.|
|Names||Chalk, E170, Calcium Carbonate, CI Pigment White 18, INS 170, CAS No. 471-34-1, CI 77220, and others.|
|Sourcing||Typically, it is derived from either ground limestone or by precipitation of calcium ions with carbonate ions.|
|Manufacturing||Most commonly this dye is manufactured by first calcinating (heating to remove, oxidize, render) limestone to create carbon dioxide (CO2) and quicklime (CaO). Then, the slaking process is used (controlled adding of water to transform quicklime to slaked lime slurry). Then, the outcome of that undergoes the carbonation reaction (CO2 is bubbled through that slaked lime slurry).|
|Application||Coloring (white, water-insoluble).|
|Acceptable Daily Intake||None determined.|
|Side Effects||Side effects with this dye are rather uncommon. Still, some people may encounter stomach pain, constipation, upset stomach, dry mouth, loss of appetite, increased urination, belching, vomiting, metallic taste, gas, and nausea.
Whereas if it comes to overdose, it can be violently harmful as any overdose on a vitamin or mineral which are otherwise essential to life. So, at extremely and unhealthily high amounts, it can cause kidney stones, headaches, bone pain, muscle twitching, coma, irregular heart rhythms, confusion, pancreatitis, acute renal failure, gall stones, milk-alkali syndrome, and more (but overdose with just additives is not possible).
|Benefits||It can help to boost overall Calcium levels in our system despite not being the most effective way of doing it (a poorly-absorbed Calcium form). Still, it can improve heart, bone, muscle health, fight against diabetes, ward off high blood pressure, aid cholesterol levels, and more.|
|Studies||12,020+ studies on Pubmed. 240+ studies on safety.|
|Health Knight Assessment
||Likely Harmless. | Category 1 Additive.|
|Products||It isn’t rare that Calcium Carbonate is used as a beneficial ingredient in supplements. It is also used as an additive in supplements very frequently. It can be found in supplements like the Dr. Ohhira Probiotics, Solgar Male Multiple, Nature Made Vitamin D3, and others.
It can be used in processed foods like pizza, bread, soft drinks, chewing gum, cake mixes, cheese, candy, sweets, noodles, cereal, all kinds of bars, ice cream, pastries, cookies, biscuits, pies, tortillas, almond drinks, fish fingers, lasagne, food decorations, yogurt, cakes, chocolate, and others.
