Pharmacol Res Perspect. 2020;8(2). doi:10.1002/prp2.589 Kidney stones are often treated with citric acid as potassium citrate. However, consuming foods high in this natural acid — like citrus fruits — can offer similar kidney-stone-preventing benefits ( 3, 24). Summary Ciriminna R, Meneguzzo F, Delisi R, Pagliaro M. Citric acid: emerging applications of key biotechnology industrial product. Chemistry Central Journal. 2017;11(1):22. doi:10.1186/s13065-017-0251-y A test-tube study showed that it may treat or prevent human norovirus, a leading cause of foodborne illness ( 10). Beverages or food products that contain these fruits — such as ketchup in the case of tomatoes — also contain citric acid.

These same symptoms were not observed in people consuming natural forms of the acid, such as lemons and limes. Citric acid — in the form of potassium citrate — prevents new kidney stone formation and breaks apart those already formed ( 20, 21, 22).NatWest, Royal Bank of Scotland (RBS) and Ulster Bank, which are all part of the NatWest Group, will now shut at least 172 of their bank branches in 2023 and 2024. In either case, the scientists suggested that the symptoms were most likely related to the mold used to produce the citric acid rather than the compound itself. Summary One report found joint pain with swelling and stiffness, muscular and stomach pain, as well as shortness of breath in four people after they consumed foods containing manufactured citric acid ( 4). It’s also sometimes added to canned fruits and vegetables to protect against botulism, a rare but serious illness caused by the toxin-producing Clostridium botulinum bacterium.

For example, calcium citrate doesn’t require stomach acid for absorption. It also has fewer side effects — such as gas, bloating, or constipation — than another form called calcium carbonate ( 15, 16). Also known as the tricarboxylic acid (TCA) or Krebs cycle, these chemical reactions in your body help transform food into usable energy ( 11). Cairns TC, Nai C, Meyer V. How a fungus shapes biotechnology: 100 years of Aspergillus niger research. Fungal Biology and Biotechnology. 2018;5(1):13. doi:10.1186/s40694-018-0054-5 Autumn Statement: State pension confirmed to rise by 8.5% from April 2024 – while some benefits will go up by 6.7% Autumn Statement: Workers to pay less in national insurance – but rate cuts don't offset the freezing of personal tax thresholdsThe Chancellor Jeremy Hunt has today (Wednesday 22 November) announced a range of tax, benefits and savings measures. We round up the key announcements and what they mean for you. Martin Lewis: What the Autumn Statement means for you – including wages, benefits, pensions, ISAs, housing, national insurance and more Food and beverages use an estimated 70% of manufactured citric acid, pharmaceutical and dietary supplements use 20%, and the remaining 10% goes into cleaning agents ( 4). Food industry NatWest, RBS and Ulster Bank to close at least 172 branches in 2023/24 – here's the full list, plus alternatives Similarly, magnesium in the citrate form is absorbed more completely and more bioavailable than magnesium oxide and magnesium sulfate ( 17, 18, 19). May protect against kidney stones

No scientific studies exist investigating the safety of manufactured citric acid when consumed in large amounts for long periods. Mineral supplements, such as magnesium and calcium, may also contain citric acid (in the form of citrate) to enhance absorption. Disinfecting and cleaning Both employees and self-employed workers will pay less in National Insurance from next year, Chancellor Jeremy Hunt has announced in today's Autumn Statement.

Pharmaceutics. 2022;14(5):972. doi:10.3390/pharmaceutics14050972 Walker AF, Marakis G, Christie S, Byng M. Mg citrate found more bioavailable than other Mg preparations in a randomised, double-blind study. Magnes Res. 2003;16(3):183-191. Citric acid enhances the bioavailability of minerals, allowing your body to better absorb them ( 12, 13, 14). Citric acid protects against kidney stones by making your urine less favorable for the formation of stones ( 23). Sodas, juices, powdered beverages, candies, frozen foods, and some dairy products often contain manufactured citric acid.

Citrate — a closely related molecule of citric acid — is the first molecule that forms during a process called the citric acid cycle. Humans and other organisms derive the majority of their energy from this cycle. Enhances nutrient absorption

This is because producing this additive from citrus fruits is too expensive, and the demand far exceeds the supply. Summary The citric acid listed in the ingredients of foods and supplements is manufactured — not what’s naturally found in citrus fruits ( 4). While not naturally occurring, citric acid is also a byproduct of cheese, wine, and sourdough bread production.
