Consuming high concentrations of cinnamon may make medicines less effective

Researchers at the University of Mississippi investigated how cinnamaldehyde, cinnamon's main active compound, behaves in the body.
Their findings suggest while the spice is safe in small doses, higher concentrations could affect how some medicines are processed.
The study demonstrated that cinnamaldehyde can activate receptors that may accelerate the breakdown of certain medications, potentially reducing their effectiveness.
'Health concerns could arise if excessive amounts of supplements are consumed without the knowledge of health care provider or prescriber of the medications,' said Shabana Khan, a principal scientist involved in the study.
'Overconsumption of supplements could lead to a rapid clearance of the prescription medicine from the body, and that could result in making the medicine less effective.'
The study found cinnamon oil poses almost no risk of drug interactions.
But cinnamon bark, particularly Cassia cinnamon that's found in supermarkets as ground cinnamon, contains high levels of coumarin - a blood thinner.
"In contrast, true cinnamon from Sri Lanka carries a lower risk due to its reduced coumarin content," said Amar Chittiboyina, an associate director at the university.
"Coumarin's anticoagulant properties can be hazardous for individuals on blood thinners."
Billy Gurley, a principle scientist at the university and co-author of the study, said more research is needed to fully understand how cinnamon might interact with certain drugs.

"We know there's a potential for cinnamaldehyde to activate these receptors that can pose a risk for drug interactions," he said.
"That's what could happen, but we won't know exactly what will happen until we do a clinical study."
Cinnamon has been linked to several potential health benefits, including managing blood sugar, reducing inflammation, protecting against heart disease, and potentially improving memory.
Those interested in using it as a dietary supplement should check with their doctor first.
"People who suffer from chronic diseases - like hypertension, diabetes, cancer, arthritis, asthma, obesity, HIV, AIDS or depression – should be cautious when using cinnamon or any other supplements," Khan said.
"Our best advice is to talk to a health care provider before using any supplements along with the prescription medicine."

Urgent recall of paracetamol pills over ‘contamination' fears – as patients urged to check packets now
Two batches of the paracetamol have come under the recall - find out everything you need to know below DRUG ALERT Urgent recall of paracetamol pills over 'contamination' fears – as patients urged to check packets now Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) BATCHES of an over-the-counter paracetamol have been recalled over fears some pills could be "contaminated". The recall notice was issued by the Medicines and Healthcare products Regulatory Agency (MHRA) after a small number of pills were found to be "discoloured". Sign up for Scottish Sun newsletter Sign up 1 The pills have been recalled as a precautionary measure due to contamination following a small number of complaints of discoloured tablets within the pots Credit: Getty Two batches of paracetamol 500mg doses made by Chelonia Healthcare Limited come under the recall. The batch codes to look out for are 2312010 and 2312011, which can be found on the packaging. Also, the affected batches have an expiry date of the 30th and 31st of November 2027 and were distributed earlier this year. The alert said: "Patients or carers should check to see if they have received tablets from the listed batches of Paracetamol 500mg Tablets. "The batch number can be found on the label of the medicine bottle and on the outer carton. These tablets can only be obtained from a pharmacy with a prescription. "The number of tablets you will have been given will vary depending on your prescription and you may have only received a small number of tablets." The recall added the pills are white and capsule-shaped, with a score on the side. And if you find tablets that are discoloured in any way, in pots from the listed batches, you should contact your pharmacist or the healthcare professional who dispensed your prescription. Patients who may have taken the medication and experience an "adverse reaction" are also urged to seek medical attention. Furthermore, any suspected adverse reactions should be reported via the MHRA Yellow Card scheme. Beware 3 of the most dangerous medicines in the world - including one found in almost EVERY home The recall notice hasn't detailed what risk, if any, there is taking the medication. But previous cases involving discoloured paracetamol tablets have been linked to fungal contamination. A similar recall was issued in Europe in 2019 after batches of the medication were found to be contaminated with Penicillium citrinum. The MHRA has described the recall as Class 2, which means the defect may cause mistreatment or harm to the patient but is not life-threatening or serious. Chemists have been told to stop supplying the affected batches immediately. What packets have been recalled? Paracetamol 500mg Tablets PL: 33414/0126 Active ingredient: Paracetamol SNOMED code: 33554711000001108 GTIN: 05060014445506 Affected lot batch numbers Batch no. 2312010 - expiry date 30/11/27 - 100 tablets (pots) - first distributed 14/4/25 Batch no. 2312011 - expiry date 31/11/27 - 100 tablets (pots) - first distributed 15/5/25 The recall adds: "Quarantine all remaining stock and return it to your supplier's approved process." Paracetamol is one of the most commonly taken medications in the UK. It's estimated just under 6,300 tonnes are sold a year. It's widely available to buy over-the-counter at shops and pharmacies, but you may be able to get it on prescription if you have long-term pain.

New ‘poo pills' could flush out killer bugs that kill one million Brits each year
Find out how superbugs develop and spread below POO KNEW? New 'poo pills' could flush out killer bugs that kill one million Brits each year Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) SUPERBUGS, or drug-resistant infections, are projected to cause more than 39 million deaths between now and 2050. This means that, on average, over three people are expected to die from antibiotic-resistant infections every minute. Sign up for Scottish Sun newsletter Sign up 1 Scientists focused on the gut to kill superbug infections Credit: Getty But now UK doctor are attempting to clear the number of dangerous superbug infections by using pills containing freeze-dried faeces. The "poo pills" contain stool samples from health donors, packed with good bacteria. And the idea comes from previous data that suggests superbugs can be flushed out of the bowel and replaced with a mix of healthy gut bacteria. Dr Blair Merrick, who has been testing the pills at St Guys and Thomas' hospitals, said the focus is on the bowels which are "the biggest reservoir of antibiotic resistance in humans". The bowel is considered a significant reservoir for these resistant bacteria, and from there they can cause trouble in places such as the urinary tract or bloodstream. Dr Merrick added: "So there's a lot in 'can you get rid of them from the gut?" Currently, people with recurrent illness caused by hard-to-treat bacterium Clostridium difficile can be offered faecal transplants. Scientists noticed they also had the potential to get rid of superbugs. In a new study, published in the Journal of Infection, researchers focused on 41 patients who had an infection caused by drug-resistant bacteria in the past six months. They were given pills made from faeces which people had donated to a stool bank. What is Klebsiella pneumonia? Each stool sample was tested to ensure it didn't contain and harmful bugs. Undigested food was removed, and then it was freeze dried into a powder. The powder, contained inside a pill, can then pass through the stomach unharmed and reach the intestines, where it then dissolves. Twenty of the participants were given three sets of capsules on three consecutive days, while the rest received placebo pills. For those who took the capsules , the donor bacteria was detectable in their gut flora a month later. Dr Merrick told the BBC: "It's very exciting. There's a real shift from 20 years ago, where all bacteria and viruses were assumed to do you harm; to now where we realise they are completely necessary to our overall health." To help avoid getting superbugs, the NHS recommends practising good hygiene - wash your hands frequently with soap and water, especially before eating, after using the toilet, and after coughing or sneezing. Use antibiotics responsibly - avoid taking antibiotics for viral infections like colds or the flu, as they won't work. Even if you feel better, finish all of your prescribed medication to ensure the infection is fully treated. And don't share antibiotics - sharing can be harmful and can lead to resistance. Also, take preventative measures when travelling - choose food from reliable sources, and ensure food is properly cooked and handled, avoid drinking water that may be contaminated, and make sure you are up-to-date on all recommended vaccinations before travelling.

New fat jabs warning over ‘increased risk of cancer – as experts fear they ‘stop common medication working'
Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) WEIGHT loss jabs could prevent a medication taken by millions of women from working - and increase patients' risk of cancer. The British Menopause Society said the jabs could cause hormone imbalance in women taking hormone replacement therapy (HRT), particularly for those with obesity, putting them 'at increased risk of womb cancer'. 1 Women commonly take a progesterone pill along with oestrogen patches or cream Credit: Getty It follows warnings to women on weight loss medications to take effective contraception, as the jabs could render the pill less effective. That's because weight loss drugs Wegovy and Mounjaro - as well as diabetes jab Ozempic - can delay the absorption of pills taken orally, as well slowing down the passage of food through the gut. Guidance suggests women taking HRT in pill form may also be at risk. The British Menopause Society (BMS) told doctors to closely monitor menopausal women on HRT who are also using weight-loss jabs. The treatment tops up the hormones oestrogen and progesterone, which dip to low levels as the menopause approaches. Data from 2023-24 showed that 2.6 million women in England rely on the drugs to alleviate hot flushes, night sweats, difficulty sleeping and mood changes. "During the last two years, since semaglutide and tirzepatide [the active ingredients in Wegovy and Mounjaro] received licenses for weight loss, there has been an increase in uptake of these medications through private clinics, while NHS prescribing is limited to specialist weight management services," the BMS guidance stated. "There are no current data available about numbers of women receiving HRT concurrently with semaglutide or tirzepatide." The most common form of HRT is a progesterone pill alongside a skin patch or gel to deliver oestrogen, but some people opt for a combined pill. Progesterone balances out the effects of oestrogen, which on its own stimulates the growth of the womb lining, and can cause 'abnormal cells and cancer' to grow. Women taking fat jabs need 'effective contraception' - as health chiefs warn of serious harm to unborn babies The menopause experts expressed concern over the loss of the progesterone's protective effect on the womb as a result of weight loss jabs. They recommended that doctors move women taking progesterone orally to an intrauterine device, such as a Mirena coil, or increase their dose of progesterone. Prof Annice Mukherjee, a consultant endocrinologist and member of the society's medical advisory council, who led on the guidance, told The Telegraph that a hormone imbalance could put women 'at increased risk of womb cancer' - particularly if they are obese. 'Oestrogen is almost always given through the skin for HRT in women living with obesity, but progesterone is frequently given as a tablet, and that formulation is thought to be the safest route for women who have complicated health issues,' she said. 'If we then start one of these injectable weight-loss drugs, then you're preferentially stopping absorption of the progestogen that's coming in orally, but you're allowing plenty of the oestrogen through the skin. 'The rules are very clear that if you give a very high dose of oestrogen and you don't give enough progesterone, however that happens, you're putting that woman at risk of womb cancer,' she said. Prof Mukherjee said there was currently a 'culture of putting women on very high doses of oestrogen', which can make the womb lining thicken. 'It's like having a lawn in a woman's womb. Oestrogen makes the lawn grow. Progestogen cuts the lawn. But if it's not being cut, it grows thicker, and then you can get abnormal cells and cancer.' Everything you need to know about fat jabs Weight loss jabs are all the rage as studies and patient stories reveal they help people shed flab at almost unbelievable rates, as well as appearing to reduce the risk of serious diseases. Wegovy – a modified version of type 2 diabetes drug Ozempic – and Mounjaro are the leading weight loss injections used in the UK. Wegovy, real name semaglutide, has been used on the NHS for years while Mounjaro (tirzepatide) is a newer and more powerful addition to the market. Mounjaro accounts for most private prescriptions for weight loss and is set to join Wegovy as an NHS staple this year. How do they work? The jabs work by suppressing your appetite, making you eat less so your body burns fat for energy instead and you lose weight. They do this my mimicking a hormone called GLP-1, which signals to the brain when the stomach is full, so the drugs are officially called GLP-1 receptor agonists. They slow down digestion and increase insulin production, lowering blood sugar, which is why they were first developed to treat type 2 diabetes in which patients' sugar levels are too high. Can I get them? NHS prescriptions of weight loss drugs, mainly Wegovy and an older version called Saxenda (chemical name liraglutide), are controlled through specialist weight loss clinics. Typically a patient will have to have a body mass index (BMI) of 30 or higher, classifying them as medically obese, and also have a weight-related health condition such as high blood pressure. GPs generally do not prescribe the drugs for weight loss. Private prescribers offer the jabs, most commonly Mounjaro, to anyone who is obese (BMI of 30+) or overweight (BMI 25-30) with a weight-related health risk. Private pharmacies have been rapped for handing them out too easily and video calls or face-to-face appointments are now mandatory to check a patient is being truthful about their size and health. Are there any risks? Yes – side effects are common but most are relatively mild. Around half of people taking the drug experience gut issues, including sickness, bloating, acid reflux, constipation and diarrhoea. Dr Sarah Jarvis, GP and clinical consultant at said: 'One of the more uncommon side effects is severe acute pancreatitis, which is extremely painful and happens to one in 500 people.' Other uncommon side effects include altered taste, kidney problems, allergic reactions, gallbladder problems and hypoglycemia. Evidence has so far been inconclusive about whether the injections are damaging to patients' mental health. Figures obtained by The Sun show that, up to January 2025, 85 patient deaths in the UK were suspected to be linked to the medicines. But she also stressed that the biggest risk factor for womb cancer was obesity - meaning that on the whole, weight loss jabs can cut the risk of disease. 'These drugs reduce the risk of cancer,' Prof Mukherjee said. 'But if they are prescribed to a woman who's on oestrogen through the skin, and she might already have womb thickening because she's living with obesity, and she's not absorbing the progesterone because she's been put on a weight-loss injection, she's potentially getting loads of oestrogen on top of her thickened womb lining, and that could potentially unmask cancers that are there or drive an early cancer to a more advanced stage.' The BMS put together the guidelines after calls from GPs for advice to give to patients. Dr Janet Barter, the president of the Faculty of Sexual and Reproductive Healthcare, told The Telegraph that weight loss jabs can cause side effects such as "vomiting and severe diarrhoea in some patients'. 'Obviously this could render any medication, such as HRT tablets or oral contraception, ineffective if there hasn't been enough time for them to be fully absorbed,' she said. 'If these side-effects are occurring, then people should discuss the matter with their doctor or specialist clinician to find the combination of drugs that's right for them.' Sun Health has contacted Novo Nordisk and Eli Lilly - the makers of Wegovy and Mounjaro - for comment. It follows warnings from the Medicines and Healthcare products Agency (MHRA) that GLP-1 weight loss drugs could reduce the absorption of contraceptives, due to the fact they slow down the emptying of the stomach. The watchdog also said the jabs should not be used during pregnancy, while trying to conceive or breastfeeding, over fears they could lead to miscarriage or birth defects. The MHRA explained: 'This is because there is not enough safety data to know whether taking the medicine could cause harm to the baby.' Dr Bassel Wattar, a consultant gynaecologist and medical director of clinical trials at Anglia Ruskin University, told The Sun: 'It's not the medication itself, but the weight loss that helps regulate a woman's hormones allowing her ovaries to function properly again. 'Pregnancy is more of a happy side effect.'
