There is limited evidence to support the claim that multivitamins can prevent aspirin's stomach side effects. Aspirin is known to cause gastrointestinal (GI) side effects, such as stomach ulcers and bleeding, due to its ability to inhibit prostaglandin production, which helps to protect the stomach lining [1]. However, some studies have investigated the potential benefits of multivitamins in reducing aspirin-induced GI toxicity.

One study published in the Journal of Clinical Gastroenterology found that a multivitamin containing antioxidants, such as vitamin C and E, may help to reduce aspirin-induced gastric damage in healthy individuals [2]. The study suggested that the antioxidants in the multivitamin may help to neutralize free radicals generated by aspirin, thereby reducing the risk of gastric damage.

Another study published in the European Journal of Gastroenterology and Hepatology found that a multivitamin containing omega-3 fatty acids, vitamin D, and calcium may help to reduce aspirin-induced GI bleeding in patients with cardiovascular disease [3]. The study suggested that the omega-3 fatty acids in the multivitamin may help to reduce inflammation and improve the integrity of the gastrointestinal tract.

However, it is essential to note that these studies had small sample sizes and were conducted in healthy individuals or patients with specific medical conditions. More research is needed to confirm the effectiveness of multivitamins in preventing aspirin-induced stomach side effects in the general population.

In conclusion, while some studies suggest that multivitamins may help to reduce aspirin-induced stomach side effects, the evidence is limited and more research is needed to confirm these findings.
