Probiotics from Synbiotics are made up of probiotics such as Bifidobacterium animalis and Lactobacillus rhamnosus. Probiotics are often useful for lactose intolerance. Probiotics are active microorganisms that colonize the body and regulate the balance of flora in the intestinal tract, promoting nutrient absorption as well as maintaining intestinal health. In addition, they have the ability to ferment lactose, which helps to alleviate the symptoms of lactose intolerance. Lactose intolerance is caused by the lack of lactase enzyme in the body to digest lactose. When eating dairy foods, the lack of lactase enzyme leads to the inability to digest and absorb lactose, resulting in symptoms such as diarrhea, bloating and abdominal pain. The condition is highly prevalent in the Chinese population. It is often recommended to avoid dairy products and take probiotic preparations or lactase enzyme for treatment. Therefore, probiotics are usually useful for lactose intolerance. However, it is still recommended to consult a doctor for proper and standardized treatment.
