    Leftose is a type of natural enzyme that contains lysozyme hydrochloride as an active ingredient. Lysozyme is a natural enzyme found in many human body secretions, including tears, saliva, and breast milk. It may play a critical role in the human immune system by breaking down bacterial cell walls, thus protecting the body from infections.

     

    These tablets are primarily prescribed and marketed as a natural non drowsy remedy to soothe sore throats, and provide fast relief from flu and the common cold. They are available over-the-counter and are available at leading pharmacies in many countries worldwide. Leftose is a brand name for lysozyme hydrochloride, which is manufactured by the Japanese pharmaceutical company Taisho.

    How Does Leftose Work?

    Leftose claims to work by reducing inflammation and relieving pain associated with sore throats, flu, and the common cold. It is thought that the natural enzyme in the tablets breaks down bacterial cell walls, reducing the severity of the infection and promoting healing of the human body. Lysozyme also stimulates the production of white blood cells, which are responsible for fighting infections. This mechanism of action makes it supposedly effective in treating a wide range of infections caused by bacteria and viruses. In addition, they are said to be made from a non drowsy formula.

    Does Leftose Really Work For Sore Throats?

    According to the Health Sciences Authority (HSA) in Singapore, lysozyme-containing products have been phased out as therapeutic products due to the lack of evidence showing their efficacy compared to a placebo. This suggests that there may not be strong evidence to support the effectiveness of Leftose as a therapeutic product. 

     

    However, it is important to note that lysozyme is an enzyme that is indicated in the treatment of gastrointestinal disorders in infants, as well as Herpes zoster and Herpes simplex. Leftose may have potential benefits in treating these conditions, although further research is needed to confirm its effectiveness.

     

    It is also important to consider the potential risks associated with lysozyme-containing products. Lysozyme is primarily derived from eggs, which can cause allergic reactions in individuals with egg allergies. Physicians have been advised to exercise caution when prescribing lysozyme-containing products in patients with egg allergies because of the risk of a life-threatening reaction. It is therefore important for individuals with egg allergies to consult with a healthcare provider before taking this medication.

     

    In summary, while there is some indication that Leftose may have potential benefits in treating certain conditions, there is also a lack of strong evidence supporting its effectiveness compared to a placebo, Additionally, individuals with egg allergies should exercise caution when taking lysozyme-containing products.
