The Story Behind Leftose®: A Natural Enzyme with a Long History

When it comes to natural wellness, few ingredients have stood the test of time like lysozyme — a powerful enzyme discovered by Alexander Fleming, the same scientist who found penicillin, the world’s first antibiotic. Lysozyme is found in everyday sources like egg whites, as well as in areas of the human body such as the mouth, nose, and throat.

In these areas, it plays a key role in supporting the body’s natural ability to maintain a healthy and comfortable environment by helping to protect against unwanted bacteria and keeping things in balance.

Thanks to its natural origins and long track record of safe use, lysozyme has become a trusted ingredient in many wellness products worldwide — and it’s the foundation and hero ingredient of the Leftose® range.

Generations of Trust in Singapore Families

For over 40 years, Leftose® has been a household name in Singapore. Families rely on it for everyday support, while doctors, pharmacists and healthcare professionals dispense it regularly.

The Leftose® range is designed to support comfort in the upper respiratory tract, especially the mouth, nose, and throat. Made with naturally derived lysozyme, Leftose® products are non-drowsy, well-tolerated, and available in several convenient dosage forms for all age groups.
