Origin & History
Natural habitat
Lysozyme (EC 3.2.1.17) is a naturally occurring glycoside hydrolase enzyme renowned for its potent lytic activity against bacterial cell walls, specifically by hydrolyzing β-(1,4) linkages in peptidoglycan. Abundantly found in egg whites, human tears, saliva, and other secretions, it serves as a critical component of the innate immune system. This broad-spectrum antibacterial agent supports immune function, gut health, and is widely applied in food preservation and therapeutic formulations.
“While the enzyme lysozyme was scientifically discovered by Alexander Fleming in 1922, its presence in natural substances like egg whites and human secretions meant its antimicrobial effects were indirectly utilized for centuries. Traditional practices, such as applying raw egg to wounds, intuitively leveraged its protective properties, which modern research now attributes to lysozyme's potent antibacterial action.”Traditional Medicine

Nutritional Profile
- Glycoside hydrolase enzyme (EC 3.2.1.17)
- Substrate specificity: Peptidoglycan (N-acetylmuramide and N-acetylglucosamine linkages)
- Source: Primarily chicken egg white (HEWL), also human secretions
How It Works
Mechanism of Action
Lysozyme functions as a glycoside hydrolase enzyme, specifically catalyzing the hydrolysis of β-1,4-glycosidic bonds between N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) residues within the peptidoglycan cell walls of bacteria, primarily Gram-positive species. Its lytic activity is facilitated by key active site residues, including Glu35, which acts as a general acid/base catalyst, and Asp52, which functions as a nucleophile to stabilize or form a covalent glycosyl-enzyme intermediate. This enzymatic cleavage disrupts bacterial cell wall integrity, leading to cell lysis and inhibiting pathogen growth.
Clinical Evidence
Extensive research, encompassing in vitro, animal, and human studies, consistently confirms lysozyme's potent antimicrobial activity, particularly against Gram-positive bacteria. These studies support its critical role in enhancing innate immune defense and modulating the gut microbiota by reducing pathogenic bacterial loads. Furthermore, research indicates its efficacy in mitigating systemic inflammation, contributing to overall health and immune balance.
Safety & Interactions
Lysozyme is generally considered safe, particularly when derived from non-allergenic sources or when consumed in typical dietary amounts. However, individuals with allergies to eggs should exercise caution as commercial lysozyme is often sourced from egg whites, potentially triggering allergic reactions. Currently, there are no well-documented significant drug interactions associated with lysozyme supplementation. Its use during pregnancy and lactation is generally considered safe due to its natural presence in human secretions, but medical consultation is always advisable.

Frequently Asked Questions
What is Lysozyme Enzyme?
Lysozyme is a naturally occurring glycoside hydrolase enzyme, also known as muramidase, produced by animals as a key component of their innate immune system. It functions by catalyzing the hydrolysis of specific bonds in bacterial cell walls, leading to bacterial lysis.
How does Lysozyme enhance immune defense?
Lysozyme enhances innate immune defense by specifically targeting and hydrolyzing the β-1,4-glycosidic bonds in the peptidoglycan cell walls of Gram-positive bacteria. This action disrupts the structural integrity of the bacterial cells, leading to their lysis and effectively inhibiting pathogen growth and reproduction.
Does Lysozyme support gut health?
Yes, lysozyme significantly supports gut health by selectively reducing the load of pathogenic bacteria within the intestinal tract. By targeting harmful microbes, it helps to create a more balanced and favorable environment for beneficial gut microbiota, thereby contributing to overall intestinal well-being.
What is the primary mechanism of action for Lysozyme?
The primary mechanism of action for lysozyme involves the enzymatic cleavage of the β-1,4-glycosidic bonds found between N-acetylmuramic acid (NAM) and N-acetylglucosamine (NAG) units in bacterial peptidoglycan. This hydrolysis is facilitated by key residues in its active site, such as Glu35 and Asp52, leading to the destruction of the bacterial cell wall.
Are there any known side effects or interactions with Lysozyme?
Lysozyme is generally well-tolerated, but individuals with egg allergies should be cautious as commercial forms are often derived from egg whites and may cause allergic reactions. Currently, there are no widely reported significant drug interactions. As with any supplement, consulting a healthcare professional is recommended, especially for pregnant or breastfeeding individuals.
What foods naturally contain Lysozyme Enzyme?
Lysozyme is naturally present in several foods including egg white, milk, tears, and saliva, where it serves as a natural antimicrobial defense. Other dietary sources include certain fermented foods and raw honey, though concentrations vary significantly. However, cooking and pasteurization can reduce or eliminate lysozyme activity, making supplemental forms more reliable for consistent intake.
Who should avoid taking Lysozyme supplements?
Individuals with known allergies to egg products should exercise caution, as lysozyme is commonly derived from egg white. People with autoimmune conditions affecting the gastrointestinal tract should consult a healthcare provider before supplementing. Pregnant and nursing women should seek professional medical guidance before use, as safety data in these populations remains limited.
How much Lysozyme Enzyme should I take daily?
Typical supplemental doses of lysozyme range from 50 mg to 1,000 mg daily, depending on the intended use and product formulation. Most clinical studies demonstrating immune or gut health benefits have used doses between 100–500 mg per day. It is recommended to follow the manufacturer's dosage instructions or consult a healthcare provider to determine the appropriate dose for your individual needs.
