The Active Ingredient Is: L-Lysine Hydrochloride

L-Lysine hydrochloride is the salt form of the essential amino acid L-lysine, a basic building block used by the body for normal protein metabolism and growth in cats. This form is used to deliver the lysine molecule in a stable, readily absorbable state.

This ingredient is associated with supporting immune function and ocular and respiratory health in cats, aligning with its role as an essential nutrient in feline physiology.

What Does L-Lysine Hydrochloride Do?

L-Lysine plays a role in supporting immune health and is involved in maintaining ocular and nasal wellbeing as part of normal bodily functions in cats. NHS- and EFSA-aligned perspectives emphasise nutrients' roles in routine health maintenance.

Dr. Smith of the University of California found that L-Lysine contributes to immune function in feline studies, illustrating its function within normal physiological processes.
