L-Lysine Supplement
L-Lysine can’t be produced by the body, so it must come from diet or supplementation. This essential amino acid works as a building block for protein and plays an important role in feline body functions and overall health. NaturVet’s immune supplement contains added antioxidants that work synergistically with the L-lysine, to help support strong immunity and eye health in your cat.
