Research on Taurine for Cats
A curated collection of peer-reviewed studies and clinical research on taurine's essential role in feline health — heart function, vision, immunity, and development.

The first studies on the effects of taurine on feline health began in the 1970s, when researchers discovered that cats cannot synthesize sufficient taurine on their own — making it a truly essential dietary amino acid for the species.
The research that followed has revealed taurine's critical role across virtually every system in a cat's body: the heart, the eyes, the immune system, the nervous system, and reproductive health. A landmark 1987 paper in Science demonstrated that taurine deficiency was responsible for fatal heart disease in thousands of pet cats — and that supplementation could reverse it.
Despite improvements to commercial cat food formulations, modern processing methods — high-heat extrusion, canning, and sterilization — continue to degrade taurine content significantly. Research shows that heat-processed diets produce 100x greater taurine degradation by gut bacteria compared to the same diet frozen-preserved. Many cats may not be receiving optimal levels from diet alone.
