Taurine
Taurine is an amino sulfonic acid aiding in cardiac function, eye health, immune system function, and multiple other systems (ambitious little guy). Found in meat-based proteins, taurine helps build proteins concentrated heavily in the heart muscles, the eyes, and the brain. L carnitine and taurine supplementation is important to consider, especially in pets prone to cardiac stress, because both are significant amino acids for dogs' and cats’ heart health.
