Royal Canin Cardiac Diet is a special diet food used for heart disease and hypertension (increased blood pressure). Royal Canin Cardiac is enriched with flavanols. Flavanols from green tea improve blood flow to tissues and organs and slow down cell ageing. Furthermore, it contains less phosphorus. Heart disease is often associated with reduced kidney function, reduced phosphorus helps maintain kidney function. Also, the diet's sodium concentration is as low as possible and potassium and magnesium levels have been adjusted to reduce the workload on the heart. Finally, there is more taurine and L-carnitine in this food, to promote heart muscle cell function and cardiac contractility.
