K-Zyme is a source of potassium, combined with SOD and catalase, important antioxidant enzymes. Potassium is a very important mineral for the proper functioning of all cells, tissues, and organs in the human body. Potassium is crucial for cardiac function and plays a key role in skeletal and smooth muscle contraction, making it important for normal digestive and muscular function. Potassium is also important for maintaining normal blood pressure levels as well as for urinary alkalinization, which is necessary for proper mineral retention and xenobiotic excretion.
