By adding spinach to your juices, you're providing your body with many great health benefits. One of the main ones is that spinach is very beneficial for the health of the cardiovascular system. Spinach contains Vitamins A, C and K which together can reduce cholesterol from building up on the blood vessel walls. This therefore reduces your risk of heart attack, stroke and heart disease. Also the magnesium that is found in spinach can aid to keep blood pressure and heart rhythm regular. Iron and Folic acid are also present in spinach, which means overall improved blood health, and also they aid in the prevention of anaemia.
