In addition to its importance for digestion and energy, the liver acts as a detoxifier. These substances are then excreted through the kidneys. Thus, your kidneys must be functioning properly too in order to have healthy liver function. The liver also breaks down hormones like adenaline, estrogen, insulin, and aldosterone. As you can see, it is a vital organ, and needs to be taken care.
Many nutrients can help support the liver.
The liver has to work twice as hard if you are constipated. Be sure your diet contains plenty of fiber and bulk. Do not smoke and cut back on alcohol and coffee. Do not take more than 10,000 IU of Vitamin A on a ongoing basis, and avoid cod liver oil. Processed foods, white sugar, and white flour are very hard on the liver.
