While there are many people who use meal replacements to clean their colons, most doctors are under the opinion that it is unnecessary and potentially harmful. For example, some doctors will recommend colon cleansing in preparation for a colon examination, but you don’t need special products to do this on a regular basis because your colon will clean itself of any toxins. Additionally, cleansers such as Almighty Cleanse can also upset the balance established by your colon for absorbing water and sodium to maintain fluids and elctrolyte levels within your body. finally, for those concerned with constipation, the healthiest way to prevent this is to drink a lot of water and eat a diet rich in fiber (30-38 g for men and 21-25 g for women).
