How often should you do a colon cleanse?

Most of what researchers know about safe colon cleansing comes from studies that aim to find ways to improve the colonoscopy procedure rather than to boost energy levels or treat intestinal problems. Most colon cleansing products supposedly help detox the colon or remove harmful substances, such as mucus and dry stool. Some people also use colon cleanses to help relieve constipation.
