There are no regulators for herbal supplements, so the companies creating these cleansing supplements can add massive amounts of stimulant laxatives. Laxatives increase bowel movements and commonly cause diarrhea. In recent years, colon cleansing has become a popular choice for weight loss, but taking a laxative long-term will only lead to negative side effects. 4Life Tea4Life claims to support healthy digestion and colon cleansing. Dieters should only use a natural laxative like 4Life Tea4Life to treat occasional constipation, not as a weight loss supplement.
