Formulation Notes

Natural Factors Regularity Formula is a synergistic blend of standardized herbs that gently and effectively support bowel function.

Rhubarb root, a colon cleanser, complements the cascara. Gentian root is added for digestion while cool capsicum increases the effectiveness of the other herbs. Omega-3 fatty acids containing flax meal powder contribute to the intestinal lubricating of the bowel. Peppermint oil supports the gastrointestinal tract and increases bile production. Remember, consuming a fiber-rich diet, regular exercise and reducing stress may increase regularity over time.

Contains no artificial preservatives, color, dairy, sweeteners, starch, wheat or yeast.
