Absorbed calcium plays far less a role in constipation than calcium compounds in transit through the bowels do, and since calcium is required for muscle contraction, absorbed calcium actually normalizes peristaltic action (the waves of muscle contractions that move things through the bowel) thus helping to ensure efficient transit of contents through the intestinal tract. Calcium from a food such as the hydrilla verticillata in Super Natural Calcium is the least constipating of all forms of calcium.

Normal bowel function can be expected from a diet short on grains and refined carbohydrates, but containing plenty of fibre from fruits and vegetables and an adequate supply of probiotics, magnesium and Vitamin C.
