The first rule of digestion is never to get constipated. Long term constipation might be a side effect of low iodine and copper, see Iodine and Copper sections. It also may be liver and gallbladder congestion and lack of bile flow and production.  Try a Liver Cleanse!  Chronic constipation can cause hemorrhoids, impaction, leaky gut, and just isn’t fun. To prevent this, you can try several things.   First is drinking enough liquids and eating regular foods. Your digestive bacteria increase and multiply according to your eating habits. When you eat something new or strange, you may not have as much ability to digest the new food as quickly as your normal ones. Bread and high-starch vegetables can definitely slow you down in that way, and high-fiber vegetables can sometimes cause the same problem. Or maybe you aren’t eating enough fat consistently to keep the bile moving through your gallbladder, leading to lack of bile in your stomach to digest high-fat meals.  Second, try digestive enzymes, colostrum and/or a couple extra grams of Vitamin C, taken multiple times throughout the day. Third, add some SloMag or more Vitamin C before bed.  Remember when I said there were forms of Magnesium that would give loose stools? Magnesium Chloride is one of those, and if taken at bedtime, can help with regular bowels. Fourth, some form of an herbal complex (like Dr. Schulze’s listed below) could be a consistent, long-term solution that doesn’t include harsh laxatives.  Baking Soda may also be a great option (mix up to 1 tsp in a glass of water before bed).
