The digestive system is a system of tubes through which your food is passed during the various stages of digestion, and also organs that produce the chemicals needed to break down your food into the nutrients needed by the body. The digestive system begins with the mouth, where the teeth cut and grind the food, and mix it with saliva containing the enzyme amylase that begins the digestive process by converting starch into maltose and dextrin, which are later converted to glucose. Amylase cannot work in the acidity of the stomach, which is why you should chew starchy foods such as bread and potatoes before it is swallowed and passed down the esophagus to the stomach.

The stomach is a natural food processor, containing concentrated hydrochloric acid that breaks the food down into smaller molecules. Once the food has been mixed and processed it passes into the small intestine where the real digestion begins. The liver and pancreas manufacture digestive juices and pass them into the intestine as the food is expelled from the stomach. These juices are mixed with the food, break it downs chemically into nutrients which are then absorbed through the walls of the intestine. The waste is passed into the colon, from which they are later expelled.

While in the stomach, its glands produce not only the stomach acid but also enzymes that break up proteins into smaller compounds including amino acids. The liver produces a number of digestive juices, including bile that dissolves fats and renders them water soluble to be digested by enzymes from the pancreas. The liver also produces enzymes that further breaks down the food in smaller molecules.

The whole process is controlled by the digestive hormones that are generated by the stomach and small intestine, namely secretin, gastrin and CCK (cholecystokinin). These control the release of the various digestive juices and chemicals into the digestive system, and once the food has been broken down the nutrients are absorbed into the bloodstream and transported to the cells of the body where they are needed.

So, starting again from the top, how do discount vitamins and minerals help to support a healthy digestive system? First, we start with the teeth. It is essential for the proper use of food that it is shredded and ground properly before being passed to the body, and that the starches are broken down by the saliva enzyme amylase. The structure of your teeth is dependant on vitamin C and D, and the minerals calcium, phosphorus and magnesium. A deficiency in any of these would result in poor weak teeth, and your food would not be prepared properly for your stomach.

Vitamin B1 keeps your nerves in good working order, without which your appetite could not be regulated. Vitamin B3, or niacin, keeps the digestive tract in a healthy state and functioning properly. Vitamin B9, or folate (folic acid) carries out a similar task, and the B complex vitamins in general, then, keep the digestion process working smoothly and the peristaltic motion that moves the food along, also in good working order.

Manganese and chromium are essential minerals to the digestive system, without which enzyme activity would be limited and without chromium your appetite could not be controlled. Apart from that there is a lot that can go wrong with the digestive system and a good vitamin B complex or Vitamin B1 and B3 supplement, will help to maintain the proper functioning of the system. These vitamins will encourage proper control of the intestinal muscle function, and vitamins C and E will help deal with any inflammation in the bowel, or undue immune system activity. Acidophilus will also help to maintain a good population of healthy bacteria that are essential components of your digestive system. A probiotic supplement taken as instructed should achieve this.

A little considered function of the digestive system, perhaps because it actually takes place in the liver rather than the alimentary canal itself, is the disposal from the body of toxin absorbed by the small intestine. This is the chemical transformation of certain molecules into a form whereby they can be rendered water soluble and expelled in the urine. Substances such as drugs, alcohol, paint fumes and so on are formed into other chemicals that might be even more toxic than the originals for a short time, and since oxidation is used in many of these reactions, free radicals might be formed that can harm the body.

This danger, which is indirectly caused by the digestion of these substances, can be relieved by maintaining a sufficient intake of antioxidants in the form of Vitamins A, C and E to neutralize them. Some liver disease is caused in this way by insufficient vitamin nutrition, and a good discount vitamin supplement can help to prevent it by destroying the free radicals as they are formed.

This detoxification process then proceeds to a phase where the biochemically converted molecules are rendered into the water soluble form so that they can dissolve in the blood and be extracted by the kidneys into the urine. For this, a good supply of the tripeptide glutathione, glycuronic acid and some amino acids is needed. A supplement of these should also help the detoxification process.

Other supplements that can help the digestive system are natural enzymes. These work whether taken on an empty stomach or with food. On an empty stomach, at least two hours after a meal, they will immediately go to work in your blood and improve its condition. Taken with a meal they will help digestion the fats and reduce food waste by improving absorption.

There are many ways in which you can help to maintain a healthy digestive system by the use of discount vitamins, although any problem with your digestive system should be referred to your physician since there are many serious conditions that need expert medical treatment. Vitamins, enzymes, probiotics and other supplements, however, can help to prevent many of these from occurring.
