The symptoms of irritable bowel syndrome can vary from person to person. There are people who experience symptoms of diarrhea with their irritable bowel syndrome while there are some people who experience constipation. Because of this, there are different effects of vitamins for irritable bowel syndrome. Vitamins generally cause chemical reactions in the stomach and these reactions can either be beneficial or harmful to a person's IBS. Here are some common effects of vitamins for irritable bowel syndrome:

1) Vitamin C - Also known as ascorbic acid, this vitamin has a laxative effect. People should be careful in taking this vitamin for irritable bowel syndrome as it can cause diarrhea when it reaches the stomach. People already suffering from symptoms of diarrhea should monitor their intake of vitamin C very closely.

Taking this vitamin for irritable bowel syndrome may also cause gas and bloating. This occurs when the acid of the vitamin reacts with the alkaline setting of the lower intestinal tract. You can try to observe this reaction by dropping a couple of mentos on a glass of diet coke.

2) Calcium - This vitamin for irritable bowel syndrome can have either a laxative or constipating effect on a person, depending on the type. People suffering from IBS should try to discover hat type of calcium is right for them:

a) Calcium carbonate - This vitamin for irritable bowel syndrome contains no magnesium and can relieve symptoms of diarrhea. This is the best vitamin for irritable bowel syndrome which is prone to diarrhea (IBS-D).

b) Calcium citrate - This type of vitamin for irritable bowel syndrome contains magnesium and thus, can trigger symptoms of diarrhea. This is the best for people who suffer from irritable bowel syndrome which is prone to constipation (IBS-C).

A good advice to follow when taking calcium vitamins for irritable bowel syndrome is to keep the amount at a maximum of 500 mg. This is in order to prevent triggering symptoms of irritable bowel syndrome. It is also a good idea to take this vitamin for irritable bowel syndrome with vitamin D as this helps in the absorption of these nutrients.

3) Iron - This vitamin for irritable bowel syndrome can be quite constipating. People taking this vitamin for irritable bowel syndrome are also prone to stomach upsets. It is also a known fact that Iron interferes with the absorption of calcium.

Tips in taking vitamins for irritable bowel syndrome:

1) Try to get balanced doses of your vitamins - When buying supplements, make sure that those supplements deliver the right amounts of vitamins you need. It is important that a certain supplement does not contain a megadose of any vitamin as this could trigger symptoms of irritable bowel syndrome.

2) Always take your vitamins with food - It is important that you not take your vitamins on an empty stomach. Doing so could increase the discomfort brought about by the chemical reactions caused by the vitamins. This is especially true with acidic vitamins like vitamin C.

3) Consult a pharmacist - Remember that there are different effects of vitamins for irritable bowel syndrome. If you are unsure regarding which vitamin supplement to take, you should get help from a pharmacist in finding the mildest vitamin for irritable bowel syndrome.

4) Take separate vitamins separately - Vitamins for irritable bowel syndrome also react in various ways with each other. For the best absorption of nutrients, you should try taking vitamins one type at a time.
