Hello. I have cracked mouth. I was anaemic and had a blood transfusion. They don't necessarily hurt but they are usually red and occasionally crack. I'm on iron supplements. Why do you think they keep cracking?

Iron supplements can be rough
You need to take folic acid and vitamin C with it for better absorption.
Red meat is the richest source of iron. If you eat little or no red meat, make a special effort to include other sources of iron in your diet. Iron is found in fortified cereals, nuts, seeds, dried beans, dried fruit (apricots, peaches, raisins, and prunes) and dark green leafy vegetables. Cooking with iron pots and pans also increases the amount of iron consumed.

Certain factors influence the amount of iron absorbed from food. The iron in meat, fish and poultry is absorbed better than plant sources. Vitamin C can enhance the amount of iron absorbed in a meatless meal. Including vitamin C rich foods, such as fruits and leafy green vegetables in your meals, is a good way to promote iron absorption. Certain compounds in foods may slightly decrease iron absorptions, such as oxalic acid in spinach, phosphates in milk and egg whites, phytates in beans and other vegetables, and possibly the tannins in tea. Calcium supplements also may decrease iron absorption, so avoid taking them with iron-rich foods (e.g. take your calcium supplement with magnesium and Vitamin D at bedtime instead of at breakfast). To get enough iron, eat a wide variety of foods rich in iron, such as those listed in the following table. Consider starting your day with iron-fortified cereal and a glass of orange juice (for Vitamin C). Continue good nutritional habits by eating plenty of fruits and vegetables and iron-fortified breads throughout the day. Also take zinc 8 mg and copper 75 mg since Iron can deplete them from your system. Be careful not to take too much zinc and copper Copper (http://mmeade.com/cheat/copper.html)
If you experience constipation or it is green your Iron intake is too much for your body to handle.

Also drink plenty of water
