Atlet especially distance running athletes, vegetarian athletes, female athletes and athletes who consume meat less than 1 times per week had a risk of iron deficiency. Female athletes who have regular menstrual periods will have a risk of iron deficiency is higher when compared with male athletes. Once the athletes were also vegetarians compared with non-vegetarian athletes, although for this vegetarian athletes can be met through the selection of the consumption of vegetables or fruits that are appropriate. Especially for long-distance runners, tugs at the legs to run the hard surface can cause footstrike risk of hemolysis, namely rupture of red blood cells which is accompanied by the release of hemoglobin into blood plasma as a result of foot tugs on a hard surface.

In the body, iron is the main function in the production of oxygen-carrying component of hemoglobin and myoglobin. Hemoglobin contained in red blood cells and is a protein that serves to to transport oxygen to various body tissues while the myoglobin present in muscle cells and serves to store and distribute oxygen to the muscle cells. Besides functioning to produce hemoglobin and myoglobin, iron can also be stored in ferritin protein, hemosidirin in the liver, as well as in the spinal cord. As an indicator of the level of iron in the body, ferritin circulating in the blood can be used to assess iron status in the body.

Lots of iron contained in animal products, especially red meat, eggs and fish, besides a lot of iron also contained in various types of beans such as soybean and mung beans, various kinds of vegetables and fruits. In general, according to the source, efficiency of iron have different absorption in the body. Iron derived from animal products or also known as iron would be more easily absorbed by the body, while the iron is derived from vegetables and fruits, or the so-called iron-nonhem will be more difficult to be absorbed by the body.

Under Review Review National Health and Nutrition, many adults in America do not get enough magnesium in their diets!

For many people, the consumption of magnesium is not low enough to cause impairment, but not high enough to promote optimal magnesium status. Optimal levels of magnesium may help protect against heart disease, immune system dysfunction, and migraine.

Who may be at risk for magnesium deficiency?

People with gastrointestinal disorders that impair absorption – magnesium is absorbed in the intestines. If you have a gastrointestinal disorder that interferes with the absorption of magnesium, your body may be forced to dilute the magnesium stored instead. People with poorly controlled diabetes – Magnesium is lost in greater quantities in the urine of people with hyperglycemia. Alcoholics – between thirty and sixty percent of alcoholics have low levels of magnesium in the blood. Ninety per cent of patients going through alcohol withdrawal also has low levels of magnesium. People taking certain diuretics, antibiotics and anti-neoplastic medication used to treat cancer. These may affect magnesium absorption and excretion. Older adults may have lower dietary intake of magnesium. The elderly are also more likely to be drugs that can interact with magnesium.

The best way to get extra magnesium is a healthy diet.

In people with very low levels of magnesium, a doctor may suggest the replacement of intravenous magnesium or an oral magnesium supplement. Magnesium oxide has the highest percentage of magnesium carbonate, magnesium hydroxide and magnesium are its second-best options.
