Dietary iron Dietary iron occurs in two forms: haem and non-haem. Iron metabolism and bioavailability The human body does not have a direct mechanism of iron excretion, hence, regulation of iron balance is influenced by the current iron status of the individual and the total amount of iron components ingested through the diet; and is maintained by the internal homeostasis [ 17 ].

Boosting brain power Deficiency ID is a spectrum of disease common in Athlets, especially among Ane and those that participate in endurance sports. There are two forms of ID: iron liw non anemia IDNA leveos, defined by decreased Immune-boosting exercises stores, Athlettes iron deficiency anemia IDAwhich is defined by a drop in iron stores and hemoglobin. Generally speaking, this is due to iron losses exceeding iron intake and absorption. Early on in the disease, athletes will have ID with normal hemoglobin levels, while in later or more severe phases of the disease they will develop IDA.

There are different stages of iron deficiency. The most severe state is iron deficiency anemia IDA which results in a host of symptoms, including weakness and fatigue. Two earlier stages can be identified that are precursors to IDA.
These are collectively referred to as iron deficiency nonanemia IDNA. The first and least severe stage of iron deficiency is marked by a fall in serum ferritin resulting from a reduction of total body iron stores, but other iron indices such as haemoglobin remain normal This stage is called nonanemia.
The second stage, also non-anemia, is marked by low serum ferritin but also low serum iron or decreased transferrin saturation and increased total iron binding capacity TIBC. Once iron stores and transport iron have been sufficiently depleted, the body can no longer keep up with the demands of hemoglobin synthesis, and the third and final stage IDA results.
Peeling et al. These are:. See infographic for the cut-off values used for each stage. The primary difference between IDNA and IDA is that the haemoglobin levels become impacted.
Once this occurs, it can start to impact exercise capacity because the body is not able to deliver oxygen around the body as efficiently. It is a good idea to plan periodic testing of iron status with your sports physician, especially if you are female, vegetarian, have a high training volume and are involved in endurance sports.
In the next blog we will discuss how iron deficiency can be prevented or treated. Peeling P, Dawson B, Goodman C, Landers G, Trinder D.

: Athletes and low iron levels| Why is iron so important? | It is important to consider other causes of fatigue, malaise and decreased exercise performance. Examples would include relative energy deficiency in sport, female athlete triad, hypothyroidism, diabetes, overtraining syndrome, sleep dysfunction and depression among many others. Iron is not synthesized by the human body and must be replenished by dietary intake. Dietary iron is difficult to replenish even in the non-athlete. This puts vegetarians at increased risk of ID Björn-Rasmussen Treatment is primarily aimed at iron supplementation and is generally an oral route. Indications for treatment are any degree of anemia and ferritin below normal cutoffs. The biggest side effect is gastrointestinal distress which makes compliance challenging Tolkien The best available evidence says that to avoid this GI toxicity, athletes should take mg every other day and will still have a similar increase in iron stores with less total iron ingested McCormick To maximize absorption, athletes should consume their supplement in the morning, 30 minutes prior to exercise to help potentiate absorption McCormick There are other oral formulations which are less commonly used but may be promising for future management. Answer A is the correct answer. This vignette is most consistent with iron deficiency anemia. The fatigue and decreased performance could be attributable to any of the answers. A normal blood glucose excludes diabetes. Overtraining syndrome and relative energy deficiency in sport are unlikely given the correct calorie intake, no changes in her training, no other stress related injuries and a normal body habitus. Her symptoms, sport of choice, gender and choice of veganism put her at high risk of iron deficiency. Because of the decrease in performance and fatigue she is likely anemic at this point. The patient needs serum hemoglobin and ferritin levels checked and perhaps a further workup if the diagnostic picture is unclear.

Iron is a critical component of heme formation, the protein chain responsible for carrying oxygen on hemoglobin. There is a direct correlation between iron stores, arterial oxygen content and maximal contractility of skeletal muscle. Ferritin is a storage protein which accurately reflects total body stores of iron and is a reliable marker of iron deficiency. It is worth noting that ferritin is an acute phase reactant which can be elevated following exercise or other inflammatory conditions. Hepcidin is a hormone which regulates iron metabolism. Hepcidin increases following exercise and while elevated, impairs iron absorption in the gastrointestinal mucosa Peeling Image 1. Athletes are considered more susceptible due to increased iron requirements. This is primarily due to hematological adaptations to training and sport requiring an increased oxygen demand. Iron loss can also occur due to sweating, hematuria and GI bleeding which may seem insignificant but can be cumulative over time Gaudin Foot strike hemolysis has also been implicated. In women, blood loss from menstruation Fallon and decreased iron consumption have also been cited as contributing factors Nickerson Iron deficiency non-anemic athletes typically are asymptomatic. When anemia is present, athletes will report lethargy, fatigue, weakness and shortness of breath. How to Get Enough Iron and Avoid Anemia. Iron deficiency is a common problem for women athletes. Studies have routinely found that athletes, especially female athletes, are often iron-deficient or anemic. Iron is essential for athletic performance. It is the component of hemoglobin in your red blood cells that transports oxygen to your cells and carries carbon dioxide away. Iron is also needed to maintain a healthy immune system. If you don't have enough iron you may be prone to more frequent infections. A combination of the following factors place athletes at risk of iron deficiency:. The symptoms of iron deficiency include loss of endurance, chronic fatigue, high exercise heart rate, low power, frequent injury, recurring illness, and loss of interest in exercise and irritability. Other symptoms include poor appetite and increased incidence and duration of colds and infections. Many of these symptoms are also common to over-training, so misdiagnosis is common. The only sure way to diagnose a deficiency is a blood test to determine iron status. If you experience any of the symptoms above, and you are in one of the higher risk categories, you should visit your healthcare provider for lab work. If your healthcare provider confirms iron deficiency , she will recommend an increase in your dietary iron intake. If your deficiency is severe, you may need supplements. Never use iron supplements unless under the supervision of your healthcare provider, as too much iron can cause irreversible damage and a higher risk of cancer and heart disease. The RDA for women and teenagers is 15 milligrams per day. Men should consume 10 mg. Endurance athletes may need slightly more. You can get iron in both animal and plant foods, but the iron in animal sources has an absorption rate of about 20 to 30 percent, while it reaches up to 10 percent for plants. You can also increase the amount of iron in foods you eat by cooking with a cast iron skillet especially if cooking acidic foods. Iron absorption from any foods, whether plant or animal, is decreased if they are accompanied at meals by caffeine. However, adding fruit citrus fruit in particular , to meals enhances iron absorption. The best sources of iron in the diet include: Lean red meat, iron-fortified breakfast cereal, nuts, and legumes, combined these with foods high in vitamin C. Smolin L, Grosvenor M. Athletes who follow a plant-based diet. Athletes with low energy intake because iron intake is more likely to be insufficient to support the demands of the body. Adolescent athletes because this time period is associated with increased iron requirements. Signs and symptoms of an iron deficiency include tiredness, lethargy, fatigue, paleness and shortness of breath.

| What Female Athletes Should Know about Iron Deficiency | Iron is used by red blood cells to help deliver oxygen all throughout the body. When iron levels are too low, bodily functions are negatively affected. Iron levels in the body can be low for reasons such as a diet deficient in iron, inadequate iron absorption in the stomach and intestines, or by loss of iron, which is a common cause in menstruating women. Iron deficiency ID is the result of low iron stores. Occasionally, iron levels may be low enough to cause anemia, which is known as iron deficiency anemia IDA. True anemia may have negative effects on immune function, cognitive abilities, and even athletic performance. This is particularly concerning to endurance athletes. A sports medicine physician will be aware of the association between low iron levels and decreased athletic performance, and will perform a thorough history and physical exam. Lab tests may be ordered, and are particularly important in assessing iron stores in the body. These include tests getting the level of hemoglobin, hematocrit, ferritin, and iron, among others. Routine screening for ID and IDA in female athletes and male endurance athletes is often recommended. An athlete with low ferritin and iron levels, and normal hemoglobin and hematocrit, is considered to have ID, but not IDA. If the athlete also has low hemoglobin and hematocrit levels, then he or she has IDA. For athletes with IDA, the evidence is clear that a daily oral iron supplement is beneficial in improving athletic performance. However, there is controversy about whether iron supplementation in athletes with ID alone is helpful. The decision to start iron supplementation in ID should be shared between the athlete, physician, and potentially, a dietician. Iron supplementation without knowing iron levels is not recommended. Iron is best absorbed in the form of food, as opposed to iron supplements, so increasing the intake of iron-rich foods is important to treating both ID and IDA. Iron-rich foods include animal protein such as red meat, chicken, and fish, as well as non-animal sources, including iron-enriched cereals and pastas, beans, and dark-green leafy vegetables. Iron supplement absorption is improved with vitamin C supplementation. Orange juice without calcium is a great option to take with the supplement. Iron supplements should not be taken with milk, coffee or calcium tablets, as these can reduce the absorption of iron. Finally, iron supplements can cause constipation, so increasing dietary fiber intake and considering a fiber supplement is important. Prevention Eating a healthy diet with foods rich in iron is a good way to help maintain normal iron stores in the body. As meat is a good source of iron, athletes who adhere to a vegetarian or vegan diet should be particularly careful to ensure adequate dietary iron consumption. Return to Play Athletes with symptoms like weakness, shortness of breath, or heart palpitations will likely have difficulty in competition, and exercise restriction may be considered until the athlete feels better. The other traditional iron panel tests can be useful in distinguishing iron deficiency from poor iron utilization states. A complete blood count CBC measures the levels of red blood cell in the body and determines whether or not someone is anemic. Markers of red blood cells in a CBC are hemoglobin and hematocrit. Of note, iron deficiency is only one of the many causes of anemia. Consultation with a sports dietitian is recommended for athletes with iron deficiency. A sports dietitian can perform a thorough dietary review and make recommendations for ways to increase iron intake. Replenishing iron levels through dietary means is always preferable to taking an iron supplement. For some, iron supplementation through oral means pill or liquid may be necessary. Oral iron comes in many formulations that are generally equally effective as long as taken regularly. Milk, coffee, and tea can interfere with iron absorption so should not be consumed along with the iron supplement. Unfortunately, oral iron can be difficult to tolerate due to side effects. Anecdotally, sports dietitians our clinic has worked with find that a specific iron product called Blood Builder is much better tolerated than standard iron supplements, though there is no directed scientific evidence to back this up. It is NEVER advised to make a self-diagnosis of iron deficiency. If an athlete is concerned that they might be iron deficient, they should get blood tests to confirm the diagnosis. Taking iron supplements in the absence of iron deficiency can lead to iron overload, which is very dangerous. There are also certain people that are genetically hardwired to absorb more iron and are at risk of iron overload even in the absence of high iron intake. Iron deficiency in athletes, particularly of the endurance variety, is common. Increasing iron in the diet is an important step in avoiding iron deficiency. Even so, our bodies only absorb a small portion of the iron we eat. Working with a sports dietitian can help an athlete find ways to increase dietary iron intake and absorption. Iron deficiency can make an athlete feel exhausted and decrease exercise capacity, but is easy to diagnose and generally not complicated to treat. If an athlete ever sees frank blood in their urine or stool, they should seek medical attention right away for a thorough evaluation. This can be very anxiety provoking in those unaware of this side effect as black stool is usually an indication that there is blood in the stool and may signal a GI bleed.
