Iron deficiency and sleep quality in athletes -

Blood lost in this way may lead to iron deficiency or iron deficiency anemia. Gastrointestinal bleeding: Distance runners especially, but other athletes as well, may experience gastrointestinal bleeding.

Loss of blood in this manner can eventually lead to low iron levels or iron deficiency anemia. Heavy sweating: Iron is also lost through sweat. Because athletes sweat heavily during workouts and competitive events, it is important for them to replenish their iron stores either through food or supplements, or a combination of these nutritional approaches.

Hepcidin: The research also suggests that athletes are at increased risk for iron deficiency because of a hormone called hepcidin, which appears to spike after intense physical activity.

Hepcidin reduces blood iron levels. Importantly, hepcidin levels seem to peak between three and six hours after a hard workout. Meaning, many athletes who try to consume iron-rich meals in that time might not be absorbing the nutrient at all.

Athletes who develop low iron levels can experience the same symptoms as healthy, sedentary individuals. They may also notice signs of low iron more closely related to their training.

Note that many of the symptoms of iron deficiency can also be caused by over-training, making misdiagnosis common. A blood test can confirm low iron levels. There are two nutritional strategies for increasing iron levels: diet and dietary supplements, the latter of which will be discussed more in the next section.

As mentioned above, getting enough iron through diet alone can be difficult for many athletes, who often eschew certain foods and monitor their caloric intake. And as has also been mentioned previously, levels of the iron-reducing hormone hepcidin can remain increased for hours after a workout, making it difficult for the body to absorb iron from food during that time.

For athletes who train consistently, there may be few windows in which they can properly obtain dietary iron, making supplements a prudent choice.

Iron supplements can be used to help reverse low iron levels and to treat iron deficiency anemia in athletes. In fact, research has shown that iron supplementation can reverse any iron-deficiency-related athletic losses and improve exercise performance.

Floradix iron supplements also offer these additional benefits:. If you are an athlete who believes you may have low iron, you should talk with your doctor before adding an iron supplement to your daily regimen.

Your doctor may recommend that your iron levels be tested via blood work. This testing can verify if you are in fact deficient and in need of supplementation, and if so, the appropriate dose of iron to take in supplement form to help return your iron levels to a healthy range.

After you begin supplementing with iron, you should also have your iron levels re-checked every three to four months, as you may need to discontinue use once your iron levels are within a healthy range.

While iron deficiency has detrimental effects on the body, the reverse is also true, as too much iron can also cause health issues. Skip to content. F7CE6FEFB-AEBB5D Back to all posts. Why Is Iron Important for Athletes? Prevalence of Iron Deficiency in Athletes Instances of low iron levels and of iron deficiency anemia—a condition in which there are not enough healthy red blood cells to transport oxygen throughout the body, which develops due to insufficient iron—appear to be higher among athletes than the rest of the population.

Female athletes who eat a vegetarian diet seem to be at the greatest risk for insufficient iron. Sources of Iron Iron can be found in both animal-based foods and plant-based foods.

Why Are Athletes at Greater Risk for Low Iron? What Are the Symptoms of Iron Deficiency in Athletes? General signs and symptoms of iron deficiency include: 5 Fatigue, ranging from mild to severe Sleeplessness Headaches Dizziness Low energy during the menstrual cycle Pale, dry skin and mucous membranes Cracked corners of the mouth Brittle nails and hair, including hair loss Decreased memory, attention, and learning performance Signs and symptoms of iron deficiency specific to athletes include: 6 Decline in athletic capacity, including loss of endurance Decreased exercise performance Higher-than-normal resting heart rate or exercising heart rate athletes usually have a lower resting heart rate than more sedentary individuals Shortness of breath while exercising Nausea Frequent injury Loss of interest in exercise Note that many of the symptoms of iron deficiency can also be caused by over-training, making misdiagnosis common.

Eating More Iron: Foods That Boost Iron Levels There are two nutritional strategies for increasing iron levels: diet and dietary supplements, the latter of which will be discussed more in the next section.

The Benefits of Iron Supplementation Iron supplements can be used to help reverse low iron levels and to treat iron deficiency anemia in athletes. Floradix iron supplements also offer these additional benefits: Non-constipating Free of artificial additives, synthetic preservatives, alcohol, and lactose Kosher, non-GMO, and vegetarian Environmentally friendly packaging Available in multiple formats, including liquids, tablets, and a vegan, yeast-free, and gluten-free formula Iron Supplement Precautions If you are an athlete who believes you may have low iron, you should talk with your doctor before adding an iron supplement to your daily regimen.

Because iron is necessary for oxygen transport and energy metabolism, both of which are critical for fueling aerobic exercise, endurance athletes can experience a decline in exercise capacity and VO2 max, the maximal amount of oxygen the body can use, with iron deficiency.

As iron deficiency becomes more severe, the body cannot make a sufficient number of red blood cells and anemia, meaning low red blood cells, develops.

Athletes with iron deficiency anemia will generally have more pronounced symptoms than those with iron deficiency alone. A craving for ice chips is actually pretty specific to iron deficiency, so any athletes out there who find themselves wanting to eat a lot of ice should definitely have their iron levels checked.

Iron deficiency is diagnosed through blood tests. The most useful of the typical iron study panel is ferritin, which is a marker of iron stores. In the sports nutrition community, there is no clear ferritin goal for athletes. If a ferritin is dropping significantly during the course of a training cycle, this can also be indicative of developing iron deficiency and the need to intervene, even if the ferritin is within what is generally considered a normal range.

It is also worth mentioning that ferritin levels can quickly increase when the body is under stress so results may be falsely high during periods of active infection or inflammation.

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.
