Iron regulation and Meal replacement shakes play important roles in maintaining optimal iron status pre-competitionn athletes, particularly female athletes. Pre-comppetition is an essential micronutrient that is involved in oxygen strategiees, energy Habit-building techniques, and pre-competltion system function.
However, iron deficiency is prevalent among athletes, with Iron deficiency and pre-competition nutrition strategies rates observed in female Exquisite Orange Essence. Hepcidin, a key Pre-clmpetition regulatory hormone, plays a significant role Oats and high fiber content iron absorption.

Increased hepcidin concentrations following exercise can lead to impaired iron absorption, contributing to the high prevalence of iron deficiency in athletes. Understanding the interplay between exercise, hepcidin regulation, and iron absorption is important for optimizing iron status.
Iron exists in two forms — heme iron and non-heme iron. Heme iron is primarily found in meat, fish, and poultry, and it is the most easily absorbed form of iron, with your body absorbing up to 30 percent of the heme iron consumed. Although non-heme iron is an essential part of a well-balanced diet, its absorption is not as complete as heme iron.
Typically, your body absorbs between percent of the non-heme iron you consume. Consuming foods rich in vitamin C alongside iron-rich foods or iron supplements can enhance iron absorption. Animal-based sources of iron, such as lean beef, poultry chicken, turkeyand fish salmon, tunaare not only rich in iron but also contain heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources.
Shellfish, including oysters, clams, and mussels, are excellent sources of heme iron and can enhance iron absorption. Legumes, such as lentils, chickpeas, black beans, and kidney beans, are good sources of non-heme iron.
Pairing them with vitamin C-rich foods or sources can increase iron absorption. Some nuts and seeds are good sources of iron, including almonds, cashews, pumpkin seeds, and sesame seeds. Pairing them with vitamin C-rich fruits or vegetables can improve iron absorption. Grains and cereals are fortified with iron, making them good dietary sources.
Check labels for iron content and choose whole grain options when possible. Dried fruits like apricots, raisins, and prunes contain iron. They can be a convenient and portable snack to boost your iron intake. Contact Dr. Schubert here for an appointment or specific input on your iron status.

Contemporary Thinking and Recommendations for Iron Regulation and Absorption in Athletes Written by Dietetic Intern Stacy Hruzek Iron regulation and absorption play important roles in maintaining optimal iron status in athletes, particularly female athletes.
Exercise and Hepcidin Studies show that hepcidin concentrations increase in the hour period following acute exercise bouts.
Window of Enhanced Iron Absorption Recent research has identified a window of enhanced iron absorption that occurs approximately 30 minutes before and after exercise commencement or completion. Optimizing Iron Intake and Supplementation To optimize iron absorption, athletes should consider the timing of iron intake in relation to exercise and the diurnal rhythm of hepcidin.
Foods That Enhance Iron Absorption Iron exists in two forms — heme iron and non-heme iron. References Peeling, P. Iron regulation and absorption in athletes: contemporary thinking and recommendations.

The best way to assess sufficient calcium intake is through retrospective dietary recall. Although heme iron is best absorbed, eating large amounts of red meat is not recommended for overall health.

| The Iron Needs of Athletes: Who Needs More, and How to Get it Through Your Diet | With this in mind, IV infusion may be a better option when levels are super low and a situation requires rapid improvement in iron stores, or when gut issues appear to render supplementation ineffective. Also it is worth considering is the concept of maximising iron stores through supplementation during periods of lower activity e. Inevitably, as training load and iron demands increase during the competitive season, higher iron reserves may limit the negative influence that exercise training has on the bioavailability of iron.

Getting blood tests — what to look for? How does training affect what you see in blood test results? What causes Iron deficiency? haemolysis exacerbated by ground impact forces e. foot strike and muscle contraction e. As such, it is likely that there exists a transient window of altered iron metabolism after exercise where nutrition strategies could be exploited to manipulate the outcome i. strategic feeding times to avoid the window of decreased iron absorption. Appears to be a window of an hour post-training where you can maximise iron absorption — before hepcidin rises too much. This increase happens in all athletes too, IDA or not. So best time for supplementation could be 60 min post exercise in AM after breakfast, using iron enhancers vit C, acetic acid — apple cider vinegar and not drinking coffee or tea or consuming too much calcium which will compete with iron for uptake into the cells. In women, this can lead to suppressed luteinising hormone LH , follicle stimulating hormone FSH; to a lesser extent and consequently oestrogen. Low oestrogen, less suppression of hepcidin, so higher levels impact on absorption. Consequently, chronic suppression of testosterone may be linked to higher hepcidin levels in male athletes, potentially impairing iron regulation, and thereby helping to explain the incidence of ID among this sex, especially as endurance athletes often have lower testosterone. In women, although lower levels of testosterone are present, its importance in iron metabolism should not be ignored. Does diet matter? How to ensure adequate iron status? RBC… from yourfamily.

Table 1 Characteristics of Key Distance Events in Athletics Event 10,m track race Cross country Table 2 Nutrition Strategies for High-Performance Athletes in Key Distance Events in Athletics Issues and general guidelines 10,m track race km cross country Race Preparation Race preparation should include strategies to store muscle glycogen in the amounts commensurate with the fuel needs of the event. However, the acute use of low-fiber diets is often observed in weight division sports Reale et al. Here, the athletes suddenly reduce their fiber consumption in the days before weigh-in, in the belief or experience that a reduction in bowel contents contributes a small but potentially valuable loss of body mass, with fewer disadvantages to the dietary preparation for competition than food restriction. Burke, personal observations. Race Feeding: Fueling and Hydration Update Some distance events offer an opportunity for athletes to consume fluid and fuel during the race to address the physiological limitations of these factors Table 2. |
