Crude calculations reveal that if sweat iodide losses are not replaced, dietary stores could be depleted in an athlete undergoing a regular training regime. The significance of these losses could be increased in areas where dietary iodine intake is lower in the summer months. Although there is little doubt that excessive sweating can induce a relative iodine deficiency state, there is no case as yet for iodine supplementation in those that take vigorous exercise.

However, sustained iodine loss may have implications for thyroid status and possibly consequences for athletic performance. Peter P. Smyth M. smyth ucd. Year Archive Subscribe to RSS Please copy the URL and add it into your RSS Feed Reader.

Iodine is an essential fog mineral not made Iodone the body so must be Kidney bean Mediterranean recipes by food or supplements. Iodone is found naturally in some foods and is raet to Energizing herbal remedies and some salt seasonings. Iodine is needed Guarana Extract for Energy make the thyroid hormones thyroxine and triiodothyronine, which assist with the creation of proteins and enzyme activity, as well as regulating normal metabolism. Without enough iodine, these thyroid hormones do not work properly and can lead to an under-active or overactive thyroid gland, causing the medical conditions of hypothyroidism and hyperthyroidism with various negative side effects in the body. UL: A Tolerable Upper Intake Level UL is the maximum daily dose unlikely to cause adverse side effects in the general population. Production of thyroid hormones increases during pregnancy, requiring higher intakes of iodine.

Iodine for metabolic rate in athletes -

Thyroid hormones, thyroxine T4 and triiodothyronine T3 , are manufactured in the thyroid gland using iodine. Iodine consumed in the diet circulates in the bloodstream and is selectively taken up by the thyroid gland where, through a series of complex biochemical reactions, it is attached to tyrosine and eventually incorporated in the thyroid hormones T4 and T3.

These thyroid hormones are stored in the thyroid gland until a chemical signal from the pituitary gland, Thyroid Stimulating Hormone TSH , activates their release into circulation. Once in the cell, thyroid hormones help to regulate metabolism and create energy and body heat.

When thinking about thyroid hormones and athletic performance, you should first think about energy and its importance in athletic events. Hallmarks of thyroid deficiency are fatigue and low stamina, not something you want to find yourself plagued with at the starting block.

Every movement our body makes along with every thought process we have requires energy. Thyroid hormones play an important role in how our body creates and uses this energy.

Excessive sweating through exercise can leave you with less than adequate body stores of iodine, along with increased risk for thyroid deficiency and the potential for poor athletic performance.

This scenario can be compounded further for athletes on restricted or unbalanced low iodine diets that do not replenish the already low levels of body iodine caused by excessive sweating. A study 1 was one of the first to show how hot and humid environments cause increased loss of iodine through sweat.

Five males were shown to lose 2. This study demonstrated that those exposed to hot and humid environments, even without exercise, can lose a greater amount of sweat, resulting in a greater iodine loss than those exposed to cooler and less humid temperatures.

Two later studies targeted student athletes to determine iodine loss from sweat, comparing them to sedentary students. Rowing club students were the focus in 2 , and it was determined that during two hours of exercise students were losing up to an estimated four liters of sweat.

A similar study was completed in 3 that compared 13 soccer student athletes to sedentary students. The results were shocking. Another study completed in 4 collected sweat from Korean soccer players during a one hour game period.

The soccer players had been rigorously training for six months leading up to the study. Mean sweat loss was 1. Six of the 13 soccer players were diagnosed with goiter. The Table below provides a rough estimate of the average sweat loss, and thus risk for iodine deficiency, for different groups participating in physically challenging non-athletic and athletic events.

Each study shows that individuals who sweat excessively can be at risk for iodine deficiency if they do not pay special attention to replenishing iodine lost in sweat. Individuals not consuming the recommended daily intake of at least µg iodine 18 would, therefore, more likely suffer the consequences of iodine deficiency disorders which include fatigue, low energy, low stamina, and poor athletic performance.

We believe that special attention should be paid to replenishing urinary iodine levels in athletes whose performance results in excessive sweating.

Since the current iodine status of an individual can be determined easily with urine , iodine testing should be included in health monitoring of these individuals to identify and correct iodine deficiency before it compromises athletic performance and overall health.

Seafood such as shrimp, mussels and seaweed also contain high amounts of iodine. By regularly incorporating these foods into your diet, you can ensure that you are getting enough iodine. Salt can also contribute well to your iodine supply. Note, however, that sea salt, Himalayan salt and fleur de sel contain hardly any iodine.

However, you should keep in mind that iodized table salt always contains synthetically produced iodine, which may not be the best solution for your health. It is important to note that a balanced diet is basically the best way to get the nutrients you need, including iodine. In most cases, we can get enough iodine from our diet and do not need supplements.

However, it can be challenging to consume enough iodine-rich foods every day, especially if you have stress in your daily life or you travel a lot. An iodine supplement in the form of an easy-to-take capsule can provide a convenient and consistent supply of iodine to support your metabolism on a daily basis , regardless of your eating habits or circumstances.

Natural iodine comes from natural sources such as algae, especially kelp E. HELP FROM KELP Plant-Based Iodine from Ogaenics. It is better than synthetic iodine produced in the laboratory.

Your body can better absorb natural iodine. Natural iodine supplements such as those made from kelp e. Help From Kelp by Ogaenics also contain many other minerals and trace elements that benefit your metabolism and are good for you.

In summary, iodine plays a significant role in metabolism. An adequate iodine supply can boost metabolism, increase energy expenditure and support weight loss. It is important to include enough iodine-rich foods such as seaweed, fish and seafood in your diet every day, and to turn to supplementation when needed to ensure a normal metabolism and healthy fat burning.

A natural dietary supplement with iodine from algae can make your daily iodine supply easier if you are on the go a lot. html accessed on No products in the cart.

In some regions of the world, iodine-deficient soils are common, increasing the risk of iodine deficiency among people who consume foods primarily from those areas.

Salt iodization programs, which many countries have implemented, have dramatically reduced the prevalence of iodine deficiency worldwide [ 2 , 3 ]. Iodine in food and iodized salt is present in several chemical forms including sodium and potassium salts, inorganic iodine I2 , iodate, and iodide, the reduced form of iodine [ 4 ].

Iodine rarely occurs as the element but rather as a salt; for this reason, it is referred to as iodide and not iodine. Iodide is quickly and almost completely absorbed in the stomach and duodenum.

Iodate is reduced in the gastrointestinal tract and absorbed as iodide [ 2 , 5 ]. When iodide enters the circulation, the thyroid gland concentrates it in appropriate amounts for thyroid hormone synthesis and most of the remaining amount is excreted in the urine [ 2 ].

Intake recommendations for iodine and other nutrients are provided in the Dietary Reference Intakes DRIs developed by the Food and Nutrition Board FNB at the Institute of Medicine of the National Academies formerly National Academy of Sciences [ 2 ].

DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. These values, which vary by age and gender [ 2 ], include the following:.

Table 1 lists the current RDAs for iodine [ 2 ]. For infants from birth to 12 months, the FNB established an AI for iodine that is equivalent to the mean intake of iodine in healthy, breastfed infants in the United States.

Seaweed such as kelp, nori, kombu, and wakame is one of the best food sources of iodine [ 5 ]. Other good sources include fish and other seafood as well as eggs see Table 2. Iodine is also present in human breast milk [ 2 , 5 ] and infant formulas [ 8 ].

Dairy products contain iodine. However, the amount of iodine in dairy products varies by whether the cows received iodine feed supplements and whether iodophor sanitizing agents were used to clean the cows and milk-processing equipment [ 9 ].

Plant-based beverages used as milk substitutes, such as soy and almond beverages, contain relatively small amounts of iodine. Most commercially prepared bread contains very little iodine unless the manufacturer has used potassium iodate or calcium iodate as a dough conditioner [ 10 , 11 ].

Manufacturers list dough conditioners as an ingredient on product labels but are not required to include iodine on the Nutrition Facts label [ 12 ], even though these conditioners provide a substantial amount of iodine. According to data from the U.

Pasta is not a source of iodine unless it is prepared in water containing iodized salt because it absorbs some of the iodine [ 11 ]. Most fruits and vegetables are poor sources of iodine, and the amounts they contain are affected by the iodine content of the soil, fertilizer use, and irrigation practices [ 2 , 10 ].

This variability affects the iodine content of meat and animal products because of its impact on the iodine content of foods that the animals consume [ 14 ]. The iodine amounts in different seaweed species also vary greatly. For these reasons, the values for the foods listed in Table 2 are approximate but can be used as a guide for estimating iodine intakes.

The U. Food and Drug Administration FDA developed DVs to help consumers compare the nutrient contents of foods and dietary supplements within the context of a total diet. The DV for iodine is mcg for adults and children age 4 years and older [ 12 ].

FDA does not require food labels to list iodine content unless iodine has been added to the food. Products made without these conditioners contain very little iodine. The USDA, FDA and Office of Dietary Supplements-National Institutes of Health ODS-NIH Database for the Iodine Content of Common Foods [ 8 ] lists the iodine content of numerous foods and beverages.

The United States, Canada, and dozens of other countries have salt-iodization programs [ 3 , 16 , 17 ]. In the United States, salt manufacturers have been adding iodine to table salt since the s, although this practice is still voluntary [ 18 ]. FDA has approved the use of potassium iodide and cuprous iodide for salt iodization [ 19 ], whereas the WHO recommends the use of potassium iodate due to its greater stability, particularly in warm, damp, or tropical climates [ 3 ].

However, most salt intake in the United States comes from processed foods, and food manufacturers almost always use noniodized salt in these foods. If they do use iodized salt, they must list the salt as iodized in the ingredient list on the food label [ 9 ]. Specialty salts, such as sea salt, kosher salt, Himalayan salt, and fleur de sel, are not usually iodized.

Product labels will indicate if the salt is iodized or provides iodide. As shown in Table 2, noniodized sea salt provides virtually no iodine [ 8 ].

In dietary supplements, iodine is often present as potassium iodide or sodium iodide [ 20 ]. Supplements containing kelp, a seaweed that contains iodine, are also available.

A small study found that people absorb potassium iodide almost completely Dietary supplements containing only iodine are also available, and many contain high doses, sometimes above the UL [ 20 ].

Many dietary supplements that contain iodine are listed in the Dietary Supplement Label Database from the NIH [ 20 ].

This database contains label information from tens of thousands of dietary supplement products on the U. The Total Diet Study TDS , an FDA monitoring program, provides estimated iodine intakes of the U.

population [ 23 ]. Through the TDS program, foods that represent the average U. diet are purchased and analyzed for several components, including iodine. These intakes meet or exceed the EAR for all groups. TDS data do not include iodine that people obtain from the discretionary use of iodized salt [ 25 , 26 ].

Because many U. households use iodized salt, TDS data likely underestimate the true iodine intake of most U. Iodine status is typically assessed using urinary iodine measurements.

Spot urine iodine measurements are a useful indicator of iodine status within populations [ 28 , 29 ]. However, multiple hour urinary iodine or multiple spot urine measurements are more accurate for individuals [ 4 , 30 ].

Median urinary iodine concentrations, from spot samples collected as part of a large survey, can be used to characterize the iodine status of populations [ 31 ]. However, because spot samples are not a suitable indicator of individual iodine status [ 30 ], these measurements cannot be used to diagnose individual cases of iodine deficiency or to identify the proportion of a population with iodine deficiency or with excessive iodine intakes [ 31 ].

Urinary iodine measurements from NHANES have been used since to monitor the iodine status of the U. population [ 32 ]. Since the inception of the NHANES monitoring program, urinary iodine measurements have shown that the general U.

population is iodine sufficient. Much of this decline was a result of decreased levels of iodine in milk due to the reduced use of iodine-containing feed supplements and iodophor sanitizing agents in the dairy industry [ 34 ] as well as the reduced use of iodate dough conditioners by commercial bakers.

The use of erythrosine, an iodine-containing food dye commonly used in fruit-flavored breakfast cereals, also decreased during this time [ 34 ] though it is unclear to what extent this change actually affected urinary iodine levels because the bioavailability of iodine from erythrosine has been found to be low [ 35 ].
