More nutrients that support thyroid health...we need these along WITH our iodine, folks! Personally, since beginning supplemetation of 200 mcg. selenium per day, my sleep patterns have normalized..and, from Vulcanel:

"Awesome. Selenium is definitely necessary, to protect the thyroid from peroxide-induced necrosis. I chew some yeast tablets that are spec'd to have 200 mics of selenium each."

Now, I'm not sure what peroxide-induced necrosis is, but I'm quite sure that I don't want to find out! Perhaps one of the more scientifically-inclined here could illuminate us on that point?

TAKE YOUR SELENIUM, PEOPLE!!!! MUCHO IMPORTANTE!!!

for your consideration, people:

Hair Trace Elements and Hypothyroidism - March 00

David L.Watts, Ph.D., Director of Research
Occurrence of Hypothyroidism
It has been estimated by Barnes, et al, that 40 percent of the American population suffers from hypothyroidism and is the most common complaint seen by doctors in their county.1 This estimation was made over 25 years ago and if we include subclinical hypothyroidism we can conservatively raise this estimation to over 50 percent. Severe clinical hypothyroidism is readily evident from blood test, however subclinical thyroid insufficiency is not easily detected through normal test. I have described subclinical hypothyroidism as a syndrome rather than a disease and is characterized by fatigue, depression, cold sensitivity weight gain and changes in the texture of the hair and skin.

Thyroid insufficiency affects females at a greater frequency that males. From our database of over 2000 patients submitted with hypothyroidism predominate symptoms, 90 percent were females. The reason for this gender difference ahs been discussed elsewhere and will not be reviewed here.2

Nutrition and the Thyroid

Iodine
There are a number of nutrients that affect the thyroid. The most recognised being iodine. Iodine deficiency is associated with endemic colloid goiter a condition that occurred in areas of low Iodine soils prior to its prevention with the introduction of iodized salt. Idiopathic nontoxic goiter is identical to endemic goiter but is not associated with iodine. In fact, iodides can actually reduce all thyroid gland activities by inhibiting thyrotropin possibly by inhibiting the hypothalamus. Reduced thyroid activity is often seen even in the presence of normal Iodine levels.3,4 A great deal of emphasis is placed upon iodine in assessing thyroid status, but there are many other factors that are important.

Iron and Vitamin A
Iron and vitamin A deficiencies are prevalent in areas of endemic goiter, although, iodine intake in adequate. It is now recognized that the response to iodine therapy is ineffective in the presence of iron deficiency. Iron is required for the conversion of L-phenylalanine to L-tyrosine and may be reduced by over 50 percent with iron deficiency. Many patients with hypothyroidism respond favourably to vitamin A therapy.5

Selenium, Zinc and Chromium
Selenium deficiency can contribute to hypothyroidism due to its involvement in the conversion of T4 to active T3. Selenium is a constituent of the enzyme 1 iodothyronine deiodinase (IDI) an enzyme responsible for the peripheral conversion of T4 to T3 in the liver and kidneys, This enzyme is markedly reduced in selenium deficiency.6
Zinc influences the secretion of thyroid stimulating hormone (TSH). Therefore, zinc deficiency or a low zinc to copper (Zn/Cu) ratio can be involved in lowered thyroid expression.
A number of research studies have found an interaction between chromium and thyroid activity. The mechanism is not yet understood, however this association may be explained through tissue mineral analysis (TMA) patterns.7

Thyroid Antagonists
Nutritional
Goitrogens are naturally occurring anti-thyroid substances found in foods that adversely affect the thyroid. These are commonly known foods and therefore will not be discussed here. Other nutritional factors known to inhibit thyroid function include:

Elevation of the Ca/Mg ratio indicates a relative increase in parathyroid hormone as well as insulin productions. A reduced Zn/Cu ration indicates a reduction in progesterone relative to estrogen in the female. The relationship of chromiom and thyroid activity could be explained by chromuin’s effect upon insulin sensitivity. Reducing insulin levels would result in improved thyroid hormone activity. The increased cellular immune response common in the Slow Metabolic type could contribute to thyroid disorders due to an autoimmune response.
The greater the numbers of the above mineral ratios present in a TMA profile, the stronger that tendency toward reduced thyroid expression, It should also be noted that these ratios would be reversed in hyperthyroid conditions.
Psychophysiology of Thyroid Disorders Brain Hypothyroidism
The relationship between thyroid dysfunction and psychiatric disorders has been recognized for over a century and described in cases of myxedema and cretinism. Depression is one of the major symptoms accompanying hypothyroidism. However, other conditions associated with hypothyroidism accompanying mood disorders include:8
Fatigue Constipation
Excessive Sleep Pattern Loss of Appetite
Weight Gain Poor Memory
Decreased Sex Drive Reduced Interest
Poor Concentration
Reduced Sense of Pleasure
Fatigue is the most common physical symptom associated with Depression and results from a diminished thyroid function. The basal metabolic rate of a person with hypothyroidism can be reduced as much as 40-50 percent below normal. It is therefore not difficult to understand the relationship between thyroid status and the health energy continuum.

The thyroid has a significant role in regulating central nervous system (CNS) development and function, and is known to affect cerebral metabolism in adults. Thyroid hormones regulate brain functions via its interaction with the catecholaminergic system and affects synaptic levels of norepinephrine uptake and its receptors. In most patients suffering from depression, the serum levels of TSH, T4 and T3 are within the normal range. However, even with a normal systemic thyroid status, a patient may actually be suffering from "Brain Hypothyroidism".10,11 Reduced cerebral thyroid expression could therefore, contribute to a host of psychological symptoms. This would explain why many patients with psychiatric conditions respond well to thyroid support, since there are extensive T3 receptors in the brain. The effectiveness of serotonin reuptake inhibitors (SSRI such as Prozac® may be effective in some patients due to the drug’s effect of increasing the availability of T3 in the brain. Conversely, thyroid hormone increased the brain content of serotonin.8

Conclusion
Meng stated that "In the majority of cases, the symptoms of hypothyroidism develop slowly and as a result, they often are not recognized or are misjudged for a long time. In the case of subclinical hypothyroidism, an indication for treatment does not exist in all patients. In cases of doubt, therapy can be initiated and discontinued after 6-12 months when there is not therapeutic effect."12
Early treatment of patients with physical and psychological symptoms of hypothyroidism may help in preventing progression to an overt hyperthyroid condition. TMA can provide insight to individual thyroid status and aid in modifying diet and nutritional intake to prevent the long-term and chronic condition associated with hypothyroidism. Therapy can aid not only in Depression but in other thyroid related conditions as well, including, musculoskeletal disorders, fibromyalgis, chronic fatigue, cardiovascular disorder,13,14 diabetes15,16 and conditions associated with autoimmune responses.
