JustYourTypeDTP wrote: Just what DOES Selenium do again?:)Sue Selenium for thyroid health German researchers have found that supplementing with selenium may slow the progression of autoimmune thyroid disease (AITD), and may be most effective at the onset of

thyroiditis. AITD refers to a number of different disorders in which the immune system attacks the cells of the thyroid gland, causing symptoms of thyroid disease. AITDs include both disorders of hypothyroidism—reduced thyroid hormone production—and hyperthyroidism—excess thyroid hormone production. Researchers believe that a deficiency in selenium may contribute to the development of AITD because selenium has a direct impact on immune system enzymes. Dr. Barbara Gasnier, MD, of the Medizinische Klinik University, Munich, Germany, led a study that consisted of 72 women with a mean age of 47. All had AITD, and all had thyroid peroxidase (TPO) antibodies greater than 350 units per milliliter of blood. TPO antibodies are not present in healthy individuals. Half the participants received 200 mcg of selenium per day for three months, while the other half received a

placebo. All patients were normalized on their thyroid hormone treatment. TPO antibody levels were measured at the conclusion of the three-month study period. Nine of the patients taking selenium had TPO antibody levels return to normal. By contrast, only two members of the placebo control group had TPO antibody levels return to normal. In the selenium group, the TPO antibody levels had a mean decrease of 40%, compared to a 10% increase in the placebo group. The higher the TPO antibody levels at the onset of the test, the greater the reduction at the end of the three-month study period. The researchers concluded that selenium supplementation may reduce thyroid inflammation in patients with AITD. Reference: The Journal of Clinical Endocrinology & Metabolism; Vol. 87, No. 4, 1687-91.

JustYourTypeDTP wrote: Just what DOES Selenium do again?:)Sue What Are Selenium's Benefits? Protection Against Certain Types Of Cancer. People with higher blood concentrations of selenium are

thought to have a lessened chance of acquiring prostate, lung, co-rectal or skin cancers.2 In population studies, people in selenium deficient areas have been shown to have higher rates of these cancers compared to the general population, thus strengthening the link between optimum selenium status and free-radical counteraction. Some researchers, on the other hand, believe selenium may work by improving the body's natural immune response against cancer cells and suppressing development of blood vessels to the tumour. Good news for men: a recent study found that men who had the highest blood concentrations of selenium, cut their chances of getting prostate cancer by one-half to two-thirds, compared to men with lower levels. In one of the most famous selenium studies, researchers found, upon analysing toe clippings (an accurate analytical tool for assessing nutrient status), men who had higher levels of selenium, developed 65% fewer cases of advanced

prostate cancer.10 Earlier cancer studies found cancer patients with low levels of selenium, developed more subsequent tumours. Survival rates for cancer patients with low selenium levels were generally shown to be shorter. Enhancing Of Immune function.5,6 Selenium's immune boosting properties are thought to stem from its ability to strengthen phagocytes (white blood cells that attack invading toxins). It has been shown, also, that selenium enhances the capacity of lymphocytes, to proliferate, and differentiate into cytotoxic effector cells, which kill antibody-coated target cells.3 This same study demonstrated that the molecular mechanism mediating selenium's effect on immunity is not linked to the function of selenium as an antioxidant, thus highlighting its separate immune bolstering role. Protection Against Heart Disease. Serious heart defects in large animals (cattle etc) have been attributed to selenium deficiency. An abnormally low concentration of coenzyme Q10 (a substance essential for healthy heart functioning) in animals with heart defects, is thought to be linked to a deficiency in selenium and vitamin-E (a vitamin that teams with selenium to boost the immune system, and fight disease)9 - both selenium and vitamin-E are needed to maintain adequate coenzyme Q10. Additional lines of evidence suggest oxidative stress created by free-radicals, as a result of selenium deficiency, promote heart disease.7,10 Oxidised LDL cholesterol plays major role in heart disease due to its propensity to contribute to plaque formation, and selenium is thought to

limit this oxidation. Selenium may even increase the proportion of beneficial HDL cholesterol to the problematic LDL. Protection Against Arthritis. Sufferers of arthritis have been found to have reduced selenium levels in their blood. Arthritis, a chronic disease that causes pain, stiffness, swelling, and loss of function in joints, often results from excessive free-radicals made by the immune system in response to invading organisms.10 Thus, controlling free-radicals with the help of selenium might relieve the symptoms of arthritis. Prevention Of Cataracts. Studies have found that eye lenses that are affected by cataracts have about one-sixth of the normal amount of selenium.10,11 As a result, researchers believe a

selenium deficiency might be a contributory factor in cataract formation. Cataracts A cataract is a clouding of the natural lens, the part of the eye responsible for focusing light and producing clear, sharp images. The lens is contained in a sealed bag or capsule. As old cells die they become trapped within the capsule. Over time, the cells accumulate causing the lens to cloud, making images look blurred or fuzzy. For most people,

cataracts are a natural result of aging. In fact, they are the leading cause of visual loss among adults 55 and older. Eye injuries, certain medications, and diseases such as diabetes and alcoholism have also been known to cause cataracts. Once again, it is selenium's antioxidant function, which fights the free-radical build-up, that negates damage to the eye's lens (the site of cataracts) and the macula at the centre of the eye's retina.10 In the latter case, selenium is also shown to prevent macula degeneration. Detoxification Of Poisons. Toxic metals such as arsenic,

mercury, and cadmium undergo a reduction in toxicity when they bind with selenium.8 Shampoos, and various topical medications, have added to them, selenium to offset their toxic effect. Protection Of Genetic Materials. Selenium helps to prevent cellular DNA damage resulting from free-radical build-up. Enhance Psychological Well-Being. Low levels of selenium have been linked to cognitive decline in the elderly, as well as, confusion, depression, fatigue and anxiety in the adult general population.9 A 2004 finding indicated selenium might positively effect mood, behaviour and cognitive function due to the significant role it plays in thyroid regulation.1,6 It was suggested that patients who have a

combination of hypothyroidism, depression and increased susceptibility to viral infections, could be deficient in selenium. AIDS Management. Many vital nutrients are depleted from the body as a result of the damage incurred by AIDS, and selenium is the one micro-nutrient most commonly associated with AIDS, so much so, it has been linked closely to a high risk of death from this disease. Retroviruses. like HIV/AIDS, cause the depression of selenium by encoding the gene for the human selonoprotein glutathione peroxidase.10 As mentioned, glutathione peroxidase is the antioxidant enzyme form of selenium, and if its gene is encoded, in response to retroviral attack, the virus will replicate indefinitely by continually depriving the body of glutathione. Opportunistic pathogens will then invade the immune system to further deplete the

body of selenium, which compromises the immune system further, and hastens AIDS related death. Prevention Of Fertility Problems. Selenium deficiency has been linked to sperm abnormalities and increased risk of early pregnancy loss.11, 12 In fact, healthy sperm formation is dependant, to a large extent, on selenium intake - blood levels of selenium are found to be lower in men with low sperm counts.12 sufficient blood levels of selenium also have been shown to help prevent chromosome breakage, which is known to be a leading cause of birth defects and miscarriages.

OK so theoretically I would need to or be able to, take less direct T3 if this does kick in?

I guess I will know when I see the blood work, only I don’t for for 8 weeks and I take t4 and t3...

Sue

In thyroid terms, Selenium is used in the conversion of T4 to T3 (for one thing).

Helps with mental clarity, and beyond that I can't remember......LOL Obviously I'm low on it. Somebody posted a human version of what selenium can do, can you post that again?

hi-

I'm wondering if it is important to supplement extra selenium with rT3 issues?

(i get the RDA in my multi, but i'm wondering if i should supplement extra)

thanks much! tammy

IF on T-3 only, no. To quote Val: " I do not feel iodine or selenium are needed

while on T3 "

from her post:

http://health.groups.yahoo.com/group/RT3_T3/message/27212

IF on a med containing T-4, see Val's post:
