A fairly well known nutritional supplement, selenium is present in every cell in the body. The nutrient is a naturally-occurring substance that is responsible for maintaining health within the body. With this fundamental purpose, selenium is an important nutrient that purports health and treats a wide range of conditions.
What is Selenium?
Selenium is a naturally-occurring nutrient within the body. It is most commonly found in the liver, kidneys, pancreas, spleen, and testes of males. The nutrient plays a vital role in maintaining overall health and treating various health conditions.
Selenium actually promotes the release of the enzyme glutathione peroxidase. This enzyme destroys peroxides that adversely affect essential lipids in the body. The nutrient also functions as an antioxidant that helps to eliminate free radicals in the body.
While the body does produce selenium, most individuals require some type of supplement of the nutrient. Dietary sources of the nutrient include brewer’s yeast, wheat germ, butter, garlic, sunflower seeds, walnuts, raisins, liver, shellfish, and fresh-water and salt-water fish. The nutrient is also found in a variety of grains as well as alfalfa, burdock root, fennel seed, ginseng, raspberry leaf, onion, mushrooms and other natural sources.
Health Benefits of Selenium
The main function of selenium as far as prevention is eliminating the risk of cancer. Taken in conjunction with vitamin E, selenium is particularly effective as an antioxidant.
The nutrient also functions in a variety of other ways as well. Selenium aids in reducing inflammation in the heart and other parts of the cardiovascular system, reducing the risk of heart disease, cancer, high blood pressure, and stroke. The nutrient also works to alleviate malabsorption of nutrients in the gastrointestinal tract, particularly in children. Intracranial pressure, asthma, cardiomyopathy, and dandruff also respond well to selenium treatment.
While selenium is toxic in large doses, it is an essential micronutrient for humans. It functions in the body to stimulate the production of essential enzymes that fortify and protect the body. As such, it can be used to treat a wide range of health conditions. Nonetheless, care must be taken when using the supplement to avoid adverse side effects.
Hi, Well, I recently had a urine test and blood work done. I posted a day ago that my urine test came back with very high selenium amount; over 100mcg normal value. Well, my blood work just came in and a few things are off. Maybe someone can guide me a little as I am concerned but my doc didn't seem so. The T4 and T3 were normal but I put the values incase they mean something inregards to the TSH reflex. Thanks!
TSH w/ Reflex to FT4 was 0.39 (0.40-4.50 is normal)
T4, Free was 1. 4 (0.8-1.8 is normal)
T3 uptake was 35 (22-35% is normal)
Alkaline Phosphate was 38 (Low) (40-115 is normal)
Albumin/Globulin ratio was 2. 2 (high) (1.0 - 2.1 is normal)

Well I had a 24 hr urine test done for heavy metals and in this included selenium. Well everything came back normal except my selenium The normal range is 150-250 and I was 355. My doctor was shocked and could not find I reason as to why.
I do take selenium supplements but I just started them several days before, besides that there is not much else of selenium in my diet.
I read there could be a connection between high selenium and diabetes but I have a well controlled diet and my fasting glucose was 86 and A1C was well within the normal range.
The other thing I read was that Selenium and thyroid work together... Something along those lines. I just couldn't understand if I would be hypothyroid or hyper in relation to selenium being high.
Any info would be helpful, thanks!Replied by Timh
