Selenium is an essential trace mineral found in soil and water. Plants and yeast naturally convert selenium into organically bound protein forms of minerals. For improved bioavailability, Healthy Origins® SelenoExcell® contains selenium in this organically bound natural food form. SelenoExcell® was the high selenium yeast used in numerous clinical trials.
Benefits of selenium
May protect against heart disease
An analysis of 25 studies found that increasing selenium concentrations by 50% decreased heart disease risk by 24% (Flores-Mateo, 2006). Researchers believe that this is due to the anti-inflammatory effects of this mineral. Inflammation is a risk factor for coronary heart disease. And another analysis of 16 clinical trials found that selenium supplementation successfully decreased serum C-reactive protein (CRP), an inflammation marker. The same review found that this essential mineral also raised levels of a powerful antioxidant called glutathione peroxidase.
So selenium may not only lower inflammation markers but may also ease oxidative stress, which leads to cellular damage. Oxidative damage is also associated with cardiovascular disease.
Boosts immune system
But selenium’s ability to lower oxidative damage does more than just boost your heart health. Decreasing oxidative stress actually lowers inflammation and strengthens your immune system. Selenium supplementation also increases white blood cell count and enhances the function of T-cells, a specific type of white blood cell.
Prevents damage from free radicals
We already mentioned the antioxidant properties of selenium. Acting as an antioxidant, this trace mineral can balance out free radicals in the body and prevent them from causing the cellular damage associated with oxidative stress. It’s worth noting that free radicals are natural byproducts of some essential processes in your body, like metabolism. But external sources can also produce free radicals, such as pollution and cigarette smoke.
May support cognitive function
Alzheimer’s isn’t the only neurological condition with which oxidative stress is associated, though. It has also been linked to Parkinson’s and multiple sclerosis. So selenium may lessen oxidative damage and, in that way, decrease your risk of Alzheimer’s and protect your cognitive health. And patients with Alzheimer’s have been found to have low levels of selenium, as well as other nutrients such as vitamin C and vitamin E.
Important for thyroid health
Finally, we get to the thyroid gland and, by extension, your metabolism. This small but powerful part of your body has the highest concentration of selenium of all of your tissue. And the thyroid does more than regulate your metabolism through the release of thyroid hormone. This butterfly-shaped gland at the front of your neck also helps with proper growth. But low selenium has been connected with thyroid disease as well as Hashimoto’s thyroiditis, an autoimmune condition in which the body attacks the thyroid gland.
May support prostate health
A study published in 2016 found that higher blood selenium levels were associated with lower rates of several types of cancer, including lung cancer, breast cancer, and prostate cancer.
