Top 6 Major Selenium Benefits

1. Protect Against Heart Disease

Low selenium levels have been linked to an increased risk of heart disease; therefore, a selenium-rich diet may help keep your heart healthy.

A 50% rise in blood selenium levels was related to a 24% reduction in the incidence of heart disease in a meta-analysis of 25 observational studies.

The first on the list of Selenium benefits is that it boosts glutathione peroxidase levels, a strong antioxidant. This suggests that selenium may help decrease your risk of heart disease by lowering inflammation and oxidative stress in your body. Atherosclerosis, or the development of plaque in arteries, has been related to oxidative stress and inflammation.


2. May Help Reduce Asthma Symptoms

Next on the list of selenium benefits is that it can help you ease asthma symptoms. Asthma is a chronic illness that affects the airways that transport oxygen and carbon dioxide into and out of the lungs. These airways become inflamed and constricted, resulting in symptoms such as wheezing, shortness of breath, chest tightness, and coughing.

Asthma has been linked to increased oxidative stress and inflammation in the body. Some studies show that selenium may help lessen asthma-related symptoms due to its ability to reduce inflammation. One study found that asthmatic individuals with greater blood selenium levels had better lung function than those with lower levels.

Selenium supplements may also aid in the reduction of asthma symptoms. According to one research, treating patients with asthma 200 mcg of selenium per day lowered their need for corticosteroid medicines to regulate their symptoms.


3. Reduce Your Risk of Certain Cancers

Selenium, in addition to reducing oxidative stress, may also reduce the incidence of some malignancies.

This is due to selenium’s ability to decrease DNA damage and oxidative stress, strengthen your immune system, and kill cancer cells.

A meta-analysis of 69 studies including over 350,000 people discovered that having a high blood selenium level was related to a decreased risk of several forms of cancer, including breast, lung, colon, and prostate cancer.


4. Helps Prevent Mental Decline

Several studies have found that people with Alzheimer’s disease had decreased blood levels of selenium.

Furthermore, several studies have indicated that antioxidants in both meals and supplements may enhance cognition in Alzheimer’s patients. Oxidative stress is thought to play a role in the beginning and progression of neurological disorders such as Parkinson’s, multiple sclerosis, and Alzheimer’s.

Additionally, the Mediterranean diet, rich in high-selenium foods including fish and nuts, has been linked to a decreased risk of Alzheimer’s disease.


5. Boosts Your Immune System

Your immune system protects your body by detecting and combating possible threats such as bacteria, viruses, and parasites.

Another of Selenium benefits is that it is essential for the health of your immune system. This antioxidant aids in the reduction of oxidative stress in the body, which lowers inflammation and improves immunity.

Increased selenium levels in the blood have been linked to improved immunological response in studies. Deficiency has also been linked to an increased risk of mortality and illness progression in HIV patients. In contrast, supplements have been found to lead to fewer hospitalizations and improved symptoms in these individuals.


6. Crucial for Thyroid Health

Last on the list of Selenium benefits is its critical role in maintaining thyroid function. Thyroid tissue, in fact, contains more selenium than any other organ in the human body.

This potent mineral protects the thyroid from oxidative damage and is required for the synthesis of thyroid hormones. A functioning thyroid gland is essential since it affects your metabolism as well as growth and development.

Furthermore, some research suggests that taking selenium supplements may help patients with Hashimoto’s disease.

According to one study, taking selenium pills on a regular basis for three months resulted in fewer thyroid antibodies. It also improved mood and general well-being in those with Hashimoto’s illness.

Selenium is a powerful mineral that is crucial for your body to function correctly. It is essential for metabolism and thyroid function, as well as for protecting your body from the effects of oxidative stress. Furthermore, selenium may help strengthen your immune system, decrease age-related mental decline, and potentially lower your risk of heart disease.
