7 Surprising Health Benefits of Selenium Backed by Science

7 Science-Based Health Benefits of Selenium

Selenium Overview

Selenium is a trace element that is essential for human health. It is found in soil, water, and certain foods. Our bodies only require small amounts of selenium, but it plays a crucial role in several important bodily functions.

The 7 Health Benefits of Selenium

1. Antioxidant Properties

1. Antioxidant Properties

Selenium is a powerful antioxidant that helps protect our cells from damage caused by free radicals. Free radicals are molecules that can lead to oxidative stress, which is associated with various chronic diseases, including cancer and heart disease.

2. Boosts Immune System

Selenium plays a vital role in maintaining a healthy immune system. It helps regulate the activity of certain immune cells and supports the production of antibodies, our body’s defense against foreign invaders like bacteria and viruses.

3. Supports Thyroid Function

Selenium is an essential nutrient for proper thyroid function. It helps convert the inactive thyroid hormone (T4) into its active form (T3), which is necessary for metabolism regulation, energy production, and overall thyroid health.

4. May Reduce the Risk of Certain Cancers

Several studies have shown that selenium may help reduce the risk of certain types of cancers, including prostate, lung, colorectal, and bladder cancers. It acts as an antioxidant and also supports DNA repair, which can help prevent the development of cancer cells.

5. Improves Male Fertility

Selenium has been linked to improved male fertility. It helps maintain sperm quality and motility and protects sperm cells from oxidative damage. Adequate selenium levels may also enhance male reproductive health and increase the chances of successful conception.

6. Protects Heart Health

6. Protects Heart Health

Selenium plays a critical role in maintaining heart health. It helps reduce inflammation, regulate blood pressure, prevent the oxidation of bad cholesterol, and improve overall cardiovascular function. These benefits contribute to a decreased risk of heart disease and stroke.

7. Enhances Cognitive Function

7. Enhances Cognitive Function

Selenium is involved in various processes that support healthy brain function. It helps protect brain cells from oxidative stress, reduces inflammation in the brain, and supports the production of vital brain chemicals. Adequate selenium levels may contribute to improved memory, attention, and overall cognitive function.

While selenium is important for our health, it’s important to note that too much selenium can be toxic. It’s essential to consume selenium within the recommended daily intake guidelines or as advised by a healthcare professional.

In conclusion, selenium offers numerous health benefits, including its antioxidant properties, immune-boosting effects, support for thyroid function, potential cancer risk reduction, improvement of male fertility, protection of heart health, and enhancement of cognitive function. Incorporating selenium-rich foods into your diet or considering supplementation could help you reap these health benefits.
