8 Selenium Health Benefits You Should Be Aware Of

What Is Selenium

Selenium is a vital mineral that is primarily obtained through your eating plan. You only need it in small amounts, however, it plays a significant role in essential bodily processes, including thyroid function and a healthy metabolism.  It is essentially a mineral found in soil, but it also naturally occurs in water and certain foods. The mineral has attracted attention due to its antioxidant properties. It impacts various important processes in the body, including:

  • Protection against infections
  • DNA synthesis
  • Reproduction
  • Thyroid hormone metabolism

8 Selenium Health Benefits

Some of the health benefits of selenium include:

  1. Acting As A Potent Antioxidant

Free radicals are standard byproducts of processes formed in the body on a daily basis, including metabolism. They often have a negative connotation to them, but free radicals are vital for your health. They have necessary functions like protecting your body against disease. However, things like alcohol, smoking, and stress can result in an excess of free radicals which subsequently causes oxidative stress that damages healthy cells in the body.

Oxidative stress is associated with chronic conditions like Alzheimer’s, heart disease, premature aging, cancer, and a higher risk of stroke. Selenium can help lower oxidative stress by avoiding an excess of free radicals in the body. They operate by protecting cells from damage and keeping free radical numbers in check.

  1. Lowering The Risk of Certain Cancers

Amplified blood levels of selenium can lower the risk of certain cancers, and supplementing with this mineral can help enhance the quality of life of those that undergo radiation therapy.

  1. Assisting in Prevention of Mental Decline

Alzheimer’s disease is a life-changing condition that leads to memory loss and adversely affects behaviour and thinking. It is the sixth-leading cause of fatalities in the US, and the numbers keep growing. Thus, finding ways to prevent this devastating disease is imperative. An eating plan rich in selenium can help with mental decline prevention and enhance memory loss in those with Alzheimer’s disease.


  1. Heart-Friendly

A selenium-rich diet can help with heart health, lowering the risk of heart disease. It can help by keeping oxidative stress at bay which is one of the risk factors for heart disease.

  1. Boosting Fertility

Many think of selenium as a “super” vitamin for boosting fertility because of its antioxidant properties. Selenium assists with promoting healthy uterine follicles, where eggs are formed and released. The recommended dose for women who are trying to conceive is 60 mcg daily. It is also beneficial for men.

  1. Thyroid Health-Booster

Selenium is an essential element of a proper functioning thyroid gland. Your thyroid tissue has a higher selenium content than any other body part. This potent mineral assists with protecting the thyroid against oxidative damage and also helps in producing thyroid hormones. Having a healthy functioning thyroid gland is essential for regulating your metabolism and controlling development and growth. Selenium deficiency has been linked to thyroid conditions such as Hashimoto’s thyroiditis – where the immune system attacks your thyroid gland.

  1. Boosting Your Immune

The immune system is quintessential for identifying and combating potential health treats like viruses, bacteria, and parasites. Selenium assists with lowering oxidative stress in the body, which lowers inflammation, and boosts immunity.

  1. Lowering Asthma Symptoms

Asthma is a chronic condition that impacts the airways and transport air into and out of the lungs. These airways get inflamed and start to narrow, leading to symptoms  like shortness of breath, coughing, wheezing, and chest tightness. The condition has been linked to excess levels of inflammation and oxidative stress in the body. Because selenium reduces inflammation and keeps oxidative levels in check, it goes a long way in reducing asthma symptoms.
