What is Selenium?

Benefits of Selenium

Potent Antioxidant: Selenium functions as an antioxidant by collaborating with other antioxidants, including vitamin E, to shield cells against oxidative stress brought on by free radicals. It aids in disarming dangerous chemicals that might trigger chronic illnesses, including cancer, heart disease, and age-related degenerative disorders.

Support for the Immune System: Selenium is essential for a healthy immune system. Cytokines are necessary for immune cell communication and are produced with its assistance. It supports immune cell health, particularly T cells and natural killer cells. Adequate selenium levels may improve immunological responses, aiding the body’s ability to more successfully fight off diseases and infections.

Thyroid Health: Selenium is necessary for synthesizing and activating thyroid hormones, which impacts thyroid health. It facilitates the transformation of the dormant thyroid hormone T4 (thyroxine) into the active form, T3 (triiodothyronine). A healthy thyroid, which controls metabolism, energy generation, and growth and development, benefits from optimal selenium levels.

Mental Health: It may lower the risk of cognitive decline and neurodegenerative diseases like Alzheimer’s. It stimulates the neurotransmitters’ synthesis in mood control and protects brain cells from oxidative damage.

Male and female reproductive health: Selenium is crucial to good reproductive health. It is necessary for guys to create healthy sperm and aids in preserving maximum fertility. Selenium helps females’ ovaries function optimally and may lower their chances of difficulties during pregnancy.

What are the Symptoms of Selenium Deficiency?

Selenium insufficiency is relatively uncommon in well-fed people who consume a balanced diet. Deficiency, however, may happen in regions with low soil selenium levels or in people with certain medical disorders that worsen absorption or increase excretion. The following are some typical signs of selenium deficiency:

Weak Immune System: Selenium shortage may affect how well the immune system functions, making people more prone to infections and disorders. Common colds, the flu, or other illnesses might indicate a compromised immune system.

Weakness and Exhaustion: Because selenium is involved in energy metabolism, a shortage may cause muscle weakness, low energy levels, and fatigue.

Cognitive Decline: Low selenium consumption has been linked to mental problems such as forgetfulness, lack of attention, and slow thought processes.

Thyroid dysfunction, which includes weight gain or trouble reducing weight, sluggishness, dry skin, and mood swings, may be brought on by inadequate selenium levels.

Selenium deficiency may cause muscular weakness, stiffness, and aching joints, among other muscle and joint pain symptoms.

Changes to Hair and Nails: Selenium helps to keep Hair and Nails Healthy. Hair loss, brittle hair, and weak, easily broken nails may all result from deficiency.

Selenium deficiency in men may decrease the quality and fertility of sperm. It may have a role in female infertility and irregular menstrual cycles.

Remembering that these symptoms could be connected to other underlying medical issues is essential. Speaking with a healthcare provider is advised if you think you may be deficient in selenium. They can do the necessary tests to confirm the condition and provide helpful treatment advice.
