🍽️ Selenomethionine {Selenium supplement}

Antioxidant Protection: Selenium acts as a cofactor for glutathione peroxidase, an antioxidant enzyme that helps neutralize reactive oxygen species (free radicals) and protect cells from oxidative damage. Adequate selenium intake is important for maintaining cellular integrity and reducing the risk of oxidative stress-related diseases such as cardiovascular disease, cancer, and neurodegenerative disorders.

Thyroid Function: Selenium is essential for the synthesis and metabolism of thyroid hormones. It is a component of selenoproteins such as iodothyronine deiodinases, which are enzymes involved in the conversion of thyroxine (T4) to triiodothyronine (T3), the active form of thyroid hormone. Selenium deficiency can impair thyroid function and contribute to thyroid disorders such as hypothyroidism and goiter.

Immune Function: Selenium plays a role in modulating immune responses and supporting immune function. It helps regulate inflammatory processes, cytokine production, and lymphocyte proliferation. Selenium deficiency has been associated with impaired immune function and increased susceptibility to infections and inflammatory conditions.

Cancer Prevention: Selenium has been studied for its potential role in cancer prevention and treatment. It possesses antioxidant properties and may help protect against DNA damage and inhibit tumor growth and progression. Some research suggests that selenium supplementation may reduce the risk of certain cancers, particularly prostate, colorectal, and lung cancer, although results have been mixed and further studies are needed to clarify its effects.

Cardiovascular Health: Selenium may have beneficial effects on cardiovascular health, primarily through its antioxidant and anti-inflammatory properties. It helps protect against oxidative damage to blood vessels and lipid peroxidation, which are implicated in the development of atherosclerosis and cardiovascular disease. Selenium supplementation has been associated with improved endothelial function, reduced inflammation, and decreased risk of cardiovascular events.

Male Fertility: Selenium is important for male reproductive health and sperm function. It is a component of selenoproteins involved in sperm maturation, motility, and viability. Selenium deficiency has been associated with impaired sperm quality and male infertility. Supplementation with selenium may help improve sperm parameters and fertility outcomes in men with suboptimal selenium status.

Mood Disorders: Selenium has been implicated in mood regulation and mental health. It plays a role in the synthesis and metabolism of neurotransmitters such as serotonin and dopamine, which are involved in mood regulation. Some studies suggest that selenium deficiency may be associated with an increased risk of depression, anxiety, and other mood disorders. However, more research is needed to determine the relationship between selenium status and mental health outcomes.

Hair and Nail Health: Selenium may play a role in maintaining healthy hair and nails. It is involved in the synthesis of proteins such as keratin, which are essential for hair and nail structure and strength. Selenium deficiency has been associated with brittle hair and nails, and supplementation may help improve their condition.
