Selenium and Its Importance for Human Health
Health Benefits of Selenium
- Antioxidant Defense: Selenium is a key component of enzymes like glutathione peroxidase, which protect cells from oxidative damage.
- Thyroid Health: Supports the production and regulation of thyroid hormones, aiding in metabolism and overall endocrine health.
- Immune Function: Enhances the immune system by supporting the function of white blood cells.
- Heart Health: Helps reduce inflammation and may lower the risk of heart disease by protecting blood vessels from oxidative stress.
- Cognitive Function: May contribute to brain health and reduce the risk of cognitive decline.
Interactions with Other Minerals and Vitamins
Interactions with Other Minerals
- Iodine: Selenium works synergistically with iodine to support thyroid hormone production and conversion to its active form, aiding in thyroid health.
- Zinc: Selenium and zinc together support immune health and antioxidant defenses, helping maintain a balanced response to oxidative stress.
- Copper: Both selenium and copper play roles in antioxidant protection, with copper supporting enzymes like superoxide dismutase.
Interactions with Vitamins
- Vitamin E: Selenium enhances the antioxidant effect of vitamin E, working together to protect cells from free radical damage.
- Vitamin C: Supports overall antioxidant function and may enhance the protective properties of selenium.
- Vitamin A: Helps in maintaining overall immune health, and selenium assists in the proper utilization of vitamin A for cellular protection.
