Numerous studies have explored the relationship between selenium levels and overall health, observing an association between adequate selenium intake and support for the body’s natural defenses. While laboratory research has investigated selenium’s role in cellular health, it’s important to approach these findings with the understanding that dietary supplements are intended to support overall well-being and not to diagnose, treat, cure, or prevent any diseases. Selenium is recognized for its contribution to antioxidant processes and supporting the body in maintaining normal function.
Epidemiological studies suggest a connection between antioxidant status and cardiovascular health, highlighting the importance of antioxidants in supporting the body’s defense against oxidative stress. Selenium, recognized for its antioxidant properties, may contribute to the body’s efforts to maintain healthy levels of LDL by supporting antioxidant defense systems. Including selenium as part of a balanced diet is one way to support overall health and well-being.
Selenium and antioxidant activity
The National Academy of Sciences (NAS) published a report on April 11th that explores the evolving understanding of antioxidants and their potential to support overall health. The Council for Responsible Nutrition acknowledges that, although current scientific evidence does not support specific intake recommendations for antioxidants based on disease prevention, there is consensus on a broad range of safe intakes for antioxidant vitamins. This acknowledgment highlights the importance of including antioxidants as part of a balanced diet to support general wellness. It issued higher recommended dietary allowances (RDAs) for vitamins C and E. The new RDAs for antioxidant nutrients are: vitamin C (75 milligrams (mg) for women and 90 mg for men), vitamin E (15 mg), and selenium (55 micrograms (μg))
The report stated that there is “reason to expect that the antioxidant vitamins (C and E) should decrease the risk of cardiovascular disease.” The report concluded that vitamin E does inhibit LDL oxidation (a causative agent for cardiovascular disease) and could also affect the health of arteries in other ways. The report also noted that it is reasonable to expect that vitamin C would reduce oxidative damage to the eye, thus lessening the risk of cataracts and other conditions
The NAS report also established tolerable upper intake levels (ULs) for vitamin C (2,000 mg), vitamin E (1,000 mg) and selenium (400 μg). ULs for adults are set to protect the most sensitive individuals of the general population
Selenium and healthy blood sugar levels
Selenium is reported to mimic the action of insulin. In the laboratory studies performed in recent years, selenium has been shown to mediate a number of insulin-like actions such as stimulating glucose uptake and regulating metabolic processes including glycolysis, gluconeogenesis, fatty acid synthesis, and the pentose phosphate pathway. Research indicates that selenium may support the body’s metabolic processes in ways that are not fully understood, including involvement in the activation of proteins that play a role in normal insulin signaling. Additionally, selenium’s antioxidant properties are recognized for their potential to support the body in managing oxidative stress, which is a concern for overall health. This support may contribute to the body’s overall well-being, including the health of nerves, eyes, and other systems, by supporting the body’s natural defense mechanisms against oxidative stress.
Studies have observed an association between selenium levels and joint health, suggesting that adequate selenium intake may support joint comfort and mobility. Selenium’s antioxidant properties, recognized for their potential to protect against oxidative stress, may contribute to the overall maintenance of healthy joints. While research is ongoing, incorporating selenium as part of a balanced diet emphasizes its role in supporting the body’s natural defenses and promoting general well-being
Selenium Support in Overall Health and Immune Function
Nutritional support is an important consideration in the overall care of individuals with chronic health conditions. A study observed 24 children with HIV over a five-year period, noting an association between selenium levels and overall health outcomes. This research underscores the significance of monitoring nutritional status as part of comprehensive health management. Ensuring adequate selenium intake, as part of a balanced diet, may play a role in supporting the body’s general well-being and resilience
Selenium and CNS
Research suggests an association between selenium levels and cognitive health, highlighting the importance of adequate selenium intake for maintaining cognitive function and overall well-being. Observational studies have noted the potential of selenium in supporting mood and mental clarity, contributing to a reduction in feelings of fatigue and anxiety. While findings on selenium’s support for cognitive health and well-being are promising, further research is needed to fully understand its role. Including selenium as part of a balanced diet emphasizes its contribution to supporting the body’s natural processes and maintaining overall health
