According to a new Canadian review, supplementation with high-dose antioxidant vitamins and trace elements may reduce mortality risk of patients with greater severity of illness, particularly those at high risk of death.
This systematic review and meta-analysis included 21 randomized controlled trials evaluating the potential effects of antioxidant vitamin and trace element therapy on the overall mortality risk of critically ill adult patients (1). The analysis showed that high-dose antioxidant supplementation was associated with a significant reduction in mortality. In addition, the data showed a trend towards a reduction in infectious complications and a significant decrease of the duration of mechanical ventilation in the patients.
The researchers concluded that antioxidant supplementation in the critically ill may be able to significantly reduce overall mortality. As critical illness is characterized by oxidative stress with antioxidant depletion, supplementation of antioxidant micronutrients, such as vitamins C and E and selenium, could restore antioxidant status, thus improving survival rate. The treatment’s effects may be greatest in patients with greater severity of illness and may depend on the type of intervention and/or the method of antioxidant administration. In the last two decades, several clinical trials have evaluated the role of antioxidant micronutrients as a monotherapy or as part of an antioxidant strategy for critically ill patients in combined therapy. According to the scientists, further researchers are warranted to define the optimal combination, optimal dose and timing of supplementing antioxidant micronutrients.

There has been more written and published over the efficacy of vitamin D than over that of most nutrients. Dozens of randomized, controlled trials have been conducted – some large, many small. Unfortunately, the results of many studies have been inconsistent – some positive, some null, and one or two actually negative.

Sexual health is of particular importance to a man: not only when he wants to start a family, but during all phases of his life. And while sexuality’s functions differ from man to man, in almost all societies there is a connection between a man’s success and his sexual health. This applies to most aspects of a man’s life as his body’s functionality and performance must be just as good sexually as it is in his working life and in sports. Hence, sexual health affects a man’s quality of life and his self-esteem. A balanced, micronutrient-rich diet plays an important part in maintaining sexual and reproductive health.
