The Facts:
* A small but well designed study was undertaken to explore whether the levels of zinc in men affected their performance during exercise.
* Study volunteers were given a specific diet and some supplemented with zinc.
* Testing their blood and exercise tolerance showed those with low zinc intake had lower levels of zinc concentration and retention and also reduced exercise performance.
Shaun’s comment: Zinc has been used by people for dozens of purposes, with mines operating since around 1200 BC. In terms of human health, zinc is an essential element, and life is not possible without it. Dietary sources include meat, beans, nuts and grains and the recommended intake is around 10 mg each day for adults. This study looked at whether zinc helped exercise performance, on the basis that zinc is present in many of the enzymes involved in the functioning of red blood cells and heart and lung function. It was a small study, but the results suggest that zinc does in fact help.
