Creatine is an ergogen for anaerobic exercise

Article Abstract:

Creatine can be a useful erogenic dietary supplement for some athletes, although several health issues should be addressed. The effects of long-term use are unknown and further controlled toxicology studies are necessary. Users should be wary of product impurities. Large intakes may cause elevated serum creatinine concentrations. Although it will not enhance aerobic exercise or endurance performance, creatine supplementation may prove helpful for high-intensity strength athletics and anaerobic exercise. Research is also needed on the use of creatine supplementation in treating muscle weakness and for maintaining pre-transplant cardiac tissue.

Iron, anemia, and infection

Article Abstract:

The relationship between iron deficiency and infection is controversial. Iron supplementation has been linked to a worsening of some diseases, including tuberculosis, kwashiorkor, malaria and brucellosis. However, other studies have found that iron supplementation lowers the risk for some diseases, including iron deficiency anemia, respiratory infections, meningitis and pneumonia. There is no evidence that food fortification with iron increases the risk of infection.
