The IOC has released a consensus
statement to “summarises the issues faced by high-performance athletes and
their support team (coach, trainer, nutritionist, physician) when considering the
use of supplements, with the goal of providing information to assist them to
make informed decisions.” The document offers a definition of “supplement” and
a summary of the prevalence of, and rationale for, use by athletes; assessing
the evidence base for supplement use; adverse effects; and practical
implications. The document also offers two decision trees to help reach an
informed decision. Some supplements that are specifically discussed include vitamin
D, iron, calcium, caffeine, creatine, and sodium bicarbonate.
