The second part of the Jockology series on supplements is now up on the Globe and Mail site, taking a look at probiotics, vitamin D and ZMA. I expect to get some disagreement on this one — ZMA, in particular, has a very strong following, and vitamin D is the hottest supplement on the planet these days. In both cases, it seems clear that correcting deficiencies can have an enormous effect, both on performance and on health in general. But the existing research hasn’t convinced me that athletes need more than anyone else.
That being said, these questions are far more complex than the “true” or “false” labels that appear in the newspaper column. So if you think I’ve missed some key information or gotten it wrong, let me know!
