There's a seemingly infinite market for workout boosters, supplement-laden drinks that purport to take your exercise capacity to EXTREME levels. But new research shows that one of the best workout supplements might already be one of your daily habits: coffee.
If you think I’m just a biased coffee-holic, you’re probably right. But I’ve also seen the studies that suggest coffee protects against heart disease, diabetes, Parkinson’s disease, liver cancer, and more. The point is, if you’re not drinking coffee, you probably should be (albeit without 4,000 calories of added sweeteners and saturated fat), and if you’re an athlete of any kind, you should consider taking a double dose.
Caffeine as a performance-enhancing drug
Show me an athlete, I’ll show you a person who's well versed on the performance-enhancing benefits of caffeine supplementation. In fact, caffeine is considered a “controlled or restricted substance” by the International Olympic Committee (IOC), with limits set on urine tests to 12ug per milliliter by the IOC and 15ug per milliliter by the NCAA.
