Ep. 290 - Is Caffeine an Overrated Supplement for Lifters?

Ep. 290 - Is Caffeine an Overrated Supplement for Lifters?

Caffeine is incredibly popular among lifters and non-lifters alike. In a variety of cultures all across the globe (including the iron culture), caffeine is a daily staple. While most people use caffeine for a morning boost of energy, lifters have long used caffeine as a performance-enhancing supplement. There is a tremendous amount of evidence reporting acute ergogenic effects from a single dose of caffeine, but there is a surprising lack of research addressing critical questions about caffeine's utility as an "everyday" pre-workout supplement. In today's episode, Eric Trexler reviews a new study suggesting that caffeine improves performance when consumed in the morning, but not in the evening. This is followed by an in-depth discussion about when caffeine may (or may not) be effectively used as a performance-enhancing supplement, and how to balance potential tradeoffs between acute performance enhancement and sleep disruption.
