Won't caffeine make me shaky?
That's what most golfers think. Here's what the research actually says.
Caffeine sharpens your focus. On its own, it can also rev you up. But pair it with L-theanine and the picture changes. In a 2008 study, L-theanine blunted the rise in blood pressure that caffeine caused on its own.* In a 2007 study, L-theanine lowered heart rate during a stressful mental task.*
And the pair doesn't cost you focus. It sharpens it. In a 2008 study, people who took two parts L-theanine to one part caffeine got faster and more accurate and were less thrown off by distractions.* A 2010 study at nearly birdiegum's exact dose found it helped people stay focused during a demanding task.*
That's exactly why we doubled the L-theanine.
We didn't guess at the ratio. We matched the one researchers studied. Every piece has 80mg L-theanine to 40mg caffeine. Just 40mg of caffeine per piece, and you control how many you chew.
We took that ratio. We put it in a piece of gum. We made it for golfers.
