02 · Our approach
Clearly listed amounts. Published ingredient research. Straight answers. The finished Pre-Shift Focus formula has not been clinically tested.
Haskell et al., 2008
A 2008 study by Haskell and colleagues gave healthy adults 150 mg caffeine with 250 mg L-theanine and measured selected cognitive tasks in a lab. It did not test this product, and it did not study officers, firefighters or EMS crews.

Rhodiola has a long traditional history, but the research is limited and results are mixed. We include a standardized extract and make no promise about what it will do for you.

B vitamins, vitamin D3 and magnesium are included as nutritional support, each at a clearly listed amount. They are not a substitute for balanced meals.
