Yes — every active in Caffy is backed by published human research, and they're formulated to work together: caffeine for drive, L-theanine to keep that energy calm and focused, and whole-food actives that support blood flow and stamina. The science behind each:
Caffeine — 200mg. The engine. At 3 to 6mg per kg of bodyweight (one bar sits right in that range), caffeine is one of the most proven performance aids there is. A meta-analysis of 21 randomized trials found it improves time to exhaustion and sustained output, so you stay sharp deep into the third game instead of fading. (Systematic review & meta-analysis, 21 trials)
L-theanine — 200mg. The reason it stays clean, not jittery. It takes the edge off the caffeine so your heart isn't pounding and your hands stay steady at the kitchen line. Caffeine plus L-theanine is the single most-studied pairing for calm, locked-in focus under pressure. (Hidese et al., Nutrients 2019)
Beetroot. One of the most-researched performance foods there is. Its natural nitrates support nitric-oxide production, which widens blood vessels and helps your muscles use oxygen more efficiently under load. (Wylie et al., J Appl Physiol, 2013)
Pomegranate. A dense source of polyphenols studied for supporting blood flow and vessel dilation, with research linking it to greater exercise tolerance. (Trexler et al., Appl Physiol Nutr Metab, 2014)
Maca. A Peruvian root traditionally used for energy and stamina, studied for supporting mood and perceived energy over time. (Gonzales-Arimborgo et al., Pharmaceuticals, 2016)
Real dark cacao. Not just a wrapper for the actives. Cocoa flavanols raise nitric oxide and are studied in athletes for supporting blood flow and blunting the oxidative stress of hard training, which aids recovery. (Cocoa flavanols & exercise, systematic review)
Stacked together, that's clean, sustained energy — focus that climbs and holds, without the jitters or the crash. Every ingredient and dose is on the label, no proprietary blends.
