Caffeine is one of the most extensively studied compounds in human performance research. It works primarily by blocking adenosine receptors -- adenosine is the neurotransmitter that signals fatigue -- thereby supporting alertness and reducing perceived exertion. Sourcing caffeine from green tea keeps the ingredient origin clean and provides it alongside naturally occurring trace polyphenols. At 80 mg per strip, the dose is deliberately moderate -- enough to support focus and energy without the cortisol spike associated with very high doses.*

L-Theanine is an amino acid found naturally in tea (Camellia sinensis) that promotes alpha-wave brain activity -- the state associated with relaxed alertness, not drowsiness. Human clinical studies have demonstrated that pairing L-Theanine with caffeine in a 2:1 ratio can reduce caffeine-related jitteriness and support attention-switching and working memory better than either compound alone. The 160 mg dose in this strip reflects that evidence-based 2:1 ratio precisely.*

Vitamin B12 is a water-soluble vitamin essential for red blood cell formation, neurological function, and the conversion of food into cellular energy via the mitochondrial pathway. Methylcobalamin is the biologically active, coenzyme form -- it does not require conversion by the liver before the body can use it, unlike cyanocobalamin. The high % DV reflects that B12 has no established upper tolerable limit and excess is excreted; the dose is consistent with what is commonly used in sublingual and fast-absorbing formats, where bioavailability is already improved over standard oral forms.*
