L-Theanine + Caffeine? | Pourfection Nootropic Coffee Creamer
L-theanine is to caffeine like peanut butter is to jelly.
They just go together!
Research suggest serotonin depletion can cause depression, and cognitive decline, while increased levels can support happiness, and anti-addiction. A dose of only theanine equivalent to 200mg improves cognitive and neurophysiological measures of selective attention (Kahathuduwa et al. 2016) Combining L-theanine with caffeine, at levels and ratios equivalent to 70-140mg, eliminated the vasoconstrictive effect and behavioral effects of caffeine (Dodd et al. 2015).
A study comparing L-theanine dosed with caffeine showed that “the outcome measures of mood were alertness, calmness, and contentedness. Cognitive measures assessed were attentional switch, intersensory attention, and rapid visual information processing” (Camfield et al. 2014).
Pourfection Nootropic Coffee Creamer contains an active dose (250mg) of L-Theanine combined with 110mg (plus unknown amount of your beverage) of caffeine to enhance alertness, calmness and cognition.
