QUESTION
is there a caffeine-free l-theanine gum?
nula calm gum is caffeine-free. a serving is 100mg l-theanine and 50mg gaba in peppermint gum you chew for at least three minutes. many nootropic gums pair l-theanine with caffeine on purpose — neuro energy and focus gum lists 40mg caffeine with 60mg l-theanine. if the goal is calm rather than energy, read the caffeine line first.
yes — and most chewable theanine products are not
l-theanine shows up in two kinds of gum. one is an energy product that uses theanine to smooth caffeine. the other is a calm product with no caffeine at all. the packaging language overlaps. the caffeine line does not.
nula is the second kind: peppermint chewing gum, caffeine-free, with 100mg l-theanine and 50mg gaba per serving. suggested use is one to two pieces, chewed for at least three minutes.
the caffeinated default
neuro's energy and focus gum lists caffeine 40mg with l-theanine 60mg on its own page as of august 17 2026. that pairing is well studied — nawarathna and colleagues (2025) tested a high-dose theanine-caffeine combination for selective attention under acute stress.
it is a sensible product if energy is what you want. it is the wrong product if you are already wired, it is late in the day, or caffeine is the thing you are trying to avoid.
how to read a label
if the page does not say caffeine-free, do not assume it is. a missing caffeine line is not a claim. nula states none; some other gums state a milligram amount; some pages simply do not disclose it.
nula is not a medicine and not a sleep aid. it is a dietary supplement for occasional stress, formulated for calm without sedation.
common follow-ups
none. it is caffeine-free.
because theanine-plus-caffeine is a studied energy stack. the theanine is there to take the edge off the stimulant, not to be the whole product.
it is a different job. nula is built for calm. a caffeinated theanine gum is built for alertness. pick the one that matches the moment.
