why l-theanine rides along

twice the caffeine in every tablet, and why the ratio never moves.

why l-theanine rides along

every zingiez tablet carries 10mg of l-theanine alongside 5mg of caffeine. twice the caffeine, in every single tablet.

the ratio is the design

because it rides in the tablet rather than in the serving, the ratio holds no matter what dose you build. five tablets is 25mg caffeine and 50mg l-theanine. twenty tablets is 100mg and 200mg. you cannot accidentally build a dose that drops it.

it is there to prevent the crash. the landing should match the lift.

where it comes from

l-theanine is an amino acid found in tea leaves. it is why a cup of green tea reads differently from the same caffeine in coffee.

figures for zingiez come from the product label. figures for other products are published ranges that vary by brand, size, and preparation. nothing here is medical advice. contains 50mg caffeine per serving. not recommended for children, pregnant or nursing women, or those sensitive to caffeine. do not exceed 4 servings (40 tablets) per day.

one tablet is 5mg

there are a hundred in the tin. take five, take twenty.
