l-theanine at same time as caffeine/ephedrine

"L-theanine also has several related applications. It has been shown to help nullify the jittery effects of caffeine. One study with mice showed that theanine decreased convulsions induced by high dosages of caffeine. “L-theanine has also been found effective in reducing the hypertension and disturbance of sleep often associated with caffeine,’ she explained.”

Anyone have an opinion if taking L-theanine at the same time as caffeine/ephedrine would take away from the effectiveness of the two?

Theanine is naturaly present in tea, doesnt seem to nullify tea ya know?

we did a study last year (published at the Annual Conference of the American College of Nutrition testing a supp with E+C and L-theanine (amongst the ingredients) and it did not “interfere” with the E+C efficacy. The product was Norexin by Biotech

Theanine puts your in alpha state. I take it when I want to relax, it works great, no drowsiness or sleepiness, nice relaxed feeling.

Thank you.
