Does consuming L-theanine with caffeine, either in drink (like matcha) or in pill form, affect the half-life of caffeine?

I have heard something like "L-theanine slows caffeine absorption", so I am inclined to assume that caffeine's half-life may increase, but I have no idea if one can jump to that conclusion. And I cannot find anything on this topic.

Isn't this more of a chemistry (how do these compounds interact?) or biology (how do these compounds interact in the human body?) question? – JJJ Dec 24 '20 at 20:03

Yes it is. I did not fund such forums but also found the Medical Sciences StackExchange, and asked there. – João Bravo Dec 25 '20 at 14:38

I’m voting to close this question because it's not really about coffee and the cross-site dupe op med.SE already received an answer. – JJJ Dec 25 '20 at 18:34
