So, I would say that it definitely has an impact. Perhaps it would have worked better with a smaller dose.
For my biology, L-theanine (200 mg) rounds out caffeine by stamping out the anxiety-inducing effect. By itself it just gives me a headache sometimes.

My view on this is if you don't find any effect or a tiny effect (the case here) that is already useful information. For most supplements, my bet is that you won't even benefit from a placebo effect. And if you do find an effect, then you should do a more high-effort self-blinded test.
Seems like a nice way to have some weird dreams while probably improving my health (high dose B vitamins seem to do great things for mental disorder and the only apparent downside is colorful piss and possibly turning into a cherry).
For people who don't do vita-drugs, there's always tea, coffee, chocolate, and matcha.
I just realized this week I haven't been biting my nails and from this popping up thought about it, went and checked, and the new magnesium drops I started taking have theanine.
fitbits and similar are fine for measuring awake vs asleep but really terrible at breaking up the stages

Coffee gives me the anxious jitters. L-theanine turns that into focused alertness. I have reduced my coffee intake overall and supplemented my caffeine intake with a small glass of energy drink each day (not a whole can).
My daily supplements intake includes L-theanine (the brand depicted by the video thumbnail in the linked post), St Johns Wort and an IBS support supplement (NutraLife Gut Relief) that contains 2000mg of glutamine per dose.
All of that really helps with anxiety and depression. If I want extra energy, throw in some L-carnitine.
Been mucking around with huge doses of B Vitamins (especially B3/Niacin) and 5-HTP (a serotonin precursor). Both of those are rather, uh, effectful. 500mg+ Niacin will turn you red unless you're actually deficient. And you do not want to mess with the 5-HTP and alcohol at the same time, plus 5-HTP can cause some nasty side effects in some people.
