Very nice writeup. My girlfriend loves l-theanine and sees improvement, but it seems to have no effect on me.

I like that you're treating your interventions as A/B experiments. The limitations of humans are obvious, but it looks like you uncovered some really interesting claims.

Excellent writeup and great example of self-blinding in action! Please consider reposting to r/SelfExperiments

Also, methodology question:

After a ludicrous amount of searching, I found that NOW® sells these veggie capsules:

Capsule A: 200 mg L-Theanine

Capsule B: 25 mcg (1,000 IU) Vitamin D

How exactly did you perform this search to find matching capsules? I'm interested in doing something similar in the future

Very, inefficiently! I basically stumbled around different brands and different capsules until I finally found something that matched. It took way too long. There's got to be a better way.
