It is strange to discuss L-theanine with vitamin D as one has nothing much to do with the other. It could've been better to compare L-theanine with a placebo (cellulose) which is how research conventionally works.

L-theanine at 200-300 mg before bed is extremely useful for canceling excessive caffeine while trying to sleep at night. Add piperine to the mix for possible further cancelation of caffeine. [PMID 35684048]

That's the idea, vitamin D was used as a placebo. They bought vitamin D supplements rather than cellulose because the supplier sold both L-theanine and vitamin D and the pills looked (nearly) identical.

Personal anecdote, Vitamin D is a horrible placebo.

I have been trying to increase my Vitamin D levels for 15 years now but I just can't tolerate this supplement.

  Lower dosage: ~1000 IE -> side effects come after around 3-4 days of daily intake.
  Higher dosage: ~5000 IE -> side effects after a few hours.
I tried following most advice over here in the past but it did not work: https://vitamindwiki.com/Vitamin+D+Cofactors+in+a+nutshell

I'll just live with my low blood Vitamin D levels.

What side effects? It promotes energy in just a few hours, so take it early in the day. Your link is not loading. Ensure you have sufficient calcium and magnesium as cofactors.
