L-theanine
Yeah! I've personally experimented (n=1) quite thoroughly with it. It truly reduces or eliminates caffeine jitters.This product is excellent for energy on the go. Caffeine and l-theanine in a single pill. I keep a few in my bag. I don't know if there's anything special about this particular product. There are other ones that may be better/cheaper. But I've gone through a few bottles of it in the past years and am pleased: https://www.amazon.com/gp/product/B07MQWJYJ3
You can buy it separately but I don't see the point.
Well, clearly a lot of people like coffee and probably don't want to have a side of green tea with their coffee, so... you can see the point, right? =)I do buy it separately. It's dirt cheap. I stir it into my coffee. Reduces caffeine jitter.
That all said, editorial time: caffeine is not awesome. It is a psychoactive substance (duh) and eventually it goes from "fun boost" to "I need this to feel normal." At least for me. I do have some every day but my goal is always to drink the smallest reasonable amount for me in order to manage my energy. Respect to people who drink 0mg.
Biggest issue I think would be making sure that there aren't any tells like flavor or some quality of the additive.
Brew identical looking bottles of cold brew. Label the bottoms 1 through whatever. Mix them up. Label the lids A through whatever. Probably need to add some creamer to mask any possible sediment. Drink from them throughout the week. Note the lid label and your reaction. At the end of the test period look at the bottoms of the bottles to correlate the controls and placebos with your experiences.
I personally don't feel the need with this particular thing though. It's a fairly pronounced difference.
It's also not really susceptible to the placebo effect IMO. Could I imagine some vague promised positive effect? Absolutely yes. Could I imagine the erasure of jitters? I don't think I could placebo that away.
Anyway as linked in another post this is well-studied.
That said:
- I'm middle aged and have had tens of thousands of cups of coffee
- The difference is pronounced, not subtle
- It's well-studied https://pubmed.ncbi.nlm.nih.gov/18296328/
FWIW, I've played around with a lot of supplements. Generally the effects are non-existent or subtle. I'm not generally given to a placebo effect wrt this kind of stuff
But caffeine and even coffee specifically seem to have positive health effects. If people are happy with 0mg they should continue that, but if people are happy with low doses of caffeine they should also continue that.
Personally I love coffee, but I limit myself to one cup a day and drink yaupon when I want more caffeine. This results in less sweating, nausea, anxiety. Supposedly yaupon should help with stress relief as well, but I doubt it's a strong enough effect to overcome learning that a new ticket is due in 5 hours.
Extremely speculative and based on nothing but pure, unadulterated dubious armchair/reddit science, but: L-theanine is a (mild) depressant/anxiolytic with reported effects not wholly unlike GABAergic substances' (benzodiazepines, pregabalin, gabapentin, phenibut, alcohol) reported effects. GABAergics modulate or increase GABA-related activity. (GABA is the primary inhibitory neurotransmitter.) L-theanine is structurally similar to glutamate (the primary excitatory neurotransmitter) and interacts with glutamate receptors in a way that inhibits their normal activity. Increasing GABA-related activity and reducing glutamate-related activity can potentially have similar "mellowing" brain effects, like the equivalency of pushing a "slow-down" button with more force and pushing a "speed-up" button with less force.
For some reason, GABAergics make some people more prone to irritability, and, in some cases, can reduce the threshold for anger and rage. Despite not being a GABAergic, I could see L-theanine potentially causing a similar effect in some people.

I've been overwhelmed by Gyokuro before...
I've heard that green tea can calm down the effects of caffeine (despite containing a bit of caffeine itself). Something to try if you don't want to give up coffee like me.
