L-Tyrosine has a "B" rating on Examine.com for its potential effects on attention, mentioning that studies suggest it may be able to preserve attention under conditions of stress, but evidence is limited beyond that.

I am currently in the middle of a blinded trial with L-Tyrosine. Over the course of 20 days during which I intend to focus for sustained periods, I take either 500mg L-Tyrosine or a placebo and record my focus on a scale of 0-10.

This market will be resolved YES if the mean for focus on days taking L-Tyrosine is higher than days taking the placebo.

(This is my first market so I'll keep the resolution criteria simple, but in future I'd like to use a simple model to estimate the posterior distribution of % difference between the placebo and supplement using PyMC, and then resolve YES if that distribution suggests a >50% chance of 2.5% increase in focus/whatever I'm trying to measure. Anyone can feel free to comment if they think that's worth doing or if there's a better approach!)

Extra notes:
- I didn't pick L-Tyrosine for any reason other than it's mentioned on Examine.com, and it's easy to get a hold of.
- I'm 10 days into the trial, but I won't mention how it's gone so far until the trial is complete.
- I won't be betting on this market.
