Note: I’m working on a major new project to make it easy for normal people to understand their microbiome test results. Meanwhile, if you’ve tested yourself with uBiome or others, please contact me and I’ll be happy to help you (if you give me your data!)

For “final” versions of my microbiome experiment summaries, please see my entries at Personal Science and the Microbiome on Medium.

Richard Sprague: "Fish Oil Makes Me Smarter" from Quantified Self on Vimeo.

Following an experiment originally proposed by the late UC Berkeley psychologist and Quantified Self pioneer Seth Roberts, I tested the effect on brain reaction time (BRT) of taking fish oil supplements. Surprisingly, periods of taking fish oil corresponded to significantly higher scores on the test, even when controlling for sleep and other factors such as alcohol consumption. I speculate on why this effect may be real, and suggest how the BRT may be useful in discovering similar effects. I wrote up my results here and you can run the same experiment using Seth’s original R code kept on Github.
