Completed the rainbow today. 15 years in urology but this was my first green. Patients took B2 (makes urine very yellow) and methylene blue (makes urine blue) together and here we are.

There’s a sleeping supplement in Japan. It’s a little bottle you drink and it makes your pee highlighter yellow.

Some B vitamins do this, forgot which one, I remember whenever I take a B complex I have like highlighter pee the next day lol

Its B2, SWIM likes to spoof drug tests

But vitamin B in sleeping aid seems a bit counter intuitive, since it's one of the go to brag things on energy drink cans together with caffeine and taurine. But I am not any kind of expert in vitamins, so if anyone would like to correct me that would be lovely

I watched a video about a guy who's insomnia was cured by drinking energy drinks. He had a b12 deficiency which caused lack of sleep and the energy drinks provide many times your RDI of b12.

To say it really easy. B-Vitamins make your nervous system work normally and a normal nervous system wants to sleep at night.

All the "more energy" is just your normal energy finally unlocked so your fit over the day, power yourself out for once and sleep even better.

It’s B2 riboflavin that makes it neon, not sure exactly what it does, but yeah I think b vitamins help with energy so maybe there was something else in the sleep aid. But if u take anything with q lot of B2 it’s harmless except u will pee neon yellow. It’s kinda interesting

B12 is the main one marketed as providing energy. B2 is the one that makes your urine very bright yellow.

Thiamine b1 or. B12 but I know it's Thiamine
