I have always concidered this channel serious, but they are making very bold claims.

50% of our dopamine and 90% of our serotonin is created by microbes in our guts.

Is this true and could someone put this into context? Like, what's the difference in a person if they have half the dopamine and 1/10th of the serotonin? Would this be the effect if you removed the microbes?

  • I think the last question is not a skeptical one (but still an interesting question). Should we mod that out, or maybe leave it in as a bonus question? – JasonR Sep 30 '16 at 12:22
  • It must be noted that even if the gut microflora produced 90% of the body serotonin, it doesn't mean that removing the gut microflora results in 90% decrease in the amount of serotonin the body has. It might up its own production instead. – John Dvorak Sep 30 '16 at 14:36
  • @JasonR I think all skeptisicm must be put in context, they do not claim that in the video, but the video is refering to the stomach as the second brain, so I think it's important to understand weather the information they are providing is supporting that claim. – Kristoffer Nolgren Oct 3 '16 at 8:14
  • @JanDvorak that's what I'm thinking, but I have no idea... – Kristoffer Nolgren Oct 3 '16 at 8:14
