Someone has posted about a personal case of vision deterioration after taking lumina and a proposed mechanism of action. I learned about lumina on lesswrong a few years back, so sharing this link.

For the past several months I have been slowly losing my vision, and I may be able to trace it back to taking the Lumina Probiotic. Or rather, one of its byproducts that isn’t listed in the advertising
I don’t know enough about this to make an informed judgement on the accuracy of the proposed mechanism.
fwiw I made my account in January, which I guess is still very new relative to average age of account here but hopefully means you can trust I didn’t make this account just to drop a link to the lumina post.
