Msm + pepto deadly combination?
 

Just curious?

Makes everything black

Perhaps you could explain what Msm and pepto are?

Just pink OTC stuff that is best not to take together
(Makes your tongue black)

Not serious as long as you have plenty of time to detox if it happens

i dont think anything serious happens.

it's the Bismuth that colours.

But pepto is short term use only, as bismuth is a heavy metal, and even if it's pretty nontoxic it's still harmful in long-term, as it accumulates in the body
