I posted that as a joke. I don't think it's an actual risk unless you're one of those morons who overdoses. It does seem like if your skin gets too orange, you have the option of just stopping.
I have my own hypothesis for why these things are not tested properly, we're already off-topic so ...
Looks-maxing supplements are not tested properly and neither is anything else in the supplement market. It's mostly a load of sh*t, meant to grow your hair, your muscles, to improve your boners, your concentration, your memory, your mood, your sleep and to ward off cancer, alzheimers, and heart disease.
Proper dosing studies, proper long-term follow-up, decent sample sizes, etc are all exceedingly rare or non-existent.
I think it's general BS all around and not related to looks-maxing or whatever. The industry likes this state of confusion, this way people buy everything. Pharmacies now have huge shelf space for supplements, it's mostly a scam.
But some stuff works, I wish it were researched properly.
