@literally45-- Yea, this is why doctors recommend getting fat soluble vitamins like beta carotene from food rather than from supplements. Food doesn't contain enough of the vitamin for us to overdose on it.
I think I once overdosed on beta carotene. I didn't have skin discoloration but I did feel very tired and nauseated for several days. I didn't talk to my doctor about it but I noticed that the symptoms disappeared when I stopped taking my beta carotene supplement.
