Finally a way to look like A Jersey Shore star that is safe!

Yeah I've also read that since it needs to be converted to vitamin A you don't need to worry about over consumption. Your body will just stop creating vitamin A in a similar way to how your intestines stop absorbing food when you consume too much vitamin C. Neither is really possible on a diverse diet though and even otherwise except possibly from liver or pills.

Haha, I guess there is no toxicity but a nice side effect: I started to eat loads of carrots/day a couple of weeks ago and everyone is noticing my nice tan, despite the bad weather we have right now in Austria g

My infant son only ate meat, carrots, and sweet potatoes for most of his post-milk phase up until he was solidly two years old... it was simply what he preferred. He was very, very healthy... but looked like a little chubby Ompa Loompa with the baby curls and orange skin.

I think (non expert here) it is fat soluble but there is no upper limit, as in it's not toxic if you have too much of it (but it might turn you orange!)

Carotenosis is caused by eating too much beta-carotene, such as from sweet potatoes or carrots. Your skin turns orange, but it is otherwise harmless and goes away when you reduce your intake of carotenes.
