Vitamin A

[Ramrod]

I have always used herptivite with beta carotene twice monthly for my veiled but never really understood the difference between preformed and proformed vitamin A. Can someone explain the difference and include why one would be used over the other.

PrEformed vitamin A comes from animal sources and is ready to go...the body doesn't have to convert it. It includes retinal, retinyl, retinal, etc. Beta carotene comes from veggies, greens, etc. and is prOformed and has to be converted into vitamin A in the body as do other carotenes. PrOformed sources can't build up in the body and lead to health issues, prEformed sources can.

There is controversy as to whether any or all chameleons can convert the carotenes to prEformed or not.

Would that mean that fresh greens such as dandelion ect. contain proformed vit A

One more thing.... like vitamin D3, vitamin A is fat soluble.
