As a matter of fact yes.
Just as an excess of iron is a debilitating condition in a living person, vampires too can suffer from the condition. I have know certain vampires to become very irritable and discomforted by 'what is probably' just that.
They are however able to self-regulate the excess by excreting it from their pores (sweating). A vampire can recover from such an imbalance in a matter of days.
There are 16 known oxides and oxyhydroxides of iron and a 'sweating' vampire can express a few of these, although only one at a time. I know of only five such expressions (not first hand, from records kept by the vampires themselves). Such sweat can therefore be either black, green, orange, red, (or even gold if accompanying with Sulfur poisoning.)
In vampire lore, iron is often considered to be harmful to vampires, with some stories depicting it as a way to ward them off or harm them. This idea likely stems from iron's historical associations with purity, protection, and warding off evil spirits.
no
Since vampires do not exist, they have no effect on the Catholic Church.
with some vampires it doesn't affect them but with the ones it does i shouldn't think so. They were humans after all.
No, because vampires do not exist. You cannot affect anything that does not exist. But that said, it was indeed believed that the holy powers of silver would be extra-damaging to vampires, which were unholy.
There are fictional depictions of vampires with mental disabilities, but in reality, mental disabilities do not affect one's ability to be a vampire. Vampires are typically portrayed as powerful beings with supernatural abilities, regardless of any mental impairments.
The pH is not affected by iron (Fe).
No vampires tend to keep a normal lifestyle and tend to not bring up situations that could possibly expose them for what they really are.
First, vampires don't exist, but if they did, a whip would not kill them. Iron, silver, fire, sunlight, running water are the only things that are supposed to work.
No, caffeine directly affect the absorption of iron. It is the polyphenol compounds in coffee and tea that negatively affect iron absorption. Drinks containing polyphenol compounds should be avoided at least an hour prior to, and and hour after taking iron supplements or eating foods that contain iron to ensure they do not interfere with iron absorption.
It would depend on what the author of the fictional story wanted
it keeps you strong
Vampires never die Edward Cullen is the bomb and Jacob black sucks so they don't die so don't try it Vampires never die until they're burned to death, or staked in the heary.
