based on the assumption that human blood can survive in a vampire for about the same amount of time it can in a human body, vampires would only need to feed three or four times a year (red blood cells live about 110 days on average). this would be if they completely drained all their victims.

humans can survive losing up to about 40% of their blood, which means that a vampire pushing their limits with each victim would probably need to feed 12 times a year minimum

so like once a month

Hey guess what else happens once a month involving blood

omg no

Now that’s recycling

“Actually, period blood would be really good for a vampire; it’s incredibly nutritious, because it’s supposed to feed a foetus! And it’s probably the cleanest blood in the human body. It’s sterile.” My wife contributed.
