Is there such a thing as a dietary supplement that will make your skin give off a smell that will Repel Sharks?

There actually has yet to be a single shark repellent that actually works. And, like the two people before me said, sharks are not very dangerous. Toasters, coconuts, christmas lights, chairs, hippos, cars, vending machines, and bees are all more dangerous than sharks, and each one kills more people in a year than all sharks do in a decade. Hope this helps!
