[Popeye the sailor man] can anyone Gain godly super strength from the spinach or is it just Popeye?

I never thought about it before but is he the only one who gets godly strength from the spinach or could anyone get strong from it? And if so why hasn't every person In the world bought that spinach by now? Why is Popeye the only one eating that stuff????

It doesn't grant him godly strength. It unlocks it.

He originally gained his super strength by rubbing the head of the Whiffle Hen, which can grant powers. Usually luck, but how luck manifests is what a person needs, and Popeye generally needed strength and durability. Because this was granted so often, it sort of morphed into him needing to eat spinach to get his powers, which is a lot more convenient than having to rub a chicken's head all the time.
