I'm interested how long the body stores each kind of supplement. I know, for example, that we don't store Vitamin C and so we must have some (fruit etc) every day - whereas we store iron for months, so topping up every so often works fine.
I assume this relates to how quickly we feel it when we aren't having enough of each one? And of course, how often we need to take them.
My real interest is how soon I'll feel the difference now that I've started Vitamin D, but also this is something I have wanted to know for ages with respect to many different vitamins, minerals etc.
I know there are too many to list all, but does anyone know about:
Vitamins A, B group, C, D, E, K, etc...
iron, magnesium, stuff like that
hydrolysed collagen (if anyone here takes it?)
plus the ones I can't think of this afternoon
