Zinc amount

[ssj4goku1992]

Hi guys,

I have a question. I do not understand a few things about supplementation, and I am hoping that you guys can help me out here. (I asked the pharmacists at the local pharma but they had no idea about it...)

For example, I bought a bottle of Zinc tabs from GNC. It is written on the back of it like this:

Amount per serving-------------% Daily Value

Zinc (as Zinc Gluconate) 50 mg 333%

What does that mean? That I have 50 mg of Elemental Zinc FROM Zinc Gluconate? ( Meaning that I would have about 500-600 mg of Zinc Gluconate?)
Or does that mean that I have 50 mg of Zinc Gluconate (Meaning that I would have about 7.5 mg of Elemental Zinc in it?)

Same with my Magnesium bottle from the same GNC.

Magnesium (as Magnesium Oxide and Magnesium Gluconate)-----------250 mg.

Does that mean that I have 250 mg of Elemental Magnesium FROM Oxide and Gluconate? Or I have 250 mg of Oxide and Gluconate? Which would make my elemental magnesium dose lower?

Thanks for your answers.
