Amount of magnesium per capsule - is 750mg too high?

This may seem an overkill of an answer, but the context is important ...

When looking at the label quantity of magnesium, you always want to look at the 'Elemental Magnesium' amount. This is the total amount of pure / absorbable magnesium in each capsule, which in our case is 90mg per capsule.

Magnesium is never simply formulated as pure magnesium as this causes too much stress on the stomach being a salt mineral, so it it always bound to another compound, like glycine to make magnesium glycinate.

So the 750mg in each of our capsules is magnesium (90mg) & glycine (660mg).
