48% of Americans are magnesium deficient. From googling, the hard to absorb inorganic ones are magnesium oxide and magnesium chloride. The easy to absorb organic salts include magnesium citrate, lactate, aspartate, and glycinate.
I also found when I eat eggs, I crave chocolate less. I think it’s the fat content.
(But I expect many just like the sugar.)
Beware blood tests do not reflect the full state of vitamin deficiencies and can be even misleading.
