Most studies I've seen say the opposite. Magnesium oxide is one of the most poorly absorbed forms of magnesium.
"Thus, magnesium citrate was more soluble and bioavailable than magnesium oxide. Magnesium bioavailability from magnesium citrate and magnesium oxide. - PubMed - NCBI
"We conclude that there is relatively poor bioavailability of magnesium oxide, but greater and equivalent bioavailability of magnesium chloride, lactate, and aspartate."
Bioavailability of US commercial magnesium preparations. - PubMed - NCBI
"We conclude that a daily supplementation with Mg citrate shows superior bioavailability after 60 days of treatment when compared with other treatments studied."
Mg citrate found more bioavailable than other Mg preparations in a randomised, double-blind study. - PubMed - NCBI
There was a study where paymanz used magnesium oxide and he felt good on it
