You are looking at 100 capsules of Magnesium Threonate with 500mg per capsule.
Magnesium Threonate allows magnesium to be absorbed more easily than other kinds of magnesium. Importantly, Magnesium Threonate can cross the blood-brain barrier, which allows it to have effects on cognition. One animal study with Magnesium Threonate showed an 18% improvement in short-term memory and a 100% improvement in long-term memory (Slutsky, 2010). It also improves anxiety responses (Abumaria, 2011).*
