For relaxation and sleep, take them 30 to 60 minutes before bed as part of your wind-down ritual. Want both? Split your dose, one or two capsules in the morning and the rest in the evening.

Brain magnesium builds with daily use, so stay consistent: many notice better sleep within the first week, with cognitive benefits peaking around four weeks. For the ultimate brain stack, pair it with Momentous Creatine, which also supports cognitive function.
