The 3AM Stack is built for people who fall asleep but wake in the early hours, often between 2am and 4am. It starts with the day, supporting steady glucose metabolism, rather than relying on the evening alone.
Myo D-Chiro Inositol is taken with food in the morning or early afternoon, deliberately away from the bedtime part of the routine. Myo-inositol and D-chiro-inositol at a 40:1 ratio have a well-studied role in insulin signaling and glucose metabolism, the pathway behind the overnight blood sugar dip that can contribute to waking in the early hours.
Berberine is taken 20 to 30 minutes before the evening meal. It supports glucose metabolism and insulin sensitivity through the AMPK pathway and has credible metabolic evidence behind it.
Magnesium Glycinate closes the day. A 2025 randomised, placebo-controlled trial of magnesium bisglycinate in adults reporting poor sleep found a modest improvement in insomnia severity after four weeks, with the biggest gains in people who started with lower dietary magnesium.
Give the stack two to four weeks to build. For nights that also start with trouble falling asleep, the Fall Asleep + 3AM Combo adds Sleep Formula and Ashwagandha.
