The Momentous Complete Sleep Stack is a sleep support bundle expertly formulated without melatonin to help you fall asleep faster, stay asleep longer, and wake up feeling refreshed and clear‑headed. 

Created from four research‑backed, naturally derived ingredients—magnesium L‑threonate, L‑theanine, apigenin, and inositol—this stack works to calm the nervous system and enhance sleep quality without next‑day grogginess. 

  • Magnesium L‑Threonate crosses the blood‑brain barrier to more effectively support cognitive recovery and anchor deep, restorative sleep cycles.

  • Apigenin is a plant compound found in chamomile, widely known for its gentle, calming effects.

  • Inositol contributes to mood balance and reduces nighttime waking.

Who It’s Best For

  • People who have trouble falling asleep or staying asleep
  • Those looking to improve sleep quality without using melatonin
  • Individuals with high stress levels that interfere with sleep
  • Anyone seeking a natural, non-habit-forming sleep aid
  • Shift workers or frequent travelers needing sleep support without grogginess 

Who It’s Not Ideal For

  • Individuals sensitive to any of the listed ingredients
  • People who prefer a melatonin-based sleep aid
  • Those with medical conditions or taking medications that interact with supplements
  • Children or adolescents, unless advised by a medical professional
  • Individuals looking for a quick-fix sleep aid without focusing on long-term sleep habits

How It Works

Magnesium L-threonate crosses the blood-brain barrier to more effectively help calm brain activity and promote deep, restorative sleep. L-theanine and apigenin work together to relax the mind, reduce stress, and smooth the transition from wakefulness to sleep. 

Inositol supports healthy neurotransmitter function, helping to regulate mood and reduce nighttime awakenings. Together, these ingredients create a non-habit-forming formula that promotes high-quality sleep without the use of melatonin or next-day grogginess.

How to Use It

Take one serving of each product 30 to 60 minutes before bedtime with water. Use consistently as part of your evening routine. Most people report noticeable benefits within the first few days, but full benefits kick in around the two-week mark of consistent nightly use. Do not exceed the suggested serving unless directed by a healthcare professional.
