  • 2g Magtein® per serving (145mg magnesium): The only patented form of magnesium L-threonate clinically shown to cross the blood-brain barrier and elevate brain magnesium levels.
  • Sleep quality without sedation: Brain magnesium regulates the nervous system signals behind restorative sleep. Replenish it and sleep depth shifts — no melatonin, no morning grogginess.
  • Cognitive function and memory: Magtein® increases synaptic density and plasticity — key factors for learning, memory retention, and mental clarity.
  • Calm without drowsiness: Supports the body's stress response and relaxation mechanisms through magnesium-dependent enzymatic reactions.
  • Developed at MIT: Magtein® was developed by neuroscientists at the Massachusetts Institute of Technology, including renowned magnesium researcher Dr. Guosong Liu.
  • NSF Certified for Sport®: Independently tested for banned substances and label accuracy. Vegan, gluten-free, GMO-free. Take 3 capsules 30–60 minutes before bed.

Momentous Magnesium L-Threonate is built specifically for the brain. Each serving delivers 2g of Magtein® — the only patented form of magnesium L-threonate clinically shown to effectively cross the blood-brain barrier and elevate brain magnesium levels.

Most magnesium forms (citrate, oxide, glycinate) work systemically in the body but don't deliver significant amounts to the brain. Magnesium L-threonate combines magnesium with L-threonic acid — a metabolite of vitamin C — to act as a carrier that escorts magnesium across the blood-brain barrier.

Key benefits:
• Sleep quality — supports deeper, more restorative sleep without sedation or grogginess
• Cognitive function — supports focus, memory retention, and mental clarity
• Synaptic health — increases synaptic density and plasticity, critical for learning and memory
• Nervous system support — magnesium is a cofactor in 600+ enzymatic reactions including those that calm the nervous system
• Stress response — supports the body's natural relaxation mechanisms

Magtein® was developed by a team of scientists at MIT, including the renowned neuroscientist Dr. Guosong Liu. It's the most studied form of magnesium L-threonate with multiple animal and human studies supporting its neurological benefits.

Take 3 capsules 30–60 minutes before bed for sleep support, or earlier in the day for cognitive support — some users find it sedating in the morning, so test your response. Sleep improvements often noticeable within 7 days; full cognitive benefits build over 3–4 weeks of consistent use.

Momentous Magnesium L-Threonate is NSF Certified for Sport®, vegan, gluten-free, and GMO-free. Independently tested for banned substances every batch.

How is this different from regular magnesium?

Most magnesium forms (citrate, glycinate, oxide) work in the body but don't effectively reach the brain. Magnesium L-threonate — specifically Magtein® — uses L-threonic acid as a carrier to cross the blood-brain barrier. It's the only form clinically shown to raise brain magnesium levels.

When should I take it?

For sleep support, take 3 capsules 30–60 minutes before bed. For cognitive support, take it in the morning or early afternoon. Some users find it slightly sedating, so test your individual response with daytime dosing first.

How long until I notice results?

Sleep quality improvements are often noticeable within 7 days. Full cognitive benefits — focus, memory, mental clarity — build over 3–4 weeks as brain magnesium levels rise. Be consistent.

What's the difference between Magtein® and generic magnesium L-threonate?

Magtein® is the patented, clinically studied form developed at MIT. Multiple human and animal studies back its specific role in raising brain magnesium and supporting synaptic plasticity. Generic magnesium L-threonate may use lower-quality raw material without the same research.

Can I take this with other Momentous sleep products?

Yes — Magnesium L-Threonate stacks well with Apigenin and L-Theanine for sleep (this is the Nightly Sleep combination). You can also take it alone if you only need magnesium support.
