MaxLife – Max-Mag (105 Caps)

Most magnesium supplements don't reach the brain. The blood-brain barrier is selective, and standard magnesium forms — oxide, citrate, glycinate — are largely excluded. Magnesium L-threonate (Magtein) is the only form clinically shown to raise magnesium levels in cerebrospinal fluid and restore synaptic density in the hippocampus and prefrontal cortex.

What it supports

• Brain magnesium levels — the critical differentiator from other magnesium forms
• Synaptic density in the hippocampus and prefrontal cortex (memory and executive function)
• NMDA receptor regulation, reducing excitotoxicity and neuroinflammation
• GABAergic signalling and deep slow-wave sleep quality
• Cognitive performance and stress resilience
• Calcium regulation and bone health via co-factors D3 and K2

Ingredients

Magnesium L-Threonate (as Magtein) — 2,000mg
Vitamin D3 (cholecalciferol) — 20mcg (800 IU)
Vitamin K2 (MK-7) — 120mcg

Per 3-capsule serving (35 servings per bottle).

Directions

Take 3 capsules daily. Recommended protocol: 2 capsules in mid-afternoon, 1 capsule one hour before sleep.

Why we stock it

Magtein is the only magnesium form with clinical evidence for penetrating the blood-brain barrier and raising brain magnesium concentrations. Synaptic density in the hippocampus — central to memory consolidation — declines with age and chronic stress, and magnesium regulates synaptic plasticity directly via NMDA receptor modulation. The split-dose protocol (2 afternoon, 1 pre-bed) mirrors the research design and is worth following — the sleep benefit from the pre-bed dose is distinct from the cognitive benefit from the afternoon dose.
