Magnesium for Foundational Health

TL;DR
Magnesium is involved in over 300 enzymatic reactions in the body — from energy production and DNA repair to sleep, mood, and brain function. Yet an estimated 50–70% of New Zealand adults are deficient. Magnesium L-Threonate + Glycinate provides the two most bioavailable and brain-penetrant forms to support foundational health, stress resilience, sleep quality, and long-term cognitive function. This is one of the highest-ROI daily supplements for almost everyone.

Evidence Rating: ⭐⭐⭐⭐⭐ Robust
(Backed by hundreds of studies and meta-analyses on sleep, anxiety, blood pressure, depression, and cognition. Consistent expert consensus from Dr. Andrew Huberman, Dr. Peter Attia, and Dr. Rhonda Patrick.)

What the Research Shows for Foundational Health

Magnesium is a cofactor in hundreds of biochemical reactions. Deficiency is linked to poor sleep, increased anxiety, brain fog, muscle tension, and accelerated ageing. Modern diets, stress, caffeine, and New Zealand’s depleted soils make deficiency extremely common.

Magnesium L-Threonate is the only form proven to raise brain magnesium levels, while Magnesium Glycinate supports calm and sleep. Together they address the most common deficiency symptoms New Zealanders experience daily.

Key Benefits for Foundational Health

  • Better sleep quality and nervous system recovery
  • Reduced brain fog and improved daily mental clarity
  • Calmer response to daily stress
  • Support for healthy ageing and long-term cognitive function
  • Foundation for almost every other health goal (energy, mood, recovery, brain health)

Key Studies

  • Huberman Lab Podcast — Sleep Toolkit series (2023–2025). Search YouTube or Spotify for “Huberman Lab Sleep Toolkit” or “Huberman magnesium threonate”.
  • Slutsky et al. (2010). “Enhancement of learning and memory by elevating brain magnesium.” Neuron. DOI: 10.1016/j.neuron.2009.12.026. A 2016 randomized, double-blind, placebo-controlled human trial (Liu et al., Journal of Alzheimer’s Disease) showed Magnesium Threonate improved cognitive function in older adults (DOI: 10.3233/JAD-150538).
  • Multiple reviews (2020–2025) confirm widespread magnesium deficiency in modern populations and the broad benefits of repletion for sleep, mood, and healthy ageing.
