Magnesium for Performance & Energy

TL;DR
Magnesium L-Threonate + Glycinate supports physical and mental performance through better sleep quality, faster recovery, stress resilience, and cognitive clarity under pressure. Athletes, high performers, and anyone in demanding roles benefit from addressing magnesium depletion caused by intense training, high stress, and poor sleep. Dr Andrew Huberman recommends it as foundational for exactly this reason.

Evidence Rating: ⭐⭐⭐⭐ Strong
(Multiple studies support sleep, recovery, and cognitive benefits in high-stress and athletic populations. Strong expert consensus from Huberman’s performance protocols.)

What the Research Shows for Performance

Intense physical training, high mental workload, and chronic stress all deplete magnesium stores. Deficiency leads to poorer sleep, slower recovery, increased perceived effort, and reduced cognitive sharpness — all of which directly impact performance.

Magnesium L-Threonate supports brain-level recovery and focus, while Magnesium Glycinate promotes deeper sleep and nervous system calm. Together they create the foundation for sustainable high performance.

Key Benefits for Performance & Energy

  • Faster recovery from training and high-stress periods
  • Deeper sleep and better overnight restoration
  • Improved focus and decision-making under pressure
  • Reduced mental and physical fatigue
  • Greater resilience to daily stress and cortisol load
