Frequently Asked Questions

1. What is Magtein®?
Magtein® is a patented form of Magnesium L-Threonate, originally developed by researchers at the Massachusetts Institute of Technology (MIT). Unlike conventional magnesium supplements, Magtein® is the only form clinically proven to cross the blood-brain barrier, making it uniquely suited to support cognitive performance, memory and sleep quality.

Magnesium is involved in over 300 biochemical processes in the body, yet many adults fall short of the recommended daily intake. Optima Max Magnesium is formulated to deliver a consistent, science-led dose for individuals who value cognitive resilience and restorative sleep.

2. Who is it for?
Magnesium is suited to:
  • Individuals looking to support cognitive performance, memory and mental clarity.
  • Those seeking better sleep quality and healthy sleep architecture.
  • People navigating high-stress periods who want to support mood and calm.
  • Anyone following a science-led longevity or neurological protocol.
  • Those complementing NAD+, Omega-3 or adaptogenic regimens.

3. Can I take it with other supplements?
Yes — Magnesium pairs particularly well with brain, sleep and nervous-system actives, and is a foundational supplement within most longevity and wellness protocols.

Pairs particularly well with:
  • Neuro Optimiser (NR) — like Magtein®, NR crosses the blood-brain barrier, making this a powerful pairing for cognitive performance and brain energy.
  • NAD+ Brain Booster Spray — direct neurological NAD+ support that complements Magtein®’s effects on memory and cognition.
  • Ashwagandha — works synergistically with Magnesium to support sleep quality, stress resilience and nervous system regulation.
  • Omega-3 PRO — foundational support for brain health, mood regulation and cognitive longevity.
A note on combinations to be mindful of: Magnesium can interact with certain antibiotics (such as tetracyclines) and blood pressure medications, so consult a healthcare professional if you are taking either. Very high doses may also have a mild laxative effect.

4. What makes Magtein® different from regular magnesium?
Most magnesium supplements — including citrate, oxide and glycinate — are useful for general magnesium support, but they share one major limitation: they do not effectively cross the blood-brain barrier. This means their benefits are largely felt in the body, not the brain.

Magtein® (Magnesium L-Threonate) is different. Developed by researchers at MIT, it is the only form of magnesium clinically proven to raise magnesium levels in the brain, supporting synaptic density, memory, learning and sleep architecture.

Optima Max Magnesium uses Magtein® at a clinically researched dose, designed for individuals who want magnesium’s benefits to reach where they matter most — the brain.

5. When will I see results?
Many users report improvements in sleep quality within the first 1–2 weeks of consistent use. Cognitive benefits are typically associated with longer-term, daily intake as part of a structured wellness routine.
