Optima Max Magnesium

Take 2 capsules during the day and one capsule one hour before going to bed with water or with a meal during the day. 

Magnesium L-Threonate is typically used daily and consistently, as its benefits relate to ongoing neurological support rather than immediate effects.

⚠️ Do not exceed the recommended daily intake.

✔ Individuals seeking support for cognitive clarity and mental performance
✔ Those prioritising memory, learning, and brain health
✔ People who want to help support restful sleep cycles and daily function
✔ Individuals focused on balanced mood and calm mental state
✔ Those following science-led, preventative wellness approaches
✔ Individuals complementing NAD+, longevity, or metabolic optimisation protocols

Magnesium L-Threonate and NAD+ support complementary aspects of brain and cellular health:

• Magnesium L-Threonate (Magtein®) supports neuronal signalling, synaptic function, and cognitive processes
  
• NAD+ plays a central role in cellular energy metabolism and repair
  

Together, they can be integrated into longevity-focused protocols to support both neurological function and core cellular energy, helping lay a balanced foundation for mental performance and healthy ageing.

• Improves memory and focus
• Supports relaxation and quality sleep
• Enhances mood balance
• Promotes neural plasticity

For a complete brain and energy stack, combine Optima Max Magnesium with Omega 3 and Ashwagandha.

Magtein® is a patented, clinically studied form of Magnesium L-Threonate developed at MIT. It is the only magnesium compound proven to cross the blood-brain barrier and raise magnesium levels specifically in brain tissue. Unbranded Magnesium L-Threonate lacks this clinical validation and EU Novel Food approval.

Standard magnesium supplements (glycinate, citrate, oxide) do not cross the blood-brain barrier effectively. Magtein® specifically targets brain tissue, making it uniquely suited to cognitive and neurological support.

Improvements in sleep quality are often reported within 1 to 2 weeks. Cognitive benefits, including memory and focus, typically build over 4 to 8 weeks of consistent daily use, as supported by published RCT data.

2 capsules during the day (for example, with meals) and 1 capsule approximately 1 hour before bedtime for sleep support.

Yes. Magnesium L-Threonate and NAD+ support complementary aspects of neurological and cellular health and are frequently combined in longevity protocols.

Yes. The Magtein® clinical trials demonstrated good tolerability with no significant adverse events. As with all supplements, consistent daily use within the recommended dose is advised.

Multiple published RCTs support its use. A 2022 double-blind RCT (n=109) showed significant improvements across all categories of clinical memory testing. A 2024 RCT (n=80) demonstrated improvements in sleep quality and daytime functioning. A 2025 RCT (n=100) showed a 7.5-year reduction in estimated cognitive age after 6 weeks of supplementation.

No. Magtein® is a proprietary, patented form that is the only one to have been clinically tested. Generic Magnesium L-Threonate products without the Magtein® brand have not been validated and are not approved for sale under EU Novel Food regulations.

As with all food supplements, certain individuals should exercise caution. This includes people who are pregnant or breastfeeding, those with pre-existing medical conditions, individuals currently taking prescription medication (including blood thinners, diabetes medication, immunosuppressants, or thyroid medication), and those under the age of 18. Supplements are not intended to diagnose, treat, cure, or prevent any disease. We strongly recommend that every client consults a qualified healthcare professional before starting any new supplement, particularly if they have an existing health condition or are taking medication. When in doubt, escalate to the NADclinic clinical team.
