Magnesium L-threonate is a mineral linked to normal nerve signalling and brain function. This form is built to boost magnesium delivery to the brain, helping educational and cognitive processes through better brain magnesium availability. It’s sourced as a brain-optimised magnesium compound meant to back up neural activity.

The formulation uses magnesium in the L-threonate form to maximise brain delivery and action, with other capsule ingredients giving a suitable delivery matrix.

What Does Magnesium (L-Threonate Form) Do?

Magnesium plays a role in normal brain function and cognition, by aiding brain signalling and synaptic activity. This form helps raise cerebrospinal magnesium levels, supporting synaptic connections and learning processes in line with EFSA-endorsed ideas about mineral function in the brain. Dr. Slutsky from Stanford University found that magnesium L-threonate supplementation improved memory and executive function in older adults.

The main benefit seen is improved cognitive performance through better brain magnesium delivery and synaptic support, aligning with research on brain health and function.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
