Description
Osavi Magtein Magnesium L-Threonate provides magnesium in the patented Magtein form — the only magnesium compound shown in clinical research to effectively cross the blood-brain barrier and raise magnesium levels in the brain. Standard magnesium supplements primarily support muscle and systemic health; Magtein specifically targets neurological magnesium levels.
Brain magnesium levels play a critical role in synaptic plasticity — the brain’s ability to form and strengthen connections between neurons, underpinning learning, memory and cognitive flexibility. Research has shown Magtein supplementation supports improvements in cognitive function, memory and neurological health.
