Science & Research

Verifiable Science

Supports optimal brain magnesium levels to promote cognitive function, learning ability and working memory. Animal research suggests that magnesium-l-threonate may promote synaptic plasticity and density in the regions of the hippocampus correlated with learning and memory.1 In a clinical trial of 44 participants aged 50-70, magnesium l-threonate (Magtein™) provided significant support for cognitive processing speed, executive function and overall cognitive ability after only 6 weeks.2 An in vitro study demonstrated that PhytoMemory, a blend of blueberry, strawberry and spinach extracts, maintained healthy activity of prolyl endopeptidase (PEP), a protein involved in learning and memory.3 Consumption of blueberries, strawberries and spinach has been associated with brain health in clinical studies.4‡
