Magnesium is the fourth most abundant mineral in the human body and participates in over 300 enzymatic reactions, including energy metabolism, protein synthesis, nerve transmission, and muscle contraction. However, approximately 50% of adults do not consume enough magnesium. Chronic stress, high-sugar diets, and certain medications (such as proton pump inhibitors and diuretics) further exacerbate magnesium deficiency.
Different magnesium forms vary significantly in bioavailability and tissue distribution. Magnesium oxide has an absorption rate of only 4%, citrate ranges from 25% to 30%, and glycinate ranges from 40% to 50%. Magnesium L-Threonate stands out for its brain-targeting capability—research by MIT's Professor Guosong Liu confirms it is the only magnesium supplement that can effectively cross the blood-brain barrier.
Mechanistic studies show that threonic acid activates magnesium transporters (TRPM6/7) to efficiently deliver magnesium ions to the brain. Elevated brain magnesium levels modulate NMDA receptor function (preventing excitotoxicity), enhance synaptic plasticity (promoting long-term potentiation, LTP), and improve synaptic density—effects directly linked to learning, memory, and cognitive function.
Clinical trials show that daily supplementation of 1500-2000mg magnesium threonate for 8-12 weeks significantly improves cognitive function (executive function, working memory, attention) and sleep quality in middle-aged and older adults. Compared to other forms of magnesium, magnesium threonate demonstrates superior benefits for cognitive enhancement.
Dynas Group Hong Kong offers an Emotional & Cognitive Support formula (Magnesium L-Threonate + Zinc + Methylated B12 + L-Theanine) in the NeuroEndocrine Balance Series and a Daytime Cognitive & Relaxation formula (L-Theanine + GABA + Phosphatidylserine + Methylated B-Complex) in the Mind-Body Resilience Series. Both series support custom capsules and drops.
