MAG Complex: Multi-Salt Magnesium, Potassium Citrate, P5P and Chlorella vulgaris — An Ingredient-Based Narrative Review of the Formulation Rationale and Clinical Evidence for Nerve, Muscle, Cardiovascular, Metabolic and Neuropsychological Indications
Abstract
Magnesium is the second most abundant intracellular cation in the human body and the obligatory cofactor of more than 600 enzymatic systems governing ATP-dependent metabolism, oxidative phosphorylation, glycolysis, protein synthesis, membrane transport, neuromuscular transmission and vascular tone. Despite this physiological centrality, an estimated one-third of the global adult population fails to meet the dietary recommended intake for magnesium, and subclinical inadequacy is widespread and frequently under-detected because serum magnesium is tightly homeostatically defended and represents less than 1 % of total-body stores. MAG Complex is a multi-component nutraceutical combining five magnesium salts — trimagnesium phosphate, chloride, gluconate, oxide and aspartate — with potassium citrate, pyridoxal-5′-phosphate (P5P, the active coenzyme form of vitamin B6) and small quantities of Chlorella vulgaris dried powder. It is designed to balance elemental-magnesium density against solubility and gastrointestinal tolerability, supply complementary electrolytes, alkalinise through the citrate anion and deliver a nutrient-dense microalgal matrix. This article is an ingredient-based narrative review summarising each constituent's physiological role, appraising evidence by Oxford Centre for Evidence-Based Medicine tier, deriving FSSAI-approved structure–function wording, and outlining product-specific research gaps. Strongest evidence supports magnesium's role in maintaining normal…
