300mg MAGNESIUM per serving
Applied Nutrition Tri-Magnesium is a powder-format magnesium supplement delivering 300mg of elemental magnesium per 4g serving from three distinct magnesium forms. Each serving provides magnesium from bisglycinate (1000mg compound, yielding 200mg elemental), magnesium taurate (417mg compound, yielding 50mg elemental) and magnesium citrate (324mg compound, yielding 50mg elemental). The 200g tub provides 50 servings at 6kcal per serving.
Magnesium bisglycinate at 200mg elemental is the dominant form in this formula. The glycinate chelate resists dissociation in the gastrointestinal tract, reaching the intestinal wall intact for absorption via amino acid transporters — achieving higher bioavailability than inorganic forms such as oxide or carbonate. Magnesium taurate provides a taurine-conjugated form that has been researched for cardiovascular tissue support due to taurine's role in cardiac cell function. Magnesium citrate provides a third pathway for absorption with good solubility in water, reducing the gastrointestinal discomfort associated with high-dose magnesium oxide supplementation.
Magnesium at 300mg (80% NRV) is EFSA-authorised to contribute to normal muscle function, a reduction of tiredness and fatigue, normal protein synthesis, the normal functioning of the nervous system, the maintenance of normal bones and teeth, and normal energy-yielding metabolism — six authorised claims in one mineral. The powder format allows flexible dosing: half a serving at 150mg elemental magnesium can be taken in the morning and half at night to spread absorption across the day.
Tri-Magnesium suits athletes with high sweat-rate training loads, those supplementing for sleep quality, individuals with muscle cramping or fatigue and anyone who does not tolerate single-form magnesium supplements. It is not flavoured.
Capsule alternative: Efectiv Nutrition Magnesium Bisglycinate Blend 90 Caps (100mg elemental from 3 forms) delivers 100mg elemental magnesium from three forms in a no-mix capsule format.
