    Overview

    Aquamin Mg is a marine-source magnesium hydroxide derived from purified Atlantic seawater, providing magnesium alongside ~74 trace minerals.

    Mechanism & Function

    Mechanism of Action

    Provides magnesium for ATP-binding and enzymatic function; trace minerals support bone matrix and joint cartilage.

    Physiological Role

    Used in clean-label sports formulas; modest evidence for joint comfort beyond Mg alone.

    Primary Pathways

    Intestinal Mg absorptionMg²⁺-ATPase enzyme co-factorBone matrix mineralisationCartilage co-factor support

    Performance / Health Relevance

    Manufacturer-funded RCTs show modest joint comfort improvements; magnesium component supports recovery.

    Magnesium Oxide

    In patients with marked intestinal malabsorption (ileal resection), magnesium oxide showed lower absorption compared with a magnesium diglycinate chelate in a crossover study (7815675).
