Inessa Calcium & Magnesium is a bioactive marine mineral complex designed to support bone health, muscle function, and energy levels. Ethically sourced from pristine Atlantic waters, it delivers a well-balanced blend of seaweed-derived calcium and seawater magnesium in their natural, highly absorbable forms.
Calcium is essential for maintaining strong bones and teeth, while magnesium supports muscle function and helps reduce tiredness and fatigue. This formula is particularly beneficial for those with increased calcium needs, such as postmenopausal women. Free from chemical purification and tested for contaminants, it provides a clean, sustainable source of these key minerals.
Designed to complement a daily multivitamin, Inessa Calcium & Magnesium fills nutritional gaps with clinically relevant doses in an easy-to-take format.
Inessa creates industry-leading, clinical-grade nutritional supplements grounded in the latest scientific research. Founded by nutritional therapist Liza Moragy, the brand emerged from her personal journey—after managing an autoimmune condition with diet and supplements, she recognised the need for high-quality, research-backed formulation that simplify supplementation. Today, Inessa is dedicated to delivering effective, optimally dosed formulas, making wellness both convenient and accessible.
