1. Product Overview
Magnesium Citrate Anhydrous is a high-quality mineral supplement material characterized by its high magnesium content and excellent solubility compared to other magnesium forms. As an anhydrous salt, it contains significantly more elemental magnesium than the nonahydrate form, making it a preferred choice for manufacturers aiming for high-potency formulations in small capsule or tablet sizes.
At Xi’an SR Bio-Engineering, we provide premium Magnesium Citrate Anhydrous with strictly controlled heavy metal levels and consistent particle size distribution, ideal for diverse industrial applications.
