A water-free form of magnesium citrate, characterized by high purity and low moisture content (≤2% water), enhancing stability in dry formulations. It provides magnesium in a bioavailable, citrate-bound form, supporting muscle relaxation, nerve function, and bone health, while acting as an osmotic laxative for occasional constipation. Ideal for tablets, capsules, or dry blends requiring moisture resistance, it offers consistent magnesium delivery (11.2% elemental magnesium) without crystalline water, ensuring shelf-life integrity in humid environments.

Magnesium citrate anhydrous offers several notable benefits:
1.High Bioavailability: As an anhydrous form, it lacks water molecules, which enhances its solubility and absorption in the body. This allows for more efficient delivery of magnesium to cells, supporting optimal physiological function.
2.Gastrointestinal Health Support: It acts as a natural osmotic laxative, drawing water into the intestines to soften stools and promote regular bowel movements. This makes it a popular choice for relieving occasional constipation in a gentle manner.
3.Muscle and Nerve Function Enhancement: Essential for muscle relaxation and nerve signal transmission, magnesium citrate anhydrous helps prevent muscle cramps, spasms, and supports a healthy nervous system, reducing feelings of anxiety and stress.
4.Bone Health Maintenance: Contributes to bone mineral density by assisting in the metabolism of calcium and other key minerals. Regular intake can help strengthen bones and reduce the risk of osteoporosis over time.
Its anhydrous nature means it has no water molecules bound to its structure, resulting in high solubility. This property allows for rapid dissolution in the digestive tract, enabling a higher percentage of magnesium to be absorbed by the body and reach target cells efficiently.
Free from water, magnesium citrate anhydrous offers excellent stability in various supplement formulations, such as tablets, capsules, and powders. This stability ensures consistent magnesium content over the product's shelf life, guaranteeing reliable supplementation.
Besides being a rich source of magnesium, it acts as a natural osmotic agent, promoting healthy bowel function. This dual action not only provides the essential mineral but also helps prevent the constipation often associated with magnesium supplementation, making it a more user - friendly option.
