Calcium Magnesium Citrate Purified Powder

Jost Code: 2200

Calcium Magnesium Citrate can be used as a dietary supplement and as a nutrient.

Jost R&D developed a proprietary process to create a unique product: Ca2 MgCitrate which will not harden in water solution and gives the correct ratio of Ca: Mg of 2:1 — the same ratio as the recommended daily requirement. Calcium Magnesium Citrate Pentahydrate provides 14% calcium and 4.2% magnesium per unit dose on an “as is” basis, delivering 140mg of calcium and 42mg of magnesium per gram of Calcium Magnesium Citrate Pentahydrate used in a formulation.

Code 2200, Purified Powder is beneficial to customers that desire aqueous suspensions of Ca and Mg with excellent mouth feel and unmatched suspension stability. Jost’s calcium magnesium citrate co-salt stays in suspension and therefore alleviates solidification, hardening and flowability issues, even over an extended period of time.

Calcium is vital for strong bone and teeth formation. It also helps to maintain a regular heartbeat and transmission of nerve impulses. Magnesium plays a vital role in regulating the neuromuscular activity of the heart, converts blood sugar to energy and is necessary for proper calcium and vitamin C metabolism. Product specifications, SDSs and certifications are available under Additional Information.
