Magnesium Citrate

Magnesium Citrate, E345, CAS no.7779-25-1, the Magnesium salt of Citric Acid, white powder, soluble in water. Magnesium Citrate manufacturing process via chemical synthesis, magnesium carbonate and citric acid as raw materials. Along with other citrics, such as Sodium Citrate, Calcium Citrate and Potassium Citrate, used as acidity regulator and preservative in food and beverage. Magnesium Citrate is also a source of magnesium used in food, beverage, and in nutritional supplement applications. Magnesium Citrate also used as a pore cleanser in skin care products and a fertilizer in plant food.

As an experienced Magnesium Citrate manufacturer and supplier, we has been supplying and exporting Magnesium Citrate for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.
