Magnesium Citrate Nonahydrate Powder (Mg >16%)

Magnesium citrate nonahydrate is the tribasic magnesium salt of citric acid crystallised with nine molecules of water, carrying three magnesium ions for every two citrate anions. Nustras supplies it as a white powder, in standard, micronised and granular grades, as a magnesium source for dietary supplements and fortified foods.

It is formulated into magnesium tablets, capsules and powders; into effervescent and drink-mix formats, where its water solubility is useful; into mineral premixes for fortified beverages and foods; and into combination products with calcium, zinc or vitamin D.

Magnesium citrate nonahydrate is supplied as a white, odourless powder (CAS 153531-96-5, molecular formula C12H28Mg3O23, molecular weight 613.25). Magnesium content, water content and particle size are standardised to specification; identity is confirmed by magnesium and citrate tests and assay by complexometric titration. Heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies magnesium citrate nonahydrate powder in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Magnesium citrate is an accepted food additive and supplement mineral source in major markets; buyers confirm the elemental-magnesium contribution, hydrate form and permitted level for their application.
