L-5-Methyltetrahydrofolate Calcium

L-5-Methyltetrahydrofolate calcium (levomefolate calcium) is the calcium salt of (6S)-5-methyltetrahydrofolic acid, the naturally occurring reduced form of folate (vitamin B9) found in foods, supplied by Nustras as a fine powder and used as a direct source of methylated folate for supplements and fortification. Folate is an essential vitamin and a coenzyme in one-carbon transfer reactions.

It is formulated into vitamin and multivitamin supplements in tablet, capsule and powder form, into prenatal and B-complex products, into vitamin premixes, into fortified foods and beverages, and into medical nutrition formulations.

The material is a fine powder with CAS number 151533-22-1, molecular formula C20H23CaN7O6 and a molecular weight of 497.5. Assay, calcium content, related substances, loss on drying and the proportion of the (6S) isomer are standardised to specification; identity and assay are confirmed by HPLC, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies L-5-methyltetrahydrofolate calcium in bulk commercial quantities, in sealed packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. L-5-Methyltetrahydrofolate calcium is a permitted folate source in major supplement and food markets; buyers confirm the permitted level and folate declaration for their application.
