Is Magnesium stearate NF tha same as magnesium stearate FCC?

Answer 1

The short answer is 'yes'. Here's the longer answer:

The NF (National Formulary) is a compendium of monographs and standards for excipients used in the manufacture of pharmaceuticals and dietary supplements. The FCC (Food Chemicals Codex) lists standards for ingredients used in food processing. Many ingredients are used both in foods and in pharmaceuticals/supplements, so the standards tend to be identical (or virtually identical). The same standards tend to apply around the world, so it is not unusual to see magnesium stearate labeled as Magnesium Stearate EP/BP/JP/USP/NF/FCC, meaning that it meets the standards of the European, British, Japanese and US pharmacopeias as well as the NF and FCC.
