Question: is 5 mthf the same as l methylfolate?
Answer: A manufacturer may have named their product as 5-MTHF and use the pure L form of methylfolate; however, one must inquire to be certain. Quatrefolic: What is this? This is a new form of methylfolate that uses glucosamine instead of calcium to bind the L-methylfolate. Quatrefolic is also a quality form of L-methylfolate.
