5-MTHF Extrafolate-S® 15mg
90 CAPS
Supports normal healthy mood, cardio and nerve function.*
L-Methylfolate is important for normal production of serotonin, norepinephrine and dopamine, and is essential for converting homocysteine to methionine.*
Metabolic Maintenance has always used 5-MTHF made by Gnosis S.p.A. in Italy. We have recently decided to include their registered trademark “Extrafolate-S®” in the name of our stand-alone 5-MTHF products. We have made this adjustment on our website, although our product labels will take a few weeks to reflect this change. Extrafolate-S® is pure S isomer L-5-Methyltetrahydrofolate, calcium salt.
Our products have not changed. This name change was made only to acknowledge our supplier and clarify the source of our 5-MTHF.
