I had been getting the Source Naturals brand of Metafolin (biologically active form of folic acid) from a particular vitamin/supplement web site, but within the past few months it has “disappeared”. The only reference I can find now on the Source Naturals web site for Metafolin is the original press release document http://www.sourcenaturals.com/articles/5039/ (can no longer find the actual product representation on the site). It appears that maybe Metafolin has been replaced by MegaFolinic ?? http://www.sourcenaturals.com/products/GP1872/. This “new” product doesn’t look exactly the same as the original Metafolin (L-methylfolate). Did Merck “pull the plug” on Metafolin?
