Review: 'Through the Shadowlands’ describes Julie Rehmeyer's ME/CFS Odyssey
I should note at the outset that this review is based on an audio version of the galleys and the epilogue from the finished work. Julie Rehmeyer sent me the final version as a PDF, but for some reason my text to voice software (Kurzweil) had issues with it. I understand that it is...

    Hello,

    I have a question about the Thorne Basic Bcomplex. The one I have used untill now has Ca-5-methyltetrahydrofolate. I wanted to order new Thorne Basic Bcomplex, but now it says 5 MTHF (quatrefolic) on the bottle. Is this both the same ingredient, but just another name?

    Thank you very much for your answers

    Greetings, Jodie

    Technically, they're not the same, but should have comparable efficacy. If you're really sensitive to the amount of folate, you may notice a difference, but really the differences are more technical than practical.

    Just for completeness, here's the technical part. Ca-5-methyltetrahydrofolate or Metafolin is the calcium salt of levomefolic acid (the thing we care about), whereas Quatrefolic is the glucosamine salt. So they both contain the same substance, just bound to a different carrier.

    Just curious! - I thought I had read somewhere that unless "L" or "6S" in the label that it is the racemic version and contains both the "6S" (active) and the "6R" (inactive) isomers. I'm not sure if side effects or absorption issues are associated with the "6R" isomer or not.

    Maybe someone can answer this???

    I would be a little surprised if "Thorne" used what might be considered as a less active product though!

    Thank you, you're right, I should have been more careful about that. The "L" or "6S" is crucial. I can't seem to find a picture of the old bottle, but I'm guessing it says Ca-L-5-methyltetrahydrofolate. If it's Ca-5 then some portion of it could be inactive like you said.

    Quatrefolic is a brand name for "L-5-Methyltetrahydrofolic Acid, Glucosamine Salt", so if it says Quatrefolic, you're good to go. Similar thing for Metafolin.

    There's a lot more information here: http://mthfr.net/l-methylfolate-methylfolate-5-mthf/2012/04/05/
