Clarification for Reviewer1387214 From Argentina
Posted by Reviewer2798647 on Jul 29, 2012
I just wanted to clarify the folate pathway for the reviewer from Argentina. Folinic acid is a form of folate which is present prior to the MTHFr enzyme, which is the enzyme that forms the nervous system active methylfolate (5MTHF). Many people have a weakness at this enzyme and have sub-optimal production of methylfolate. Therefore, this product is actually the best way to make up the shortfall of methylfolate as it is already in the active CNS preferred form and can cross the blood-brain-barrier. Folinic acid can never fill the shortfall. Also, in a B12 dependant action, methylfolate is converted to tetra-hydro-folate (THF) so methylfolate is not "a path of no return". Hope that helps. Also, my review is based on the efficacy of methylfolate, which I am very low on (I had it tested via a specialist lab).

Capsules are small and good to swallow.
It don't like

The best way to take folate is the folinic acid, because the QuatreActive folate is a path without return in the metabolic process.

Been using for 12 months great product
Cost effective - seems to get the job done

We have used this for a few months now, without any problems. The capsule size is small, so better for kids. We use the 500ug twice a day. This appears to be a very cost effective buy - fraction of the cost of the Thorne 5MTHF product. Apart from needing to take 2 capsules, we don't notice any difference.
