iHerb Customer Reviews

This product regulates my blood cell size so my organs can heal properly.

Posted by iHerb Customer on February 14 2017 | Verified Purchase

I was diagnosed with ulcerative colitis several years ago and put on prescription medications for it, supposedly til forever. I tried going off the medications myself once, only to relapse and lose hope. However, still being convinced I wouldn't take these drugs for my whole life and praying about other options, I finally saw a naturopathic doctor who listened to an extensive explanation of my situation, ran several detailed blood tests, and recommended this and a few other supplements. He explained that part of why my colon was not healing was because (as he discovered from one of the blood tests) my red blood cells were too big. This meant they couldn't get down into the little blood vessels with both their own large size and the sufficient oxygen and nutrients necessary to heal my colon. He said that the MTHF will help to regulate my red blood cell size so they shrink a bit, back to normal size range, and then begin the natural healing process. After gradually weaning myself off the prescription medication and beginning the supplement routine, I have been completely drug free and taking the supplements for over three years now with no relapses. Praise God!

Cost effective - seems to get the job done

Posted by iHerb Customer on April 22 2016 | Verified Purchase

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.

Thanks for your feedback!

Clarification for Reviewer1387214 From Argentina

Posted by iHerb Customer on May 12 2012 | Verified Purchase

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).

Thanks for your feedback!
