Not L-Methyl folate anymore.

Posted by Reviewer2298481 on Oct 03, 2013

This is different from the product description, the formula has now changed. It is not the L form anymore but a mixture of the L and D form. Not recommended as the D form is not biologically active and it is impossible to say how much fo the L form us present in the product. The Quatrefolic from this brand IS better but very expensive. Good quality alternatives are the Throne Research 5mg L-Methylfolate and Allergy Research Group Quatre Folate 500mcg of which I have used both and it is hard to say which one I prefer......

Product switched

Posted by Reviewer2373064 on Feb 10, 2013

I ordered this product which clearly states in the photo and on my receipt---L-Methylfolate. The product bottle I received looks identical except for there is no "L" before the Methylfolate. I have researched this product and learned that if the "L" is not on the label it is probably the "D" form of methyfolate which is inferior. I e-mailed I-Herb only to get a cut and paste response telling me how the product works. I will be returning this product but would like a response from the company addressing why I was sent a product different from what I ordered.

great product

After much research I began taking this supplement to compliment the SSRI's that I have been taking for years. It's a good product at a good price here at iherb!

Best Thing Since Sliced Bread

Posted by Reviewer1688301 on Feb 29, 2012

I've been having problems with mood my whole life but the last few years I've lost most of my concentration and a lot of long-term memory. The L-Methylfolate was prescribed for me and has given me back my life. I'm even healing faster than I have in many years. Awesome.
