iHerb Customer Reviews

Not L-Methyl folate anymore.

Posted by iHerb Customer on Oct 03, 2013 | Verified Purchase

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......

Thanks for your feedback!

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.

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!

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.
