## Description

Folate 666 MCG DFE (Metafolin 400 MCG) 100 Tablets

Review: Quality supplement, delivers on its promise - I ordered these because I have two family members with the MTHFR gene defect (which prevents absorption/utilization of the standard forms of iron). This supplement is a form of iron which has been converted so that people with the MTHFR defect can utilize it (my lay understanding, as per a health professional's recommendation to seek out this form of iron). I researched numerous brands and found Solgar to have both an excellent reputation for providing exactly what they advertise, in packaging that protects the products integrity, at a reasonable price. They have met all of those expectations, and both family members have seen their health issues diminish greatly, experiencing better iron counts, less fatigue, and noticeably improved energy and focus. Do your own research and, of course, consult your own health pros. One of my relatives did experience some constipation at a particular dosage (best dosage will vary per person depending on a variety of factors) but they adjusted the timing of the dosing and that problem went away. Giving this five stars, as this worked for us exactly as it should.

## Questions & Answers

**Q: One picture shows folate 666 mgc dfe and in small print underneath metafolin 400 mcg and another shows only folate 400 mcg...are they the same?**

**Q: How long the expiration date takes? I´d like to estimate this because I live in Brazil but need to buy it for up to 2016,since it´s a long treatment**
A: The expiration date on my bottle is 9/2017.

**Q: How much mannitol is in one tablet?**
A: Nowhere on the bottle does it say anything about Mannitol.  
It only contains Folate
I do see on the online photo of the bottle that after it says Folate 666MCG DFE 
in parentheses it says (Metafolin 400NCG) tablets

**Q: How long the expiration date takes?**
A: MIne never lasts until the exp date.  You'll have to google it or do some other research.
