Review: I started taking Thorne 5-MTHF after genetic testing revealed I have MTHFR mutations that affect my body's ability to process regular folic acid. My functional medicine doctor specifically recommended this Thorne product for its superior quality and bioavailable form of folate, and I've been consistently impressed with both the product quality and the health improvements I've experienced. What sets this supplement apart is the methylated form of folate, which bypasses the genetic conversion issues that affect many people. Within a few weeks of starting this supplement, I noticed improvements in my energy levels and overall sense of well-being that I hadn't experienced with regular B-vitamin complexes. My follow-up lab work showed significant improvement in my homocysteine levels, which was exactly what my doctor was hoping to achieve. The quality control and purity that Thorne is known for is evident in this product. The capsules are clean with no unnecessary fillers or artificial ingredients, and I've experienced no digestive upset or side effects. The dosing is appropriate and easy to incorporate into my daily supplement routine. The cardiovascular and neurological support benefits align perfectly with what my healthcare provider explained about methylfolate's role in cellular function. I feel confident knowing this is supporting my body's methylation processes that are crucial for so many aspects of health. The packaging protects the supplements well, and the expiration dates are always well into the future, indicating proper storage and handling. Highly recommend for anyone needing bioavailable folate, especially those with MTHFR mutations - excellent quality from a trusted brand that healthcare providers consistently recommend.

## Questions & Answers

**Q: What's the difference between this product and just a plain folate product?**
A: This product is methylated. That means that those individuals who have the genetic defect MTHFR will be able to use the folate and other B vitamins. These will be absorbed into their systems to keep homocysteine levels low among other benefits. If you don't have that defect, you do not need the methylation. Some of us will use it as long as we live.

**Q: Hi,  Can't purchase without viewing the Ingredient Label.  Could you post an image? Thank You.**
A: Hello MariaThorne Research 5-MTHF , on one capsule contains:Folate (as L-5-Methyltetrahydrofolate*) 1 mg.Other Ingredients: Microcrystalline Cellulose, Hypromellose (derived from cellulose) capsule, Leucine, Silicon Dioxide.  Until we can upload it on the list, here is a capture of it: http://ecx.images-amazon.com/images/I/81uj6EAFjZL._SL1500_.jpg The Febstore Team

**Q: What is the difference, if any, between Methyltetrahydrofolate and Methylfolate?**
A: The 5-MTHF, also known as L-methyl folate, methyltetrahydrofolate The brand is ExtraFolate-S, by Gnosis.
•        It’s the active form of folate and only the active L (aka S) form (not a racemic mixture of R and S)
•        Stabilized by calcium
•        The extraction process separates the active (S, aka L) isomer without using a solvent
•        Created by Gnosis, the technology leader in active folate supplementation
•        Contains only the L isomer (the active isomer) of 5-MTHF

Thorne's other formulas, such as the Methyl-Guard use a different form, it is still 5- MTHF, methyl folate, methyltetrahydrofolate but the brand is Quatrefolic, also provided by Gnosis. 
•        It’s the active form of folate and only the active L (aka S) form (not a racemic mixture of R and S)
•        Stabilized by glucosamine (not derived from shellfish).
•        This form passes the gastric barrier and is absorbed mainly in the small intestine by a carrier-mediated mechanism, which ensures higher folate uptake 
•        Created by Gnosis, the technology leader in active folate supplementation
•        Contains only the active L-isomer form of 5-MTHF
The difference is that one is a calcium salt and the other is a glucosamine salt. Overall, both are highly absorbable and providing 5-MTHF.

**Q: Newest bottles (November 2014) are smaller as are the capsules, much smaller. The product info looks the same. Is this the same stuff?**
A: Yes
