Product Overview

  • (6S)-5-Methyltetrahydrofolic Acid Glucosamine Salt
  • 4th Generation Folic Acid Technology
  • The More Stable, More Bioavailable Form of Folate
  • Quatrefolic
  • Dietary Supplement

Methyl Folate ((6S)-5-methyltetrahydrofolic acid or (6S)-5-MTHF) is the most biologically active form of folic acid. Quatrefolic is the 4th generation development in folate delivery. With certain inherited errors in metabolism and under a variety of physiologic stresses, the transformation of folic acid into the active form of folate either does not properly take place or is inadequate. Unlike folic acid, this form of folate can cross the blood-brain barrier. Methyl Folate is needed to support cardiovascular and neurologic health and proper cell division.

Health Claim: Healthful diets with adequate folic acid may reduce a woman's risk of having a child with certain brain or spinal cord defects.

Suggested Use

Take 1 capsule per day with food or as directed by your qualified healthcare professional.

Other Ingredients

Cellulose and magnesium stearate (vegetable source). Capsule consists of gelatin.

No wheat, not gluten, no soybeans, no dairy, no egg, no fish/shellfish, no peanuts/tree nuts.


Note: The elderly should frequently check B12 status when taking folic acid as folic acid may mask pernicious anemia. If you have a medical condition, are pregnant, lactating, trying to conceive, under the age of 18, or taking medications (especially antiepileptic and chemotherapy medications), consult your healthcare professional before using this product.

Keep out of the reach of children.

Works as well as other brand - No stomach upset

Posted by Reviewer1660870 on Jun 19, 2013

I've had CFS for many years. I tried Solgar's equivalent product Metafolin. It worked but gave me an upset stomach. I can't afford an upset stomach as I have IBS symptoms so I tried this. This does the same thing without the stomach upset. What does it do? It changes my perception of, and tolerance to cold. I don't feel the cold as much basically. The cold used to always feel as if it was going into the bone but not anymore. It affected my brain fog in a subtle way. It didn't remove it (B12 patches did) but it improved my ability to focus my attention and eyes on one spot. Before taking it I'd be unable to focus and my attention would sort of be constantly hazy and scattered within the brain fog.

Methyl Folate even a kid can swallow

Posted by cot477 on Jun 24, 2013

These capsules are itty bitty and my child swallows them easily. Methyl Folate, at the low 400 dosage, is important for people with the genetic MTHFR issue. This is a great product.

helps with genetic defect

Posted by 5407507132661655598 on Feb 19, 2015

I take this because of my genetic inability to process folic acid. I notice my mood is much improved when I take 2 a day.

I was first taking one tiny capsule per day, bur just recently I came across MTHFR issuee and that I might have a problem with it, so I took 10 of these (4 mg) two days in a row (that's how much I had left) just to try if it will do anything.. and wow, I was energetic for 5 days and had no problem waking up in the morning, also I was drinking heavily that weekend and didn't have so bad hangover as usual. I usually need to sleep for 12 hours (adrenal fatigue), but during that time I didn't sleep as much. I slept for 9 hours. After 5 days effects subsided, so I will be taking much more of these.
