Jarrow Formulas Methyl Folate 400 mcg Review

Name: Jarrow Formulas Methyl Folate 400 mcg
Brand: Jarrow Formulas
Availability: InStock

6.2/10SAC Product Score™

Jarrow's methyl folate is the value entry into the 5-MTHF category: 400 mcg of (6S)-5-MTHF in a vegan capsule at roughly $9. If you have already decided you want active methylfolate and want to spend the least, this is a reasonable pick at the correct dose. It ranks below the premium methylfolate options on testing transparency — Jarrow carries non-GMO/vegan claims but not the third-party seals of Pure Encapsulations or Thorne — and below all folic acid picks because, once again, the active form has no NTD-prevention trials. Cheap methylfolate is still methylfolate: fine for the right buyer, not the evidence-based default.

▸ THE SCORE

How we built the SAC Product Score™ — 6.2/10

NTD-Prevention Evidence30%4.5/10

Methylfolate has no NTD-prevention trial data, and a budget product does nothing to change that evidence gap.

Form & Bioavailability20%8/10

(6S)-5-MTHF is the active, conversion-free form; bioavailability is comparable to premium methylfolate.

Dose Appropriateness20%7/10

400 mcg matches the standard folate target, an appropriate dose for the category.

Third-Party Testing20%6/10

Non-GMO, vegan and gluten-free, but no independent USP/NSF or explicit third-party potency verification.

Value10%6.5/10

Around $9 for 60 capsules — cheap for methylfolate, though still far above folic acid per dose.

▸ SPECS

The product at a glance

Form: (6S)-5-MTHF veggie capsule
Dose: 400 mcg methylfolate
Count: 60 veggie capsules
Testing / Certification: Non-GMO, Vegan, Gluten Free
Cost per dose: ~$0.15 per capsule

▸ TRUTH CHECK

Marketing claims vs. reality

Verified

“(6S)-5-MTHF is the biologically active folate form”

(6S)-5-methyltetrahydrofolate is the naturally occurring active isomer used directly in one-carbon metabolism without conversion (PMID 24494987).

Partial

“Budget methylfolate works as well as premium brands”

The active form is the same, but without third-party testing there is less independent assurance of potency and purity than premium competitors provide.

▸ THE DEEP DIVE

What our test actually found

01Correct isomer, correct dose, thinner testing

Jarrow delivers the right active form at the right dose, but the absence of explicit third-party verification is the main gap versus pricier methylfolate.

02Cheap doesn't fix the evidence problem

Lowering the price of methylfolate makes it more accessible, but it is still a form without NTD-prevention trials — so it does not become the evidence-based default just by being affordable.

▸ THE TRADE-OFFS

Pros & cons, no sugar-coating

Pros

Lowest-cost route into active methylfolate
Correct (6S)-5-MTHF isomer at the standard 400 mcg dose
Vegan, non-GMO, gluten-free capsule
Reasonable everyday value within its category
Simple single-ingredient design

Cons

No independent third-party testing seal
Active form still lacks NTD-prevention evidence

▸ THE BOTTOM LINE

Fine budget methylfolate, still not the default

If you want active methylfolate and want to spend the least, Jarrow is a sensible pick at the right dose. But the thinner testing transparency and the same evidence gap as all methylfolate keep it in the lower half. For proven prenatal protection at even lower cost, a folic acid tablet remains the smarter buy.
