L-Methylfolate 15 mg + Vitamin B12 with Methyl delivers a therapeutic blend of active folate and methylated B12 — formulated with next-generation Cerebrofolate™ for enhanced purity, absorption, and potency. This clinical-strength supplement is designed for those who require more intensive support for mood regulation, methylation efficiency, and homocysteine balance.

  • Neurological Support with Brain-Ready Folate
    Unlike standard folic acid, L-Methylfolate is fully bioactive and crosses the blood–brain barrier without conversion. This enables immediate support for neurotransmitter production, including serotonin, dopamine, and norepinephrine, which are vital for emotional stability and cognitive performance.
  • Cardiovascular & Detox Pathway Activation
    This formula aids in regulating homocysteine metabolism, a critical factor in both cardiovascular and neurological wellness. By supporting methylation pathways, it also assists with detoxification, DNA repair, and cellular resilience.
  • Genetically Optimized for MTHFR Variants
    With up to 50% of the population affected by MTHFR gene polymorphisms, this supplement is specifically engineered to bypass faulty enzyme pathways using Cerebrofolate™, ensuring reliable absorption and consistent therapeutic effect for those with impaired folate metabolism.

How much should you take?

This 15 mg dose is considered a therapeutic-strength formulation, commonly used for mood support, methylation optimization, and homocysteine regulation. It’s ideal for individuals under the care of a practitioner, especially those with MTHFR mutations or limited response to conventional antidepressants. Always speak with your healthcare provider to determine if this dose fits your needs.

Doctor-guided support

Visit our Dosage Information and Methylation Protocol pages to explore common practitioner strategies, including personalized dosing plans for those with COMT, MTR/MTRR, and VDR Taq genetic variants.

Capsule use & absorption

This supplement comes in a vegetarian capsule, which is not designed for splitting. However, the capsule can be opened and its contents emptied under the tongue to support enhanced absorption, especially for Hydroxy B12. This sublingual delivery is ideal for those with impaired B12 uptake or methylation concerns.

Additional considerations

Some individuals may benefit from starting at a lower dose and slowly increasing based on response and tolerance. If you’re new to methylated nutrients or unsure how your genetics may impact absorption, a gradual approach under medical supervision is strongly recommended.

Why L-Methylfolate Matters

L-Methylfolate is the only form of folate that crosses the blood–brain barrier. It plays a direct role in neurotransmitter production (including serotonin, dopamine, and norepinephrine), mood regulation, DNA synthesis, and homocysteine metabolism — all essential for cognitive and emotional health. For individuals with MTHFR gene mutations, this active form bypasses the genetic block in folic acid conversion, offering reliable bioavailability.

Key Scientific Findings

  • 5-MTHF is the predominant form of folate in human circulation¹
  • Clinical research shows 15 mg methylfolate + SSRI is the most effective dose for mood improvement²
  • L-Methylfolate is the only folate form proven to cross the blood–brain barrier³
  • Cerebrofolate™ offers superior purity and potency compared to other 5-MTHF sources²⁰
  • Shown to support immune function, cardiovascular health, and prenatal development⁶⁻⁸

Clinical Research Link

This formula is supported by multiple peer-reviewed studies showing the critical relationship between L-Methylfolate, MTHFR polymorphisms, mood regulation, and cognitive decline. One key double-blind trial demonstrated that 15 mg L-Methylfolate improved depression outcomes when used alongside SSRIs.

Frequently Asked Question

Check out our Dosage page to learn what some doctors are saying. And consider reviewing our Methylation Protocol page as one example of how someone could start taking the active methylation nutrients.
This natural, mood-enhancing supplement provides a high dose of L-Methylfolate 15mg along with vitamin B12 with methyl at 1000 mcg, which supports methylation processes in the body. It may be beneficial for individuals with specific health concerns, genetic challenges or nutritional needs requiring higher levels of these nutrients.
A therapeutic high-dose of bioactive L-methylfolate is often considered 7.5 mg - 15mg in a supplement uniquely formulated with an internationally-patented methylfolate brand. L-Methylfolate 15mg + active vitamin B12 with methyl 1000 mcg & inositol.
One of the most common other nutrients to consider when supplementing the methylation cycle is the proper form of B12. There are 3 different types of B12 that are considered very beneficial to the body (hydroxy B12, vitamin B12 with methyl or adenosylcobalamin). Many automatically think that if you have an MTHFR defect, then you need the form of B12 called vitamin B12 with methyl, but that is simply NOT true. It’s important to realize that the MTHFR status does not necessarily determine the type of B12 that’s best for you, instead it’s the status of genes like COMT, MTR, MTRR as well as VDR Taq. It is true that L-methylfolate and vitamin B12 with methyl work together synergistically along the methylation cycle pathway, but that doesn’t necessarily mean that if you tolerate L-methylfolate well you’ll also need, want or tolerate vitamin B12 with methyl well (even if that’s what most doctors, nutritionists, etc. are currently saying right now). It seems there may be a general lack of education available to most doctors about the different forms of B12 and what those forms are as well as how they get converted within the body and what each is most beneficial for (not to mention which set of genes or genetic mutations could benefit most from which B12 type). So do your homework when it comes to B12 to see which you may tolerate best. The most common form of B12 that you’ll find everywhere is cyanocobalamin and it is not very active or beneficial to the body because the absorption rate is fairly low, that’s because the body has to convert it first into hydroxy B12, and from there the hydroxy B12 has to be converted into both adenosylcobalamin and vitamin B12 with methyl. But if the body has genetic mutations then these conversions don’t happen well at all and the effect is the body does not get the absorption or use of the nutrient.
L-Methylfolate 15mg + Vitamin B12 with Methyl is a supplement that combines L-Methylfolate, the active form of folate, with an active form of vitamin B12 for a professional-strength, mood-enhancing supplement.
You'll find our MTHFR Newbies page is very helpful as well. It's got some great tips for folks who haven't done much study on what to do if you have an MTHFR variant.
The most important thing to realize is that blood tests for B12 are highly inaccurate at detecting actual cellular levels of B12 (meaning the B12 that’s available for the cells to use). Studies have shown that people can have high or normal B12 levels in the blood and actually show virtually no B12 in the spinal fluid, meaning the B12 is not being transported from the blood stream into the cells where it should be absorbed and used.
If you have your 23andme genetic test results, you can use those to help guide you as you try the specific B12 forms to see how they do for you. You’ll notice below that, according to Dr. Amy Yasko, the most well tolerated active form of B12 for folks seems to be Hydroxy B12. Every single one of the genetic combinations she lists below should be able to tolerate B12 in the form of Hydroxy B12 (and this is why our methylation protocol suggests Hydroxy B12 as the B12 form to begin with):

Methyl-Life® 5 Methylfolate 5 mg – Clinically-Backed Support for Cognitive Health, Methylation & Mood Balance

Methyl-Life® 5 Methylfolate 5 mg delivers a moderate-strength dose of bioactive folate — also known as 5-MTHF or L-Methylfolate — the most absorbable form of folate for the body. Specially formulated for individuals with MTHFR gene variants, this supplement supports healthy methylation, cardiovascular function, brain health, and neurotransmitter production without relying on the body's ability to convert synthetic folic acid.

If you struggle with folate absorption, mental fatigue, mood imbalances, or elevated homocysteine levels, this supplement may help you experience the benefits of folate faster and more efficiently.

Understanding the MTHFR Mutation and Folate Deficiency

Many people dealing with fatigue, brain fog, or mood imbalances don’t realize a genetic mutation could be interfering with how their body processes folate. The MTHFR gene plays a crucial role in converting folic acid into L-Methylfolate, the active form the body actually uses.

When MTHFR is mutated, this conversion becomes impaired.
