Key Ingredients

Two finished forms. Both ready the moment they hit your bloodstream.

🧬 L-Methylfolate (L-5-MTHF Calcium Salt) — 15 mg

The active, finished form of folate. No conversion required. 10× more absorbable than folic acid in MTHFR-variant cells.

💊 Methylcobalamin (Active B12) — 1,000 mcg

The bioidentical, pre-activated form of B12 your body uses directly. Supports the methylation cycle, healthy nerve function, and steady cellular energy.

Health Benefits

What complete methylation support means for how you feel and perform.

Mood support

Folate supports the body's natural production of key neurotransmitters that influence mood, including serotonin, dopamine, and norepinephrine.

Mental focus and cognitive function

Folate supports the brain's energy metabolism and the cellular pathways behind clear thinking.

Cellular energy

Methylation is foundational to mitochondrial function and the body's natural ATP production.

Hormone metabolism

Folate supports the methylation pathways involved in the body's natural processing of hormones.

Healthy inflammatory response

Methylation is involved in the body's normal inflammatory signaling pathways.

Heart health

Folate supports the body's normal homocysteine metabolism, which is involved in healthy cardiovascular function.

Ideal For

Who this formula is built for.

The mom running on fumes.

Carrying mental load, snapping at people you love, and never quite catching up on rest — even when you sleep.

The high-performer who can't focus anymore.

You used to think clearly. Now the words don't come, the afternoons drag, and you wonder when your brain stopped working the way it used to.

The person who's tried everything.

Folic acid, B-complex, multivitamins, adaptogens — none of it moved the needle. You're wondering if you're broken or if you've just been taking the wrong thing.

The one whose family has "the mental health stuff."

Anxiety, depression, mood swings, ADHD — patterns that run in the family. You've started to wonder if there's a common thread.

The clean eater who still feels off.

You eat the leafy greens. You take the prenatal. You do the cold plunge. And somehow your energy, mood, and focus still don't match the effort.

Anyone who's been told they have an MTHFR variant.

Or anyone who suspects they might. (1 in 2 adults carry it. Most never get tested.)

L-Methylfolate ™— Active 5-MTHF + Methyl B12

America's #1 methylfolate. 15 mg of active 5-MTHF paired with methyl B12 — the two pre-converted forms your body actually uses for steady mood, sharp focus, and lasting energy. No conversion required.
  • Already activated. Already absorbable. Most folate is folic acid — your body has to convert it. 5-MTHF is the active form, ready the moment it hits your bloodstream.

  • Folate and B12 work as a pair. Active folate without active B12 stalls. This formula delivers both in their finished forms.

  • A clinical 15 mg dose. Not a sprinkle. The dose published research actually uses.

Frequently Asked Questions

Is this product safe if I'm pregnant or breastfeeding?

L-Methylfolate is the form many practitioners recommend during pregnancy and breastfeeding — but every pregnancy is different. Please share this product with your OB/GYN or midwife before starting, especially if you are taking a separate prenatal vitamin.
Are there any known side effects?
Most people tolerate L-Methylfolate well. A small number of people new to methylation support report transient symptoms in the first week (mild headache, irritability, or increased energy at night). Lowering the dose or taking it earlier in the day usually resolves it. If symptoms persist, stop the product and consult your practitioner.
Can this supplement interact with medications?
L-Methylfolate can interact with certain medications, including methotrexate, anticonvulsants, and some SSRIs. If you are currently on a prescription, please discuss with your prescribing provider before starting any new methylation support.
What is L-Methylfolate and how is it different from folic acid?
Folic acid is a synthetic form of folate that your liver has to convert into the active form (5-MTHF) before your body can use it. L-Methylfolate is already in that active form — no conversion needed. For people with a common MTHFR gene variation, that conversion is impaired, which is why an active 5-MTHF supplement is often a better fit.

Methylation Made Simple

What is methylation? At its core, it’s a biochemical process where a tiny molecule—one carbon and three hydrogens, called a methyl group—gets handed off from one substance to another. Think of it as flipping switches ‘on’ or ‘off’ in your body. When it’s working well, it keeps your systems humming—your heart, your brain, your liver, even your energy levels. It’s behind things like making DNA, producing neurotransmitters like serotonin, and detoxifying your body.
But here’s the catch: for methylation to work, your body needs a key player called SAMe—S-adenosylmethionine. It’s like the universal handyman donating those methyl groups. And to make SAMe, your body relies on a critical B vitamin: active folate, or 5-MTHF. Add in some active B12—methylcobalamin—and you’ve got a powerhouse duo keeping this cycle running smoothly.

Now, here’s where it gets interesting. About 60% of us have a genetic quirk—something called an MTHFR mutation—that makes it harder to turn regular folic acid into the active 5-MTHF our bodies need. If that switch is off, SAMe production slows down, and suddenly, your body struggles to make things like glutathione for detox, melatonin for sleep, or even nitric oxide for healthy blood flow."
That’s why I’m excited about this little dropper from Trigquetra. It’s a liquid blend of L-methyl folate—already in that active 5-MTHF form—plus methylcobalamin, the active version of B12. No conversion needed. A dropperful on or under your tongue is like giving your body the tools it’s been asking for, especially if you’re one of those 60% with that genetic hiccup. A few drops a day, and you’re supporting your methylation cycle—your heart, your brain, your energy—all without another pill to swallow.

Favorite product hands down

I had been searching for an alternative to B12 shots and found came across this methyl b12. Within the first week of using this product, I was sold. The clean energy and mood enhancement these supplements brought to my daily routine has been life changing. I literally recommend these to everyone bc they are effective and affordable.

Life Changing

I have a double dose of MTFR gene mutations. With a COMT mutation causing my body to rapidly metabolize serotonin,norepinephrine, and dopamine (faster that I'm able to absorb it). So SSRI, and SSNRIs never helped for more than a couple months and I've spent the last 50 years wondering why i was so different and the ladt 30 years trying for a dopamine, norepinephrine, serotonin 'fix' (not good) while also profoundly depressed and anxiety making it hard to leave my home. (Dangerous combo)
After my Dr got the test results she said "start taking this asap".. I feel like I've healed 2 years in 2 months on most days. The others days i realize I still got 28 years or so to heal from and that's OK. I honestly think my PCP and your product saved my life. "Thank you" will never be enough. I just found out my 15 year old daughter has the same mutations however it was suggested to start her at 7.5 MG. Is there a simple solution to this? Half dose of the liquid maybe? Or? I just don't ever want anyone to experience what happened with me. Thank you again so much!!!
