Frequently asked questions

L-Methylfolate is the active form of folate that your body can use immediately. Folic acid needs to be converted—and some people can’t do that well because of genetic mutations like MTHFR.

Methyl B12 (aka Methylcobalamin) is a highly bioavailable form of B12 that works synergistically with L-Methylfolate to support brain health, energy, and mood.

Check with your doctor first.

It is possible L-Methylfolate may interact with certain medications. It is always best to check with a healthcare provider before starting any supplements.

Most people tolerate it well. If you feel like you are sensitive to higher doses, you can work your way up to the full dose over time.

It can be taken with or without food, but some people prefer it with a meal to avoid mild stomach discomfort.

My experience with this products

bought this product hoping
it would actually help me,
but unfortunately, it was
a complete disappointment.
It did absolutely nothing for me,
and I felt it was
a total waste of money.
I have to admit,
their commercial was very effective.
It definitely convinced me to buy it.
Unfortunately, the product itself
was nowhere near as effective
as the advertising made it seem.
I guess sometimes
all it takes is the right commercial
to convince people to buy
a product that simply
isn’t worth the money.

Definitely worth a try!

I had been dealing with the 2-3 PM “crashes” no matter how much caffeine I had. I’ve had a history of low B12 so I thought I would give this a try. I’m glad I did because I could already feel a difference after just a few days.

Great!

I felt better physically and mentally but I ran out. It completely eliminated my brain fog and so much more energy. I didn’t realize how long the average bottle last.

I swear by this!!

I’ve been using Triquetra Health’s L-Methylfolate 5-MTHF + Methyl B12 every single day for over a year now, and I truly won’t go without it. As someone in long-term recovery, supporting my mental clarity, mood, and energy naturally is a top priority—and this supplement has been a crucial part of that.

It’s rare to find something that’s not only clean and bioavailable, but that actually makes a real difference. I noticed improvements in focus, mood stability, and overall well-being early on, and it’s been consistent ever since. The combination of active folate and methyl B12 is perfect for those of us who can’t process synthetic forms.

If you’re in recovery or just want something that genuinely supports your brain and body, this is one supplement I wholeheartedly recommend. It’s earned a permanent spot in my routine.

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.

Disappointed

To start off I did reach out and have received no communication back. That said it took forever for the product to ship. Once received we were excited to try this product. However, to our dismay the product had been opened both outside shrink wrap safety missing and inner seal gone. I emailed customer support a week ago no response. So as it was unsafe to use product I can not speak to it. However customer service and handling times are abysmal.

Anxiety

This vitamin combo gave me high anxiety. I stopped using it and my anxiety dropped. I am c677t homo mthfr.

I was hoping it would work for me.

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!!!

Buy somewhere else

First of all, my glass syringe came broken inside the bottle. I’m glad I noticed and didn’t ingest any glass. Secondly, there was no noticed benefits while taking the unbroken bottle, but this is the only B12 supplement that made both me and my husband break out with pimples on our faces. I don’t get pimples normally and this was the only change to my diet/routine. There are so many B12 supplements out there, this one isn’t worth it. I usually take natures bounty and have felt better and had no side effects. I wanted to try this to see if there was any difference. There was only negative differences and I would never buy this brand again.

Taste great

This has a really good flavor to it, it almost tastes like candy. There's no funny texture or aftertaste to it and overall I had no sensitivities to any of the ingredients and it seems to be working well I definitely recommend it.

Helps with MTHFR mutation

Tastes like cough syrup, but it's an effective and fairly economical supplement to treat an MTHFR mutation. I like that it has the methylated B12 as well as methylfolate, as both are necessary. The methylfolate I received in July 2022 expires in May 2024.

MEGA B12

I have MTHFR so finding quality methylated b12 and methylfolate is important for maintaining my health. I prefer USDA organic and non GMO supplements. This offers both methylfolate and methylated b12. The liquid is light, fruity, and easy on the palette. It has a mega dose of b12 so I don't take this daily as it can cause anxiety for me. What I like: easy to take, portable, organic, good flavor. A+

Has a decent flavor, slightly bitter aftertaste but it's not horrible. Easy to use dropper and instructions are clear. Clean ingredient list with no color additives listed.

Strong cherry flavor. Love how it makes me feel!

I have the MTHFR mutation and it’s important to me that I take the right kind of folate/B12 so that my body is able to absorb it. This is perfect! The taste isn’t the best, but it’s not the worst. Kind of weird strong Cherry flavor. Several drops under the tongue does it! Highly recommend!

Great Product

I purchased this product due to the fact that I carry two gene mutations called MTHFR. My doctor recommended that I start taking methylated B vitamins daily. I had been taking a much cheaper brand new when I came across this product. I tried this one due to the great reviews and it hasn’t disappointed whatsoever. My mood and my energy have increased significantly and I’m doing better than I had been in many years. I will definitely keep purchasing this product.
