Why I made this
“I optimized everything and still felt off. Twenty years chasing performance, triathlete, marathon runner, martial artist, and I still couldn’t feel the difference. A genetic test explained why: an MTHFR variant meant my body couldn’t use standard vitamins. So I built the one that didn’t exist on the shelf.”

The folate difference

Methylfolate vs folic acid, explained.

Methylfolate (L-5-MTHF, or L-5-methyltetrahydrofolate) is the biologically active form of folate, the version your cells use directly. Unlike folic acid, which is a synthetic compound that must be enzymatically converted through a multi-step process involving the MTHFR enzyme, L-5-MTHF crosses cell membranes and enters the methylation cycle without conversion step. A conventional multivitamin leans on synthetic precursors like folic acid and cyanocobalamin that your body has to convert first. METHL skips that step: folate as 5-MTHF (L-methylfolate), B12 as methylcobalamin, and B6 as P5P.

Why it matters for MTHFR. An estimated 40-60% of people carry MTHFR gene variants (C677T or A1298C) that reduce MTHFR enzyme activity. This slows or blocks the conversion of folic acid into usable methylfolate. The result: even with a folic-acid-rich diet or a standard supplement, methylation may still be under-supported. L-5-MTHF bypasses this bottleneck entirely, delivering active methylfolate whether or not your MTHFR gene operates at full capacitynto usable folate. For them, an ordinary multivitamin can leave nutrients on the table. Methylated forms are bioavailable whether or not you carry the variant, a smart default for everyone, not only MTHFR.

Which METHL products contain methylfolate? Both the Methylated Multivitamin and the Liquid B-Complex deliver L-5-MTHF. The capsule multivitamin provides 5-MTHF alongside 18 other active nutrients, immunity blend and fermented organic greens in one daily serving. The Liquid B-Complex delivers 500 mcg L-5-MTHF per 2 mL dose in a clean vegetable-glycerin base with methylcobalamin, P5P and TMG. Both are designed to work togetherg methylated folate means no conversion bottleneck and no unmetabolized folic acid left over. Read the full breakdown in our guide to methylfolate vs folic acid.

How much methylfolate do you need? Most adults benefit from 400-800 mcg of methylfolate daily. The Methylated Multivitamin and Liquid B-Complex each provide 5-MTHF within a broader active-B framework. If you have confirmed MTHFR variants or your provider recommends higher folate support, the Bundle gives you both products for the most complete methylation foundation METHL offersus fermented organic greens. Add the Liquid B-Complex Drops (methylcobalamin + TMG) if energy, mood and B-vitamin support are your focus. The Bundle pairs both for full-spectrum coverage at the best value. Not sure which to pick? Our buyer’s guide to the best methylated multivitamin walks through what to look for. Every formula is made in the USA, third-party tested, vegan and non-GMO, with no synthetic fillers, backed by a 60-day money-back guarantee.

If this sounds familiar

The problem isn’t you. It’s the form of your folate.

Most supplements use folic acid, a synthetic compound that requires conversion through the MTHFR enzyme before your cells can use it. If that conversion runs slowly (as it does for up to 40% of people with MTHFR variants), your folate status may be chronically under-supported even when you supplement. L-5-MTHF bypasses the problem entirely slow, you can take a vitamin every day and still run low. Here’s what that feels like, and what METHL does about it.

Low, flat energy

You sleep enough but still drag

B vitamins turn food into usable energy. When they arrive as inactive forms your cells can’t use, the tank never really fills.

METHL uses methylcobalamin B12 and active B vitamins your cells use on contact, no conversion step in between.

Brain fog

Words and focus slip mid-afternoon

Methylation helps build the neurotransmitters behind focus and mood. Weak conversion of folate and B12 can leave that process short.

METHL delivers 5-MTHF folate and methylcobalamin, the forms that feed methylation directly.

An MTHFR variant

You convert folic acid poorly

Roughly a third to half of people carry an MTHFR variant that slows the switch from folic acid to usable folate, so standard multis underdeliver.

METHL is built for MTHFR: it skips the conversion entirely with pre-activated folate. See the MTHFR guide.

Synthetic folic acid

Your label lists “folic acid”

Unconverted folic acid can build up in the blood. It’s cheap to manufacture, which is why most multivitamins still use it.

METHL uses no synthetic folic acid, only natural 5-MTHF. See the difference.

Poor absorption

You take pills that pass right through

Cheap binders, fillers and hard tablets can limit how much actually reaches your bloodstream.

METHL is a clean vegan formula with no synthetic fillers, plus a fast-absorbing liquid B-Complex option.

Trusting the label

You can’t tell what’s really inside

Supplement quality varies widely, and most brands never show third-party proof.

Every METHL batch is third-party tested for purity and potency, vegan, non-GMO, made in the USA.

Low mood & stress

You feel flat, wired, or on edge

Your body uses methylation to build serotonin, dopamine and other mood chemicals. Weak B-vitamin status can leave that supply short.

METHL delivers 5-MTHF, methylcobalamin and P5P (B6), the active forms behind neurotransmitter production.

Heart & homocysteine

You want to support healthy homocysteine

Folate, B12 and B6 work together to keep homocysteine in a healthy range. In inactive forms, they can’t do that job as well.

METHL provides all three as active, methylated forms your body can put to work directly.

Run-down immunity

You catch whatever’s going around

Daily nutrient gaps can leave your defenses under-supported, especially through busy or high-stress stretches.

The Methylated Multivitamin adds an immunity blend: vitamin C from organic cherry and amla, plus zinc and selenium.

Plant-based diet

Your diet leaves real gaps, especially B12

Vegan and vegetarian diets are often low in B12 and a few other nutrients that are hard to get from plants alone.

METHL is fully vegan and plant-derived, with B12 as methylcobalamin in a form your body absorbs.

Too many pills

Your supplement shelf is out of control

Juggling five or six bottles is easy to start and hard to keep up. Most days something gets skipped.

METHL pulls your daily foundation, greens and immunity into one clean capsule, with the Bundle if you want B-Complex too.

Sensitive stomach

Pills upset your stomach or are hard to swallow

Hard tablets, fillers and binders can sit heavily, so you stop taking them.

METHL skips synthetic fillers, and the fast-absorbing Liquid B-Complex is an easy no-pill option.

Questions, answered

The methylfolate FAQ.

What is methylfolate (L-5-MTHF)? +

Methylfolate, or L-5-MTHF (L-5-methyltetrahydrofolate), is the biologically active form of folate your cells use in the methylation cycle. Unlike folic acid, which is synthetic and must be enzymatically converted, L-5-MTHF enters cells directly and is ready to use on contact. It supports DNA synthesis, homocysteine metabolism, and neurotransmitter production. When you see "5-MTHF" or "methylfolate" on a label, that is the active form METHL uses.

What is the difference between methylfolate and folic acid? +

Folic acid is a synthetic compound not found in nature. Your body must convert it through a multi-step enzymatic pathway involving the MTHFR enzyme before cells can use it. L-5-MTHF is the active end-product of that conversion, already in the form your cells run on. Choosing methylfolate means skipping the conversion entirely. For the 40-60% of people with MTHFR gene variants, this matters because their conversion pathway runs at reduced efficiency. METHL uses 5-MTHF and never uses synthetic folic acid.

Who needs a methylfolate supplement? +

People with MTHFR gene variants (C677T or A1298C) benefit most directly because folic acid conversion is impaired. Estimates suggest 40-60% of the population carries at least one variant. Beyond MTHFR, anyone who wants folate in a form their body uses on contact can benefit, including those supporting pregnancy planning, cardiovascular health, mood, or focus. You do not need a genetic test to benefit from methylfolate.

When is the best time to take a methylfolate supplement? +

Morning with food is the most practical time for most people. B vitamins including methylfolate support energy production, so morning dosing fits naturally into daily routines. The Methylated Multivitamin is designed for once-daily use with a meal. The Liquid B-Complex can be taken at the same time or separately. Consistency matters more than the exact hour.

How much methylfolate (5-MTHF) per day? +

Most adults benefit from 400-800 mcg of methylfolate daily, covering standard dietary-reference intake for folate and supporting methylation cycle function. METHL's Liquid B-Complex delivers 500 mcg L-5-MTHF per 2 mL serving. The Methylated Multivitamin includes 5-MTHF as part of its active-B profile. Higher therapeutic doses (1-15 mg) are sometimes used under clinical supervision for confirmed MTHFR variants or elevated homocysteine.

How does the subscription work? +

Subscribe and save on every product. Your order ships on your schedule and you can pause, skip or cancel anytime.

What’s the difference between methylfolate and folic acid? +

Folic acid is a cheap synthetic form your body has to convert before it can use it. Methylfolate (5-MTHF) is the active folate your cells use directly. If you carry an MTHFR variant that conversion is limited, so methylfolate means no bottleneck and no unmetabolized folic acid left over.

Are there side effects to methylated B vitamins? +

Methylated B vitamins are well tolerated by most people. Because the active forms are potent, some people new to them notice a short adjustment period; taking them in the morning with food helps. If you have a specific health condition, check with your provider first.

How does METHL compare to other methylated multivitamins? +

METHL uses fully active forms across the board, 5-MTHF folate, methylcobalamin B12 and P5P B6, with fermented organic greens, no synthetic folic acid and no fillers, in a glass bottle, made in the USA and third-party tested. The quick test for any brand: read the label. If you see folic acid or cyanocobalamin, it isn’t fully methylated.

How do I take the Methylated Multivitamin? +

Take your daily serving once a day, ideally with a meal so the fat-soluble nutrients absorb well. Follow the serving size printed on your bottle.

How do I take the Liquid B-Complex? +

Shake well, then take 2 full droppers (2 mL) daily. You can take it straight, hold it under your tongue for a few seconds, or add it to water or juice.

Can I take the Multivitamin and Liquid B-Complex together? +

Yes. They’re designed to work together, which is exactly what the Bundle is. The multivitamin covers your daily foundation while the liquid adds concentrated, fast-absorbing active B vitamins.

What’s the difference between the capsule multivitamin and the liquid B-Complex? +

The Methylated Multivitamin is a complete daily foundation with vitamins, minerals, fermented organic greens and an immunity blend in a vegan capsule. The Liquid B-Complex is a focused dose of active B vitamins in a fast-absorbing liquid for energy, mood and methylation support.

Should I take methylated vitamins with food or on an empty stomach? +

Take the multivitamin capsule with food for the best absorption and the easiest-on-the-stomach experience. The Liquid B-Complex works with or without food.

What time of day should I take B vitamins? +

Morning is ideal. B vitamins support energy production, so most people prefer them earlier in the day rather than right before bed.

How long does one bottle of Liquid B-Complex last? +

About a month. Each 2 fl oz bottle holds roughly 30 daily servings at the 2 mL dose.

Can I take more than the recommended dose? +

Stick to the label. With B vitamins, more is not better, and there’s no benefit to doubling up. If you have questions about dosing for your situation, ask your healthcare provider.

What if I miss a day? +

Just take your next dose as usual. Methylated vitamins work best with steady daily use, so consistency matters more than any single day.

Can I take METHL every day, long term? +

Yes. METHL is built for daily use. You don’t need to cycle off it.

What form of folate does METHL use? +

5-MTHF (L-methylfolate), the active, body-ready form of folate, never synthetic folic acid. Read the full 5-MTHF guide.

What form of B12 is in METHL? +

Methylcobalamin, the active form of B12, rather than cheaper synthetic cyanocobalamin.

What form of B6 does METHL use? +

P5P (pyridoxal-5-phosphate), the active coenzyme form of vitamin B6 your body can use directly.

Does METHL contain synthetic folic acid? +

No. METHL never uses synthetic folic acid. You get natural 5-MTHF instead, which is especially important if you have an MTHFR variant. Here’s why that matters.

Does the Multivitamin contain greens? +

Yes. It includes a fermented organic greens blend alongside the methylated vitamins, minerals and an immunity blend with vitamin C from organic cherry and amla berry, plus zinc and selenium.

Who should take a methylated multivitamin? +

Anyone who wants reliably absorbable nutrients. Active forms benefit everyone, and they’re particularly useful if you have an MTHFR variant, eat a limited diet, or feel low on energy despite taking a standard multi.

Can both men and women take METHL? +

Yes. METHL is formulated for adults of any gender who want active, methylated nutrition.

Is METHL vegan? +

Yes. Both the Methylated Multivitamin and the Liquid B-Complex are vegan and plant-derived, including the capsule.

Is METHL gluten-free? +

Yes. METHL is gluten-free and non-GMO, with no synthetic fillers.

Is the Liquid B-Complex soy-free? +

Yes. The Liquid B-Complex is soy-free, sugar-free, alcohol-free and oil-free, with no synthetic preservatives.

Does METHL contain dairy or animal products? +

No. METHL is fully plant-derived and vegan, so there are no dairy or animal ingredients.

Is there sugar in the Liquid B-Complex? +

No added sugar. It’s naturally sweet on its own, with no sugar, alcohol or synthetic sweeteners.

Why is the liquid naturally sweet if it has no sugar? +

The pleasant taste comes from the plant-derived, self-preserving formula itself, not from added sugar or artificial sweeteners.

Where is METHL made? +

METHL is made in the USA and every batch is third-party tested for purity and potency.

How should I store my methylated vitamins? +

Keep them in a cool, dry place away from direct light and heat. Always reseal the cap, and follow any storage note on your label.

Do I need to shake the Liquid B-Complex? +

Yes. Shake well before each use so the active nutrients are evenly distributed in every dropper.

Will methylated B vitamins turn my urine bright yellow? +

It can, and that’s harmless. The bright color comes from riboflavin (B2) and simply means your body is passing what it doesn’t need that day.

Can I take METHL with my medications or other supplements? +

Usually yes, but always check with your healthcare provider first if you take prescription medication or other supplements, so they can confirm it fits your routine.

Can I take METHL if I’m pregnant or breastfeeding? +

Talk to your OB or healthcare provider before starting any supplement during pregnancy or breastfeeding. Many clinicians favor the active 5-MTHF form of folate, but your provider should guide what’s right for you.

How is METHL different from the multivitamin I have now? +

Most multivitamins rely on synthetic precursors like folic acid and cyanocobalamin that your body must convert. METHL delivers the active forms directly, in a clean vegan formula with greens and an immunity blend, third-party tested and made in the USA.
