Metabolism & Energy Support
B vitamins are cofactors in every energy-production pathway. METHL delivers them in the forms your cells actually use—methylcobalamin B12, active 5-MTHF folate, P5P B6—so your metabolism has what it needs to turn food into fuel.

B vitamins and energy metabolism, explained.
B vitamins and energy metabolism. Every cell in your body produces energy through a series of enzymatic reactions—the citric acid cycle and oxidative phosphorylation—that require B vitamins as coenzymes. B12 (methylcobalamin), folate (5-MTHF), and B6 (P5P) are all active participants in these pathways, not bystanders. Without adequate B vitamins, the pathways that convert carbohydrates, fats, and protein into ATP run at reduced capacity.
Active vs synthetic forms. Standard supplements use synthetic precursors like cyanocobalamin (B12) and folic acid (folate) that your body must convert to active coenzyme forms before your metabolism can use them. METHL delivers methylcobalamin, 5-MTHF, and P5P—the active coenzyme forms—directly. No conversion step, no bottleneck.
The MTHFR connection. An estimated 40–60% of people carry an MTHFR gene variant that limits conversion of synthetic folic acid to usable folate. That same pathway affects how efficiently your body runs methylation reactions linked to energy production. Active forms bypass this entirely, a smart default for everyone.
Which METHL supports metabolism best? The Liquid B-Complex Drops deliver concentrated methylcobalamin B12, 5-MTHF and P5P in a fast-absorbing liquid base—the highest B-vitamin density in the line. Pair it with the Methylated Multivitamin for full-spectrum daily coverage, or grab the Bundle for both at the best value. Also looking for energy support? See our vitamins for energy collection. Every formula is made in the USA, third-party tested, vegan and non-GMO, backed by a 60-day guarantee.
The problem isn’t you. It’s the form of your vitamins.
Most multivitamins are built on synthetic precursors your body has to convert before it can use them. If that conversion runs slow, you can take a vitamin every day and still run low. Here’s what that feels like, and what METHL does about it.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

People who finally feel it.
“Absolutely the best vitamins I have ever taken. These vitamins are absolutely the best.”
“My doctor gave me a list of recommended vitamins for my neuropathy. Your product was recommended because it provides more of the vitamins than other products. Makes my daily routine easier.”
“Well tolerated!”
“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.”

Why you can trust METHL
The metabolism & B-vitamin FAQ.
What is a methylated multivitamin? +
It delivers folate and B12 in their active forms (5-MTHF and methylcobalamin), so your body doesn’t have to convert them first. Read our full guide to what a methylated multivitamin is.
What vitamin helps with tiredness and fatigue? +
The B vitamins, especially B12, B6, folate and B3, are central to turning food into energy. Iron, magnesium and vitamin C also contribute. Low B12 often shows up as fatigue or brain fog.
Is B6 or B12 better for energy? +
They work together rather than competing. B12 is often the one linked to fatigue when low, while B6 supports the same energy pathways, which is why a full B-complex beats a single vitamin.
Is there a pill that will give you energy? +
Vitamins aren’t stimulants, they help your cells produce energy from food rather than borrowing it. Filling a genuine nutrient gap can help you feel less depleted over time.
What supports a healthy metabolism? +
Sleep, movement, protein and steady blood sugar matter most. On the nutrition side, the B vitamins support the pathways that convert food into energy, especially in their active, ready-to-use forms.
Is it third-party tested? +
Yes. Every batch is third-party tested for purity and potency, so what’s on the label is what’s in the bottle. We believe verification should be the standard, not a marketing line.
Can I take it every day? +
Yes, it’s built as a daily foundation. The water-soluble vitamins aren’t stored, so any excess is simply excreted. Start at the labeled dose and take it with food for the best absorption.
Can I take it if I’m pregnant or breastfeeding? +
Nutrient needs change during pregnancy and breastfeeding, so this isn’t a substitute for a prenatal your provider recommends. Talk with your clinician about the right formula and dose for you before starting.
Can I take it with my medications or other supplements? +
Most people can, but some nutrients can interact with certain medications. If you take prescription medication or have a health condition, check with your clinician or pharmacist first.
