Longevity Supplements
Methylation governs DNA repair, epigenetic maintenance and homocysteine balance. B12 and folate status decline with age, and MTHFR variants limit activation. METHL delivers active forms your body uses directly to support already-healthy homocysteine levels and healthy aging.

3 productsMETHL delivers longevity supplements built on the mechanism that matters most: methylation. Active B12 as methylcobalamin and folate as 5-MTHF help maintain already-healthy homocysteine levels, support DNA methylation and epigenetic maintenance, and give your body the active forms it can use regardless of MTHFR status.

Longevity supplements and the methylation connection.
Methylation and healthy aging. Methylation is a biochemical process in which a methyl group is transferred to DNA, proteins and other molecules, helping regulate gene expression, repair DNA and maintain cellular function. B vitamins, especially folate and B12, are essential cofactors. Research consistently links adequate B12 and folate status to maintained already-healthy homocysteine levels, and homocysteine is a well-studied marker associated with cardiovascular and cognitive wellness as we age.
Why activation matters. As we age, B12 absorption declines and the MTHFR enzyme operates more slowly in the 40-60% of people who carry a variant. That means synthetic folic acid and cyanocobalamin, the forms most supplements still use, can leave the methylation cycle short. METHL delivers folate as 5-MTHF (L-methylfolate) and B12 as methylcobalamin, active forms that require no conversion and work regardless of MTHFR status.
Methylfolate vs folic acid. Folic acid is a cheap, synthetic compound your body must convert; 5-MTHF is the active folate your cells use directly. For anyone supporting homocysteine balance, methylated folate is the more reliable choice. Read the full comparison in our guide to methylfolate vs folic acid.
The best longevity supplements to start with. Start with the Methylated Multivitamin for a complete daily foundation, 19 active vitamins and minerals plus fermented organic greens. Add the Liquid B-Complex Drops (methylcobalamin + TMG) for concentrated, fast-absorbing B-vitamin support. The Bundle combines both for full-spectrum methylation coverage at the best value. Not sure which fits your goals? Our 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.
Healthy aging starts with the right form of B vitamins.
Methylation governs how your cells maintain DNA, regulate epigenetics and keep homocysteine in a healthy range. Most longevity supplements skip the mechanism entirely by using synthetic precursors. Here is what that gap looks like, and how METHL addresses 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.

“Methylation is central to how cells maintain themselves as we age. Delivering B12 and folate in active, bioavailable forms, methylcobalamin and 5-MTHF, supports healthy homocysteine metabolism and DNA methylation, which is exactly where longevity-focused nutrition should start.”
People who feel the difference.
“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 longevity supplements 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 supplements support healthy aging? +
The best-studied foundations are the active B vitamins, vitamin D, and antioxidants, alongside real food, sleep and movement. Supplements support a healthy lifestyle rather than replace it, and don’t treat or prevent disease.
Why do methylated vitamins matter for healthy aging? +
Methylation, the process active B vitamins support, is involved in energy, DNA maintenance and homocysteine balance, and it can become less efficient with age. Active forms help keep those inputs steady.
Does B12 absorption decline with age? +
It often does, as stomach acid that releases B12 from food declines with age. The active form (methylcobalamin) is ready to use, which can be a practical choice for older adults.
How does the subscription work? +
Choose a delivery cadence at checkout and your bottles arrive on schedule, and you can pause, skip or cancel anytime from your account. It’s built so you never run out mid-routine.
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.
