Find the right L-Methylfolate formula
Over half of people can't efficiently convert folic acid into active folate. L-Methylfolate (5-MTHF) arrives already active — a bioavailable form that enters the cell without that step.

How to choose
The dose depends on where you're starting from.
1 mg is the starting point for most people. 2.5 mg is the balanced everyday dose. 5 and 10 mg are for targeted support, usually after a homocysteine test or on a practitioner's advice.
The form is the same at every dose: active 5-MTHF.
- Clinical doses
- Four strengths
Why the active form
Why active folate, not folic acid?
Folic acid is inactive. Your body activates it with the MTHFR enzyme — and in over 50% of people it runs slow, so part of the dose is lost.
L-Methylfolate is the final, active form. There's nothing to convert — it reaches the cells from the first capsule.
- No folic acid
- MTHFR-variant friendly

A cleaner formula, a better form, a real result.

What the leading experts say
Why healthy methylation is in the protocols of the world's best:
Up to 60% of the population has an MTHFR gene mutation. That means you CANNOT process folic acid effectively. You need methylfolate.
Folic acid is basically a square wheel to your body. It has to be processed by many different enzymes so your body can turn it into a round wheel — L-methylfolate.
Methylfolate and methyl B12 work together to control methylation reactions that regenerate your DNA and brain cells.
People with MTHFR mutations have a significantly higher risk of depression, anxiety and cognitive decline — all of which can improve with the right methylated supplementation.
Methylfolate is the main circulating form of folate, used to produce serotonin, dopamine and norepinephrine.
Optimizing methylation with the right forms of B vitamins is one of the most powerful interventions in functional medicine.
Homocysteine is one of the best markers of methylation status. If it's above 10 µmol/L, you have a problem worth addressing.
Methylation is one of the key markers I track in Blueprint. It's measurable, it's optimizable, and it's critical for longevity.
For my patients with autoimmune conditions and multiple sclerosis, optimizing methylation with methylated B vitamins is a critical part of the protocol.
These days I don't take many supplements. But B12 and methylfolate are non-negotiable for me, for their key role in homocysteine control and longevity.

Frequently asked questions
What is L-methylfolate, and how is it different from folic acid?
L-methylfolate (5-MTHF) is the active form of folate — folate in the exact form your body can use immediately. Folic acid is a synthetic form that has to be converted through multiple steps in your body, and around 50% of people worldwide struggle with that conversion (a gene variation). L-methylfolate skips the bottleneck.
The result? Better absorption and effectiveness, especially for the brain and mood benefits. It's like giving your body folate fuel that's already ready to burn — which makes the results more reliable. Every Cellova Health product that provides folate uses L-methylfolate of the highest concentration and purity, so you get the full benefit of this vital nutrient.
What is "methylation", and why does it matter for your health?
Methylation is a fundamental biochemical process in your body: a "methyl" group (one carbon plus three hydrogens) gets attached to other molecules.
It happens in every cell, every second, and it's essential to many vital functions: from regulating neurotransmitters (which shape mood and brain function) to cellular energy, detoxification, immune function, and even switching genes on and off.
Methylation is your body's maintenance and regulation system. When it runs well, you get better energy, better mood and better overall health. Nutrients like folate, B12 and B6 are its key drivers.
That's exactly why Cellova Health focuses on them. By supporting methylation, we address a root cause that can drive broad improvements in health. In short: healthy methylation = a healthier life.
Who can benefit from L-methylfolate supplements?
They're built for anyone who wants to optimize mood, brain function and long-term wellbeing. You don't need a diagnosed condition or a genetic mutation to benefit.
Folate supports the everyday body and brain functions all of us run on. People with certain health and mental-health concerns tend to notice the most.
If you carry an MTHFR gene variant, or process folate poorly, our L-methylfolate and B-Complex can be especially useful.
And even if you're broadly healthy but want to keep your edge and protect your health long-term, extra support for methylation, detox, cognition and cellular energy is exactly what these formulas are for.
How do I pick the right dose (1 mg, 2.5 mg, 5 mg, 10 mg)?
The right L-methylfolate dose depends on your situation.
The range exists so the dose can match your specific needs:
1 mg is a great option for gentle support. It covers the basics and gives mood and metabolic health a light assist.
2.5 mg is a moderate dose — useful if you have a mild folate shortfall or want extra mood and cognitive support beyond your diet.
5 mg is a mid-to-high dose, often chosen by people with known folate-absorption issues, low mood, fatigue, higher stress loads, or on a practitioner's advice.
10 mg is our maximum strength for advanced needs — typically used when recommended by a health professional (for example as part of a therapeutic plan for mood or metabolic support).
Most people start with 1 mg or 2.5 mg and adjust as needed. People with MTHFR variants or higher folate needs usually go for 5 mg (our best seller) or 10 mg.

How does L-methylfolate combine with other supplements?
Cellova's formulas are built to work together: Advanced B-Complex delivers the cofactors (B2, B6, B12) that keep the methylation cycle running, and TMG provides a parallel source of methyl groups. The kit brings them into one protocol.
If you take a multivitamin, check the label — avoid doubling up on high doses of synthetic folic acid. Morning, with a glass of water, is the easiest way to take them together.
Is L-methylfolate safe during pregnancy?
L-methylfolate is safe — and in fact recommended — during pregnancy for prenatal support. Folate is essential for fetal development, especially the formation of the neural tube in early pregnancy.
The typical doses are 1 mg or 2.5 mg.
That said, always talk to your doctor before starting any supplement while pregnant or breastfeeding. They can set the right dose for your needs.
How long until I see results?
Everyone's body is different, but many of our customers say they feel improvements within a few weeks.
Mood and mental clarity can start improving after 2–3 weeks of daily L-methylfolate (brain fog often lifts even faster).
Energy levels and stress resilience typically improve over the first month, as your methylation processes optimize.
Subtler changes — homocysteine balance, cardiovascular markers, long-term wellbeing measures — can take 2–3 months of consistent use to show measurable differences.
The key is consistency: taking it daily lets the effect build and do its job properly. It's a bit like filling a tank — you may not feel each drop, but you'll definitely know when it's full. We recommend tracking how you feel for at least 8 weeks. And remember, we're here to support you — if anything feels off, write to us: a dose adjustment or adding a cofactor like B-Complex usually makes the difference.
Where do you source your ingredients?
We only choose ingredients that clear four requirements — ultra-pure, high-quality, easily absorbed, and of proven origin.
We buy raw materials exclusively from established industry leaders in the US, Germany, France, Japan and Italy, and test every one of them in an independent, accredited laboratory. Suppliers have to meet strict testing and quality criteria to qualify to work with Cellova Health.
Are there side effects? Is it safe long-term?
Every ingredient we use is generally recognized as safe and absorbed naturally by your body.
L-methylfolate doesn't cause side effects. In very rare cases, very high doses can bring mild headache or irritability — usually resolved by taking B12 and B6 alongside (one more reason our range includes a B-Complex).
None of our products are habit-forming, and none require cycling. All are designed for daily use and long-term health support.
As with any supplement, stick to the recommended use — taking more than the recommended dose usually adds no benefit and can raise the chance of side effects.
When is the best time to take L-methylfolate?
Morning is the best time for L-methylfolate and a methyl B-complex, since they support energy production and brain function — that way you get the benefit across the whole day. Many people also take choline in the morning for extra brain support.
