L-Methylfolate 7.5mg with Methyl B12 – Active 5-MTHF for MTHFR Support

What Is L-Methylfolate and Why Is It Important?

If you've ever looked at a folic acid supplement and wondered if your body can actually use it, you're not alone. Many people have a common genetic quirk in the MTHFR gene that makes converting folic acid into its active form—5-MTHF—a bit of a challenge. That's where L-methylfolate comes in. It's the biologically active form of vitamin B9, ready for your body to use straight away. Paired with methylcobalamin (the active B12), this duo supports methylation—a key process that affects everything from mood to energy to heart health.* Each capsule delivers 7.5 mg of L-methylfolate (as calcium salt) along with methyl B12, providing a potent, bloodstream-ready combination for whole body wellbeing.

Folic Acid vs. Methylfolate: What's the Difference?

Standard folic acid is a synthetic form of B9 found in fortified foods and many supplements. It needs a few enzymatic steps—including one catalysed by the MTHFR enzyme—to become the active 5-MTHF. For people with MTHFR variants (like C677T or A1298C), that conversion can be inefficient, leading to lower active folate levels. L-methylfolate skips this problem entirely. It's already in the form your body uses. Similarly, methyl B12 (methylcobalamin) is the active coenzyme, unlike the less bioavailable cyanocobalamin.

Health Benefits of Methylfolate and Methyl B12

This combo is a powerhouse for homocysteine metabolism. Homocysteine is an amino acid that, when elevated, is linked to cardiovascular issues. Methylfolate and methyl B12 work together to recycle homocysteine back into methionine, supporting normal heart health.* They also play a starring role in neurotransmitter production—serotonin, dopamine, norepinephrine—which can positively influence your mood, focus and sleep. Many users report clearer thinking and a calmer mindset. Plus, B12 is essential for normal red blood cell formation and neurological function, so you get energy and brain support in one capsule.*

Who Should Consider This MTHFR Supplement?

Anyone with known MTHFR gene variants will benefit from this active folate form. It's also great for people with elevated homocysteine levels, or those wanting to boost mood and cognitive function. If you're pregnant or breast-feeding, talk to your GP first—folate needs increase during pregnancy. For general health, even if you eat plenty of leafy greens, this supplement ensures you're getting the bioavailable form. Because it's already active, it's gentle on the stomach and well-absorbed, even for those with digestive issues.

Recommended Dosage: How Much Should You Take?

Take one capsule daily, providing 7.5 mg (7,500 mcg) of L-methylfolate and a cofactor amount of methyl B12. This dose aligns with clinical studies for homocysteine management and mood support. While the upper limit for folic acid is 1,000 mcg, methylfolate is considered safe at higher doses due to its active nature. Still, always follow the labelled or your health care provider's advice. Best taken with a meal to aid absorption. Consistency is key—daily use helps maintain steady methylation.

How to Choose a Quality Methylfolate Supplement

Look for supplements that clearly state 'L-methylfolate (5-MTHF) calcium salt' and have independent third-party testing. Triquetra Health's L-Methylfolate is Clean Labelled Project Certified, meaning it's been tested for over 200 contaminants. It's made in cGMP and organic-certified facilities in the USA, with third-party lab verification for potency and purity. Avoid products with unnecessary additives; clean labels mean you're getting just the active ingredients without fillers.

Potential Side Effects and Precautions

Methylfolate is generally well-tolerated. A few people might notice mild digestive upset, headache or sleep changes when starting, which usually settle down. High doses of folate can mask a B12 deficiency, so it's important to get enough B12—this product includes it. If you have bipolar disorder or take medications like antidepressants or anticonvulsants, check with your doctor first. Discontinue if you experience any adverse reactions. Always read the labelled and follow directions for use.

Frequently Asked Questions

Can L-methylfolate help with mood?

Absolutely. Methylfolate is crucial for making serotonin and dopamine. Some research shows people with low folate levels may see mood benefits from supplementation. This product can support a balanced mood as part of a healthy lifestyle.*

Is this supplement safe for vegans?

Yes, the capsules are vegan-friendly. The methyl B12 used is methylcobalamin, suitable for vegans.

How long does it take to see results?

It varies. Some notice changes in a few weeks; others need longer. Consistent daily use is recommended for best results.
