Methylation Complete 120 Tablets by Neurobiologix is a professional-grade sublingual methylation formula delivering two bioactive forms of B12, active B6, and dual-source 5-MTHF directly through the oral mucosa to support the methylation cycle, neurological function, and healthy homocysteine metabolism.
Key Benefits of Methylcobalamin, Hydroxycobalamin, 5-MTHF, and Pyridoxal-5-Phosphate Ingredients
-
Methylcobalamin (Vitamin B12, 5,000mcg)
- Supports methionine synthase enzyme activity and promotes healthy remethylation of homocysteine to methionine, a central step in the methylation cycle
-
Hydroxycobalamin (Vitamin B12, 2,000mcg)
- Promotes nitric oxide scavenging and supports healthy B12 tissue storage, providing a complementary and sustained B12 source alongside methylcobalamin
-
Dual B12 Form Delivery
- Supports a more complete B12 profile by addressing both immediate methylation cycle needs and longer-term B12 reserve maintenance through two distinct cobalamin forms
-
5-MTHF (from L-Methyltetrahydrofolate Calcium Salt and Quatrefolic, 5,440mcg DFE)
- Supports active folate delivery to the methylation cycle and promotes neurological and immune function without requiring MTHFR enzyme conversion
-
Quatrefolic (6S-5-Methyltetrahydrofolic Acid, Glucosamine Salt)
- Promotes enhanced stability and solubility of active folate and supports superior bioavailability compared to calcium salt forms alone
-
Pyridoxal-5-Phosphate (Vitamin B6, 2mg)
- Supports transsulfuration pathway activity and promotes healthy conversion of homocysteine to cysteine, supporting glutathione biosynthesis downstream
-
Sublingual Fast-Dissolve Delivery
- Promotes direct absorption through the oral mucosa, bypassing gastrointestinal conversion requirements and supporting maximum delivery of active B vitamins to the nervous and immune systems
-
Glutathione Production Support
- The methylation cycle supported by this formula promotes healthy glutathione synthesis, supporting the body's primary intracellular antioxidant defense
-
MTHFR and MTRR Variant Support
- Provides folate and B12 in pre-converted, biologically active forms, supporting individuals with MTHFR or MTRR gene variants who have reduced enzymatic conversion capacity
-
Neurotransmitter Synthesis Support
- Active folate and B12 support the enzymatic reactions involved in serotonin, dopamine, and norepinephrine synthesis, promoting healthy mood and cognitive function
-
Homocysteine Metabolism Support
- The combination of methylcobalamin, 5-MTHF, and P5P supports healthy remethylation and transsulfuration of homocysteine, promoting cardiovascular function and neurological health
Methylation Complete is formulated around sublingual delivery, a clinically meaningful distinction from standard oral capsule or tablet supplements. By dissolving under the tongue, the active B12 and folate forms are absorbed directly into the bloodstream through the oral mucosa, bypassing the gastrointestinal tract and the hepatic first-pass effect that can reduce the bioavailability of standard oral supplements. The combination of methylcobalamin and hydroxycobalamin addresses both the immediate methylation cycle requirement for methyl-donor B12 and the longer-term need for a stable B12 reservoir, while the dual-source 5-MTHF using both calcium salt and Quatrefolic provides active folate with enhanced stability and solubility across a broader physiological range.

Frequently Asked Questions
Who is Methylation Complete designed for?
Methylation Complete is formulated for adults seeking comprehensive methylation cycle support, particularly those with MTHFR or MTRR gene variants, elevated homocysteine levels, neurological support needs, or conditions associated with impaired B12 or folate metabolism. It is commonly used as the activating B12 cofactor in protocols that also include Methyl Folate Plus or other folate-focused supplements.
How should Methylation Complete be taken?
The recommended use is 1 tablet placed under the tongue or in the mouth twice daily, allowing 1 to 3 minutes for the tablet to dissolve. The standard schedule is 1 tablet in the morning and 1 tablet in the evening, 2 to 3 hours before bedtime. For individuals with higher support needs, a healthcare practitioner may recommend 1 tablet three times daily. Children under 5 years of age and individuals who are pregnant or breastfeeding should consult a healthcare provider before use.
Methylcobalamin and hydroxycobalamin serve complementary roles in B12 metabolism. Methylcobalamin is the active methyl-donor form that directly supports the methionine synthase enzyme in the methylation cycle. Hydroxycobalamin is a precursor form that the body can convert to both methylcobalamin and adenosylcobalamin as needed, supporting broader B12 tissue storage and utilization. Together they provide more complete B12 support than either form alone.
Quatrefolic is a patented form of 5-MTHF in which the active folate molecule is stabilized with a glucosamine salt rather than a calcium salt. This formulation promotes enhanced water solubility and stability across a wider pH range, supporting more consistent bioavailability.
