NOW Foods Methyl B-12 5000 mcg Lozenges (Item #0496 / N0496)
High-potency, sublingual Vitamin B-12 (as Methylcobalamin) paired with Quatrefolic® methylfolate for direct cellular absorption, nervous system resilience, and sustained metabolic energy.
If you struggle with fatigue, sluggish focus, or age-related absorption hurdles, standard swallowable vitamin tablets often fall short. NOW® Foods Methyl B-12 delivers 5,000 mcg of pre-converted, biologically active methylcobalamin in a fast-dissolving lozenge. It bypasses complicated digestive bottlenecks, delivering pure coenzyme nutrition straight to your bloodstream.
✓ 5,000 mcg Bioactive B-12Ready for immediate cellular use without liver conversion steps.
✓ Quatrefolic® Folate SynergyIncludes 680 mcg DFE active (6S)-5-MTHF for balanced homocysteine recycling.
✓ Sublingual Oral DeliveryDissolves under the tongue to circumvent low stomach acid and digestive barriers.
✓ 100% Vegan & Allergen-CleanGluten-free, soy-free, non-GMO, and crafted in an A-rated GMP facility.
Not all Vitamin B-12 supplements work the same way in the human body. Most generic multivitamins and cheap drugstore tablets use cyanocobalamin—a synthetic form bound to a cyanide molecule. To use cyanocobalamin, your body must expend cellular energy in the liver to strip away the cyanide and convert the molecule into active methylcobalamin.

Primary Health Benefits: Energy, Nerves, and Cardiovascular Balance
Vitamin B-12 acts as an essential coenzyme across fundamental metabolic pathways. When taken at the therapeutic potency of 5,000 mcg, its physiological benefits become pronounced:
1. Cellular Energy Without the Jitters
Unlike caffeine or nervous-system stimulants, B-12 does not manufacture artificial energy. Instead, it serves as an indispensable cofactor in the Krebs cycle, converting dietary carbohydrates, proteins, and fats into usable cellular ATP (adenosine triphosphate). It fights genuine cellular fatigue at the root source.
2. Myelin Sheath & Nerve Preservation
Methyl B-12 is crucial for synthesizing the myelin sheath—the protective insulation surrounding your nerve fibers. Maintaining adequate B-12 levels safeguards delicate peripheral nerves in your hands and feet against numbness, tingling, and chronic neurological discomfort.
3. Healthy Homocysteine & Brain Function
Elevated homocysteine is a recognized biomarker for cardiovascular and cognitive decline. Methylcobalamin, working in tandem with the included Quatrefolic® folate, donates a methyl group to recycle homocysteine into harmless methionine, protecting blood vessel walls and supporting memory.
Dietary supplement safety depends on analytical verification. NOW Foods maintains one of the most comprehensive private analytical testing footprints in North America, ensuring that every batch of Item #0496 meets uncompromising purity and identity benchmarks.

HPLC & UPLC Potency Verification
High-Performance Liquid Chromatography (HPLC) verifies that every lozenge delivers 100% of its claimed 5,000 mcg methylcobalamin and 680 mcg DFE folate through its expiration date.
Microbiological & Allergen Screening
Every production run is screened for pathogenic contaminants (Salmonella, E. coli, yeasts, and molds) and produced in cGMP facilities strictly audited to prevent cross-contact with allergens.
Strict Adherence Standard: NOW adheres strictly to FDA 21 CFR Part 111 cGMP regulations, United States Pharmacopeia (USP) monographs, and rigorous voluntary safety screens, rejecting any raw material that fails to meet baseline purity limits.

How to Take Sublingual B-12 for Optimal Absorption
To receive the full benefits of this 5,000 mcg dosage, delivery technique matters. Unlike common pills that you swallow whole with water, this lozenge is engineered for sublingual mucosal diffusion.
Step 1: Placement Under the Tongue
Place 1 lozenge under your tongue or between your gum and cheek. Allow it to dissolve slowly rather than immediately swallowing it.
Step 2: Passive Oral Diffusion
As it dissolves over 3 to 5 minutes, active methylcobalamin passes directly through the mucous membrane into the sublingual capillary bed, entering circulation immediately.
Step 3: Ideal Morning Timing
Take your dose in the morning with or after breakfast. Because B-12 supports cellular energy pathways, taking it late in the evening may interfere with sleep in sensitive individuals.
Safety, Edge Cases & Important Medical Considerations
At VitaNet, responsible supplementation means providing clear, transparent medical guidance. While Vitamin B-12 is recognized as exceptionally safe, keep these specific clinical considerations in mind:
⚠ Household Pet Warning (Xylitol Content)
This product contains Xylitol as a natural sweetener. While completely safe for human consumption, Xylitol is extremely toxic to dogs and cats, even in tiny amounts. Store this bottle securely out of reach of household pets, and contact a veterinarian immediately if accidental pet ingestion occurs.
Water-Solubility & High-Dose Tolerability
Vitamin B-12 is water-soluble. The Institute of Medicine (National Academies of Sciences) has not established a Tolerable Upper Intake Level (UL) for B-12 because excess amounts are readily excreted through the kidneys. A temporary slight pink tint in your urine is completely normal and harmless.
Medication Interactions & Absorption Blockers
Common prescription medications—such as Metformin (for blood sugar) and proton pump inhibitors (PPIs like omeprazole or pantoprazole)—impair gastrointestinal B-12 absorption. A sublingual lozenge is advantageous here because it bypasses the digestive tract. Always inform your physician when supplementing.
Special Contraindication: Leber's Hereditary Optic Neuropathy
Individuals diagnosed with Leber's hereditary optic atrophy should avoid high-dose cobalamin supplementation without direct neuro-ophthalmologist oversight, as optic nerve complications have been reported.

Frequently Asked Questions (FAQ)
What makes Methyl B-12 5,000 mcg different from standard Cyanocobalamin B-12?
Cyanocobalamin is a synthetic molecule bound to cyanide that requires multi-step liver de-cyanation before your body can use it. Methylcobalamin is already in its bioactive, coenzyme form, meaning your cells, brain, and nerves can utilize it immediately without any metabolic conversion hurdles.
Why is this Vitamin B-12 formulated as a lozenge instead of a swallowable pill?
Swallowed tablets depend on stomach acid and an intestinal protein called "intrinsic factor" to be absorbed. Many adults—especially seniors and individuals taking acid blockers—lack adequate intrinsic factor. Dissolving this lozenge sublingually under your tongue allows Vitamin B-12 to enter the bloodstream directly through the oral mucosa, bypassing digestive roadblocks.
Is 5,000 mcg of Vitamin B-12 safe, or is it too high of a dose?
Yes, 5,000 mcg is safe and clinically standard for addressing deficiencies. Vitamin B-12 is water-soluble with no known toxicity threshold; your body uses what it needs and safely flushes excess amounts through urine. Even with high doses, the body absorbs only a calculated percentage via passive diffusion, making 5,000 mcg an ideal therapeutic strength.
Why does NOW Foods include Quatrefolic® methylfolate in this formula?
Folate and Vitamin B-12 work together as biochemical partners in the one-carbon cycle to synthesize DNA and convert homocysteine to methionine. By including patented Quatrefolic® (active 5-MTHF) instead of synthetic folic acid, this formula ensures that individuals with MTHFR gene variants get complete, synergistic cellular support.
How does NOW Foods verify the purity and heavy metal safety of this supplement?
NOW Foods tests raw ingredients and finished goods in its private ISO/IEC 17025:2017 accredited analytical laboratories. Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), they test down to parts-per-billion limits for lead, arsenic, cadmium, and mercury, adhering to California Proposition 65 thresholds and FDA cGMP standards. Potency is verified using High-Performance Liquid Chromatography (HPLC).
When is the best time of day to take this B-12 lozenge?
It is best taken in the morning or early afternoon with a meal. Because Vitamin B-12 activates metabolic energy production, taking it late in the evening may disrupt restful sleep patterns in sensitive individuals.
Why should I purchase NOW Methyl B-12 from VitaNet?
VitaNet has been a family-owned, independent health food retailer since 1995 with over 31 years of trusted experience[cite: 1]. We offer authentic manufacturer products, BBB A+ accreditation[cite: 1], and a risk-free 100% money-back guarantee where we even pay return shipping on opened bottles[cite: 1].
