Support nerve function and methylation with the most active form of B12

Each capsule provides 1000mcg of vitamin B12 as methylcobalamin, the cytoplasmic active form of B12 that serves as a cofactor for the enzyme methionine synthase. This enzyme converts homocysteine to methionine, a reaction that is central to the methylation cycle. Methylation is one of the body's most important biochemical processes, governing gene expression, neurotransmitter production (serotonin, dopamine, noradrenaline), detoxification, myelin sheath maintenance and histamine clearance.

Methylcobalamin is the most commonly recommended active B12 form because methylation dysfunction is widespread (driven by MTHFR gene variants, nutritional deficiencies and high toxic burden). At 1000mcg per capsule, this provides a therapeutic dose appropriate for addressing B12 deficiency, supporting methylation, managing elevated homocysteine and neurological support. The capsule format provides a higher dose than the liquid versions, making it the preferred choice when a substantial daily B12 dose is required. The vegetarian capsule shell makes this suitable for most dietary requirements.

Key benefits:

  • Nerve repair and brain function
  • Direct methylation no conversion
  • Most active form of B12
Each capsule contains: %NRV*
Vitamin B12 1000 mcg 40000%

† Nutrient Reference Value (NRV*) not established

Cellulose, Hydroxypropyl Methylcellulose (capsule), Methylcobalamin.

Directions for use:

Take 1 capsule per day with food.

Taking with a meal supports absorption. For those new to methylcobalamin who have known methylation sensitivities (COMT variants, histamine intolerance), start with the liquid form (86.5mcg per drop) as the lower dose allows gentler introduction. Some individuals experience overstimulation, anxiety or insomnia when starting methylcobalamin at high doses, which typically resolves by starting low and increasing gradually.

For comprehensive B12 coverage, pair with Vitamin B12 Adenosylcobalamin Capsules to support both cytoplasmic methylation and mitochondrial energy production simultaneously.
