Provides Two Active Coenzyme Forms of Vitamin B12

  • May help support the normal conversion of homocysteine to methionine
  • May help support healthy methylation and metabolism
  • May help support cognitive health


Active B12 5000 by Seeking Health is a formula that provides two active coenzyme forms of vitamin B12 in a higher dose of 5,000 mcg (5 mg) per lozenge. Methylcobalamin and adenosylcobalamin, the two active coenzyme forms of vitamin B12, serve an important role in red blood cell formation, methylation reactions, brain and nervous system function, energy metabolism and immune system regulation.*

Why choose Active B12 5000 by Seeking Health?

Active B12 5000 provides two active coenzyme forms of vitamin B12, methylcobalamin and adenosylcobalamin. Vitamin B12 is provided at significantly higher potency than the recommended daily allowance (RDA) to bypass usual mechanisms of absorption that rely on intrinsic factor.* These B12 lozenges dissolve in the mouth within a few minutes or may also be swallowed whole if desired.

Key Benefits and Actions:

  • Readily absorbed: Absorption of vitamin B12 is facilitated by intrinsic factor, a natural protein produced by the parietal cells of the stomach lining. It may also be absorbed by an alternate mechanism without reliance on intrinsic factor when high amounts of 1,000 mcg or more are taken. Thus, individuals without adequate intrinsic factor can still obtain adequate amounts of B12 if extra amounts are ingested.*
  • Active, coenzyme forms: Methylcobalamin is a body-ready form with metabolic benefits that may not be provided by other forms of vitamin B12. Methylcobalamin supports the formation of healthy red blood cells, immune and nervous system support, cognitive function, and homocysteine regulation.* Adenosylcobalamin is the mitochondrial form of B12 and supports energy metabolism and endurance levels.* Although cyanocobalamin is the most commonly used form of vitamin B12 in dietary supplements, it must be converted by enzymes into an active coenzyme form to be useful. Nutritional inadequacies, enzyme defects, and tissue abnormalities can reduce the body’s ability to synthesize the active forms of B12.*
