Vitamin B12 is essential for brain health and function, energy metabolism and the production of red blood cells. B12 Elite combines two active forms of this crucial vitamin in a single vegetarian lozenge.

What Is B12 Elite?


Vitamin B12 is essential for proper biological processes. Serum levels of vitamin B12 can decline over time, and because it’s found primarily in animal products, vegetarian diets may not provide sufficient B12. Our B12 Elite gives you 500 mcg each of adenosylcobalamin and methylcobalamin: two neurologically active forms of B12.


B12 Elite combines two forms of this vitamin—both of which are essential for proper bodily and neurological function.

B12 Elite Benefits

  • Novel formula delivers two forms of bioactive B12
  • Helps protect delicate brain cells
  • Promotes healthy dopamine levels
  • Encourages healthy B12 serum levels
  • Promotes overall brain health



Two Active Forms of Vitamin B12


Vitamin B12 (also called cobalamin) is a water-soluble vitamin that plays a vital role in the health of your nervous system, blood cells and even your DNA (B12 helps protect delicate parts of your chromosomes). Our B12 Elite formula includes two bioactive forms of cobalamin that make it easier for your body to absorb and access vitamin B12’s health benefits.

Why Should I Supplement With B12 Elite?

Whether it's promoting brain health, supporting the nervous system or maintaining cellular health and energy levels, vitamin B12 is essential for us to thrive. But while this vitamin is excellent for our health, more and more of us are finding less and less in our systems because we don't produce it naturally. Changes in eating habits, like relying more on plant-based diets, along with the one thing we can’t change, the passage of time, are also impacting the levels of this vital nutrient.

Luckily, our experts saw the need and formulated our B12 Elite to help you fill in any of your gaps. We didn't just throw any old form of the vitamin in there. B12 Elite uses the active forms of B12. So it's easier for your body to absorb and access the health benefits right away. This tasty vegetarian lozenge has no artificial flavors, colors or sweeteners, and has absolutely no added sugar.

So start promoting your brain health, nervous system, blood cells and more with B12 Elite from Life Extension.

Vitamin B12 is good for you. But many people don’t get sufficient B12 from their diets alone. Reasons range from age-related insufficiency to dietary intake: B12 comes primarily from animal sources, so those following a vegetarian diet may not get enough.

Our new B12 Elite combines two types of cobalamin: adenosylcobalamin and methylcobalamin. These are “active” forms—meaning your body can make use of them right away.

Adenosylcobalamin helps preserve neuronal function

Leucine-Rich Repeat Kinase 2 (LRRK2) is a type of enzyme that modifies other proteins by adding phosphate groups.1 Inhibiting the activity of this enzyme has been associated with helping to preserve neuronal tissue.2

A series of preclinical studies has shown that the adenosylcobalamin form of B12 can inhibit the activity of multiple LRRK2 variants in neurons by decreasing phosphorylation (the addition of phosphate groups to amino acids).3

These studies found that adenosylcobalamin helped regulate healthy release of dopamine, a neurotransmitter that plays an important role in cognitive functions such as motor control, arousal, reinforcement and reward.3-6

A cofactor for energy metabolism

Adenosylcobalamin is active in the mitochondria, the powerhouses of your cells. It’s required as a cofactor for the synthesis of succinyl-CoA, a compound that supports cellular energy metabolism.7-9

Methylcobalamin for cellular health & beyond

Methylcobalamin is another neurologically active form of B12 (though in different ways than adenosylcobalamin). Methylcobalamin supports the central nervous system, and it’s essential for the replication and growth of cells.10

Methylcobalamin helps to maintain already healthy homocysteine levels.11-14 Inhibiting excess levels of this compound is key to maintaining healthy cardiovascular and neurological function.

B12 for a healthy brain and more

This B12 formula combines methylcobalamin and adenosylcobalamin to offer optimal cognitive support. Want the health benefits of the full range of the B vitamins? We also offer our BioActive Complete B-Complex formula: a wide-spectrum of B vitamins for whole-body health.
