B12 Elite, 60 vegetarian lozenges

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 sLife Extension'sces, so those following a vegetarian diet may not get enough.

Life Extension's new B12 Elite combines two types of cobalamin: adenosylcobalamin and methylcobalamin. These are “active” forms—meaning yLife Extension's 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 yLife Extension's 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.
