Vitamin B12 is essential to numerous processes throughout the body, and while it's available in several forms in nutritional supplements, clinical evidence shows the body uses methylcobalamin more efficiently than other forms, such as cyanocobalamin. Thorne's Vitamin B12 provides this vitamin in its active, tissue-ready methylcobalamin form for optimal utilization.

This formula supports healthy nerve function and feeling, promotes the body's methylation pathways, helps balance circadian rhythms for more restful sleep, and supports healthy homocysteine levels, cardiovascular health, and cognitive function. It's especially beneficial for vegans and vegetarians whose diets tend to be low in B12, individuals with low stomach acid, elderly adults who may eat fewer B12-rich foods or absorb it less efficiently, anyone with anemia (since B12 plays a key role in red blood cell formation), and those taking medications such as metformin, proton pump inhibitors, or seizure medications that can affect B12 levels.
