You're getting 1,000 mcg of **Vitamin B12** per nugget — well within the typical supplement range of 250–5,000 mcg and far above the 2.4 mcg RDA, which matters because B12 absorption is notoriously inefficient. At this dose, you're covered for supporting energy metabolism, nerve function, and red blood cell production. The sublingual delivery (dissolved under the tongue) helps B12 bypass the gut and absorb directly into the bloodstream, which is especially useful if you have lower intrinsic factor levels — common in adults over 50 and anyone on acid-reducing medications.

The form here is cyanocobalamin — a synthetic version your body has to convert before it can use. It works, but the conversion adds an extra step compared to methylcobalamin or adenosylcobalamin, which are already in their active coenzyme forms. For most healthy people the difference is modest, but if you're supplementing specifically to address a deficiency or have methylation concerns, the active forms are a more direct route.

At one nugget per day, this is a straightforward B12 supplement at a moderate dose. If you're looking for higher-potency support — especially for energy or cognitive goals — you'd want to look at products in the 2,000–5,000 mcg range.
