If you're looking to maintain your B12 levels, this lozenge delivers 500 mcg of **Methylcobalamin** — the active form your body can use directly without conversion. At 500 mcg, you're comfortably within the clinical supplementation range of 250–5,000 mcg, making this a reasonable maintenance dose for everyday support of energy and nerve function.

The lozenge format dissolves in your mouth, which allows for some sublingual absorption — a useful advantage for B12 since stomach acid and intrinsic factor can limit how much you absorb from a standard swallowed pill.

If you're addressing a confirmed deficiency or have absorption issues (common after age 50 or with certain medications), 500 mcg may not be enough for your needs. Clinical protocols for deficiency correction typically start at 1,000 mcg or higher.
