At 1,000 mcg per lozenge, **Methylcobalamin** lands right in the middle of the clinically studied range (250–5,000 mcg) for supporting energy, nerve function, and red blood cell production. The directions suggest 1–2 lozenges daily, giving you up to 2,000 mcg if you take two — plenty to maintain healthy B12 levels for most people.
The lozenge format is a practical choice here. You dissolve it in your mouth, which allows B12 to absorb through the oral mucosa — bypassing the gut, where absorption depends on intrinsic factor that naturally declines with age. This makes it especially relevant if you're over 50 or have digestive concerns. The form itself is the bioactive version your body can use directly, with no conversion step required.
If you're vegan or correcting a known deficiency, you may want to start at 2 lozenges daily. For maintenance, one lozenge provides a solid dose — though it sits at the lower end of what's typically supplemented.
