B12 deficiency is surprisingly common — especially if you're vegan, over 50, or on acid-reducing medications — and the symptoms (fatigue, nerve tingling, brain fog) are easy to miss. At 1,500 mcg of **Methylcobalamin**, you're getting a solid dose within the 250–5,000 mcg supplemental range, in the active form your body can use without conversion.

The methylcobalamin form bypasses the liver processing that synthetic B12 requires, which matters if your conversion efficiency is reduced — something that naturally happens with aging.

If your B12 levels are already adequate, supplementing higher won't boost your energy. Your body simply excretes the excess. This is a targeted supplement for people at risk of deficiency, not a general energy pill.
