In plain English

Infants with severe vitamin B12 deficiency show measurable improvement in neurological function and blood markers after receiving vitamin B12 supplementation.

See the scientific wording

Clinical improvement in neurological symptoms and hematologic parameters occurs following vitamin B12 supplementation in infants with severe deficiency, suggesting partial reversibility of early-stage damage.

Why this might work

When a baby lacks vitamin B12, their body cannot make enough healthy red blood cells or properly insulate nerve fibers. Giving vitamin B12 fixes both problems: it lets the bone marrow produce normal red blood cells again and allows the brain to repair damaged nerve coverings, which improves energy, movement, and awareness.

    When a baby doesn't get enough vitamin B12, they can get very tired, weak, and have bad blood, but giving them B12 supplements helped them feel better — showing that fixing the problem early can undo some of the harm.
