MMA-based cobalamin insensitivity index

MMA-based cobalamin insensitivity index is associated with biological aging acceleration in humans.

“Both cobalamin insensitivity indices were robustly associated with biological aging acceleration in a dose-response pattern (each p < 0.001).”

HumansCobalamin insensitivity index based on serum cobalamin multiplied by serum methylmalonic acidn = 22,812
