Methylmalonic acid (MMA) is a byproduct of metabolism that is normally converted into succinyl-CoA, a molecule that plays a crucial role in energy production. Vitamin B12 is essential for this conversion process. When vitamin B12 levels are low, MMA accumulates in the blood and urine. Therefore, measuring MMA levels in urine can be a useful tool for diagnosing vitamin B12 deficiency. Also consider homocysteine as an alternative method of assessing an individual’s vitamin B12 requirements.
