Causes of high MMA include: B12 deficiency, most often due to a B12-poor diet, issues with nutrient absorption, or drugs that deplete B12 levels (e.g. metformin) [2, 28] Poor kidney function. Kidneys that are not working properly can’t filter MMA into the urine, causing it to accumulate in the blood Methylmalonic acid is an organic acid and abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7. 35.

Methylmalonate (Genova) Optimal Result: 0 - 2.3 mcg/mg creatinine. Methylmalonic acid (MMA) is a substance produced in very small amounts and is necessary for human metabolism and energy production. In one step of metabolism, vitamin B12 promotes the conversion of methylmalonyl CoA (a form of MMA) to succinyl Coenzyme A. 2003-07-01 Methylmalonic acid is a dicarboxylic acid that is malonic acid in which one of the methylene hydrogens is substituted by a methyl group. It has a role as a human metabolite. It derives from a malonic acid.It is a conjugate acid of a methylmalonate(1-).
