What is methylmalonic acid?
Methylmalonic acid is produced in small amounts in the body and is necessary for metabolism and energy production. Vitamin B12 promotes the conversion of methylmalonyl CoA to succinyl Coenzyme A. If there is not enough vitamin B12 available in your body, then the concentration of methylmalonic acid begins to rise, increasing in the blood and urine.
Why measure methylmalonic acid?
Measuring raised methylmalonic acid levels in your blood or urine is a sensitive early indicator of a vitamin B12 deficiency. Vitamin B12 deficiency symptoms usually develop gradually but can worsen if the condition goes untreated. Symptoms of vitamin B12 deficiency include feeling faint, pale skin, and heart palpitations.
