Cerefolin is the brand name for L-methylfolate, a man-made form of the B-vitamin folate. Cerefolin NAC is a combination of folate and N-acetylcysteine, an amino acid derivative of L-cysteine, according to Drugs.com.
L-methyfolate, or folic acid, may be taken as a vitamin supplement or to prevent fetal neural tube defects when pregnant and to prevent tropical sprue. It also treats certain medical conditions, such as inadequate folic acid and anemia from inadequate folic acid. It is advisable to take folate by mouth, with or without food, usually once per day, according to WebMD. Levomefolate and methyltetrahydrofolate are other names for forms of folic acid supplements.
Combined with NAC, Cerefolin helps to lower or eliminate oxidative stress and reduce homocysteine levels, reports Drugs.com. The body produces homocysteine whenever it chemically alters adenosine, a nucleoside occurring naturally in the body. People with a genetic condition called homocystinuria often have elevated levels of homocysteine, states MedicineNet. This can potentially lead to blood clots and the hardening of blood vessels.
As of 2015, N-acetylcysteine is possibly effective for treating lung disease, preventing complications of COPD, treating some types of epilepsy seizures, reducing flu symptoms, preventing side effects from certain kinds of cancer treatments, treating angina and preventing heart attack or stroke in people with kidney disease, as claimed by WebMD.
