Cerefolin with NAC is prescribed to patients with neurovascular oxidative stress or high blood levels of homocysteine to increase or maintain levels of such nutrients as folate and vitamin B12, according to Drugs.com. It also contains an antioxidant that decreases oxidative stress and homocysteine levels.
Oxidative stress occurs when the body is not able to produce free radicals, which are oxygen molecules with unpaired electrons, or provide protection against the hazardous effects of free radicals, says Dr. Ananya Mandal of News Medical. The impact of this stress intensifies symptoms that occur in patients with such neurodegenerative diseases as Parkinson's disease, Alzheimer's disease, heart disorders and arthritis.
Homocysteine is an amino acid, a substance needed to create protein, which is naturally found in meat, says WebMD. Research suggests that high levels of homocysteine in the blood may lead to heart disease. However, other studies state that lowering these levels does not increase an individual's risk of developing heart disease. High levels of homocysteine are often accompanied by low levels of vitamins B6 and B12 as well as folate.
Individuals who are allergic to ingredients in Cerefolin with NAC or have a serious illness should not take the supplement, says Drugs.com. Individuals with such specific health issues as anemia, kidney stones, liver issues and ulcers should consult a physician before taking the supplement.
