For the dietary management of individuals with distinct nutritional needs under a physician or health-care provider's supervision for hyperhomocysteinemia; with particular emphasis for individuals with or at risk for atherosclerotic vascular disease in the coronary¹, peripheral², or cerebral³ vessels, or vitamin B₁₂ deficiency⁴. Niva-Fol™ Tablets are labeled as a medical food intended for use under active and ongoing medical supervision requiring medical care on a recurring basis for, among other things, instructions on the use of the medical food.

Medical foods are Intended for the dietary management of a patient who, because of therapeutic or chronic medical needs, has limited or impaired capacity to ingest, digest, absorb, or metabolize ordinary foodstuffs or certain nutrients, or who has other special medically determined nutrient requirements, the dietary management of which cannot be achieved by the modification of a normal diet alone. Although a medical-food product is intended for use under the active and ongoing medical supervision, FDA does not require a prescription.

Folacin (folic acid) when administered as a single agent in doses above 0.1 mg daily, may obscure pernicious anemia in that hematologic remission can occur while neurological manifestations remain progressive. The 2 mg of cyanocobalamin contained in Niva-Fol™ Tablets has been shown to provide an adequate amount of cyanocobalamin to address this precaution⁵. Unmetabolized folic acid has been shown in one study of 105 postmenopausal women (50-75 yrs) to have the potential to reduce natural killer cells' cytotoxicity, which may result in an impaired immune response⁶.

Cyanocobalamin should not be used in those with Leber's optic atrophy. Decreased levels of B₁₂ have been associated with reduced ability to detoxify the cyanide in exposed individuals and cyanocobalamin may increase the risk of irreversible neurological damage from optic atrophy in those affected with the disorder. Hydroxocobalamin can aid in the detoxification of cyanide. This form of B₁₂ is an acceptable form for B₁₂ supplementation in those with this disorder.

Pregnant women and nursing mothers should only use 12 microgram doses of B₁₂ (cyanocobalamin) from nutritional supplements. Doses higher than this should only be recommended by your physician. Administration of doses of vitamin B₁₂ greater than 10 micrograms daily may produce a hematological response in those with anemia secondary to folate deficiency.

If pregnant, or planning to become pregnant or are currently breast-feeding please contact your physician, or health-care provider before using or continuing use.

Allergic sensitization has been reported following both oral and parenteral administration of folacin (folic acid). Paresthesia, somnolence, nausea and headaches have been reported with pyridoxine. Mild transient diarrhea, polycythemia vera, itching, transitory exanthema, and the feeling of swelling of the entire body has been associated with cyanocobalamin.

Known hypersensitivity to any of the components in the product is a contraindication.

Pyridoxine supplements should not be given to patients receiving the drug levodopa, because the action of levodopa is antagonized by pyridoxine. However, pyridoxine may be used concurrently in patients receiving a preparation containing both carbidopa and levodopa. Concurrent use of phenytoin and folacin (folic acid) may result in decreased phenytoin effectiveness.
