VITAMIN B9 REGULATION: The Federal Register Notices from 1971 to 1973 established that increased vitamin B9 was proper therapy in megaloblastic anemias of tropical and nontropical sprue, nutritional origin, pregnancy, infancy and childhood. Vitamin 9 metabolism can be affected by malabsorption issues which differ widely among population groups. The March 5, 1996 Federal Register Notice (61 FR 8760) states that "The agency concluded that the scientific literature did not support the superiority of any one source of vitamin B9 over others, and that the data were insufficient to provide a basis for stating that a specific amount of vitamin B9 is more effective than another amount [emphasis added]." The actual amount and source of vitamin B9 require a licensed medical practitioner's supervision to achieve a satisfactory maintenance level, and may exceed the 0.8 mg UL. The Federal Register Notice of August 2, 1973 (38 FR 20750) specifically states that "dietary supplement preparations are available without a prescription (21 CFR 121.1134). Levels higher than dietary supplement amounts are available only with a prescription. Oral preparations supplying more than 0.8 mg of vitamin B9 per dosage unit would be restricted to prescription dispensing and that a dietary supplement furnishing 0.8 mg could be prescribed when a maintenance level of 0.8 mg per day was indicated. When clinical symptoms have subsided and the blood picture and/or CSF vitamin B9 levels have become normal, a maintenance level should be used. Patients should be kept under close supervision and adjustment of the maintenance level made if relapse appears imminent. In the presence of alcoholism, hemolytic anemia, anticonvulsant therapy, or chronic infection, the maintenance level may need to be increased [emphasis added]." However, once the level of active vitamin B9 exceeds 0.8 mg - as prescribed dosages, then the product is no longer a medical food but a dietary management / prescription (Rx)-vitamin B9 regardless of pregnancy/lactation status in spite of the fact that folic acid - including reduced forms, may be added to medical foods as defined in section 5(b)(3) of the Orphan Drug Act (21 USC 360ee(b)(3)), or to food (21 CFR 172.345). In the Letter Regarding Dietary Supplement Health Claim for Folic Acid, Vitamin B6, and Vitamin B12 and Vascular Disease (Docket No. 99P-3029) dated November 28, 2000, FDA wrote "... high intakes of vitamin B9 may partially and temporarily correct pernicious anemia while the neurological damage of vitamin B12 deficiency progresses. IOM/NAS (1998) set the UL for all adults of 1 mg per day because of devastating and irreversible neurological consequences of vitamin B12 deficiency, the data suggesting that pernicious anemia may develop at a younger age in some racial or ethnic groups, and the uncertainty about the extent of the occurrence of vitamin B12 deficiency in younger age groups (IOM/NAS, 1998) [emphasis added]." Summary: This product is a dietary management product that - due to advanced vitamin B9 levels, requires administration under the care of a licensed medical practitioner, and the most appropriate way to do that is to provide the product as prescription for pedigree reporting and safety monitoring. The ingredients, indication or claims of this product are not to be construed to be drug claims.

VITAMIN B9 MECHANISM OF ACTION: Vitamin B9 is essential for the production of certain coenzymes in many metabolic systems such as purine and pyrimidine synthesis. It is also essential in the synthesis and maintenance of nucleoprotein in erythropoiesis. It also promotes white blood cell (WBC) and platelet production in vitamin B9-deficiency anemia. Vitamin B9 is associated with methylation and transformylation biochemistry.
INTERACTIONS: Talk to your healthcare practitioner and/or pharmacist before taking or using any prescription or over-the-counter medicines or herbal/health supplements alongside this product.
ADVERSE REACTIONS: Allergic reactions have been reported following the use of oral and parenteral vitamin B9. Mild transient diarrhea, polycythemia vera, itching, transitory exanthema and the feeling of swelling of the entire body has been associated with cobalamin. Nausea, vomiting, diarrhea, transient skin rash, flushing, epigastric pain, and constipation have been associated with acetylcysteine.
Call your medical practitioner about side effects.
CONTRAINDICATIONS: This product is contraindicated in patients with a known hypersensitivity to any of the components contained in this product.
WARNINGS: Caution is recommended in patients with a history of bipolar illness. Mood elevation is possible in this population.
Caution is also recommended in patients taking anticonvulsant medications as vitamin B9 may interfere with anticonvulsant medication, and may lower seizure threshold.
Patients undergoing cancer treatment should consult their licensed medical practitioner for advice.
PRECAUTIONS: Vitamin B9 alone is improper therapy in the treatment of pernicious anemia and other megaloblastic anemias where vitamin B12 is deficient. Vitamin B9 in doses above 0.1 mg daily may obscure pernicious anemia in that hematologic remission may occur while neurological manifestations progress.
PREGNANCY and NURSING MOTHERS: This product is not intended for use as a prenatal/postnatal multivitamin for lactating and non-lactating mothers. This product contains B vitamins plus NAC. Talk with your medical practitioner before using if pregnant or lactating.
HOW SUPPLIED: Levomefolate Calcium/Acetylcysteine/Mecobalamin/Algal Powder (6 mg-600 mg-2 mg-90.314 mg) is supplied as a coated, gray caplet debossed "V324", dispensed in bottles of 1000 caplets.
†This product is a prescription-vitamin B9 with or without other dietary ingredients that - due to increased vitamin B9 levels (AUG 2 1973 FR 20750), requires an Rx on the label because of increased risk associated with masking of B12 deficiency (pernicious anemia). Based on our assessment of the risk of obscuring pernicious anemia, this product requires licensed medical supervision, an Rx status, and a National Drug Code (NDC) - or similar product code, as required by pedigree reporting requirements and supply-chain control as well as - in some cases, for insurance-reimbursement applications.
