B-Complex Vitamins - Vitamins B3 (Niacin, Niacinamide, Nicotinic Acid)

Niacinamide has many of the same effect as niacin; but, for most purposes, is better because it does not cause the flushing of face which niacin will induce for several minutes.

Dosage: Niacinamide has many of the same effect as niacin; but, for most purposes, is better because it does not cause the flushing of face which niacin will induce for several minutes. Best use niacinamide to avoid face flush.

RDA 18 mg/ ODA 100 mg/ TDA 2,000-6,000 mg (time release). Mega-doses are up to 25,000 mg for schizophrenia, high cholesterol, and arteriosclerosis (but prolonged massive doses might induce stomach ulcers, jaundice, liver damage, colitis, and male impotence). Recommended: Take it with meals. Of patients given 1.5 grams daily of niacin for 26 weeks, 23% had lowered LDL (bad) cholesterol, and 33% had increased HDL (good) cholesterol. (However, some patients could not tolerate the face flushing.) Hundreds of patients with rheumatoid arthritis and osteoarthritis were given 900-4,000 mg of niacinamide in divided doses daily and experienced good results.

Deficiency Symptoms: Mild deficiency – canker sores, irritability, nervousness, diarrhea, insomnia, chronic headaches, digestive problems, and anemia. Severe – pellagra, neurasthenia, mental dullness, and disorientation. (The primary symptoms of pellagra are dermatitis, dementia, and diarrhea.)

Needed for Assimilation: Vitamin B complex and vitamin C

Interactions: The body converts tryptophan into niacin. Because niacin works closely with the other B vitamins, they all need to be taken at the same time.

Warning: Do not use sustained-release niacin; it can damage the liver. (In one test, 52% taking it experienced liver damage.) Instead, gradually increase dosage of regular pure crystalline niacin over 4-6 weeks (from 100 mg 3 times daily, to 1.5-3 grams daily in divided doses). Inositol hexaniacinate is the safest form of niacin currently taken. Niacin should not be used in advanced diabetes or for those with pre-existing liver disease.
