Xiaogang Li, Ph.D., an associate professor of Nephrology and Hypertension and a member of the KU Kidney Institute, found that vitamin B3 helped naturally inhibited the activity of a protein called Sirt1 that influences the formation and growth of cysts. Li and colleagues were able to show that vitamin B3 slowed the creation of cysts and restored kidney function in mice with PKD. The results were published in the June 17, 2013Journal of Clinical Investigation
Vitamin B3 or Niacin vs Niacinamide
Vitamin B3 is an essential vitamin required for processing fat in the body, lowering cholesterol levels, and regulating blood sugar levels. Recently it was discovered that B3 could decrease PKD cyst formation.
Niacinamide is a reduced form of Niacin without much flushing effect. Niacin does give flushing (skin gets red, you feel hot) and niacin lowers cholesterol. A slight deficiency of niacin can lead to irritability, poor concentration, anxiety, fatigue, restlessness, apathy, and depression. An overdose of niacin can lead to skin rashes, dry skin, various digestive problems. Long term overdose can lead to liver damage, elevated blood sugar as well as increased risk of birth defects.
Side effectsReactions range from flushing, itching, nervousness and headaches to intestinal cramps, nausea, and diarrhea. High doses of niacin can cause liver toxicity; doses in excess of 3 grams a day should be used only under c areful medical supervision (for example, in the treatment of high cholesterol). Gout, abnormal heart rhythms and worsening of stomach ulcers side effects have also been reported with very high doses of supplemental vitamin B3.
Caution with NiacinIt is rare but sometimes liver failure can occur with individuals who take niacin. On the web niacin is touted as a way to pass a urine drug test. Wait for your doctor to recommend taking B3. One individual with PKD/severe PLD had a bad reaction to B3.
Alcohol and B VitaminsAlcohol intake depletes B vitamins and minerals. During pregnancy extra B is needed for the pregnancy. PKD researchers at KU in the USA feel that possibly Vitamin B3 may hold promise for not only the treatment of PKD but for women possibly pregnant with a child that may have PKD.
Women should have 15 milligrams each day and men should have 15 to 19 milligrams each day. Tryptophan is an amino acid
that serves as a Vitamin B3 equivalent. Sixty milligrams of tryptophan is equal to 1 milligram of vitamin B3.
Corn is a great source of Vitamin B3 but limestone, the mineral, is needed to help release vitamin B3 in corn.
