Vitamin ~ Niacin
This B vitamin has been in the limelight as a potent cholesterol lowering agent that rivals some prescription drugs in effectiveness.But niacin in its various forms also shows promise in the prevention and treatment of depression, arthritis, and a host of other ailments.
| COMMON USES |
WHAT IT IS |
FOUND IN HERBALIFE PRODUCTS
|
- Lowers cholesterol.
- May improve circulation.
- May ease symptoms of arthritis.
- May relieve depression.
- May prevent progression of type 1 diabetes.
| Also known as vitamin B3, niacin is available as a supplement in three forms: nicotinic acid (or nicotinate), niacinamide, and inositol hexaniacinate (niacin bound to inositol, a member of the B-vitamin family).The body can also make niacin by converting the amino acid tryptophan - found in eggs, milk , and poultry - into the vitamin.About half of the niacin supplied by the average diet comes from the body's processing of tryptophan. In supplement form, both nicotinic acid and niacinamide can satisfy your nutritional requirement for this B vitamin, but each of the three forms has its own specific role in treating disease. | PROTEIN SHAKES

LATEST FINDINGS
| | Tablet
Capsule
| Niacin is needed to release energy from carbohydrates.It is also involved in controlling blood sugar, keeping skin healthy, and maintaining the proper functioning of the nervous and digestive systems.
| In a study of niacin's effect on high cholesterol, participants, who took niacin supplements had a 17% drop in LDL ("bad") cholesterol levels, a 16% rise in HDL ("good") cholesterol levels, and an 18% reduction in triglyceride levels.
In a study of niacinamide's effect on osteoarthritis, researchers found that people who took the supplement for 12 weeks experienced more joint flexibility, less inflammation, and less need for anti-inflammation , and less need for anti-inflammatory drugs than those who had a placebo. |
| CAUTION! |
PREVENTION |
ADDITIONAL BENEFITS
| | Consult your doctor before using any form of niacin if you have any of the following conditions; diabetes, low blood pressure, bleeding problems, glaucoma, gout, liver disease, or ulcers.All can be aggravated by niacin.
If you take a daily therapeutic dose of 1,000 mg or more of any form of niacin, see a doctor every three months to have your liver enzymes measured.
Reminder: If you have a medical condition, talk to your doctor before taking supplements.
| High doses of niacin raise HDL ("good") cholesterol, while lowering LDL ("bad") cholesterol and triglyceride levels.In fact, studies show that niacin may be more effective than prescription cholesterol-lowering drugs in reducing the risk of heart disease, mainly because it is one of the few agents known to boost HDL.The cholesterol-lowering forms of niacin are nicotinic acid and inositol hexaniacinate.Although both are effective, inositol hexaniacinate is a safer form to use because it doesn't cause skin flushing and is less likely to cause liver damage.
| Niacin relaxes blood vessels, and so is useful for circulatory problems, such as intermittent claudication (a painful cramping in the calf caused by poor blood circulation that often occurs after walking), and Raynaud's disease (a disorder characterized by numbness and often pain in the hands or feet when exposed to cold).Inositol hexaniacinate is the preferred form to use for these conditions. Niacin also helps foster healthy brain and nerve cells, and some evidence indicates that niacinamide can ease depression, anxiety, and insomnia.Niacinamide seems to have an anti-inflammatory effect, which may benefit those with rheumatoid arthritis; it may also help heal damaged cartilage, potentially valuable for osteoarthritis.High doses of niacinamide may reverse the development of type 1 diabetes - the form that typically appears before age 30 - if it is given early enough.This therapy should be tried only with medical supervision. |
| HOW MUCH YOU NEED |
IF YOU GET TOO LITTLE |
IF YOU GET TOO MUCH
| | The RDA for niacin is 14 mg for women and 16 mg for men daily.But far higher doses are required to lower cholesterol and treat other disorders.
| A slight niacin deficiency will cause patches of irritated skin, appetite loss, indigestion, and weakness.Severe deficiencies (practically nonexistent in industrialized countries) result in pellagra, a debilitating disease.Symptoms include a rash in areas exposed to sunlight, vomiting, a bright red tongue, fatigue, and memory loss.
| Therapeutic doses of nicotinic acid may cause stomach upset, flushing and itching of the skin, and liver damage (at high doses, niacinamide may also harm the liver).To prevent these side effects, substitute inositol hexaniacinate whenever possible: It eliminates skin flushing and greatly reduces the risk of liver damage. But if you're taking any form of niacin for long periods, have your doctor do periodic blood tests to monitor your liver.Doses of inositol hexaniacinate higher than 2000 mg a day may have a blood-thinning effect. |

GUIDELINES FOR USE
| | Niacin is found in foods high in protein, such as chicken, beef, fish, and nuts.Breads, cereals, and pasta are also enriched with niacin.Though they're low in niacin, milk and other dairy products, as well as eggs, are good source of the vitamin because they're high in tryptophan.
| Pasta is often enriched with niacin. But you'd have to chow down 7 cups of cooked pasta to meet the RDA for this vitamin.
| Take any form of niacin with meals or milk to decrease the likelihood of stomach upset.Do not take therapeutic doses or any form of niacin if you take cholesterol-lowering prescription drugs.
