Nicotinic acid or niacin, the water-soluble B vitamin, improves all lipoproteins when given in doses well above the vitamin requirement.
Most experts recommend starting with the immediate-release form.
Nicotinic acid is inexpensive and is available without a prescription, but your doctor must monitor you because of potential side effects. Because the dose needed is about 100 times more than the Recommended Dietary Allowance for niacin and can be potentially toxic, the drug must always be taken under a doctor s care and never self-prescribed. A common and troublesome side effect of nicotinic acid is flushing or hot flashes, which are the result of the widening of blood vessels. Most patients develop a tolerance to flushing. If you are taking high blood pressure medication, it is important to set up a blood pressure monitoring system while you are getting used to your new niacin regimen.
