What is niacin?

Niacin is helpful for those with high cholesterol, as it can help flush cholesterol from the system.  However, that very ability can cause physical discomfort, and most people who want to take it must build up their endurance to its effects.  For example, niacin will cause actual flushing to the upper body, where those taking it will feel hot to the touch and have pink or even red skin on their torso, neck, and face.  This happens because niacin opens the blood vessels wider, allowing more blood flow.  It’s a healthy reaction, but it can be too much for some bodies.

Sometimes, niacin can flush something from the body which causes other reactions – like a mild rash or hives.  It can also speed up the heart rate.  If you’re hoping to lower your cholesterol with niacin, be sure to study up on it.  See a nutritionist for tips on how to safely build up your tolerance to it – and also be careful not to take more than your body can handle.  Most doctors would not suggest more than 500 milligrams of niacin a day – and be careful if you decide to take the timed-release version, as it can weaken your liver.

Other benefits of niacin include help with digestion, healthier skin, and increased blood flow to the heart.
