Niacin is a naturally occurring water-soluble B vitamin used to help lower bad cholesterol (LDL) levels and triglycerides while increasing good cholesterol (HDL). By regulating these levels, this vitamin helps manage and prevent cardiovascular problems.

Niacin, also known as vitamin B3, contains nicotinic acid and nicotinamide which help form coenzymes necessary for energy production and regulating biological functions. Thanks to vitamin B3’s importance in regulating functions, taking Niacin can help regulate cholesterol levels in your blood.

Research has also found that Niacin may be neuroprotective and could help improve symptoms related to neuropathological conditions and neurodegenerative diseases such as Alzheimer’s.

Uses and Dosage

Doses of niacin prescribed will vary depending on the individual being treated. Follow your doctor’s directives and read all instructions on the vitamin’s packaging.

  • Swallow the tablet whole

  • Adults usually start by taking 250mg once daily
  • Adults are not recommended to take more than 6g a day
  • Taking aspirin or an NSAID before niacin can help reduce flushing

Avoid drinking alcohol or hot beverages shortly after taking your Niacin dose because it can cause an increase in side effects. These interactions should lessen or disappear as you continue to take this vitamin. Alcohol can also increase your risk of liver damage.

Why does Niacin cause flushing?

Some may experience temporary flushing right after taking a dose of niacin. This occurs because of nicotinic acid which causes blood vessels to widen in your skin. Flushing may occur at the beginning of treatment or when increasing your niacin dose.

How long does Niacin stay in the human system?

Niacin should leave your system within 2 to 4 hours after your last dose. This vitamin is water-soluble, meaning it is absorbed into your body’s tissues and is not stored in the body. Thanks to this, Niacin has a short half-life of 20 to 45 minutes. Half-life means the amount of time it takes for a drug to decrease by half.
