Niacin, also known as Nicotinic Acid, is a water-soluble vitamin that has numerous health benefits. It is part of the vitamin B family and is essential for maintaining general health. Nicotinic acid is effective in managing cholesterol levels, reducing inflammation, and helping with mental focus. It can also help maintain normal blood sugar levels and support cognitive function.

Niacin is a vital nutrient for the body, as it is necessary for energy production and other metabolic processes. It can be obtained from a variety of sources, including dietary sources such as meats, eggs, fish, and legumes, or through supplementation. Upon ingestion of niacin, which is soluble in water, it is converted to its active form, niacinamide, and absorbed into the body.

Niaspan is a prescription medication used to reduce the risk of a heart attack in individuals with high cholesterol and a history of heart attacks. It can also be used in combination with other cholesterol-lowering medications to slow down the accumulation of fatty deposits in arteries.

Uses and Dosage

Nicotinic Acid is available in the form of Regular Release Tablets and should be taken orally with a low-fat meal or snack as prescribed by a physician. The recommended dosage of Nicotinic Acid is 1-3 times a day. Taking this medication on an empty stomach can increase the risk of side effects such as flushing and upset stomach.

You need to swallow extended-release Nicotinic Acid tablets whole, without crushing or chewing them, as this can cause the entire dose to be released at once and increase the risk of side effects. Make sure to swallow the whole or split tablet without crushing or chewing.

The dosage of Nicotinic Acid is determined based on the individual's medical condition and response to treatment. If taking this medication to treat lipid disorders, the dose should be started at a low level and gradually increased to minimize the risk of side effects. If switching from another niacin product, the dose must be increased slowly and according to the doctor's instructions.

If you are taking niacin to treat pellagra, the recommended dose is one tablet twice daily. For people with high cholesterol and triglyceride levels, the initial dosage of Nicotinic Acid is one tablet three times a day, with an increase of one tablet every four days until a maximum daily dose of 12-18 tablets is reached or as directed by a doctor.
