Vitamin B3.

Niacin is a form of vitamin B3. It is found in foods such as yeast, meat, fish, milk, eggs, green vegetables, and cereal grains. Niacin is also produced in the body from tryptophan, which is found in protein-containing food.

What are the benefits of vitamin B3?

The effectiveness ratings for NIACIN are as follows:

_Abnormal levels of cholesterol or blood fats (dyslipidemia). Some niacin products are approved by the U.S. Food and Drug Administration (FDA) as prescription products for treating abnormal levels of blood fats.

_A disease caused by niacin deficiency (pellagra). Niacin is approved by the U.S. Food and Drug Administration (FDA) for this use. However, niacin can cause “flushing” (redness, itching, and tingling).

So another product, called niacinamide, is sometimes preferred because it doesn’t cause this side effect.

_Abnormal levels of blood fats in people with HIV/AIDS. Taking niacin seems to improve levels of cholesterol and blood fats called triglycerides in patients with this condition.

_A grouping of symptoms that increase the risk of diabetes, heart disease, and stroke (metabolic syndrome).

_Taking niacin seems to increase levels of high-density lipoprotein (HDL or “good”) cholesterol and reduce levels of blood fats called triglycerides in people with metabolic syndrome. Taking the niacin along with a prescription omega-3 fatty acid seems to work even better.

Niacin is absorbed by the body when dissolved in water and taken by mouth. It is converted to niacinamide if taken in amounts greater than what is needed by the body.

Niacin is required for the proper function of fats and sugars in the body and to maintain healthy cells. At high doses, niacin might help people with heart disease because of its beneficial effects on clotting. It may also improve levels of a certain type of fat called triglycerides in the blood.

Niacin deficiency can cause a condition called pellagra, which causes skin irritation, diarrhea, and dementia.

People with poor diet, alcoholism, and some types of slow-growing tumors called carcinoid tumors might be at risk for niacin deficiency.

As with all B vitamins, niacin helps convert food into energy by aiding enzymes.

Specifically, niacin is a major component of NAD and NADP, two coenzymes involved in cellular metabolism.

Furthermore, it plays a role in cell signaling and making and repairing DNA, in addition to acting as an antioxidant.

These are some of the symptoms of niacin deficiency :





_Skin problems.

Severe niacin deficiency, or pellagra, mostly occurs in developing countries, where diets are not as varied.


In alternative medicine, niacin supplements are often touted as a natural remedy for the following health problems:


_Alzheimer’s disease.


_blood pressure.



_high cholesterol.


_motion sickness.

_memory problems.

_premenstrual syndrome.

_Additionally, niacin is used to slow the effects of aging, reduce stress, improve digestion, and stimulate circulation.
