Vitamin B3 includes two main forms: niacin (nicotinic acid) and niacinamide (nicotinamide). Both play important roles in the human body. Below is some information on the role, effectiveness and contraindications of vitamin B3 supplements:
Role of Vitamin B3:

Energy metabolism: Vitamin B3 is involved in energy metabolism, helping to convert food into energy.

Nervous system: Plays a role in maintaining the health of the nervous system.

DNA synthesis: Participates in DNA synthesis.

Antioxidant Functions: Niacin has antioxidant properties that can help protect cells from damage caused by free radicals.

Vitamin B3 supplements:

Vitamin B3 supplements can be used to address nutritional deficiencies or to treat specific medical conditions. Some reasons why people might take vitamin B3 supplements include:

Hyperlipidemia: Niacin may be prescribed to lower LDL cholesterol (“bad cholesterol”) and raise HDL cholesterol (“good cholesterol”) levels.

Pellagra: A condition caused by niacin deficiency, which can occur in people with extremely poor diets.

Energy support: To deal with stressful or tired situations.


The effectiveness of vitamin B3 supplements depends on individual needs and the presence of deficiencies. Niacin has been extensively studied for its effects on cardiovascular health, but it is important to follow your doctor's directions to avoid side effects.

Side effects: Taking high doses of niacin can cause side effects such as skin redness (flushing), itching and gastrointestinal problems.

Drug interactions: Niacin can interact with some medications, so it is important to tell your doctor if you are taking other medications.

Liver problems: Some people with liver problems should avoid high doses of niacin, as it may affect liver function.

Allergies: Some people may be allergic to niacin or niacinamide.

Before taking vitamin B3 supplements, it is advisable to consult a health professional to determine whether they are necessary and for guidance on the appropriate dose. Self-medicating with high doses of niacin may pose health risks.
