Its primary purpose is to assist the body in making two key coenzymes, NAD and NADP, both necessary in the synthesis of energy and normal cell operation.

• NAD: Assists in turning food into energy within the body.
• NADP: Aids in the construction of molecules and the safeguarding of cells.

FAQs

1. What is the benefit of B3 vitamin?

Vitamin B3 (Niacin) is an essential nutrient that serves as a precursor to the coenzymes NAD and NADP, which are involved in hundreds of biochemical reactions in the body. Its key benefits include supporting energy production by helping convert carbohydrates, fats, and proteins into ATP (the body’s main energy source), promoting heart health by improving cholesterol levels (lowering LDL and triglycerides while increasing HDL), supporting brain function by aiding energy supply and repair processes, and contributing to DNA repair by assisting enzymes that maintain genetic stability.

2. What are the symptoms of lack of vitamin B3?

A deficiency of Vitamin B3 can start with mild symptoms such as fatigue and brain fog, but severe deficiency leads to a condition called Pellagra, which is characterized by the “three Ds.” These include dermatitis (a thick, scaly, pigmented rash often on sun-exposed areas like the neck), diarrhoea (digestive issues such as vomiting, abdominal pain, and inflammation of the tongue), and dementia (neurological symptoms like headaches, insomnia, memory loss, depression, and in advanced cases, hallucinations).

3. Does vitamin B3 brighten skin?

Vitamin B3 can help brighten the skin, especially when used in the form of niacinamide. It works by inhibiting the transfer of melanin to skin cells, which helps reduce dark spots and even out skin tone, strengthening the skin barrier by increasing ceramide production to retain moisture and improve radiance, and reducing redness due to its anti-inflammatory properties, making the skin appear clearer and more balanced.

4. What happens if you take vitamin B3 every day?

Taking Vitamin B3 daily is generally safe when kept within the recommended intake of about 14–16 mg for most adults, but higher doses can lead to noticeable effects. A common side effect is the “niacin flush,” where the skin becomes red, warm, and itchy temporarily due to widened blood vessels. Very high doses (above 1,000–2,000 mg per day) may cause toxicity, including liver strain, stomach ulcers, and changes in blood sugar levels. Additionally, recent research suggests that excessive levels of certain niacin metabolites may contribute to arterial inflammation, highlighting the importance of staying within safe dosage limits.
