Vitamin B3, or niacin, is a key nutrient that helps your body stay energised and healthy. It supports your brain, skin, digestion and even keeps your cholesterol in check. Not getting enough can leave you feeling tired, unfocused or noticing skin and stomach issues. This guide will help you understand what vitamin B3 niacin does, why it matters for your daily health and how to spot deficiency early so you can feel your best every day.
What is vitamin B3 (Niacin)?
Vitamin B3 is a water-soluble vitamin found naturally in many foods, added to some others and also available as a supplement. If you’re wondering what is vitamin B3 niacin, it exists in two main forms: nicotinic acid and nicotinamide and the body can also produce it from the amino acid tryptophan.
Vitamin B3 helps more than 400 enzymes function properly, supporting energy production, fat and cholesterol synthesis, DNA repair and protecting cells with its antioxidant effects. Any excess niacin is excreted through urine.
Role of vitamin B3 in health
Niacin plays a crucial role in your body by converting the food you eat into energy, keeping you active throughout the day. Its niacin vitamin uses include supporting key body systems such as the nervous system, digestion and skin health.
Niacin also helps maintain cholesterol balance by raising good HDL cholesterol, particularly when taken as a supplement and contributes to heart health by helping manage blood fats. However, taking too much niacin can cause side effects, so it is important to follow medical advice.
What are the benefits of vitamin B3 (Niacin)?
Vitamin B3 offers several important vitamin B3 niacin benefits for your health. It helps keep cholesterol levels in check and supports heart health. As an antioxidant, it can reduce inflammation and oxidative stress. Niacin also helps your body convert carbohydrates and fats into energy and prevents pellagra, a disease that affects the skin, digestion and mental health.
Additionally, it supports skin health, may protect against sun damage and helps maintain brain function. You can boost your intake through foods with vitamin B3 niacin, such as meat, fish, peanuts, eggs and whole grains.
Vitamin B3 deficiency & health risks
A lack of vitamin B3 can lead to health problems, most notably a condition called pellagra. Common vitamin B3 niacin deficiency symptoms include rough, red or scaly skin that may resemble sunburn, as well as tiredness, weakness or feelings of sadness.
Digestive issues such as diarrhoea and stomach problems are also common, along with cognitive effects like poor memory and difficulty focusing. Recognising these symptoms early is important to prevent more serious health complications.
How does health insurance help in cases of vitamin B3 deficiency?
Medical insurance policy can make managing a vitamin B3 deficiency easier by helping cover the costs of diagnosis and treatment. It may support expenses like doctor visits, blood tests and supplements prescribed to address niacin deficiency. However, the exact coverage can vary depending on your insurer and policy.
Some plans may also offer access to nutritional counselling, so it’s best to check your policy terms or speak with your insurer to understand what benefits are available.
