Vitamin B3, commonly known as niacin, is a key nutrient that helps convert food into energy, supports brain function, and keeps your skin and nerves in top condition. So, what happens when your body doesn’t get enough of this important vitamin?
A vitamin B3 deficiency can result in conditions such as pellagra—which is marked by dermatitis, dementia, and digestive disturbances. It also leads to fatigue, skin problems, and more serious issues. However, you can be better equipped to take control of your health once you understand the causes and how to treat it.
Let’s take a look at what role vitamin B3 plays in our health and how it functions.
Role and Functions of Vitamin B3
Vitamin B3, also known as niacin, exists in two primary chemical forms: nicotinic acid and nicotinamide. These forms help in several vital processes in our bodies.
- One of the key roles of Vitamin B3 is it helps convert the food we eat into the energy our cells need to function.
- It’s also helpful for metabolism, allowing your cells to break down fats, carbohydrates, and proteins.
- Beyond that, vitamin B3 helps in DNA repair as it ensures your cells can heal and grow properly.
Vitamin B3 also forms NAD (nicotinamide adenine dinucleotide) and NADPH (nicotinamide adenine dinucleotide phosphate). These two molecules are crucial for various cellular reactions, such as the synthesis of fatty acids and cholesterol, as well as the production of neurotransmitters. Without niacin, our cells would struggle to produce the energy and biochemical components necessary for our health.
But, why exactly do you need vitamin B3 daily? With adequate levels of Vitamin B3, your body can support daily metabolic activities. Adequate Vitamin B3 also supports cholesterol management, heart health, and mental well-being.
So, how can we get niacin in our daily diet? You can find many natural sources of niacin like dried yeast, liver, red meat, poultry, fish, legumes, whole-grain cereals, enriched bread, and dairy products.
Sources of Vitamin B3
Let's explore some of the richest sources of Vitamin B3 and tryptophan, according to this report.
-
Animal-Based Sources of Vitamin B3
- Poultry: Chicken and turkey are packed with niacin. A 3-ounce serving of skinless chicken breast provides 10.3 mg, and turkey breast follows closely with 10 mg.
- Fish: Varieties like salmon, tuna, mackerel, and anchovies are excellent choices. For instance, a 3-ounce serving of sockeye salmon or canned tuna provides about 8.3 mg of niacin.
- Other Animal Sources: Dairy products like milk (0.2) and yogurt (0.3) provide tryptophan, which your body can convert into niacin.
-
Plant-Based Sources of Vitamin B3
- Nuts and Seeds: Peanuts, sunflower seeds, and almonds are nutritious snacks high in niacin. Dry-roasted peanuts offer about 4.2 mg of niacin per ounce, while dry-roasted sunflower seeds offer 2.0 mg of niacin per ounce.
- Cereals: Fortified cereals are great for niacin intake. Breakfast cereals fortified with 25% DV niacin offer 4.0 mg of vitamin B3.

Tips for Incorporating Niacin in Your Diet
To ensure you're getting enough vitamin B3, try to incorporate a mix of these foods into your diet. Cooking methods can affect the niacin content, so be mindful of grilling, baking, or steaming meats and fish to help retain niacin.
Vitamin B3 deficiency, or a lack of niacin, can happen for several reasons. You can avoid potential health issues by understanding these causes.
Causes of Vitamin B3 Deficiency
The reasons for deficiency can be broadly categorized into dietary causes and secondary causes associated with other conditions and medications.
-
Common Dietary Causes
One of the most common causes is related to diet. Diets high in corn or maize have shown higher rates of niacin deficiency. Maize naturally contains low levels of niacin and tryptophan, and our body cannot readily absorb its niacin unless we process maize through traditional methods.
-
Secondary Factors
Various conditions can contribute to niacin deficiency by impairing the body's ability to absorb or metabolize niacin. Secondary deficiencies in other vitamins, like B2 (riboflavin) and B6 (pyridoxine), can impact your niacin levels. These vitamins play key roles in converting tryptophan into niacin.
Certain health conditions can also further complicate our body’s ability to absorb niacin.
- Chronic alcohol use disorder is often linked to a deficiency in vitamin B3. Alcohol interferes with nutrient absorption and depletes essential vitamins from your body.
- People with gastrointestinal issues, like Crohn’s disease or chronic diarrhea, may have trouble absorbing nutrients.
- Certain drugs, such as those used to treat tuberculosis or specific immunosuppressants, can interfere with your body’s ability to produce or absorb vitamin B3.
Understanding how essential healthy eating habits and the right nutrition is the first step towards a better lifestyle. Take a look at this blog that discusses the power of healthy food choices and tips on maintaining your overall wellness.
A vitamin B3 deficiency can show up in various ways. You may miss some signs if you don’t know what to look for.
Symptoms of Vitamin B3 Deficiency
A deficiency in vitamin B3 can lead to a variety of symptoms, which can range from mild discomfort to severe illness.
1. Severe Deficiency
In severe cases, a deficiency in vitamin B3 leads to pellagra. This condition is marked by the “three Ds”: dermatitis, dementia, and diarrhea. If untreated, it can become fatal. Thankfully, severe deficiencies are rare in modern diets, still, you should be mindful of the symptoms.
2. Mild Deficiency Symptoms
Mild deficiencies of vitamin B3 often resemble those of other B vitamin deficiencies. Signs include feelings of fatigue, apathy, and confusion. You might have trouble remembering things or feel foggy during the day. Insomnia is another common sign, as your body struggles to maintain its normal rhythms in deficiency.
3. Skin and Mucous Membrane Symptoms
Niacin deficiency can manifest in the skin and mucous membranes. One of the telltale signs of vitamin B3 deficiency is a dark red rash, especially in areas exposed to sunlight. The skin may become dry, cracked, or scaly. You might also experience redness or a swollen appearance in your mouth and tongue.

1. Digestive Tract Problems
Niacin is crucial for a healthy digestive system. Symptoms may include inflammation, nausea, vomiting, or persistent diarrhea. These problems are linked to how the body properly absorbs and processes nutrients.
Taking proactive steps with balanced nutrition can help you mitigate these risks and prevent deficiencies. Products such as this energy gel from Supply6 are essential to give you a daily boost of energy. Supplement them with your workouts or meals and get a full dose of daily nutrition.
If left unchecked, these conditions can progress to severe stages, and impact both physical and mental health. You might be wondering if you’re at risk of a deficiency.
Who is at Risk for Vitamin B3 Deficiency?
Vitamin B3 deficiency is rare in developed countries but it still poses a significant health risk in certain parts of the world. It is noticeable in notable in parts of Africa, India, and China, which face food insecurity. This is often due to diets heavily based on corn.
This research data shows regions where niacin deficiency is prevalent and which groups are at more risk. Plus, it provides the recommended dietary allowance for all ages and the effect of high levels of niacin.
Certain populations are at an elevated risk. Refugees and displaced people often suffer higher rates as they have restricted access to a balanced diet. Plus, some medical conditions also enhance the risk. For example, Hartnup disease is a genetic disorder that impairs the body’s ability to convert tryptophan into niacin.
Another condition, carcinoid syndrome, causes tumors in the digestive system that divert tryptophan away from niacin production.
Maintaining a balanced intake of essential nutrients can help you avoid these risks. Nutritional products such as Supply6 360 offer a comprehensive blend of vitamins which can be particularly beneficial for busy people.
In such cases, diagnosing is important. If you suspect you might be deficient in vitamin B3, your doctor may conduct a thorough evaluation to pinpoint the cause.
Diagnosing Vitamin B3 Deficiency
Diagnosing this deficiency is a step-by-step process. It starts with examining what you eat every day. Doctors look for diets that are low in niacin-rich foods like poultry, red meat, eggs, and dairy.
Next, doctors observe symptoms. Early symptoms can be vague, like fatigue, indigestion, or mouth sores. As the deficiency progresses, issues like a bright red tongue, poor circulation, and even mental health problems like depression and confusion might develop. Without treatment, severe cases can lead to hallucinations, memory loss, and permanent nerve damage.
Laboratory tests are also crucial, mainly urine tests. These tests measure niacin by-products to determine how much vitamin B3 your body is processing. A low level of these by-products points to a deficiency, which can confirm the diagnosis.
When other tests are not conclusive or available, a doctor will try a therapeutic trial with niacin supplements. If the patient's symptoms improve, it confirms the diagnosis. A physical examination also helps. Doctors look for specific signs like a dark red rash on sun-exposed skin, an inflamed tongue, and characteristic skin lesions.
