The Vitamins: Vitamin B3 Niacin

The Kaufmann Diet is all about using nutrition as a powerful tool to support good health, prevent disease, and sometimes even reverse diseases. In this series, we break down the components of nutrition into their specific parts, and discuss how they can support––and sometimes hinder––our health. The second part of this series covers vitamins, what they are, how they fit into your Kaufmann Diet, and the best sources of these nutrients. 

Vitamin B3 (Niacin)

Vitamin B3, also known as niacin, is an essential nutrient that plays an important role in the metabolism of both fats and carbohydrates in the body, converting them into energy. It’s also important for maintaining healthy skin, nerves, and digestive system function.

The primary forms of niacin used in the body are nicotinic acid and niacinamide (also known as nicotinamide). These two forms have similar functions in terms of general metabolism but differ in their specific uses and effects:

1. Nicotinic Acid: This form of niacin is primarily used for its ability to manage cholesterol levels. It can help reduce LDL cholesterol and triglycerides and raise HDL cholesterol. However, nicotinic acid can cause “flushing,” a common side effect characterized by redness, warmth, itching, or tingling of the skin. This effect can be minimized with certain formulations or by taking aspirin before the niacin.

2. Niacinamide: Unlike nicotinic acid, niacinamide does not affect cholesterol levels but is used for its benefits in skin care, arthritis, and other health conditions. It is also important in preventing niacin deficiency and is used in the treatment of pellagra. Niacinamide is generally preferred for these purposes because it does not cause the flushing associated with nicotinic acid.

Both forms are important in cellular metabolism, where they are part of coenzymes NAD (nicotinamide adenine dinucleotide) and NADP (nicotinamide adenine dinucleotide phosphate). These coenzymes are involved in many oxidation-reduction reactions crucial for energy production and other metabolic processes.

Niacin offers a range of health benefits due to its involvement in metabolic processes and its role as a precursor to coenzymes that are essential for cell function. Here are several key health benefits associated with niacin:

1. Cholesterol Management: Niacin is well known for its ability to help regulate lipid profiles. It can significantly decrease LDL (bad) cholesterol and triglycerides, while increasing HDL (good) cholesterol.

2. Cardiovascular Health: Beyond its effects on cholesterol, niacin helps improve the health of arteries and reduce atherosclerosis (hardening of the arteries).

3. Skin Health: Niacin helps protect skin cells from sun damage, and is beneficial for treating various skin conditions. Niacinamide, a form of niacin, is commonly used in topical treatments to alleviate acne, rosacea, and other inflammatory skin conditions.

4. Mental Health: There is evidence suggesting that niacin can support brain function and may protect against Alzheimer’s disease and other age-related cognitive decline. It may also play a role in treating depression and anxiety.

5. Joint Mobility and Arthritis: Niacinamide has been shown to improve joint flexibility and reduce symptoms of arthritis, such as pain and swelling.

6. Diabetes: Niacinamide is thought to help preserve beta cell function in the pancreas, which can be beneficial in managing type 1 diabetes.

7. Digestive Health: As part of its role in metabolizing food, niacin helps maintain healthy digestion and can assist in converting food to energy.

Niacin, or vitamin B3, is found in a variety of foods, making it relatively easy to get enough of it in your diet. Here are some excellent dietary sources of niacin that are Kaufmann Two Diet approved:

1. Meats: Chicken breast, turkey, beef, and liver are particularly high in niacin.

2. Fish: Tuna, salmon, and mackerel are rich sources of niacin.

3. Avocado

4. Seeds and Nuts: Sunflower seeds, almonds, and chia seeds.

5. Green Vegetables

6. Legumes: Peas, lentils, and beans are good plant-based sources of niacin––these are relegated to Kaufmann Two 

The recommended daily allowances for niacin vary. Children should get between 2-8 mg/day, increasing with age. Men should get 16 mg/day, while women require 14 mg/day. These values represent niacin equivalents, acknowledging that the body can also convert the amino acid tryptophan to niacin. Approximately 60 mg of tryptophan can be converted into 1 mg of niacin.

Anti-fungal Properties of Niacin

Niacin, or vitamin B3, is not typically recognized for direct anti-fungal properties in the way that specific anti-fungal medications are. However, there are some aspects of niacin that relate indirectly to fungal infections, particularly in the context of the immune system’s function.

Niacin plays a role in maintaining the integrity of the skin and mucous membranes, which can help prevent fungal infections by acting as a barrier. More importantly, niacin is crucial for the proper function of immune cells. Adequate levels of niacin can support the immune system’s ability to combat pathogens, including fungi.

Some studies have investigated the role of niacin or its derivatives in enhancing the immune response or modifying inflammatory responses, which could indirectly affect how the body deals with fungal infections. Niacinamide, a form of vitamin B3, has been researched for its potential effects on various skin conditions, but its role in treating fungal infections specifically is not well established.

Nicotinamide has been found to be effective at inhibiting Candida albicans in some studies, and might ultimately prove to be useful against resistant strains of the yeast, but more research is needed. Until then, getting enough B3 in your diet is a good way to help support overall health and protect against pathogenic fungi.
