Niacin (Vitamin B3)

Niacin, also known as Vitamin B3, is an essential nutrient commonly used as a food additive to fortify and enrich food products. It plays a crucial role in energy metabolism and maintaining healthy skin, nerves, and digestion. Niacin occurs in two main forms used in food: nicotinic acid and niacinamide (nicotinamide).

• Appearance: White crystalline powder.

• Taste: Slightly bitter.

• Solubility: Soluble in water (niacinamide is more soluble than nicotinic acid).

• Stability: Stable to heat, light, and oxidation, making it suitable for processing and storage.

1. Nutrient Fortification:

o Fortified Foods: Niacin is added to cereals, bread, flour, and other grain-based products as part of enrichment programs to prevent deficiencies.

o Functional Foods and Drinks: Used in energy drinks, protein bars, and dietary supplements for its role in energy production and health.

2. Dietary Supplement:

o Niacinamide: Commonly included in multivitamins and supplements to prevent or treat Vitamin B3 deficiency.

o Prevents conditions like pellagra, which results from niacin deficiency.

3. Meat Curing and Processing:

o Added to processed meats to enhance nutritional value.

4. Infant Nutrition:

o Added to baby formulas and fortified baby foods to meet dietary requirements.

• Energy Production: Helps convert carbohydrates, fats, and proteins into energy.

• Skin and Nerve Health: Essential for maintaining healthy skin and proper nervous system function.

• Cholesterol Regulation: Niacin (at high therapeutic doses) is used to manage cholesterol levels by   increasing HDL ("good" cholesterol) and reducing LDL and triglycerides.

• Cost-Effective: Affordable and widely available.

• Thermally Stable: Can withstand cooking, baking, and other food processing methods without significant   loss.

• Versatile: Suitable for a variety of foods, from baked goods to beverages.

• Daily Requirements: The recommended daily intake (RDI) for adults is 14-16 mg per day.

• Overdose Risks: Excessive intake (over 35 mg/day) may cause side effects like flushing, itching, or   gastrointestinal discomfort, especially with nicotinic acid.

• Regulatory Approval: Approved by major health and regulatory organizations (FDA, EFSA, WHO).

• Breakfast cereals.

• Bread and flour (especially in enriched products).

• Pasta and rice.

• Milk and dairy products.

• Nutritional drinks and supplements.

• Flushing Effect: Nicotinic acid can cause skin flushing and warmth at higher doses, though niacinamide   does not have this effect.

• Taste Impact: In large quantities, it may impart a slightly bitter taste to foods.

• Derived synthetically or from fermentation processes, which are generally low-impact and sustainable.

Niacin is part of many government-mandated food enrichment programs aimed at reducing nutrient deficiencies, particularly in regions where polished grains are a dietary staple.
