Niacin (Vitamin B3) The Ultimate Guide for B2B Buyers & Industry Professionals 

  1. English Name: Niacin (it’s also called Vitamin B3 or nicotinic acid—pronounced “NY-uh-sin”! It’s one of the 8 B-vitamins, and your body needs it to turn food into energy. Fun fact: “Niacin” comes from “nicotinic acid vitamin”—but don’t confuse it with nicotine (they’re totally different!).)
  2. Specification
    • Purity: ≥ 99.5% (HPLC tested—pharmaceutical/food-grade, no impurities; meets global standards like USP and EP)
    • Solubility: Highly water-soluble (dissolves fast in water, juices, or smoothies—no grit, even in cold liquids)
    • Moisture: ≤ 0.5% (keeps the crystals dry, so they don’t clump or lose potency; stable for 3+ years sealed)
    • Heavy Metals: ≤ 1 ppm (ultra-safe for oral consumption—strictly regulated for vitamin use)
    • Form: White to off-white crystalline powder or small tablets (looks like fine sugar, but with a mild, slightly acidic taste)
  3. Appearance: White crystalline powder with a very faint, almost odorless scent—definitely not a yellowish-white solid with chocolate aroma! It’s practically scentless, and any “taste” is subtle (slightly tart, not sweet or chocolatey).
  4. CAS NO.: 59-67-6 (this is the exact CAS for niacin (nicotinic acid)—since it’s a single B-vitamin, there’s no confusion here!)
  5. Lead time: 3–7 Working Days (we stock food-grade niacin powder and tablet forms—fast for supplement brands, fortified food makers, and wellness companies)
  6. Package:
    • Small sizes: 100g/500g resealable plastic bags (easy for small-batch use) or 100-count tablets (blister packs for home use)
    • Bulk: 25kg food-grade drums (lined with plastic—27 drums per tray; includes desiccants to prevent moisture and clumping)
  7. Main Market: Global—North America (multivitamins, energy drinks), Europe (fortified cereals, skincare), Asia (dietary supplements, functional foods). Popular with people needing B-vitamin support (like busy professionals, athletes, or those on restricted diets).
  8. Applications & Main Benefits
    • Dietary Supplements
      • Multivitamins: Added as a key B-vitamin (supports energy production—fights tiredness from B3 deficiency)
      • Niacin Tablets: 25–100mg per serving (used for heart health support—helps maintain healthy cholesterol levels; note: high doses may cause skin flushing)
      • B-Complex Blends: Paired with other B-vitamins (B1, B2, B6)—boosts overall energy and nervous system health
    • Fortified Foods & Beverages
      • Breakfast Cereals: Sprayed onto cereals (adds essential nutrients—great for people who skip nutrient-rich meals)
      • Energy Drinks: Mixed into low-sugar energizers (supports quick energy without crashing—works with caffeine)
      • Plant-Based Milks: Added to soy, oat, or almond milk (matches the B3 content of dairy milk—ideal for vegans)
    • Skincare
      • Facial Serums: 2%–5% niacinamide (a form of niacin) in anti-aging products (reduces redness, fades dark spots, and strengthens skin barrier—great for sensitive skin)
      • Moisturizers: Added to daily lotions (hydrates and soothes—helps with acne or dryness)
    • Medical Use
      • Prescription Doses: High-dose niacin (500mg+) for managing cholesterol (under doctor supervision—monitors for side effects like flushing)

Why Niacin Is Essential

  • Energy Booster: Turns carbs, fats, and proteins into energy—no B3, and your body can’t use food efficiently (hello, midday slumps!).
  • Heart Health Support: Helps keep cholesterol levels in check (when used as directed—always with a doctor’s okay for high doses).
  • Skin & Nervous System: Supports healthy skin (via niacinamide) and keeps nerves working well—no more tingling hands or dry, irritated skin.
  • Vegan-Friendly: Easy to add to plant-based diets (which sometimes lack B3)—keeps vegans/vegetarians nutrient-balanced.

Quick Tips & Notes

  • Niacin vs. Niacinamide: Niacinamide (a form of B3) doesn’t cause skin flushing—use it for skincare or if you’re sensitive to niacin’s flushing effect.
  • Flushing Tip: If you get niacin flushing (warm, red skin), take it with food or switch to niacinamide—it’s harmless but can be uncomfortable.
  • Storage: Keep in a cool, dry place—moisture makes crystals clump, but breaking them apart won’t ruin the vitamin.
  • Don’t Overdose: Stick to recommended doses (25–100mg daily for most people)—high doses can damage the liver (always check labels or ask a doctor).

Niacin: The Ultimate Guide for B2B Buyers & Industry Professionals

Looking for a reliable, high-quality Niacin supplier for your cosmetic, pharmaceutical, or dietary supplement formulations? You’ve landed in the right place. This definitive guide cuts through the noise, offering B2B clients and industry partners a detailed look at Niacin—from its fundamental properties and health benefits to sourcing from a trusted manufacturer and exporter. Let’s dive in.

1. What is Niacin?

Niacin, also known as Vitamin B3, is an essential water-soluble vitamin crucial for human health. It exists in two main forms: nicotinic acid and nicotinamide. For industrial and pharmaceutical applications, understanding its purity and specific form is critical for efficacy in your final products.

2. Source, Chemical Properties & Specifications

  • Product Source: While naturally present in many foods, the Niacin used in bulk commercial applications is typically produced synthetically to ensure highest purity, consistency, and scalability. It can also be derived from natural sources for specific market demands.

  • Chemical Identity:

    • CAS Number: 59-67-6 (Nicotinic Acid); 98-92-0 (Nicotinamide)

    • Molecular Formula (MF): C6H5NO2 (Nicotinic Acid); C6H6N2O (Nicotinamide)

    • Molecular Weight (MW): 123.11 g/mol (Nicotinic Acid); 122.12 g/mol (Nicotinamide)

    • EINECS: 200-441-0 (Nicotinic Acid); 202-713-4 (Nicotinamide)

3. What is the Best Niacin? A B2B Buyer’s Checklist

Choosing the “best” Niacin isn’t one-size-fits-all; it depends on your application. Here’s what to look for in a bulk Niacin supplier:

  • Ingredients & Purity: Seek >99.5% purity, verified by HPLC. The best suppliers offer ultra-pure, low-residual Niacin.

  • Efficacy & Compliance: Must comply with USP, Ph. Eur., and FCC standards for global markets. Look for GMP certified plant extract facilities.

  • Origin & Manufacturer: Partner with a GMP certified plant extract for cosmetics and pharmaceuticals. Origin matters for quality control and supply chain transparency.

  • Application & Usage: Used in tablet pressing, capsule filling, powder blends, and liquid formulations. Dosage varies:

    • Dietary Supplements: Typically 15-500 mg per serving.

    • Food Fortification: Lower doses as per regional regulations.

    • Cosmetics: 0.5-5% in topical formulations.

  • Applicable Industries: Ideal for dietary supplement raw material manufacturer, cosmetic raw material supplier bulk, pharmaceutical (API), and food-grade botanical extract supplier.

  • Health Benefits & Daily Intake:

    • Key Benefits: Supports cardiovascular health, aids energy production, maintains healthy skin, and supports cognitive function.

    • Daily Intake: RDA is 14-16 mg for adults. Therapeutic doses are higher and should be guided by a healthcare professional.

  • Side Effects & Precautions: High doses of nicotinic acid can cause “niacin flush” (a temporary skin redness and itching). Nicotinamide generally does not cause this. A reputable supplier provides clear usage guidelines.
