Vitamin B3 (Niacinamide) Overview
Niacinamide, also known as nicotinamide, is the amide form of vitamin B3, identified by CAS number 98-92-0, molecular formula C6H6N2O and molecular weight 122.12 g/mol. It is the flush-free form of vitamin B3, and it is the form most widely used in dietary supplements because it supports NAD+ (nicotinamide adenine dinucleotide) synthesis without the skin-flushing reaction associated with nicotinic acid. Both forms are recognized as vitamin B3 by the USP-NF and European Pharmacopoeia, and both are authorized as a vitamin for food supplements in the European Union.
For the dietary supplement industry, niacinamide is a core nutrient in energy, cellular-health, NAD+ support, skin health, B-complex and healthy-aging products. Purecium supplies niacinamide as a white, free-flowing crystalline powder standardized to 99.5% minimum assay, sold exclusively as a B2B raw material for distributors, contract manufacturers, private-label producers and finished supplement brands.
Source & Ingredient Identity
Purecium Niacinamide is manufactured by a synthetic route: 3-methylpyridine (beta-picoline) is oxidized to nicotinic acid, which is then converted to the amide through ammoniation to yield nicotinamide, followed by purification and crystallization. The synthetic route produces a stable, high-purity white powder with defined crystalline structure, free from the impurities and batch variability that complicate fermentation-derived actives, and it is fully vegan with no animal-derived input.
One specification is offered under this product line: Niacinamide USP grade, minimum 99.5% assay on a dried basis, conforming to USP and FCC monographs, produced in China and non-irradiated, with no allergens, no gluten and no GMO material. For B2B buyers, the critical purchasing checks are the assay and related-substance profile on the Certificate of Analysis, the crystalline form (which affects flow and compression), and the declared impurity profile, since residual 3-methylpyridine and nicotinic acid are controlled in pharmacopeial monographs.
Key Characteristics of Vitamin B3 (Niacinamide)
1. Flush-free by design. Unlike nicotinic acid, niacinamide does not trigger the prostaglandin-mediated skin flush, making it the preferred form for high-dose B3 products, B-complex blends and beauty-from-within formulas where consumer comfort matters.
2. Direct NAD+ precursor. Niacinamide feeds the NAD+ salvage pathway, supporting cellular energy production and DNA-repair enzyme activity; it is the same molecule used in the majority of commercial NAD+ support supplements because it is orally bioavailable and well tolerated at nutritionally relevant doses.
3. Stable and formulation-flexible. The white crystalline powder is stable under normal storage, flows well for direct compression and blends uniformly with other B vitamins, minerals and botanical extracts. Niacinamide contributes to normal energy-yielding metabolism and normal functioning of the nervous system, claims recognized by EFSA for vitamin B3.
Vitamin B3 (Niacinamide) Manufacturing
The manufacturing process begins with the catalytic oxidation of 3-methylpyridine to nicotinic acid, followed by amidation with ammonia to form nicotinamide. The crude product is purified by decolorization, crystallization and drying to yield the white crystalline powder, and the finished lot is assayed by HPLC against the USP-NF and European Pharmacopoeia monographs for nicotinamide. Related substances, including residual nicotinic acid and 3-methylpyridine, are controlled within monograph limits at every production scale.
Every production stage is process-controlled, and each finished lot is verified by HPLC before release. Heavy metals, residual solvents, moisture and microbiological results are reported on the batch Certificate of Analysis, and each lot is traceable from starting material to finished drum. The crystalline powder is packed with moisture-barrier liners to preserve flow and assay during storage and transport.
Applications of Vitamin B3 (Niacinamide)
Cellular energy and NAD+ support are the primary applications of niacinamide. Mechanistically, nicotinamide is a building block for NAD+, the central coenzyme of cellular energy metabolism and the substrate for sirtuin and poly(ADP-ribose) polymerase enzymes involved in DNA repair and cellular resilience. By replenishing the NAD+ pool through the salvage pathway, niacinamide supports mitochondrial energy production and cellular maintenance, a role recognized by EFSA in its authorized claim that vitamin B3 contributes to normal energy-yielding metabolism.
Skin health is the second major application area: niacinamide is a well-established cosmeceutical and beauty-from-within ingredient studied for skin barrier support, sebum regulation and even-tone appearance, and it is frequently co-formulated with collagen, hyaluronic acid and vitamin C in skin-support systems. Peer-reviewed research has examined niacinamide in NAD+ biology, skin function and metabolic contexts extensively; finished-product claims should always follow the regulations of the destination market.
Niacinamide is compatible with tablets, hard capsules, softgels, gummies, sachets and powder blends. It is a standard component of B-complex, multivitamin and NAD+ support products, and pairs naturally with vitamin B6, magnesium, resveratrol and other NAD+ modulators. The free-flowing crystalline powder gives B2B buyers full flexibility across dry and chewable dosage forms.
Manufacturing & Quality Control
Purecium Niacinamide is produced in facilities operating under ISO 9001 and FSSC 22000 certified quality systems, with Kosher and Halal certification available. Analytical methods follow the current USP-NF and European Pharmacopoeia monographs for Niacinamide, and each batch is assayed by HPLC for content.

Vitamin B3 (Niacinamide) Frequently Asked Questions (FAQ) for B2B Buyers
Q1. What is niacinamide used for in dietary supplements?
Niacinamide (nicotinamide, vitamin B3) is used primarily for NAD+ support, cellular energy metabolism, nervous system function and skin health. As the amide form of vitamin B3, it feeds the NAD+ salvage pathway that maintains cellular energy production and DNA-repair activity, and it does so without the flush reaction of nicotinic acid, which is why it dominates high-dose B3 products. EFSA recognizes that vitamin B3 contributes to normal energy-yielding metabolism and normal functioning of the nervous system. Purecium supplies niacinamide as a 99.5% minimum USP-grade powder for distributors, contract manufacturers, private-label producers and supplement brands.
Q2. What is the difference between niacinamide and niacin (nicotinic acid)?
Niacinamide and niacin are both vitamin B3, but they differ chemically by one functional group: niacin (nicotinic acid, CAS 59-67-6) carries a carboxyl group while niacinamide (nicotinamide, CAS 98-92-0) carries an amide group. The practical difference is the flush: niacin triggers a prostaglandin-mediated skin flushing and itching reaction at doses above roughly 30 to 50 mg, while niacinamide does not, which is why it is called the flush-free form. Both support NAD+ synthesis, though through partly different routes. Niacinamide is preferred for high-dose B3, B-complex and beauty-from-within products, while niacin is used where cholesterol-management positioning is intended and the flush is either accepted or managed with sustained-release technology. Labeling must state the exact form used.
Q3. How does niacinamide support NAD+ levels?
Niacinamide is converted to NAD+ through the salvage pathway, the most efficient route of NAD+ biosynthesis in human cells. The pathway involves the sequential action of nicotinamide phosphoribosyltransferase (NAMPT) and nicotinamide mononucleotide adenylyltransferase (NMNAT), which convert nicotinamide to nicotinamide mononucleotide (NMN) and then to NAD+. This is the same pathway used by the body to recycle NAD+ from cellular metabolism, and oral niacinamide is well absorbed and bioavailable for this purpose. Because NAD+ declines with age and is consumed by DNA-repair enzymes, niacinamide supplementation is used in healthy-aging and cellular-energy products. Peer-reviewed research supports this mechanism; finished-product claims must follow destination-market regulations.
Q4. Is niacinamide the same as nicotinamide?
Yes, they are the same molecule. Niacinamide and nicotinamide are interchangeable names for the amide form of vitamin B3, CAS 98-92-0, molecular formula C6H6N2O. 'Niacinamide' is the INCI (cosmetic) and common supplement name, while 'nicotinamide' is the pharmacopeial and scientific name used in the USP-NF and European Pharmacopoeia. Both names appear on ingredient labels depending on the market and the product category, and both refer to the identical compound. When sourcing, confirm the CAS number rather than relying on the name, and note that it is distinct from nicotinic acid (niacin) and from nicotinamide riboside (NR), which is a different NAD+ precursor.
Q5. What assay and quality specifications should I expect for niacinamide?
A USP-grade niacinamide powder should be assayed at 99.0% to 101.0% (Purecium standardizes to 99.5% minimum) by HPLC against the USP-NF or EP nicotinamide monograph, with related substances controlled — typically residual nicotinic acid not more than 0.1% and 3-methylpyridine within monograph limits — melting point in the range of 128 to 131 degrees Celsius, moisture not more than 0.5%, heavy metals within monograph limits, conforming residual solvents and microbial counts within USP/EP limits. The particle-size profile should be documented for blending and compression performance. Purecium reports all of these on the batch Certificate of Analysis, including the assay method, production date and expiry date.
Q6. What grades of niacinamide are available, and which should I choose?
Niacinamide is available in food, feed and pharmaceutical grades; for dietary supplements the relevant standards are USP-NF, EP and FCC. Purecium supplies USP/FCC-grade niacinamide at 99.5% minimum assay for supplement manufacturing, suitable for tablets, capsules, gummies and powder blends. Pharmaceutical-grade material meeting EP monographs is available for markets requiring the European standard, and the same production line supports both. Buyers should specify the monograph their destination market requires, since assay, impurity limits and documentation requirements differ slightly between USP and EP. Purecium provides the matching specification sheet and CoA for either standard.
Q7. Is niacinamide suitable for skin-health and beauty-from-within products?
Yes, niacinamide is one of the most widely studied ingredients in both topical skincare and beauty-from-within supplements. Orally, vitamin B3 contributes to the maintenance of normal skin, a claim recognized by EFSA, and niacinamide is frequently co-formulated with collagen, hyaluronic acid, vitamin C and biotin in skin-support systems. Mechanistically, its NAD+-related cellular functions support skin barrier maintenance and resilience. It is compatible with tablets, capsules, gummies and powder sachets, and the flush-free profile makes it consumer-friendly at the higher doses sometimes used in beauty formulas. Formulators should verify claim wording per market, since cosmetic versus food-supplement regulations differ.
Q8. How does niacinamide differ from nicotinamide riboside (NR) and NMN?
Niacinamide, nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are three different NAD+ precursors. Niacinamide (CAS 98-92-0, MW 122.12) is the simple amide form of vitamin B3 and the most established, cost-effective precursor; NR (CAS 1341-23-7) is a ribosylated form that enters cells via specific transporters; NMN (CAS 1094-61-7) is the mononucleotide intermediate that sits one step upstream of NAD+. All three feed NAD+ synthesis, but niacinamide is the only one that is a recognized essential vitamin with pharmacopeial monographs and authorized claims. For mainstream products, niacinamide delivers NAD+ support at a fraction of the cost of NR or NMN; premium NAD+ lines often combine forms. Purecium supplies niacinamide as the stable, regulatory-clear foundation for NAD+ products.
Q9. Can niacinamide be used in high-dose products without side effects?
Niacinamide is well tolerated, and unlike niacin it does not cause flushing at equivalent doses. The FDA and EFSA have established tolerable upper intake levels for vitamin B3 that apply to both forms — commonly 35 mg per day in the United States for niacinamide and niacin combined, with higher levels allowed in the European Union under specific conditions. Some clinical protocols have used substantially higher niacinamide doses under professional supervision. For commercial supplements, formulators should design doses within the applicable upper levels of their destination market, and high-dose products should be reviewed with the brand's regulatory advisors. Purecium provides regulatory-support documentation to assist with dosage positioning.
Q10. What quality documentation should I request when sourcing niacinamide?
A professional supplier should provide a current specification sheet, a batch-specific Certificate of Analysis showing identification, HPLC assay, related substances, melting point, moisture, heavy metals, residual solvents and microbial results, an SDS, allergen and gluten statements, and non-GMO declarations. Depending on your destination market, also request Kosher and Halal certificates, copies of the ISO 9001 and FSSC 22000 certificates, and stability data for registration purposes. Because niacinamide is a synthetic powder, also confirm the route (synthetic versus fermentation) if your brand positioning requires it. Purecium provides this full documentation set on request for every shipment.
Q11. Is niacinamide vegan, gluten-free, allergen-free and non-GMO?
Yes. Niacinamide produced by the synthetic route uses no animal-derived input and no fermentation organisms, so it is fully suitable for vegan labeling and is inherently non-GMO. It contains no gluten-containing ingredients and no major allergens, and the manufacturing facility follows allergen-control procedures. Allergen-free, gluten-free, non-GMO and vegan statements are provided with each shipment. Buyers should request these statements per lot because they must be documented for finished-product labeling in most regulated markets. Synthetic niacinamide also avoids the allergen questions that can accompany fermentation-derived ingredients grown on soy or wheat-based media.
Q12. What is the MOQ and lead time for niacinamide from Purecium?
The minimum order quantity is 25 kg. The powder is packed in 25 kg drums with food-grade aluminum-foil inner bags, and samples and technical documentation are available before you commit. Standard production lead time is typically 7 to 15 working days after order confirmation, depending on the specification and production schedule, with faster dispatch for stocked items. For North American customers, Purecium holds inventory at its US warehouse, enabling pickup or delivery within approximately two days. Export documentation, including the Certificate of Analysis, packing list and certificate of origin, is prepared for every shipment.
Q13. How should niacinamide be stored, and what is the shelf life?
Store niacinamide in tightly sealed original containers in a cool, dry place below 25 degrees Celsius, protected from moisture and strong light. The white crystalline powder is stable under these conditions, and shelf life is generally 36 months from the date of manufacture. Avoid excessive humidity during blending, since the crystalline form can cake if exposed to moisture, and reseal containers immediately after use. Finished-product stability depends on the complete formulation and packaging system, so stability studies should be run on the actual product. Each shipment's CoA states the production date and expiry date for inventory planning.
Q14. Can niacinamide be combined with magnesium, B6 and resveratrol in NAD+ formulas?
Yes, this is a common and well-supported combination in NAD+ and cellular-energy products. Magnesium is a cofactor for many enzymes in energy metabolism and is frequently co-formulated with B vitamins; vitamin B6 supports amino acid and neurotransmitter metabolism and complements the B-complex profile; resveratrol is studied alongside NAD+ modulation for cellular-health positioning. All are dry powders that blend well in tablets, capsules and sachets. Formulators should verify ingredient compatibility, particle-size matching and blend stability, and confirm label claims comply with destination-market regulations. Purecium can supply technical guidance for these combinations.
Q15. Why should we source niacinamide from Purecium?
Purecium supplies Niacinamide (Vitamin B3) as a B2B raw material for distributors, contract manufacturers, private-label producers and supplement brands, standardized to 99.5% minimum assay and produced to USP and FCC standards via a controlled synthetic route.
