Market
Niacin (vitamin B3), supplied mainly as nicotinamide (niacinamide) or nicotinic acid, is an authorized nutrient source for dietary supplements in Brazil under ANVISA’s supplements framework. Products marketed as dietary supplements must comply with ANVISA composition rules, including minimum/maximum limits per population group and the use of authorized label claims. Imports of products subject to sanitary surveillance can require ANVISA administrative clearance via Siscomex import licensing, with the possibility of inspection prior to customs clearance. Regulatory treatment by NCM and “destaque” can change over time, so regulatory monitoring is a key operational requirement for niacin forms used in supplements.
Market RoleRegulated domestic consumer and supplement-manufacturing market (dietary supplements treated as a food category under ANVISA rules)
Domestic RoleUsed as a regulated nutrient source in domestically marketed dietary supplements (Vitamin B3/niacin) and as an input for supplement formulation and labeling-compliant products
SeasonalityNon-seasonal industrial ingredient; availability is driven by industrial production and import/logistics and not by agricultural harvest cycles.
Specification
Physical Attributes- Typically traded as a dry, free-flowing crystalline powder for blending into supplement premixes or finished dosage forms; moisture protection is important for handling stability.
Compositional Metrics- For dietary supplement use in Brazil, ingredient identity/purity/composition specifications must align with at least one accepted reference (e.g., Brazilian Pharmacopeia or other accepted pharmacopeias, Codex Alimentarius, JECFA, FCC, USP-DSC, EFSA) as provided in ANVISA supplement rules.
Grades- Dietary supplement ingredient grade aligned to recognized compendial specifications acceptable under ANVISA (reference-dependent).
Packaging- Commonly handled as bulk ingredient in lined fiber drums or multiwall bags; lot identification and COA alignment are typical for importer/manufacturer quality systems.
Supply Chain
Value Chain- Overseas vitamin manufacturer → Brazilian importer/distributor → local blending/premix or finished-supplement manufacturer → ANVISA-compliant labeling/claims → retail and pharmacy channels
Temperature- Ambient transport and storage; protect from heat extremes and humidity per supplier specification and stability program.
Shelf Life- Shelf-life is primarily sensitive to moisture ingress and packaging integrity; maintain sealed primary liner and lot/expiry traceability.

Risks
Regulatory Compliance HighMarket access for niacin in Brazil as a dietary supplement ingredient can be blocked if the finished supplement formulation/labeling is not aligned with ANVISA’s authorized sources (e.g., nicotinamide/niacinamide and nicotinic acid), population-group limits (including maximum limits in the daily recommended consumption), and authorized claims; imports may also be delayed or stopped if ANVISA import licensing/inspection requirements are not met.Run an ANVISA compliance check for the exact niacin form and intended population group(s): verify the constituent/source is authorized, confirm daily recommended amount does not exceed the ANVISA maximum for that group, use only authorized claims, and maintain a ready-to-audit dossier (specifications/COAs and labeling rationale) for import clearance and inspections.
Regulatory Change MediumBrazil’s supplement constituent lists, limits, and administrative import treatment can be updated via ANVISA and Siscomex publications; operational requirements may change by NCM subitem and “destaque” (e.g., Feb 2026 changes for nicotinic acid and sodium nicotinate).Monitor ANVISA communications and Siscomex import notices for NCM and supplement list updates; refresh internal regulatory matrices and importer instructions when new ‘tratamento administrativo’ or amended supplement lists are published.
Documentation Gap MediumIf the niacin ingredient specification and COA do not clearly map to an accepted identity/purity reference (as required under ANVISA supplement rules), companies may face compliance findings during audits/inspections or import clearance delays.Require suppliers to provide compendial alignment (e.g., pharmacopeial/Codex/JECFA/FCC/USP-DSC references as applicable) and keep translated/specification dossiers accessible to the Brazilian importer and manufacturer QA teams.
Labor & Social- High enforcement sensitivity in Brazil’s supplement market for products misclassified as supplements, use of unauthorized ingredients, and use of unauthorized/therapeutic claims in marketing; enforcement actions can include suspension of sale and advertising.
FAQ
Which forms of niacin are authorized as nutrient sources for dietary supplements in Brazil?ANVISA’s dietary supplement constituent list includes niacin sources such as nicotinamide/niacinamide (CAS 98-92-0) and nicotinic acid (CAS 59-67-6) for use in dietary supplements, subject to the applicable rules for limits and labeling.
What is the maximum daily amount of niacin allowed in dietary supplements for adults in Brazil?ANVISA’s maximum limit table for dietary supplements lists a niacin maximum of 35 mg in the daily recommended consumption for the population group “≥ 19 years,” with different maxima for other population groups.
What kinds of label claims are permitted for niacin on dietary supplements in Brazil?ANVISA’s authorized claims list includes functional statements for niacin such as supporting maintenance of skin and mucous membranes and supporting energy metabolism and macronutrient (protein, carbohydrate, and fat) metabolism, provided the supplement meets the related composition requirements.
Do imports of niacin-related products face ANVISA control in Siscomex?For products subject to ANVISA sanitary surveillance, ANVISA describes import licensing through Siscomex (LI) and notes that LI deferment can lead to inspection prior to customs clearance (with references to RDC 81/2008). Siscomex notices can also change the administrative treatment applied to specific NCM items that fall under ANVISA anuência.
