EU SCIENTIFIC EVIDENCE PROFILE

Benfotiamine supplement compliance

A dossier-scoped EFSA opinion separates thiamin bioavailability from unresolved safety and labelling conversion. Formal market permission is a separate question.

INGREDIENT EVIDENCE · SCIENTIFIC OPINION · REFERENCE ONLY

One ingredient. Six independent evidence questions.

Benfotiamine — regulatory review required. Opinion published ; source reviewed . Original EN · EU · EFSA-Q-2024-00115 · Gall Pharma GmbH.

Chemically synthesised benfotiamine, proposed purity at least 98% w/w. Proposed intake: 300 mg/day — applicant proposal, not an approved dose. Adults; pregnancy and lactation excluded.

Separate scientific assessments and formal legal gaps — no aggregate PASS
Evidence areaStatusWhat it means
Novel Food authorisationNOT ESTABLISHEDThe scientific opinion is not a Commission authorisation; no current legal permission is established here. Not assessed here.
Safety assessmentNOT ESTABLISHEDSafety could not be established for the material and proposed conditions in this dossier.
Nutrient sourceASSESSEDAssessed as a thiamin source. This is not an Annex II permission to use it in supplements.
Thiamin bioavailabilityESTABLISHEDPositive scientific conclusion on thiamin availability; not efficacy or product safety.
Labelling conversionNOT ESTABLISHEDNo sufficiently supported conversion factor could be derived for labelling.
Country-specific requirementsREVIEW REQUIREDNo national market-access determination is made. Check the exact product and country separately. Not assessed here.

This dossier outcome is not a ban, a finding of harm at every dose, or approval of 300 mg/day. Positive bioavailability does not establish safety or market permission.

Recorded gaps: Material characterisation and particle/nanoparticle evidence; Reproducible manufacture and microbiological stability; Metabolic fate, bioaccumulation and adequate toxicology. These observations concern the submitted dossier, not every supplier material.

Prepare missing dossier information — nothing is sent
  1. Identify the exact supplier material, manufacturing method and specification version; do not match only by ingredient name.
  2. Map available identity, particle, stability and toxicology documents to the gaps in the opinion; document what remains missing.
  3. Obtain the separate legal basis for the exact Novel Food and nutrient source, and assess the intended country and population.
  4. Do not calculate label thiamin or an authorised dose from a proposed intake or an unestablished conversion factor.

This is a preparation checklist, not an upload, supplier request, safety validation or legal approval.

CLAIMS

What the profile supports

NO HEALTH CLAIM AUTHORISATION ESTABLISHED
  • Keep scientific nutrient-source assessment separate from lawful use of the material and any health-claim conditions.
  • Do not borrow a thiamin claim as evidence of benfotiamine authorisation.

Positive bioavailability is not an authorised health claim or a finished-product efficacy finding.

03

RESTRICTIONS

Conditions that can change the answer

  1. 01

    300 mg/day is the applicant-proposed intake for adults, excluding pregnancy and lactation; it is not an approved dose or safe upper limit.

  2. 02

    This dossier outcome is not a ban, a finding of harm at every dose, or approval of 300 mg/day. Positive bioavailability does not establish safety or market permission.

  3. 03

    No labelling conversion factor is established; missing data is not a zero conversion.

  4. 04

    Match the exact material and intended use to separate current Novel Food, nutrient-source and national legal evidence before a market decision.

POLISH NOTES

National regulatory layer

This page does not establish Polish market access, a national limit or notification acceptance. The original opinion is English-language EU scientific evidence, not a Polish legal decision.
