Dietary supplements bridge food and medicine, providing vitamins, minerals, botanicals, amino acids to support health without treating disease. Registration of dietary supplements according to the requirements of the EAEU follows risk-based assessment distinguishing established ingredients with recognized safety from novel substances requiring toxicological evaluation. Vitamins and minerals at physiological doses (50-150% RDA) require only compliance with maximum permitted levels in Appendix 5 of EAEU Technical Regulation 021/2011, no additional safety testing. Botanical ingredients with traditional food use >30 years in EAEU region rely on historical safety data from monographs, ethnobotanical literature, absence of adverse event reports. Novel ingredients—exotic botanicals, synthesized compounds, concentrated extracts not traditionally consumed—require acute toxicity (LD50), 90-day subchronic toxicity study in rodents, genotoxicity battery (Ames, micronucleus, chromosomal aberration), allergenicity assessment. Safety package for novel ingredient costs $80,000-$150,000 and takes 9-15 months.

Regulatory Boundaries Between Supplements and Medicines

Critical distinction separating dietary supplements from medicinal products involves claims, dosage, ingredient potency, and intended use. Supplements support normal physiological functions, medicines treat or prevent disease. Regulatory classification determines approval pathway: notification for supplements (2-4 months), full registration for medicines (12-24 months, clinical trials required).

Classification criteria and regulatory implications:

  • Structure-function claims versus disease claims. Supplements can state «supports immune health» or «promotes cardiovascular function» (physiological support), but cannot claim «treats hypertension» or «prevents cancer» (disease treatment) — crossing line triggers medicinal classification and registration requirements.
  • Ingredient dose limits define classification. Vitamin C at 100-500 mg is dietary supplement, at 1000+ mg approaches therapeutic dose requiring medicinal justification; curcumin 500 mg/day is supplement, 2000+ mg/day for anti-inflammatory action is medicine.
  • Pharmaceutical dosage forms trigger medicinal status. Tablets and capsules acceptable for supplements, but injectable forms, rectal/vaginal suppositories, transdermal patches are pharmaceutical delivery systems indicating medicinal intent regardless of ingredient.
  • Combination products with medicinal ingredients. Adding pharmaceutical API (metformin, sildenafil) to botanical supplement makes entire product a medicine requiring prescription drug registration — manufacturers attempting this face criminal liability for illegal drug marketing.
  • Health claims require substantiation dossier. Even permitted structure-function claims need scientific support: systematic literature review, mechanism of action, human studies showing benefit, claim-substantiation review costs $15,000-$30,000 for comprehensive dossier.

Interesting fact: Regulatory authorities conduct post-market testing finding 10-15% of supplements contain undeclared pharmaceutical ingredients (sildenafil in male enhancement, sibutramine in weight loss) — adulterated products face immediate suspension, criminal prosecution, manufacturer blacklisting.

Quality Standards and Manufacturing Requirements

Unlike pharmaceuticals with precise API specifications and strict process controls, supplements use agricultural raw materials with natural variability in active constituent content. EAEU regulations require standardization to marker compounds, identity testing, contamination limits (heavy metals, pesticides, microorganisms) ensuring consistent quality and safety.

Good Manufacturing Practices (GMP) for dietary supplements:

  • Raw material qualification and supplier audits. Botanical identity verification by macroscopic, microscopic, chromatographic methods per pharmacopoeia monographs, suppliers provide certificates of analysis (CoA) for each batch, random audit testing detects mislabeling or adulteration.
  • Standardization to marker compounds. Plant extracts standardized to active constituents: ginkgo to flavonoids 24% + terpene lactones 6%, milk thistle to silymarin 70-80%, ensures consistent efficacy batch-to-batch despite agricultural variability.
  • Contamination limits per TR CU 021/2011. Heavy metals (lead <6 mg/kg, cadmium <1 mg/kg, mercury <0.1 mg/kg, arsenic <3 mg/kg), pesticide residues
  • Stability testing for shelf-life determination. Real-time stability study at 25°C/60% RH for claimed shelf life (24-36 months typical), accelerated study at 40°C/75% RH for 6 months, active ingredient content must remain 90-110% of label claim throughout validity.
  • Label accuracy verification. Finished product testing must match label declarations ±20% for botanical content, ±10% for vitamins/minerals, discrepancies constitute misbranding with penalties including product seizure and sales prohibition.

Manufacturing audit statistics show 25-35% of supplement facilities have GMP deficiencies (inadequate cleaning validation, insufficient identity testing, poor documentation) requiring corrective actions before registration approval — pre-approval facility inspection critical.

Ingredient Safety Assessment: Why Novel Botanicals Require Toxicological Studies While Traditional Herbs Use Historical Use Data

Clinical Substantiation for Bioactive Ingredients

While supplements don’t require clinical trials for registration like medicines, bioactive ingredients making functional claims should have human study evidence demonstrating benefits. Regulatory scrutiny increases for high-dose extracts, novel botanicals, or claims bordering on therapeutic effects.

Evidence levels supporting dietary supplement claims:

  • Systematic literature reviews and meta-analyses. Comprehensive search of PubMed/Embase databases, inclusion of randomized controlled trials (RCTs), quality assessment per Cochrane methods, pooled effect sizes demonstrating statistical significance — strongest evidence short of new trials.
  • Randomized controlled trials in target population. Double-blind placebo-controlled design, 50-200 subjects, primary outcome matching claim (e.g., lipid levels for «supports heart health»), 8-12 week duration, published in peer-reviewed journal — gold standard evidence.
  • Observational studies and surveys. Cohort studies, case-control studies showing associations between supplement use and health outcomes, weaker than RCTs due to confounding, acceptable for supporting traditional use arguments and generating hypotheses.
  • Mechanistic studies and biomarkers. In vitro cell culture, animal models, human pharmacokinetic studies demonstrating biological plausibility of claimed benefits, necessary but insufficient alone — mechanism without clinical benefit is hypothesis not proven effect.
  • Traditional use documentation for ethnobotanicals. Monographs from WHO, ESCOP, German Commission E, historical texts describing traditional medicine applications, pharmacopoeial references, safety established through centuries of human consumption at traditional doses.

Curious fact: European Botanical Forum database documents 2000+ botanical ingredients with traditional use history, but only 200-300 have robust clinical trial evidence — manufacturers relying on tradition must prove historical use patterns match modern supplement formulation and dosing.

Dietary supplement registration in the EAEU requires careful navigation of ingredient safety assessment, quality standards, and claim substantiation rules. Understanding when traditional use data suffices versus when toxicological testing is mandatory, implementing robust GMP systems, and supporting claims with appropriate evidence levels ensures compliant market entry.
