Supplement Raw Materials
EU B2B Wholesale

EU Directive 2002/46/EC and Regulation (EC) 1925/2006 establish positive lists for vitamins and minerals but set no universal minimum purity for all supplement actives. In practice: amino acids (creatine, taurine) are traded to European Pharmacopoeia (EP) or Food Chemicals Codex (FCC) specifications requiring ≥99.0–99.5% assay. Vitamin C (ascorbic acid as E300) requires ≥99.0% per EU Reg. 231/2012. Botanical extracts are standardised to defined marker compounds (e.g. ashwagandha ≥5% withanolides). FDCM supplies CoA with HPLC-verified purity for every delivery.

A complete CoA must include: (1) Identity: product name, CAS number, batch/lot number, manufacturing date, expiry date; (2) Assay/purity: HPLC or titrimetric method result in %; (3) Specific impurities: e.g. for creatine – dicyandiamide ≤100 ppm and dihydrotriazine ≤100 ppm (both by HPLC); (4) Heavy metals: Pb, Cd, As, Hg by ICP-MS; (5) Microbiological: total plate count, yeast/mould, Salmonella neg./25g, E.coli neg./1g; (6) Physical: loss on drying, bulk density, particle size (mandatory for 200-mesh grades). FDCM includes all these parameters as standard with every shipment.

EFSA's 2015 scientific opinion (doi:10.2903/j.efsa.2015.4102) established: (1) Single doses up to 200 mg caffeine (approximately 3 mg/kg body weight) do not raise safety concerns for healthy adults; (2) Daily intakes up to 400 mg/day do not raise safety concerns; (3) For pregnant women: ≤200 mg/day total caffeine from all sources; (4) EU mandatory labelling: beverages exceeding 150 mg/L must state 'High caffeine content – not recommended for children or pregnant women'. These limits apply to caffeine from all sources, not just supplements.

Under Directive 2002/46/EC and Regulation 1169/2011, EU supplement labels must state: the name 'food supplement'; the list of nutrients or substances with quantities per recommended daily portion; the recommended daily amount (with warning not to exceed); 'keep out of reach of young children'; a statement not to use as a substitute for a varied diet; for caffeine ≥150 mg/L in beverages – the specific caffeine warning. Health claims are only permitted if listed in the EU Register of Authorised Nutrition and Health Claims (Reg. 1924/2006). Disease claims are prohibited.

The only authorised health claim for creatine in the EU (per Reg. 1924/2006 register) is: 'Creatine increases physical performance in successive bursts of short-term, high-intensity exercise.' Conditions: the claim may only be made for food providing ≥3 g creatine per daily portion. No cognitive performance claims are currently authorised. No disease-risk reduction claims exist. Unauthorised claims – such as 'builds muscle mass' or 'enhances recovery' – may not be used on EU supplement packaging.

Food grade (FCC – Food Chemicals Codex) sets minimum purity and impurity limits for food use. EP (European Pharmacopoeia) and USP (US Pharmacopeia) apply stricter limits for individual impurities, residual solvents, and heavy metals, with fully referenced analytical methods. For supplement raw materials, food grade is legally sufficient under EU law. EP-grade is not mandatory but is preferred by supplement manufacturers operating under GMP frameworks (e.g. EU Reg. 2023/2006) for product liability reasons. FDCM supplies food-grade materials; EP compliance is noted in the CoA where applicable.

Dicyandiamide (DCD) and dihydrotriazine (DHT) are synthesis by-products from the chemical production of creatine (from cyanamide + sarcosine). Both are specific impurity markers under EP and industry specifications, with limits of ≤100 ppm each. DCD is a nitrile compound; DHT is a creatine cyclisation product. At trace levels (≤100 ppm), neither has demonstrated toxicity in studies. However, high-impurity creatine (poor manufacturing) has been linked to GI discomfort. Always request HPLC data for both impurities – they are not captured by simple assay-only CoAs.

Mesh size defines particle diameter: 200 mesh = ≤75 μm (0.075 mm). Standard creatine is typically 80–100 mesh (≤177–149 μm). Smaller particle size provides three practical advantages: (1) Faster dissolution – 200 mesh dissolves approximately 40% faster in cold water at 20°C, reaching full dissolution in 30–60 seconds vs 90–120 seconds for 80 mesh; (2) Better uniformity in powder blends (reduced segregation by size difference); (3) Smoother texture in RTD beverages. The 200 mesh grade commands a slight premium but is standard in high-quality pre-workout formulations.

Technically, taurine is a sulphonic acid – a 2-aminoethanesulfonic acid (CAS 107-35-7) – not a true amino acid in the biochemical sense, because it lacks a carboxyl group (–COOH). It cannot be incorporated into proteins. Taurine is found at high concentrations in the brain (1–20 mM), skeletal muscle (12–18 g in the adult body), heart and retina. It serves as an osmoregulator, modulates intracellular calcium, and has mild GABA-A receptor agonist activity. Taurine is conditionally essential – biosynthesised from cysteine in the liver, but dietary intake improves status in athletes with high turnover.

The HPA (hypothalamic-pituitary-adrenal) axis is the central stress response system: the hypothalamus releases CRH → pituitary secretes ACTH → adrenal cortex produces cortisol. Chronic stress dysregulates this cascade, elevating baseline cortisol. Withanolide A from ashwagandha extract has been shown to inhibit Hsp90 (heat shock protein), which upregulates glucocorticoid receptor sensitivity, effectively dampening the cortisol response. In a 2012 RCT (Chandrasekhar, n=64), 300 mg BID ashwagandha extract reduced serum cortisol by 27.9% vs placebo (p<0.0001) over 60 days.

For capsule filling: creatine monohydrate 200 mesh is a free-flowing powder suitable for direct capsule filling at standard rates. Typical capsule size: 00 (0.91 mL) contains approximately 700 mg creatine. Target 3 g/day = 4–5 capsules. No excipients strictly needed, but 0.5% magnesium stearate reduces die-wall friction in tablet compression. For tablets: creatine requires a binder (5% HPMC or 3% PVP) and a disintegrant (2% croscarmellose sodium) for adequate hardness and dissolution. Hardness target ≥60 N for tablet integrity. Note: creatine is hygroscopic – all processing must be below 40% RH.

For a compliant pre-workout powder blend: (1) Start with actives: caffeine anhydrous (150–300 mg/serving), creatine monohydrate (3,000–5,000 mg), taurine (1,000–2,000 mg); (2) Add taste system: citric acid (500–1,000 mg for tartness), erythritol or sucralose for sweetness; (3) Add flow agents: silicon dioxide 0.5–1% to prevent caking; (4) Blend order: mix dry powders by density – heavy first (creatine), then medium (taurine), then light (caffeine, citric acid), then flow agents last; (5) Check segregation: caffeine is very fine – blend time 15–20 min in V-blender. Always validate by HPLC assay of final blend for caffeine uniformity (target ≤5% RSD).

Collagen synthesis requires two specific post-translational hydroxylation steps: prolyl hydroxylase (converts proline → hydroxyproline) and lysyl hydroxylase (converts lysine → hydroxylysine). Both enzymes require ascorbic acid (Vitamin C) as an essential cofactor and Fe²⁺. MSM contributes via a different mechanism: organic sulphur from MSM is a precursor for cystine (–S–S–) crosslinks in collagen and keratin, and for glutathione (the key intracellular antioxidant protecting collagen-producing fibroblasts). The MSM + Vitamin C combination thus targets the same pathway at two distinct molecular steps. Clinical evidence for the combination is limited but mechanistically sound.

Yes. EFSA's 2009 opinion on energy drink ingredients (taurine + d-glucuronolactone) specifically evaluated co-consumption with caffeine. Conclusion: no evidence of interaction between taurine and caffeine regarding diuretic effects, cardiovascular effects, or CNS stimulation at energy drink use levels. Taurine does not increase caffeine bioavailability or extend its half-life. From a formulation perspective, both are highly water-soluble, stable in acidic beverages, and compatible. The combination is the industry standard (250 mL energy drink: 80 mg caffeine + 400–1,000 mg taurine).

FDCM offers several raw materials commonly used as functional excipients: Xanthan Gum E415 (EUR 4.96/kg) – suspension stabiliser, thickener in RTD supplements (0.05–0.3%); Guar Gum E412 (EUR 3.09/kg) – thickener, texture modifier in gummy supplements (0.5–2%); Erythritol E968 (EUR 4.56/kg) – bulk sweetener (GI=0, 0.2 kcal/g), cooling effect useful in effervescent tablets; Citric Acid Anhydrous E330 (EUR 2.04/kg) – pH adjustment, chelating agent, effervescent system component; Inulin (EUR 7.50/kg) – prebiotic fibre, tablet filler/binder, fat replacer in bars. All supplied with standard CoA and EU food additive authorisation documentation.

Ashwagandha (Withania somnifera) has documented interactions worth noting: (1) Thyroid hormones: withanolides may upregulate T3/T4 synthesis – monitor in patients on thyroid medication (Sharma 2018); (2) Immunosuppressants: ashwagandha stimulates immune function (NK cell activity) – theoretically antagonises immunosuppressive drugs; (3) Sedatives/CNS depressants: mild GABA-A modulation – additive sedation possible; (4) Other adaptogens: ashwagandha + rhodiola rosea is a common combination (complementary anxiolytic + stimulant profile) with no known adverse interaction. Always advise supplement buyers to recommend end-consumers consult a healthcare provider if on prescription medication.

Creatine monohydrate is stable if stored correctly. Conditions: 15–25°C (room temperature); relative humidity ≤60% (critical – moisture converts creatine to creatinine by cyclisation, reducing potency); original sealed moisture-proof packaging; avoid direct sunlight (UV degrades slowly). Shelf life: 24–36 months from production date under these conditions. Opened 25-kg bags should be resealed immediately or transferred to a sealed container. Signs of quality loss: caking (moisture ingress – resample for creatinine content by HPLC), yellowish discolouration. Creatinine content should remain ≤100 ppm in a valid batch.

No. Ashwagandha (Withania somnifera) root and root extract are not listed in the EU Novel Food Catalogue as novel foods. They have a documented history of food use in the EU predating 15 May 1997, primarily through Ayurvedic dietary practices. Therefore, ashwagandha supplements can be marketed freely in EU member states as food supplements under Directive 2002/46/EC, without requiring Novel Food authorisation. However, some EU member states (e.g. Denmark, France) have imposed national restrictions on specific botanical supplements – always verify country-level rules before export.

Erythritol (CAS 149-32-6, E968) is a sugar alcohol produced by fermentation of glucose with Moniliella pollinis. Caloric value: 0.2 kcal/g (vs 4 kcal/g sucrose). Glycaemic index: 0. In supplement formulations, erythritol provides: bulk and mouthfeel in protein powders (2–10 g/serving), sweetness (60–70% of sucrose) without calories, a mild endothermic cooling effect (useful in effervescent tablets), and compatibility with all actives including caffeine. No laxative effect at typical supplement doses (unlike sorbitol/maltitol at >20 g/day). EFSA: quantum satis in most food categories; no ADI established.

Inulin is a β-fructan (degree of polymerisation 2–60) extracted from chicory root (Cichorium intybus). It is not digested in the small intestine and reaches the colon where it selectively stimulates Bifidobacterium and Lactobacillus species. EFSA-authorised health claim (per Reg. 1924/2006): 'Chicory inulin contributes to normal bowel function by increasing stool frequency.' Condition: ≥12 g chicory inulin per day. Prebiotic claims ('feeds beneficial gut bacteria') are not currently authorised as health claims in the EU but may be used as factual descriptions if substantiated. FOS fraction of inulin (dp 2–8) ferments faster than long-chain inulin (dp >23).

Withanolides are a class of 28-carbon steroidal lactones unique to Withania somnifera – over 300 have been identified. The pharmacological activity is primarily attributed to withanolide A, withaferin A and withanone. The ≥5% withanolides specification is measured by UV-spectrophotometric method (absorbance at 227 nm after alkaline hydrolysis), which quantifies total withanolide content as a group. This is the industry standard. More precise characterisation uses HPLC-MS, which can identify individual withanolides. The KSM-66® and Sensoril® branded extracts are standardised to specific withaferin A:withanolide A ratios, but food-grade bulk extract at ≥5% UV is the standard for B2B procurement.

The five most common quality issues: (1) Assay below label claim – detected by HPLC; (2) Heavy metal contamination (especially Pb, Cd in botanical extracts like ashwagandha) – detected by ICP-MS; (3) Microbiological contamination (especially in plant extracts with high TPC) – detected by ISO 4833-1; (4) Specific impurities (dicyandiamide in creatine, related compounds in caffeine) – detected by HPLC with specific gradient method; (5) Adulteration (wrong raw material substituted – e.g. gluconate passed off as creatine) – detected by FT-IR or NMR identity test. Always request the full CoA before first purchase, and ask for HPLC chromatograms (not just the result) for critical actives.
