Third-party lab tested - every batch, every ingredient, no exceptions

At Systler, we believe buyers should never have to take a supplier's word for product quality. That's why every batch of every botanical ingredient we export is tested by an independent, accredited third-party laboratory before it leaves our supply chain.

The Certificate of Analysis (COA) you receive is not a template or a generic document. It is a batch-specific analytical report from a named accredited laboratory, covering all critical safety and quality parameters.

Heavy metals testing

Heavy metal contamination is the most critical safety concern for botanical supplements in the US and EU markets. We test every batch for all four regulated heavy metals:

• Lead (Pb): <0.5 ppm (Psyllium) / Meets USP <232> limits for all botanicals
• Arsenic (As): <0.2 ppm (Psyllium) / Meets USP <232> limits
• Cadmium (Cd): Tested and reported per batch
• Mercury (Hg): Tested and reported per batch

Testing methodology follows ICP-MS (Inductively Coupled Plasma Mass Spectrometry) - the gold standard for trace metal analysis.

Microbial safety testing

Microbial contamination is tested to ensure products are safe for supplement manufacturing use:

• Total Aerobic Plate Count (TPC)
• Total Yeast and Mould Count
• E.coli (absence per gram)
• Salmonella (absence in 25g)
• Total Coliforms
• Staphylococcus aureus (on request)

Purity and identity testing

• Identity: Botanical identity confirmed by TLC/HPTLC or organoleptic methods
• Purity: Product-specific purity assay (e.g. psyllium husk purity ≥99%, withanolide content for ashwagandha)
• Moisture: Karl Fischer titration or loss on drying
• Ash content: Total ash and acid-insoluble ash
• Particle size: Mesh analysis for powder products

Optional extended testing

Available on request for specific buyer requirements or market compliance:

• Multi-residue pesticide screen (EU MRL / USDA NOP)
• Aflatoxin testing (B1, B2, G1, G2)
• Ochratoxin A
• Allergen ELISA panel
• Nutritional panel (per 100g / per serving)

About our testing laboratories

All testing is carried out at NABL-accredited (National Accreditation Board for Testing and Calibration Laboratories) third-party laboratories in India. NABL accreditation is the Indian equivalent of ISO/IEC 17025 - the international standard for laboratory competence.

COA documents show the laboratory name, NABL accreditation number, test date, batch number, analyst signature, and results. They are available to buyers prior to or at the time of shipment.
