Powdered Supplement Testing in Alberta & Across Canada
Home / Natural Health Product Testing / Powdered Supplement Testing
Powdered natural health products can present analytical challenges related to blend uniformity, ingredient variability, microbial quality, moisture, water activity and representative sampling.
Depending on the formulation and specification, testing may include:
microbiological testing;
Applicable United States Pharmacopeia microbiology methods.
Nutritional and composition analysis.
Moisture.
Water activity.
Heavy metals and contaminants.
Mycotoxins where ingredient risk is relevant.
Raw-material testing.
Finished-product testing.
Stability and quality monitoring.
PBR Laboratories supports powdered supplement manufacturers, ingredient suppliers, brand owners, importers and quality teams from Edmonton across Alberta, Western Canada and Canada.
The practical question is:
Does the submitted powder represent the product or lot well enough to support the quality decision being made?
The analytical program should be selected according to the ingredients, matrix, specification and intended decision, not simply because the product is a powder.
Why Are Powdered Supplements Different?
Powders may behave differently from liquids, capsules or tablets because ingredients can vary in:
Particle size.
Density.
Moisture.
Flow characteristics.
Concentration.
Distribution within the blend.
These differences can affect:
Sampling.
Blend uniformity.
Microbiological results.
Composition results.
Contaminant distribution.
That is why powder testing should begin with both the analytical target and the sampling question.
Microbiology Testing for Powdered Supplements
Depending on the product and specification, microbiological testing may include:
Total aerobic microbial count.
Yeast and mould.
Bile-tolerant Gram-negative bacteria.
Escherichia coli.
Salmonella species.
Staphylococcus aureus.
Pseudomonas aeruginosa.
PBR also supports applicable microbiological testing using United States Pharmacopeia <61>, <62>, <2021> and <2022>, depending on the product category and specification.
PBR supports Canadian companies requiring microbiological, compositional, contaminant and quality testing for powdered natural health products.
The goal is not simply:
“What result did the laboratory report?”
It is:
“Does the submitted powder represent the batch, what does the result mean against the specification, and what decision should come next?”
Powdered supplements may require microbiological, nutritional, moisture, water-activity, heavy-metal and mycotoxin testing depending on the ingredients and specification. Because powders can segregate and may not be homogeneous, representative sampling is critical when a laboratory result will support a batch-level decision.
Frequently Asked Questions
Depending on the formulation, testing may include microbiology, nutritional composition, moisture, water activity, heavy metals, mycotoxins and other applicable quality parameters.
Yes. Applicable testing may include microbial enumeration, yeast and mould and specified microorganisms depending on the product and specification.
Depending on the product category and specification, applicable testing may involve United States Pharmacopeia <61>, <62>, <2021> and <2022>.
PBR's documented nutritional capabilities include protein analysis for applicable matrices.
Moisture measures how much water is present. Water activity describes how available that water is.
Potentially, where botanical, grain-derived or other agricultural ingredients create a relevant mycotoxin risk.
Powders can segregate and vary throughout a batch. One small sample may not represent the entire lot.
Selected parameters within PBR's analytical scope can be tested independently. The exact parameter and method should be reviewed first.
No. Manufacturing, blending, other ingredients, moisture, storage and sampling can affect the finished product.
Yes. PBR supports clients throughout Alberta, Western Canada and Canada.
