Skip to Main Content

Nutritional and composition analysis provides quantitative information about the nutrients and other measurable components present in natural health products, supplements and ingredients.

Testing can support product development, formulation verification, ingredient assessment, finished-product specifications and investigation of unexpected composition results.

PBR Laboratories provides nutritional and composition testing support from Edmonton for applicable natural health products, supplements and related ingredients across Alberta, Western Canada and Canada.

The appropriate analytical program depends on what the product contains, which components need to be measured, the product matrix and what decision the laboratory result must support.

What Is Nutritional & Composition Analysis?

Nutritional and composition analysis measures selected components of a product or ingredient to provide quantitative information about its composition.

Depending on the matrix and analytical objective, testing may include:

  • protein;
  • carbohydrates;
  • dietary fibre;
  • sugars;
  • total fat;
  • fatty acids;
  • cholesterol;
  • calcium;
  • iron;
  • sodium;
  • potassium;
  • magnesium;
  • moisture;
  • ash;
  • selected vitamins.

PBR’s current service catalogue documents these nutritional and compositional analytical capabilities for applicable matrices.

The purpose of testing should be defined before selecting the analytical panel.

What Decisions Can Nutritional & Composition Testing Support?

Laboratory results may help answer questions such as:

  • Does the product have the expected composition?
  • Does an incoming ingredient align with its purchasing specification?
  • Is the measured protein content consistent between lots?
  • Has moisture changed during storage or manufacturing?
  • Does the finished product align with selected compositional specifications?
  • Does an unexpected result require formulation or manufacturing investigation?
  • Is independent analytical verification needed before a supplier or product decision is made?

PBR’s decision framework requires laboratory testing to connect the matrix, analytical parameter and result to a real product, supplier or quality decision.

  • raw-material assessment;
  • finished-product investigation.

Nutritional Analysis vs Composition Analysis

What is the difference between nutritional analysis and composition analysis?

Nutritional analysis focuses on nutrients and related components used to characterize a product’s nutritional profile.

Composition analysis is broader. It can involve measuring selected components of a raw material or finished product against a formulation, purchasing specification or internal quality target.

For example:

A protein supplement manufacturer may need:
protein + moisture + sugars

while an ingredient supplier may need:
protein + ash + selected minerals

The appropriate testing panel depends on the decision the result needs to support.

Nutritional Analysis Is Not the Same as Medicinal Ingredient Potency Testing

A nutritional analysis panel and a medicinal-ingredient potency test do not necessarily answer the same analytical question.

Medicinal-ingredient testing may require:

  • product-specific analytical methods;
  • appropriate reference materials;
  • target-specific sample preparation;
  • specific concentration ranges;
  • matrix-specific method suitability.

PBR’s verified service catalogue supports defined nutritional parameters and selected vitamins, but it does not provide support for a general claim that all medicinal-ingredient potency testing is available.

Tell PBR exactly which component needs to be measured and what decision the result must support.

Wet Chemistry vs Calculation-Based Nutritional Analysis

PBR’s existing service catalogue distinguishes between wet-chemistry nutritional facts testing and computational nutritional facts testing.

Wet Chemistry

Wet-chemistry testing involves laboratory measurement of selected parameters in the submitted sample.

This approach may be appropriate where:

  • independent analytical verification is required;
  • ingredient variability matters;
  • the measured value will support a specification;
  • the finished product requires direct characterization;
  • an unexpected composition result is being investigated.
Calculation-Based Analysis

Calculation-based analysis uses formulation or ingredient information rather than directly measuring every component in the finished sample.

This approach depends heavily on:

  • formulation accuracy;
  • ingredient data;
  • supplier information;
  • consistency of raw materials.
Which approach is appropriate?

The answer depends on how the result will be used.

Where actual product composition must be independently verified, direct analytical testing may answer questions that calculation alone cannot.

Ingredient Composition Testing

Composition testing can be performed on applicable incoming ingredients where the analytical result supports:

  • supplier qualification;
  • ingredient acceptance;
  • purchasing specifications;
  • formulation inputs;
  • investigation of ingredient variability.

Potential parameters may include:

Protein | Moisture | Ash | Fat | Selected Minerals | Other Applicable Components

The correct testing panel should reflect the material and the supplier or manufacturing decision being made.

Finished Product Composition Testing

Finished-product composition analysis can help determine whether selected analytical parameters align with the expected formulation or established product specification.

Testing may support:

  • finished-product characterization;
  • formulation verification;
  • comparison between batches;
  • specification review;
  • investigation of unexpected results.

The laboratory result should be interpreted against the applicable product specification rather than as a standalone number.

What Happens When a Composition Result Does Not Match the Specification?

An unexpected analytical result does not automatically identify the reason for the difference.

An investigation may need to consider:

  • raw-material variability;
  • supplier information;
  • formulation records;
  • weighing or blending;
  • product homogeneity;
  • manufacturing conditions;
  • moisture changes;
  • sample representativeness;
  • analytical method;
  • matrix effects.

Repeated testing alone may not explain why the original result differed from expectations.

The appropriate follow-up should be based on the product, analytical parameter and quality decision.

Sampling Matters in Nutritional & Composition Testing

A laboratory result describes the submitted sample.

For powders, blended formulations and heterogeneous ingredients, the sample must adequately represent the material if the result will be used to make a lot-level or batch-level decision.

Common sampling risks include:

  • collecting from only one location in a large lot;
  • submitting too little material;
  • poorly designed composite sampling;
  • not accounting for product segregation;
  • failing to retain individual samples for investigation.

PBR’s decision framework specifically identifies representativeness and sampling design as factors that affect how confidently a laboratory result can be applied to a larger lot.

Ask PBR about sample requirements before submitting your product.
