Every Kirkman product is backed by our Ultra Tested® programme — rigorous testing of both raw ingredients and finished products, with a Certificate of Analysis available for every single item we make. We screen for microbial contamination, nine heavy metals, and other environmental contaminants relevant to each product and its ingredients — not because regulations require it, but because your trust requires it.

What Does Ultra Tested® Mean?

Ultra Tested® is Kirkman's answer to a simple question: how do you know a supplement is what it claims to be?

It starts before manufacturing even begins. Every raw ingredient is tested on arrival — before it ever touches a Kirkman formulation. Then, after blending, manufacturing and encapsulation, we test again. Nothing ships until it's been verified twice.

That double-checkpoint is what sets Ultra Tested® apart and it's why every product meets our quality and purity specifications before it ever reaches you.

The Ultra Tested® programme includes:

Raw ingredient testing — before formulation

Finished product testing — after manufacturing

Comprehensive microbial screening

Testing for nine heavy metals

Environmental contaminant testing

Independent third-party laboratory verification

Confirmation against Kirkman's own quality specifications

A Certificate of Analysis for every product, every time

A Certificate of Analysis for Every Product.

What is a Certificate of Analysis (COA)?

A Certificate of Analysis (COA) documents the laboratory testing performed on a product and confirms whether it meets Kirkman's established quality specifications.

Why does Kirkman provide a COA?

Transparency shouldn't mean asking customers to take our word for it—it should mean showing our work.

That's why Kirkman provides a Certificate of Analysis (COA) for every product, giving customers clear visibility into the testing behind every supplement they choose for themselves and their families.

What does a COA include?

Depending on the product, a COA may include results for:

Microbial testing
Heavy-metal testing
Ingredient or product identity
Potency or strength
Purity specifications
Other applicable quality tests

No marketing claims. Just documented evidence of how each product was evaluated — available for every product, every time.

Testing Beyond the Ingredient List

An ingredient list tells you what a product is supposed to contain. It doesn't tell you where those ingredients have been or what they picked up along the way.

Contaminants can enter at almost any stage:

Soil
Water
Harvesting
Transportation
Storage
Processing
Manufacturing equipment
Packaging materials

A supplier's Certificate of Analysis can offer useful information. But Kirkman doesn't take it on faith.

We test raw ingredients before they ever enter a Kirkman formulation. Then we test again; after blending, processing and encapsulation are complete. Nothing moves forward on someone else's word alone.

That's what a real quality checkpoint looks like. Not once. Twice.

Comprehensive Microbial Testing

Microbial testing helps Kirkman evaluate manufacturing hygiene, ingredient quality, product stability, and the potential presence of unwanted microorganisms.

Our microbial testing programme includes analysis for:

Total Aerobic Microbial Count

Total Aerobic Microbial Count, or TAMC, measures the total number of viable aerobic bacteria detected in a product.

This testing provides an indication of overall microbial quality and manufacturing hygiene.

Total Yeast and Mold Count

Total Yeast and Mold Count, or TYMC, measures viable yeasts and molds within a product.

Monitoring yeast and mold is particularly important for botanical and plant-derived ingredients, which may be exposed to microorganisms during growing, harvesting, processing or storage.

Elevated levels may also indicate potential spoilage or reduced product stability.

Enterobacteriaceae

Enterobacteriaceae are a family of bacteria that includes environmental organisms and organisms associated with fecal contamination.

Testing can help identify possible sanitation or contamination issues arising during harvesting, ingredient handling or manufacturing.

Escherichia coli

Testing for E. coli helps identify potential fecal contamination.

Its detection may indicate a significant breakdown in sanitation, ingredient handling or manufacturing controls.

Pseudomonas aeruginosa

Pseudomonas aeruginosa is an opportunistic microorganism that can survive in moist environments.

Testing may be particularly relevant for liquid formulations and products manufactured or handled in environments where moisture is present.

Salmonella

Salmonella is a significant foodborne pathogen that can cause illness even when present at low levels.

Kirkman tests for its presence as part of our microbial quality-control programme.

Staphylococcus aureus

Staphylococcus aureus may be introduced through personnel or the manufacturing environment.

Certain strains can produce toxins, making its detection an important component of microbial testing.

Coliforms

Where applicable, Kirkman also tests products for coliform bacteria.

Coliform testing can provide an additional indication of sanitation, ingredient handling and manufacturing conditions.

Testing for Nine Heavy Metals

Many supplement testing programmes focus primarily on four widely monitored heavy metals:

Lead

Arsenic

Cadmium

Mercury

Kirkman’s Ultra Tested® programme evaluates a broader panel of nine metals to provide a more comprehensive contaminant profile.

Kirkman’s nine-metal panel includes:

Lead

Arsenic

Cadmium

Mercury

Aluminum

Chromium

Tin

Antimony

Barium

Testing for this wider group gives Kirkman additional information about potential contamination associated with soil, water, botanical materials, mineral ingredients, marine ingredients, manufacturing equipment and packaging.

Why We Test for These Metals

Lead

Lead is widely present in the environment and may enter ingredients through contaminated soil, water or processing conditions. Monitoring lead is important because excessive exposure can affect neurological development, kidney function and other body systems.

Arsenic

Arsenic occurs naturally in soil and water and may be present in botanical, rice-derived and marine ingredients. Kirkman tests for arsenic as part of our assessment of potential environmental contamination.

Cadmium

Cadmium may accumulate in plants grown in contaminated soil. Because it can remain in the body for extended periods, monitoring cadmium is an important part of ingredient and finished-product testing.

Mercury

Mercury may be a concern in certain marine-derived ingredients and mineral materials. Testing helps Kirkman identify potential contamination before a product is released.

Aluminum

Aluminum occurs naturally in some soils, plants, clays and minerals. It may also be introduced through processing or manufacturing equipment. Including aluminum in the testing panel provides additional information about the purity of relevant ingredients and finished products.

Chromium

Chromium can occur naturally in mineral ingredients and may also be present through environmental or manufacturing sources. Kirkman evaluates chromium levels as part of our broader heavy-metal testing programme.

Tin

Tin may be introduced through certain metal containers, processing equipment or packaging materials. Testing helps monitor whether unexpected tin contamination is present.

Antimony

Antimony may originate from environmental sources, manufacturing equipment, packaging materials or industrial processing. Its inclusion expands the range of potential contaminants evaluated under the Ultra Tested® protocol.

Barium

Barium occurs naturally in some soils and mineral ingredients. Testing for barium provides additional information about products containing ingredients that may be exposed to mineral contamination.

Why Test Both Ingredients and Finished Products?

Testing raw ingredients provides an important quality checkpoint before manufacturing begins.

Finished-product testing provides another checkpoint after ingredients have been:

Measured
Blended
Processed
Encapsulated
Packaged

Testing at both stages helps Kirkman evaluate whether the final product continues to meet our established specifications after manufacturing is complete.

It also helps identify potential issues that may not be visible from reviewing an ingredient supplier’s documentation alone.

Third-Party Laboratory Testing

Kirkman uses third-party laboratories as part of our testing and quality-control programme.

Independent laboratory testing provides analytical results that Kirkman can use to evaluate ingredients and finished products against established specifications.

This allows us to verify product quality using documented test results rather than relying only on supplier assurances or ingredient labels.

ULTRA TESTED®

Every Product Tested. Every Product Documented.

Ultra Tested® is not simply a phrase placed on a label. It represents Kirkman's commitment.
