What Are We Testing?

Quality Testing - Assuring Purity of Metagenics Products

Active ingredients are an expectation in natural medicines, yet impurities should not be present. We understand both Practitioners and patients need transparency around testing which is why we want to show you impurities that are tested within our product range, along with why we test them and what you need to know about them.

Elemental Impurities

Why test? Metagenics tests for the presence of heavy metals (elemental impurities) such as arsenic, lead, cadmium and mercury which might be detected in certain ingredients. These metals are a natural part of the earth's crust and can be found in most soils around the world, and therefore has potential to be within plants and herbs. Testing for heavy metals is performed using inductively coupled with plasma mass spectrometry which allows detection for nonorganic materials at part-per billion concentrations.*

What are we testing?

Excess lead exposure and lead toxicity has been associated with health issues affecting the neurological, renal, gastrointestinal, hematologic, and cardiovascular systems.1
Mercury can cause toxic effects to the nervous system, digestive and immune systems, lungs, kidneys, skin, and eyes. Testing to ensure mercury levels are below the recommended rate ensures consumers are protected from the toxic risks of mercury.2
Testing for arsenic ensures products do not contain more than the established acceptable level of arsenic. Long-term, excessive exposure to arsenic has known health risks.
Excess cadmium exposure and accumulation can result in detrimental effects on the kidneys, as well as skeletal and respiratory systems; it is also classified as a human carcinogen by various agencies.3


Why test? Micro testing is completed to ensure adherence to the TGA's Microbiological Standards for Medicines Order (TGO 100). This is to ensure finished products and raw materials are not contaminated by pathogens and are manufactured in a sanitary environment.

What are we testing?

This testing can help ensure there is no contamination by bacteria. Members of the Bile-tolerant gram-negative family include Enterobacteriaceae, Pseudomonads and Aeromonas.6
Exposure to mould is associated with a variety of health issues including allergic reactions and respiratory problems, while certain groups are more susceptible to moulds (i.e. immune compromised or those with pre-existing allergies or respiratory disease).4 Testing for yeast is equally important due to its pathogenic nature, especially amongst immune compromised populations.5
E.coli can cause acute intestinal illness in healthy individuals and more serious health risks in young, elderly, or immunocompromised individuals.7
Salmonella spp. can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella spp. often experience fever, diarrhea, nausea, vomiting and abdominal pain.8
Pathogens, also known as infectious agents, are organisms that may produce disease. Testing for objectionable organisms ensures that pathogens are not present.
Staphylococcus aureus is a common bacteria that frequently exists on the skin or in the nose. S, aureus can cause a range of illnesses, from minor to major infections, some of which can be life-threatening.9 Recent developments of antibiotic-resistant strains, like MRSA, highlight the importance of testing for staph.

Physical Attributes

We do a number of checks on the physical attributes of all capsules, tablets, liquids and powders - with some checks occurring every 30 minutes! Metagenics is a premium product range, and we won't settle for anything less than perfect.

Physical Attributes
Always read the label. Follow the directions for use. If symptoms persist, consult your healthcare professional.
