Food, Beverages & Supplements
At Brooks Applied Labs, we specialize exclusively in testing for heavy metals at ultra-low-levels for:
- Dietary Supplements
Our laboratories, instruments, methods, and staff are all strictly committed to providing the most precise and accurate data for heavy metals available.
Services We Offer:
CA Prop. 65 requires businesses (i.e., manufacturers, distributors, retailers) to notify consumers through proper labeling if their products contain any of the listed chemicals in excess of what has been determined to a safe level of daily exposure.
Of particular concern in natural products is the presence of naturally occurring heavy metals, such as arsenic, cadmium, lead, and mercury (the Big Four), in addition to a few other elements that can be toxic at even very low levels.
Brooks Applied Labs offers businesses in the natural products industry California Prop. 65 analysis to certify that the levels of heavy metals in their products are below the limits established by CA Prop. 65 and to protect them from potentially frivolous litigation.
We even offer metals speciation analyses to distinguish between what have been deemed safer metals species and far more toxic metals species, such as tests for:
- inorganic arsenic
- hexavalent chromium
Contact us today to learn more about how our testing services can certify your products to be low in heavy metals and compliant with CA Prop. 65.
Naturally occurring arsenic in the soil can be taken up by plants of all kinds and become incorporated into final products using even the most carefully cultivated ingredients. Moreover, arsenic-based wood preservatives, insecticides, and fungicides were used extensively until very recently and most fruit orchards are still heavily contaminated by past use – even if they are adhering to strict organic standards today.
Brooks Applied Labs offers specialized testing services to distinguish inorganic arsenic from other forms of arsenic in:
- dietary supplements
- food (such as rice and mushrooms)
- beverage products (such as apple juice and rice-based drinks)
- and many more specific organic and inorganic arsenic species!
Contact us today to learn more about how our testing services can certify your products to be low in inorganic arsenic.
When naturally occurring mercury or human-caused contamination reaches rivers, lakes, or the ocean, microorganisms convert it into methylmercury, which can bioaccumulate in the wildlife and then biomagnify up the food chain. Large fish can have methylmercury concentrations more than million times greater than the surrounding water, and when people eat those fish they are at risk of mercury poisoning.
More critically, methylmercury is especially detrimental to the neurological development of fetuses and women who are pregnant are recommended to avoid eating any fish or products that contain fish oil that may be high in methylmercury concentrations.
Brooks Applied Labs is recognized as a world leader in analyzing for methylmercury concentrations and has decades of experience providing laboratory testing services to:
- researchers in medicine
- Updating the methodology used to test for elemental impurities in dietary supplements to include procedures that rely on modern analytical technologies
- Establishing limits for acceptable levels of elemental impurities, including arsenic, cadmium, lead, and mercury, in dietary supplements.
USP <2232> provides proposed limits for elemental metal contaminants in dietary supplements and dietary ingredients. Limits for individual components and permissible daily exposure (PDE) are provided for arsenic (inorganic), cadmium, lead, and mercury (methylmercury).
Tests for inorganic arsenic and methylmercury are required if the levels of total arsenic or total mercury are in excess of the proposed new acceptable PDE limits.
Brooks Applied Labs offers specialized testing services to establish that dietary supplements are compliant with these new standards for elemental impurities and metals speciation analyses when necessary.

Many natural ingredients accumulate small amounts of heavy metals from the environment (i.e., the soil and water), but determining exactly how much of a specific metal is in a product requires extremely sensitive analytical techniques. Perhaps even more importantly, since natural levels can often be in the low parts-per-billion range, laboratories that are not experienced with the proper analytical methods can easily contaminate samples.
At Brooks Applied Labs, we specialize exclusively in testing for heavy metals at ultra-low-levels for the environmental, energy, pharmaceutical, and food industries. Our laboratories, instruments, methods, and staff are all strictly committed to providing the most precise and accurate data for heavy metals available.
Using the latest in microwave digestion and ICP-MS technologies, we provide heavy metals testing services to companies that manufacture, distribute, and retail a variety of consumer products. Our ultra-sensitive analytical method was recently accepted by the AOAC Expert Review Panel on Heavy Metals as an AOAC First Action Method. Final Action Status will be granted once the multi-laboratory validation study is completed (expected September 2017).
Our Ultra-Low Detection Limits:*
|Heavy Metal||Limit of Quantification|
*Lower quantitation methods available for specific matrices.
Brooks Applied Labs has some of the lowest detection limits commercially available to our clients. View our MDL & MRL Table.
