FAQs on Heavy Metals

Unfortunately, no. As WebMD states “Heavy metals, like arsenic, lead, mercury, and others, are all around us. They’re in the ground we walk on, in the water we drink, and in the products we use every day. But high levels of most heavy metals can cause health problems.”⁽¹⁾

While totally eliminating exposure to heavy metals is not possible, we can make efforts to limit the heavy metals we get in our diet.

There is no single answer to this question. Different agencies and organizations have come to varying conclusions on how much of each heavy metal is considered acceptable to consume on a daily basis.

In addition, different population of people will have different levels of heavy metals that could cause issues.   For example, infants and children would want to consume lower amounts of heavy metals than adults.

For these reasons, each person should do their own research and consult with their health care provider to determine what limits they want to apply to their heavy metal consumption.

To help provide a general idea, here is some guidance from a few different agencies…

FDA = Food and Drug Administration
AHPA = American Herbal Products Association
USP = United States Pharmacopeia
PDE = permitted daily exposure
NHP = Natural Health Products

mcg = micrograms
1 Microgram = 1/1,000,000 of a gram – yep, 1 millionth of a gram – so we are talking very small numbers.

Again, we highly encourage you to do your own research to determine heavy metal levels that you are comfortable with. The links in our reference section should help you get started.

Sure! There is a lot of talk about lead levels in foods, so it can be helpful to see some testing of common foods, so you have a point of reference when looking at lab testing.

Obviously, levels will vary greatly based on where the food is grown, how it is grown and the manner in which it is processed.  

One of the best primary sources we have found for looking at lead levels in food is The US FDA Total Diet Study (2006-2013). The FDA samples a wide variety of foods over years and reports on, among other things, heavy metal levels in their testing.

To give you a point of reference, below we show a variety of foods from the FDA Total Diet Study ⁽⁷⁾ and both their average and maximum lead levels that were observed in the study, as calculated for a serving.

While organic food has numerous benefits and is free of pesticides and other chemicals, it can still contain heavy metals. Remember, heavy metals are in the soil and water, so even something grown in an organic manner can still contain heavy metals.

We require all of our ingredient suppliers to provide lab assays showing that they meet or exceed any established federal guidelines for heavy metals. In addition, throughout the year we do spot testing of our finished products.

Sure, when doing our spot testing we are looking at levels of four heavy metals…

Lead, Arsenic, Cadmium, Mercury

Since 2022 we have been doing increased spot testing for lead.

As you look at heavy metal lab testing results for any specific product, you will notice that the levels vary slightly from test to test.

All of our products are all natural and as with any natural product, there will be a slight variance in nutrients, polyphenols, flavonoids and heavy metals from batch to batch.

We provide consumers with multiple lab test results to provide an indicator of how previous batches have tested, these are not intended to show the exact levels of the specific batch you will receive.
