Trace Metals in Supplements and Foods


Trace metals are naturally occurring elements in the earth’s crust and are found throughout nature, including in our food supply. There is no strict definition for a trace metal, but they’re generally considered to be high density, literally trace metals, as in those elements in the metals section of the periodic table of elements. According to the FDA, our air, water, and soil, all contain trace metals that enter our food supply.1 Many of these metals, like iron and zinc, are beneficial and essential in the diet.

Given that some metals naturally occur in soil, even organic soil, it is often the case that these metals make their way into fruits, vegetables, and other crops grown naturally.  Metals are also present in plants that are used to create animal feed, resulting in their presence in animal products and dairy. The FDA’s Total Diet Study is an ongoing monitoring program of over 800 contaminants and natural elements in the average U.S. diet. Based on FDA data (from 2006-2013) common foods that contain trace amounts of trace metals include:

Cucumbers: 0.011 mcg/g arsenic on average

Spinach: 0.004 mcg/g lead on average

Strawberries: 0.015 mcg/g cadmium on average

Milk, 2%: 0.0003 mcg/g lead on average

Turkey breast: 0.006 mcg/g arsenic on average

Lamb chop: 0.002 mcg/g lead on average

Since we recognize that metals are naturally occurring in some of our ingredients, we regularly test all products for trace metals and toxins so that we can confidently state that our products are 100% safe for consumption based on the strict standards set by the FDA. To also help ensure safety, we only use high quality non-GMO ingredients.

F-Factor’s mission is to educate so people can make informed decisions. Because there is a lot of misinformation on the internet and on social media, we are taking this opportunity to present an accurate summary of trace metals found naturally in foods and in other natural ingredients, so that you can make an informed decision about the foods you are eating.
