Collagen is the most common and abundant of your body’s proteins, comprising about 25 percent of the total protein in your body, and up to 80 percent of your skin, in terms of dry weight.

It’s found specifically in the connective tissues throughout your body, from your muscles, bones and tendons to your blood vessels and digestive system. As a compound of essential amino acids, there’s only one way to get collagen; your body can’t produce it, so you must obtain it through your diet. Most people, however, will simply reach for a collagen supplement rather than boiling down chicken feet or beef bones for a homemade collagen-rich broth.

Recent laboratory testing stirred up controversy with popular collagen and bone broth products results revealing potential contaminants — including antibiotics, prescription drug metabolites, parabens, steroids and insecticides.

The collagen products in question were selected based on their popularity and sales ranking on Amazon.com, and all were nonorganic. The results indicate that if you are consuming bone broth or collagen products that are not organic you are likely getting CAFO (concentrated animal feeding operations) byproducts. 

So, what do these results mean? In a nutshell, if a collagen or bone broth protein product is not certified organic, it is very likely the primary ingredients are sourced from animals raised in CAFOs. If you do not consume factory farmed/CAFO meats, you likely should not be consuming CAFO collagen and bone broth products.
