Sadly, many collagen powders are tainted with lead and other heavy metals, and some may even have non-collagen ingredients in them, called fillers. You should definitely stick to collagen without lead and fillers if you want to be as healthy as possible. The following collagen powders are tested for lead and other heavy metals, and they also are tested for pesticides as well.

Collagen and lead contamination
If you want the best collagen without lead and fillers, you should insist on lab testing from the brand you choose. Many of the top collagen brands have been tested for heavy metals like lead and arsenic. We’ve recommended only brands with good results on these tests. Here are their heavy metals results, plus their pesticide results:

Pesticide residue in collagen powder
Collagen powder has a pesticide problem. The collagen is made from cows, usually, and the cows were given feed that is covered in pesticide residue. Then that pesticide gets into your collagen powder. No good! Fortunately, organic, grass-fed cows don’t really have this problem. In addition to being better for your health, it’s also much nicer to the cow. And we have proof that certain collagen powders don’t have pesticides in them, since they are independently lab tested to be free of pesticides. We have recommended collagen powders that have made their pesticide and lead tests both visible, ideally with independent certification.
Avoiding fillers in your collagen powder
Lead and fillers could both be problems in collagen powder. Make sure to read the side of the label and don’t get anything that advertises extra junk that isn’t collagen. Fillers are a big issue in the protein powder industry, so you should be careful of your collagen brand. You don’t want any unnecessary fillers. The brands we recommend have done a great job being transparent and ethical about delivering a good quality collagen product, so we are pretty confident they won’t lie to us about using fillers either.
The bottom line
Tons of people use collagen powder to help their skin, their joints, and their digestive systems. It would be a shame if they were ingesting lead and fillers in their collagen powder all this time. So make sure to get a collagen powder that you can trust to be free of these things!
