Collagen heavy metal content

Posted by njx58 @njx58, Sep 26, 2025

In another thread, some people were discussing the heavy metal content of collagen peptide supplements. I asked Keith McCormick about his own OsteoNaturals supplement. He sent me the Gelita lab report. I'll summarize the key tiems. For each metal, I'll list the desired specification, and the actual result.

Cadmium: < = 0.10 ppm, < 0.10 ppm
Mercury: < = 0.02 ppm, < 0.02
Arsenic: < = 0.7 ppm, < 0.7 ppm
Lead: < = 0.50 ppm, < 0.01 ppm

So, it is not free of heavy metals, but it doesn't have a lot. What I don't know is what levels are acceptable. Most of the brands contain metals. Vital Proteins was sued a few years ago; they are owned by Nestle, a notorious company for ignoring consumer health. Of course it's a little suspicious that the OsteoNaturals lab test was performed by Gelita itself - the maker of Fortibone.

I am now thinking that the benefit of using collagen peptides, which is small to begin with, is not worth it. I need to do some more research.

@nycmusic Hello again. I am nearly 6mo out from my last (rad) treatment. Yesterday was a marathon check up: labs, APRN check-in, pre-op exam for TKR, EKG, bilateral mamo post surgery.
I asked APRN if I should be taking collagen after a few seconds of thought she said, yes that it would probably help with my small joint pain I experience upon waking. When I asked about a brand she said any kind would do, not to bother going to a health food store, but any place that sells OTC products would do.
I’m now wondering if collagen needs a carrier like calcium does to get into the system and do its work.
I see too many popup ads by “medical professionals” each one touting their own brand after a loooong presentation that has pressure to buy now, then double your order, etc. I have become a skeptic of any of these ads and immediately delete.
I’d be interested in hearing your thoughts on this, before I purchase

@pat9892 how I wish I had clear answers ! I’m planning to get collagen from food- protein and bone broth in particular…like yourself, i don’t trust the ads….for me, easy slow exercises/ stretches before getting out of bed erases early stiffness..no fancy guide, just wiggle everything gently..i start with toes/feet and work my way up. I am interested in skin creams with collagen/peptides—they can be found on Amazon, so I’ll try Olay’s version, inexpensive and non-greasy… trial and error, keep trying…wishing you all the best health !

I have tried a few brands of collagen, hoping for a hair/skin benefit and perhaps a bone one too, but deep down, I think there is a lot of hype around them, and they are not cheap! The discussion around Fortibone is also exaggerated, as the one research study compared it with a placebo and not another collagen and was funded by the company producing it. I wonder whether any product or advice that costs a ridiculous amount of money is worth it. My parents both lived to 97, and I don’t recall them using any special powders or supplements or exercise routines, or vibrating plates. They may have eaten prunes periodically. But, that being said……just in case…..and since I’ve been warned repeatedly about my bone fragility, even though I have not yet fractured, I add a bit of collagen to my coffee or oatmeal, every once in awhile, hoping it might make a difference and that it won’t do any harm. You are right. Clear as mud and exhausting!

@glojo The reason your parents lived a long life is because of the quality of food they ate. Corporations, on the quest for greater profits, grow and process animal and produce in infant states, steers at 18 to 24 months, produce is picked green and then exposed to ethaline or xyline gas to turn it the appropriate color. The fruit remains firm. Less is lost in shipping. This creates a mineral and protein deficiency. All the collagen on the market is still processed from the same animals except one and it won't be on the market for another month: Rejuvenation Guaranteed. Com. The sourced animals are older, free range, wild caught, organic. Their protein is hydrolyzed for bioavalability and mixed at concentrations that corporations won't touch because that have boards to answer to. For instance collagen 10 is expensive so most collagen companies use no more than 1 to 3 percent. RG also adds a true bioflavinoide not an ascorbic acid which is a synthesised vitamin C. Your body knows the difference. This product guarantees results in 90 days or your money back. How do I know about this? I was in the clinical study. I feel better now than when I was in my late thirties. I workout and I have the body and skin of a much younger man. Their website will be up in a week or so. This is the future of medicine. Give your body "Nutritional restoration" and the body will do what it evolved doing, heal itself.

I’m perplexed as well.
Used NativePath fir nearly a year. I upped other supplements, exercise, less sugar..and Dexa was worse. No fractures known. Age 75 years
I plan on trying AlgaeCals package including strontium but not for a few more months.
I’m Getting a REMs Ultrasound scan for information on my Bone Quality, on October 6th then need to decide what direction to go.
Confused with minerals and other vitamins added in some of the powders and pills. What’s necessary what isn’t.

@eileenvan
What sweetener do you use? Sugars eat away at bones.
I have used honey, date syrup, which are high in sugar.
Stevia is ok but I don’t like taste. Others are not healthy.
I’m using xylitol packets now.

@pat9892 make sure that your collagen is third party c
tested like NSF is a third party tester.

@jozer I tried collagen well-researched supplements for an entire year, and saw no difference in skin, hair or nails. I do not have osteoporosis or even osteopenia, but have a strong family history of it, so I hoped it might help there too. My DEXA at the end of that year showed no change from 2 years prior, so probably no help there either.

As your primary told you, these supplements are unregulated, so we can only hope they contain what is promised (and nothing more). After a year of no particular benefit, I decided it was a failed experiment and quit.

@sueinmn I'm surprised you saw no difference in your nails, and even your hair. I take Osteonaturals-Fortibone, every other day. My nails grow so fast and I think my grey hair is more abundant. Were you taking it regularly?

Question for original poster: what did you decide to do about taking collagen?

I started Osteonaturals collegen last Sept and saw a noticeable difference in skin resilience within a couple of months. Since then I have not noticed anything else.

I am not due for a DEXA until next year.....presently on a drug holiday since last April, after ending Fosomax as the follow-on for Prolia. Trying to convince my new PCP to order CTX and P1NP and have next appointment in a couple of weeks.
