By Dr. Mercola
Boring, wrinkled, sagging pores and skin and dry, brittle hair and nails — all of those are indicators of growing older, which largely could be attributed to the lack of collagen that happens naturally with age. Collagen is the most typical and plentiful of your physique’s proteins, comprising about 25 p.c of the overall protein in your physique, and as much as 80 p.c of your pores and skin, when it comes to dry weight.1
It’s discovered particularly within the connective tissues all through your physique, out of your muscular tissues, bones and tendons to your blood vessels and digestive system. As a compound of important amino acids, there’s just one option to get collagen; your physique can’t produce it, so you should get hold of it by way of your weight loss program. Most individuals, nonetheless, will merely attain for a collagen complement slightly than boiling down rooster ft or beef bones for a do-it-yourself collagen-rich broth.
However what are you actually getting in these dietary supplements? Latest laboratory testing stirred up controversy with well-liked collagen and bone broth merchandise outcomes revealing potential contaminants — together with antibiotics, prescription drug metabolites, parabens, steroids and pesticides.
Troublesome Contaminants Present in Many Nonorganic Collagen Merchandise
The collagen merchandise in query have been chosen based mostly on their recognition and gross sales rating on Amazon.com, and all have been nonorganic. The outcomes point out that if you’re consuming bone broth or collagen merchandise that are usually not natural you’re doubtless getting CAFO (concentrated animal feeding operations) byproducts. As reported by the Shopper Wellness Heart (CWC):2
“The nonprofit Shopper Wellness Heart has accomplished testing of eight well-liked bone broth and bone broth protein merchandise to find out the attainable presence of chemical pesticides, prescription drugs, industrial chemical compounds, toxicological chemical compounds and meals additive chemical compounds. No firms paid the CWC to be included or excluded from these exams. All merchandise have been bought from Amazon.com within the 12 months 2017.
Lot numbers of every product examined are included within the full outcomes. Nobody concerned on this testing has any monetary stake within the success or failure of any bone broth product … Chemical analytes have been confirmed utilizing 5 totally different scientific evaluation strategies. These strategies, encompassed in LC-MS-TOF evaluation, embody correct mass, retention time, isotopic ratios, isotopic spacing and ion fragmentation ‘fingerprint’ evaluation.” three
Different chemical compounds claimed to be present in a few of these merchandise embody:four
- Butylparaben, an endocrine-disrupting chemical related to lowered testosterone ranges5 and irregular form, measurement and motility of sperm6
- Cyclandelate, a vasodilator drug
- Netilmicin, an antibiotic
Nonorganic Collagen and Bone Broth Merchandise Are Seemingly CAFO-Derived
So, what do these outcomes imply? In a nutshell, if a collagen or bone broth protein product shouldn’t be licensed natural, it is extremely doubtless the first substances are sourced from animals raised in CAFOs. If you don’t devour manufacturing facility farmed/CAFO meats, you doubtless shouldn’t be consuming CAFO collagen and bone broth merchandise.
Manufacturing facility farmed animal merchandise are problematic for a lot of causes, reminiscent of accelerating antibiotic resistance, poor circumstances for the animals, and as a result of the farms contribute to extreme environmental air pollution. Because the information unfold of those findings, CWC up to date its press launch with the following disclaimer:
“After reviewing client suggestions concerning the lab exams, Shopper Wellness Heart has realized that many individuals are misinterpreting these outcomes, and a few are taking them out of context … [T]he chemical compounds initially detected weren’t substances nor overwhelming indicators that will point out any kind of acute well being threat or illegality …
[A]t no level did the CWC assert that the merchandise examined have been acutely harmful or working afoul of FDA rules. The FDA permits astonishing ranges of many chemical compounds in non-organic merchandise, and that is ceaselessly mirrored and affirmed in scientific lab testing outcomes.”
CAFO-derived collagen and bone meal or broth might not be acutely poisonous, however buying meals merchandise from manufacturing facility farms is a problematic follow. I like to recommend consuming largely natural meals, as every and each supply will add to your general poisonous load. Different research have proven CAFO animal bones and hides may also be a supply of heavy metals reminiscent of lead,7 which is one other potential concern when shopping for nonorganic animal merchandise.
Varieties of Collagen
Whereas 28 several types of collagen have been scientifically recognized, most dietary supplements will include a number of of simply three of those, that are identified merely as:eight,9,10
- Kind I — collagen present in pores and skin/disguise, tendon, scales and bones of cows, pigs, rooster and fish
- Kind II — shaped in cartilage and sometimes derived from poultry
- Kind III — fibrous protein present in bone, tendon, cartilage and connective tissues of cows, pigs, rooster and fish
Varieties I, II and III comprise 90 p.c of the collagen in your physique.11 When speaking about collagen, you additionally have to know the distinction between unhydrolyzed (undenatured) or hydrolyzed (denatured) collagen. Of their pure, hydrolyzed state, collagen molecules are poorly absorbed resulting from their giant measurement.
Hydrolyzation refers to a processing method that breaks the molecules down into smaller fragments, thereby enhancing intestinal absorption. Because of this, most collagen merchandise, whether or not topical or ingestible, are hydrolyzed.
Collagen Versus Gelatin
Gelatin is a staple in Paleo-based diets. The distinction between collagen and gelatin is that collagen is the uncooked materials, and gelatin is what you get once you prepare dinner the collagen.12 When you’ve ever made do-it-yourself bone broth, you may discover it kinds a layer of gelatin on the prime when it cools. That is the collagen from the bones and cartilage that has was gelatin, a formidable superfood.
In actual fact, making your personal bone broth from the bones of natural grass fed or pastured animals is among the finest (and most cheap) methods to get wholesome collagen into your weight loss program. Hydrolyzed collagen (additionally referred to as collagen hydrolysate) requires extra intensive processing and can’t be produced at dwelling. Hydrolyzed collagen and gelatin are related however not equivalent.
Whereas each merchandise include the identical amino acids, they’ve totally different chemical properties and subsequently differ in how you should use them. Each gelatin and hydrolyzed collagen have gut-healing properties, aiding digestion and lowering irritation, though hydrolyzed collagen tends to be extra simply digested.
Since hydrolyzed collagen has been damaged down into smaller parts, it may possibly dissolve in each cold and warm liquids whereas gelatin will solely dissolve in sizzling liquid. And, since hydrolyzed collagen is not going to gel, it can’t be used as an alternative to gelatin in dishes like puddings and sauces.
On a facet observe, collagen shouldn’t be solely taken internally to enhance hair, pores and skin and nails. It is also a key part of wound therapeutic and is utilized in wound dressings. Collagen dressing containing gelatin has been proven to be notably priceless within the remedy of continual wounds, as its biochemistry enhances signaling to cells liable for creating granulation tissue.13
When Shopping for Poultry-Primarily based Collagen, Go for Natural
The take-home message right here is that if you are going to use a poultry-based collagen complement, be certain that it is licensed natural by the U.S. Division of Agriculture (USDA),14 as that is the one natural label that relates on to meals.
Whereas natural requirements are imperfect, producers of natural merchandise bearing the USDA seal have to fulfill the strictest requirements of any of the presently out there natural labels, so it is nonetheless your finest assurance of natural high quality. Bear in mind merchandise can include various ranges of natural substances:
- Merchandise labeled “100% Natural” should include solely organically produced substances and can’t include preservatives or taste enhancing chemical compounds, or traces of heavy metals or different contaminants in extra of tolerances set by the U.S. Meals and Drug Administration (FDA).15 Livestock additionally can’t be given development hormones
- Merchandise labeled “Licensed Natural” or merely “Natural” should include a minimum of 95 p.c natural substances
- The label “Made with Natural Substances” can include wherever between 70 to 95 p.c natural substances
To make sure you are truly getting your cash’s value, search for the “USDA Natural” label. The usage of the natural seal proven above is non-compulsory, however the label should clearly state “Natural.” The natural certification might not be excellent, however it’s sometimes the most effective reassurance you may get if you happen to have no idea the direct supply of your meals.
Watch out for manufacturers which have “natural” of their model identify however don’t truly bear the USDA label, or manufacturers that attempt to trick you with phrases that appear like “natural,” reminiscent of “organix” or related twists on the phrase. If it’s not clearly spelled out on the label, and spelled accurately, it’s not licensed natural.
For Bovine-Primarily based Merchandise, Search for Grass Fed Certification
If the product is derived from bovines (cows), you may wish to be certain that the product is licensed grass fed. Take into account that this is applicable not solely to collagen dietary supplements but additionally to gelatin, generally utilized in cooking and baking. On this case, the label you are searching for is the American Grassfed Certification label. The American Grassfed Affiliation’s emblem is the one one in a position to assure the animals:
- Have been fed a 100 p.c forage weight loss program
- Have by no means been confined in a feedlot
- Have by no means obtained antibiotics or hormones
- Have been born and raised on American household farms (a overwhelming majority of the grass fed meats bought in grocery shops are imported, and with out COOL labeling, there is no telling the place it got here from or what requirements have been adopted)
How Are Collagen Dietary supplements Made?
To perceive what you’re truly shopping for, it’s value figuring out how collagen or bone broth merchandise are literally made. Bone meal is basically a byproduct of typical livestock farming, with most of it coming from poultry operations. As soon as chickens are processed for his or her meat, the bone scraps are boiled in water to acquire bone broth. The liquid is strained to take away any remaining bone items after which dried right into a powder.
On account of this course of, most of the contaminants discovered within the bone of the animal will likely be current within the ultimate product, as evidenced by the featured lab testing. That is why the supply of the collagen is so vital.
When you begin with a contaminated product — chickens fed genetically engineered (GE) corn laden with pesticides, for instance, or animals that have obtained medication or different contaminated feed — the tip product will include traces of these contaminants as effectively. The most effective if not solely option to keep away from them is to begin with a pure supply, on this case organically-raised, pastured or grass fed animals, and make a collagen-rich soup at dwelling.
How Collagen Advantages Your Physique
As defined by Caroline Brochard-Garnier, communication supervisor for Rousselot, a producer of gelatin and collagen merchandise for the drug, meals and dietary markets:16
“When a collagen peptide preparation with optimized molecular weight and confirmed bioavailability is ingested, small collagen peptides are absorbed rapidly into the blood stream. The presence of those peptides in pores and skin tissue, stimulate pores and skin cells (fibroblasts) and activate a number of biochemical pathways which in flip results in a response which is extensively accepted:
Small collagen peptides are believed to behave as a false sign of the destruction of collagen within the physique, triggering the synthesis of latest collagen fibers, which in flip will increase pores and skin suppleness and reduces the formation of wrinkles. As well as, the synthesis of hyaluronic acid is stimulated which results in a rise in pores and skin hydration.”
There are Many Secure Methods to Increase Your Collagen
High quality is all the time an overriding concern when shopping for a complement, and collagen merchandise aren’t any totally different. Since they’re derived from animal components, the way in which these animals have been raised and fed is of paramount significance. So, when shopping for a collagen complement, ensure it’s “USDA Natural” and/or AGA grass fed licensed.
Many consultants additionally advocate growing consumption of collagen constructing blocks as effectively.18 This consists of vitamin C and anti inflammatory, antioxidant-rich leafy greens and berries. This fashion, your physique may have what it must protect and produce the collagen wanted.
