Marine collagen is all the rage in anti-aging. What does that mean for fish? | Newz9

It might come as a scoop of white powder so as to add to a latte or smoothie, promising to assist achy joints and sagging pores and skin.

Or, as an ingredient in face masks and moisturizers, claiming to supply a youthful glow.

It’s marine collagen, a buzzword in magnificence and complement circles, usually derived from fish pores and skin, scales and bones, or different animals like sponges and sea cucumbers, relying on the product. 

The international market for marine collagen is already estimated at greater than $1 billion US and rising, pushed by demand to feel and appear youthful.

It’s promoted as an alternative to conventional sources of collagen dietary supplements, derived from land animals like cows and pigs, which some keep away from for spiritual or different causes.

Many marine collagen merchandise additionally market themselves as pure or eco-friendly, that includes photos of waves and fish and references to “cold, clean” ocean waters.

But with overfishing and local weather change already threatening international ocean wildlife, is this a sustainable place to show for anti-aging hope?

It relies upon, in response to these watching this emerging conservation issue, on the place the collagen is coming from — one thing that may not be clear at all while you choose up the product.

“With these marine collagen products, shoppers are buying a black box of marine ingredients,” mentioned Kelly Roebuck, sustainable seafood campaigner with the Canadian marine conservation group Living Oceans Society, in an e mail to Newz9.

Where collagen comes from

Our our bodies naturally make collagen, which supplies elasticity and power to our pores and skin, tendons, bones and different tissues. We make much less as we age.

But it is broadly discovered in the animal kingdom — even in the 68-million-year-old bone of a T. rex — so individuals have turned to collagen dietary supplements derived from different creatures.

Health Canada licenses greater than 2,000 pure well being merchandise containing hydrolyzed collagen as a medicinal ingredient, and greater than 1,000 with collagen from marine sources. 

Bovine collagen, from cows, has led that trade. But final 12 months, an investigation by the Bureau of Investigative Journalism, The Guardian and others linked cattle ranches producing collagen, leather-based and beef to tropical rainforest loss in the Brazilian Amazon.

The investigation traced the collagen provide chain to main corporations, together with the Nestle-owned model Vital Proteins promoted by Jennifer Aniston. (Nestle has mentioned it is taking steps to make sure merchandise are deforestation-free by 2025.)

Enter marine collagen, which was already being hailed by researchers as abundant and sustainable, with lower risk of disease transfer than collagen from mammals, and with chemical variations that might make it easier to absorb.

“It’s going boom,” mentioned Azizur Rahman, director of the University of Toronto’s Centre for Climate Change Research, who lately published a scientific review of marine collagen’s results on pores and skin growing old and heads a spin-off firm researching and growing marine collagen merchandise.

“Over the past decade or so, there has been a remarkable rise in market demand for marine-based cosmetics especially, driven by growing consumer interest in natural and sustainable ingredients.”

Another demand on fish

But sustainability is removed from assured relating to a brand new demand on marine creatures.

More than a third of the world’s fish stocks are overfished — harvested at ranges that cannot be biologically sustained — and that quantity is rising, in response to the newest international report from the UN’s Food and Aquaculture Organization. 

Most of the relaxation are additionally maxed out — labeled as fished to their biologically sustainable most.

“If you look at global seafood production from the oceans, particularly from captured fisheries, it peaks in the 1990s,” mentioned William Cheung, director of the Institute for Oceans and Fisheries at the University of B.C. in Vancouver.

“What it means is we are not able to produce more fish, even though we know that there are increasing demands for seafood.”

While Cheung is not conscious of any analysis particularly on marine collagen impacts, he says any new draw on the ocean needs to be thought of in that context — with climate change further threatening marine life and a rising international inhabitants depending on seafood, particularly in growing and low-income nations.

Canadian scientists have additionally raised issues about calls for for different dietary dietary supplements from fish, like shark liver oil and omega-3 fatty acids.

A Nature Ecology & Evolution paper in 2022 flagged marine collagen as an rising concern in ocean biodiversity, noting it could possibly be a menace to species like sharks or sponges. 

But the paper notes it is also a possibility for sustainable useful resource use — if it got here from pores and skin, bone and trims from the fish-processing trade that may in any other case go to waste.

Where is your marine collagen from? 

The tough half is marine collagen merchandise might not say what they’re fabricated from.

Some do promote the supply. For instance, Nova Scotia firm Landish says its marine collagen is from wild cod, haddock and pollock caught in the North Atlantic to make fish fillets. According to the firm, they use “byproducts only,” particularly the skin and scales. 

Toronto firm Genuine Health says its marine collagen is “upcycled” from the identical species caught in the “deep, cold seas of the North Atlantic.” (Neither firm replied to a Newz9 request for extra particulars.)

Nippi Collagen, a serious participant in the trade primarily based in Burnaby, B.C., informed Newz9 in an announcement it makes use of pores and skin and scale byproducts of the seafood trade, and the supply varies by grade. Lower grades are from farmed fish sourced globally, together with from Thailand and Indonesia; its premium grade is from wild-caught fish scales. (Further questions on fish species weren’t answered.)

But many merchandise don’t have any data on what animal was used, if it was wild or farmed, or what a part of the world it grew in.

“Like any fishery or aquaculture product, there can be sustainable or unsustainable sources,” mentioned Roebuck of Living Oceans.

“It is impossible for consumers to know what species is being utilized and whether they are contributing to overfishing, marine degradation or even illegal activities.”

Consumers can flip to eco-labels to assist keep away from that threat.

For instance, the Marine Stewardship Council’s (MSC) blue eco-label means the wild fish or seafood comes from fisheries that have been independently assessed and attain a set of sustainability requirements. (MSC’s customary has faced criticism from conservation groups for not being robust sufficient, and is being revised.) 

Kurtis Hayne, program director for MSC in Canada, says merchandise with the label are additionally audited for traceability — one thing that’s usually a problem in international fisheries.

“So anything with that blue MSC eco-label is a way of signalling that it’s from a sustainable fishery, and … there’s assurance, strong assurance that it’s coming from a certified fishery and not mixed up along the way.” 

In 2020, there have been no marine collagen merchandise with the MSC eco-label, but it surely’s been “growing quickly,” mentioned Hayne, with 37 globally as of final 12 months, primarily from MSC-certified Atlantic cod. 

The query of byproducts

While utilizing byproducts to make marine collagen does appear to have a decrease impression, it might nonetheless have penalties.

For instance, critics have argued that bovine collagen and leather-based, that are byproducts of beef, really assist the backside line of cattle manufacturing linked to deforestation, and thus encourage it.

On the flip aspect, Hayne mentioned that when a fishery has invested cash to grow to be extra sustainable, making earnings from what have been byproducts can encourage additional enhancements. 

“From our perspective, it allows us to reduce waste, but it also allows fisheries to extract more value out of this … precious wild resource,” mentioned Hayne.

Cheung calls the industrial processes that discard a lot of the fish “quite wasteful,” and notes that globally, many cultures depend upon the entire fish for meals.

“I grew up in the Chinese culture, from Hong Kong. So we eat almost every part of the fish,” he mentioned.

“We use the whole fish to make soup because I think with the fish bones that the fish soup is really rich and tasty and that actually provides a lot of nutrients.”

He hopes the rising demand for marine sources like collagen might be coupled with greater discussions about trade-offs, fairness and meals safety. 

“We need to use the available resources wisely and manage them wisely as well.”
