Luis Echeverri Urrea/iStockphoto/Getty Pictures The explorer Ponce de Leon famously went to Florida looking for the fountain of youth. However if you happen to hearken to social media influencers, he ought to most likely have headed to the complement aisle to choose up some collagen.

"I am in my 40s and if I shave, I appear like I am in my mid-20s," a Tiktok creator who goes by Store By Jake claims in a single paid promotion. "Individuals ask me on a regular basis, what do you do to your pores and skin? I take collagen," he says.

Claims in regards to the well being and wonder advantages of collagen dietary supplements are commonplace today, particularly on-line. However does the proof again the hype?

The declare Collagen dietary supplements can promote more healthy pores and skin, hair and nails, and stronger joints.

The speculation Collagen is probably the most plentiful protein within the physique. It is present in pores and skin, hair, nails, tendons, ligaments, cartilage, and bones. It helps preserve our pores and skin's elasticity and quantity. It is a structural protein, so it provides energy and integrity to our tissues and retains joints robust, amongst different issues. However beginning in our 20s the quantity and high quality of the collagen our our bodies produce declines.

Components like UV radiation, smoking, and publicity to environmental pollution can pace up that decline. However it should occur with age regardless. Which is why plenty of folks flip to collagen dietary supplements.

Collagen dietary supplements typically are available two foremost varieties. Hydrolyzed collagen peptides are principally collagen that is been damaged down into smaller chains of amino acids to make them simpler to soak up. They're derived from animal sources, comparable to fish, cattle, pigs or rooster. That is usually what's utilized in dietary supplements aimed toward bettering pores and skin and hair, in addition to joint well being.

"The speculation is that if you happen to ingest [a collagen supplement,] it goes by means of the GI tract and will get absorbed after which it theoretically goes to locations to assist or improve collagen manufacturing," says Dr. Lauren Taglia, a board-certified dermatologist with Northwestern Drugs in Naperville, Ailing.

The second foremost type of complement is undenatured, or native, sort II collagen, which hasn't been damaged down. It is derived from chickens. A lot of the collagen present in cartilage is sort II. These sorts of dietary supplements are thought to advertise joint well being by triggering the immune system to supply chemical messengers that tamp down irritation.

So what does the analysis say?

The proof Let's begin with pores and skin.

In terms of pores and skin well being, there are research that recommend collagen dietary supplements work.

"There have been randomized managed trials which have proven that after 8 to 12 weeks of collagen supplementation, issues like depth of wrinkles, pores and skin elasticity, dermal thickness appear to be improved," says Dr. Maryanne Makredes Senna, an assistant professor of dermatology at Harvard Medical College.

One meta-analysis of 19 research printed in 2021 discovered that, in contrast with a placebo, folks taking collagen dietary supplements had higher pores and skin hydration, elasticity and enhancements in wrinkles.

A second meta-analysis was printed this yr. It checked out 23 randomized managed trials with greater than 1,400 sufferers who took collagen dietary supplements for pores and skin points, and it additionally discovered vital enhancements in those self same areas after 90 days.

However Senna says these findings got here with a giant caveat: The research that discovered the largest enhancements have been lower-quality and have been funded by the complement trade, she says.

"Excessive-quality research and research not funded by trade didn't present a major affiliation price," Senna says.

On condition that, the state of the proof on the subject of collagen dietary supplements for pores and skin is blended at greatest, says dermatologist Lauren Taglia. "As physician-scientists, we might like to see research accomplished on a big scale and accomplished independently," she says.

It is a related story on the subject of collagen dietary supplements for joint well being. Research have proven advantages — comparable to in lowering ache from osteoarthritis.

However once more, a lot of the analysis is trade funded, so it may be exhausting to disentangle potential bias, says Dr. David Felson, an osteoarthritis researcher and professor at Boston College.

One systematic evaluate discovered that a lot of the research of collagen dietary supplements for rheumatoid arthritis and osteoarthritis have been too low high quality to find out whether or not they actually helped. Some research included in that evaluate reported adversarial results, comparable to an exacerbation of signs.

"With respect to collagen, I do not know what the best reply is," Felson says. It might probably assist, however "there aren't any massive scale research right here and there have to be," he says.

The underside line If it is more healthy pores and skin you are after, collagen dietary supplements "may very well be useful, however there's not a ton of robust proof to assist them at this level," Taglia says.

Your greatest wager is to concentrate on issues that do have strong proof behind them, says Dr. Maya Jonas, an assistant professor of dermatology on the Ohio State College. That features carrying sunscreen and different solar safety and utilizing vitamin A-based merchandise like retinol, which have been clinically confirmed to stimulate collagen manufacturing. Preserving your pores and skin moisturized can be vital.

Life-style elements matter too, Jonas says. She recommends a eating regimen wealthy in fruit and veggies, which offer antioxidants like Vitamin C, and nuts and seeds, that are good sources of zinc and copper and assist assist collagen manufacturing.

"We all the time discuss eating regimen, ensuring sufferers are consuming a wholesome Mediterranean eating regimen that is well-balanced, avoiding alcohol, not smoking and avoiding secondhand smoke," Jonas says.

And get loads of sleep and train, provides Senna. Poor sleep and stress can take a toll on pores and skin, whereas train can enhance blood circulation to the pores and skin and will assist counteract the lack of elasticity and dermal thickness that comes with getting old.

That is not simply good for pores and skin, however general well being, too.
