Collagen and Skin Well being

As we age, our manufacturing of collagen declines and impacts the structural integrity of our collagen community in our pores and skin. This ends in sagging of the pores and skin, wrinkles and aesthetic results of getting old. Nonetheless, the excellent news is that the analysis does appear to point that collagen dietary supplements could tighten pores and skin and assist to delay pores and skin getting old.

For instance, one 2015 research discovered that oral collagen supplementation elevated pores and skin hydration and density by bettering each amount and high quality of the collagen community. Equally, one other 2015 randomized management trial seemed intently on the results of collagen on pores and skin elasticity, hydration and wrinkles and located that individuals skilled a big discount within the depth of wrinkles. Individuals additionally skilled a 14% improve in water content material within the pores and skin, and improved pores and skin elasticity.

As well as, a latest 2020 systematic evaluation discovered that every one research reported helpful results of collagen supplementation on pores and skin getting old in each wholesome and unhealthy topics.

Alternatively, a latest 2019 evaluation discovered that the few research it evaluated discovered solely modest advantages to utilizing collagen complement. The authors steered that whereas preliminary findings are thrilling, there are plenty of limitations to the analysis. For instance, the research used totally different collagen manufactures, various doses, and confounding lively elements comparable to nutritional vitamins and minerals, all of which can influence findings. Participant traits have been additionally combined by way of geographical location, age, intercourse, and thus these variables influence our means to generalize the outcomes.

With that stated, collagen supplementation could assist to enhance pores and skin well being nonetheless it additionally extremely is determined by the kind of complement used and the way it’s made.

Collagen for Joint Ache

Collagen is considerable in our tendons and ligaments. Nonetheless, as we age and produce much less collagen within the physique, it will increase the danger for joint issues comparable to osteoarthritis (OA).

An early 2006 evaluation of the literature discovered that collagen dietary supplements considerably elevated collagen synthesis, leading to enhancements in OA ache and joint perform. A newer evaluation from 2020 analyzing 41 additionally research discovered vital advantages for OA signs and cartilage therapeutic. Equally, one other 2019 meta-analysis of randomized placebo-controlled trials discovered that collagen is efficient in bettering OA signs.

Whereas present preliminary analysis has been total constructive on the consequences of collagen supplementation for joint reduction, these research are usually not with out limitations. Specifically, many scientific research have been small scaled, short-term and in some instances, not even in people.

Usually talking, the physique of analysis we do have means that collagen dietary supplements could also be an efficient remedy for some individuals with joint issues and joint ache, however we want extra analysis to suggest it throughout the board.

Collagen for Bone Well being

Osteoporosis (OP) is a illness of the skeletal system characterised by bone mass loss, decreased skeletal construction and elevated threat of fractures. Growing older is one contributing issue to OP that we are able to’t precisely forestall, but it surely’s been proposed that insufficient collagen earlier on in life could play a job.

Sadly, the present analysis on collagen and bone metabolism in people is restricted. Nonetheless, there’s a rising physique of proof that collagen could assist assist calcium absorption, bone density and bone formation.

For instance, one 2018 randomized management research offered individuals with 5 grams of collagen per day which resulted in a big improve in bone density within the backbone and neck. Alternatively, one 2000 research checked out populations all through the USA, UK, and Germany discovered no vital variations in reported ache enchancment from collagen, however another symptom enhancements within the German group and individuals with extreme OP.

So how a lot do it’s essential take to see a profit? Whereas numerous research used totally different dosages, a 2016 evaluation of the literature really helpful a dosage of 12 g of collagen to encourage a few of these bone constructing advantages.

I do know it’s tempting to focus all our consideration on one nutrient alone however we now have to verify we now have an total nutritious diet.

Since our our bodies are capable of make collagen from breaking down protein, we don’t really must devour collagen particular dietary supplements in case you’re getting a variety of collagen within the weight-reduction plan already. For instance, you possibly can derive collagen from bone broth, beef, hen, fish, egg whites and dairy.

This contains meals comparable to soy merchandise, black and kidney beans, pumpkin, squash, sunflower and chia seeds, pistachios, peanuts and cashews.


It’s essential to take into account that dietary supplements are usually not extremely regulated. As talked about, some collagen dietary supplements add different elements to the product, comparable to nutritional vitamins, minerals and hyaluronic acid, and the mix of all these elements are usually not but nicely understood. Whereas the preliminary research appear promising and secure, there’s nonetheless an absence of large-scale randomized management trials and it’s also nonetheless unclear what the optimum dose is.

To not point out, some collagen dietary supplements value a reasonably penny.

If you’re inquisitive about attempting a collagen complement, at all times communicate to your physician beforehand and ensure you select a 3rd get together examined (e.g., product.
