What Does Collagen Do and Why Is It Beneficial

Many people take daily collagen supplements or mix collagen powder into their coffee, tea, or smoothies in an effort to promote the health of their skin, joints, and hair.

The majority of people are unaware of what collagen is and what it accomplishes in the body, despite the surge in the use of collagen supplements and other collagen products.

Everything you need to know about collagen, including its definition, functions inside the body, and value of collagen supplements, is covered in this article.

Why is collagen vital and what does it do?

A class of protein is collagen. In actuality, it is the structural protein that is most prevalent in mammals. Proteins that make up the framework or structure of your cells and tissues are known as structural proteins.

There are 28 varieties of collagen that are now recognized, with type I collagen making up 90% of the collagen in the human body.

Glycine, proline, and hydroxyproline are the three amino acids that make up the majority of collagen. The triple-helix structure of collagen is made up of these amino acids, which are organized into three strands.

Connective tissue, skin, tendons, bones, and cartilage all contain collagen. It supports tissues structurally and is crucial for several biological functions, including:

  • tissue repair
  • immune response
  • mobile communication
  • cellular migration, an activity required for tissue upkeep

Collagen is created and maintained by fibroblasts, which are connective tissue cells. Collagen fragmentation, reduced fibroblast activity, and slowed collagen production are all effects of aging.

Age-related symptoms like drooping skin and wrinkles are brought on by these changes as well as the loss of elastin, another important structural protein.

Uses of Collagen

Your body naturally makes collagen, which you can also get from food sources including fish and chicken skin and supplements.

For the treatment of aging symptoms including wrinkles, dehydration of the skin, and joint discomfort, oral and topical collagen treatments like supplements and face creams are well-liked.

Collagen is available to purchase in liquid, pill, and powder form.

It can be consumed as a supplement or added to hot and cold beverages, as well as foods like oatmeal, yogurt, and energy balls.

In the medical arena, collagen and collagen-based products are also used by healthcare professionals, notably in the treatment of burns, wounds, and diabetic ulcers.

What causes a loss of collagen?

Your body’s natural collagen production decreases with age. In addition, collagen breaks down and spreads more widely.

These alterations cause the typical aging symptoms, such as wrinkles and sagging, dry skin. Age also causes a deterioration in the integrity of the collagen found in the skeletal system, which affects bone strength.

While collagen deterioration and loss as you age are unavoidable, several dietary and lifestyle choices might hasten this process.

For instance, it is well known that smoking cigarettes degrades collagen, which results in skin aging, wrinkles, and loss of elasticity.

It has also been demonstrated that excessive drinking speeds up skin aging by decreasing collagen formation and harming skin repair processes.

Additionally, consuming a diet high in processed foods and added sugars can speed up the aging process by promoting the glycation process, which slows down collagen turnover and interferes with collagen’s capacity to interact with other proteins and cells in the body.

Wearing sunscreen and limiting excessive sun exposure can help prevent the early indications of skin aging since excessive sun exposure reduces collagen production.

Best sources of collagen in food

All animals contain collagen, which is mostly present in the skin and joints of an animal.

Here are a few examples of foods high in collagen:

animal bones, skin, and ligaments, including pig knuckles, chicken skin, and jellyfish. Products derived from animal parts, such as bone broth, include fish skin and jellyfish.
Given that collagen is made by your body from amino acids, you can encourage collagen formation by making sure you’re getting enough protein from foods like poultry, fish, beans, and eggs.

Your body need additional dietary elements for collagen synthesis and maintenance in addition to amino acids.

For instance, since vitamin C is required for the synthesis of collagen, low or inadequate vitamin C levels might affect collagen production.

Therefore, eating a lot of foods high in vitamin C can assist the healthy development of collagen. Try citrus fruits, peppers, greens, and berries, for instance.

Additionally, eating a diet rich in advantageous plant chemicals may enhance skin health by lowering inflammation and preventing collagen deterioration.

Does consuming collagen supplements have any advantages?

There may be some advantages to using collagen supplements, according to studies.
Possibly advantageous for skin
Supporting skin health is one of the most well-liked applications for collagen supplements. According to research, using collagen supplements may enhance the health and appearance of the skin in some ways.

In comparison to placebo treatments, consuming hydrolyzed collagen improved skin hydration, suppleness, and wrinkles in a review of 19 research with 1,125 participants (95% women) between the ages of 20 and 70.

A procedure known as hydrolysis is utilized to produce the typical type of collagen used in supplements: hydrolyzed collagen. The protein is divided into smaller bits during this process, making it simpler for the body to absorb.

Numerous studies have indicated that consuming collagen supplements may increase the moisture and flexibility of the skin as well as lessen wrinkle appearance.

Though many of these research were supported by businesses that produce collagen products, keep in mind that this could have influenced the study’s findings.

The collagen doses that have been found in trials to be useful for enhancing skin health range, although most studies have utilized 2.5–15 grams per day for 8 weeks or longer.

Possible advantages for bones

Collagen supplements might have some additional advantages aside from enhancing some areas of skin health and appearance.

One study examined how collagen supplements affected 102 postmenopausal individuals with low bone mineral density (BMD).

BMD in the spine and femur (a bone in the lower leg) significantly increased in those who took 5 grams of collagen peptides per day for a year as compared to those who received a placebo .

Taking 5 grams of collagen per day for a total of 4 years was linked to a gradual rise in BMD, according to a follow-up research involving 31 of these women.

The researchers discovered that over the follow-up period, the individuals’ BMD rose by 5.79-8.16% in the spine and by 1.23-4.21% in the femur.

These results imply that long-term collagen supplementation may aid in increasing bone mineral density in postmenopausal women who are more susceptible to osteopenia and osteoporosis.

Additionally, a review study found that participants’ osteoarthritis symptoms, such as stiffness, were lessened by taking oral collagen supplements.

Supplementing with collagen may provide other health advantages, such as enhancing body composition in some populations when paired with resistance training.

It’s crucial to remember that studies primarily looked at elderly women with low bone mineral density to see if ingesting collagen had any positive effects.

Are there any adverse effects to collagen supplements?

Supplements containing collagen have a strong safety record and are not linked to any negative side effects.

However, producers frequently mix collagen with additional substances in dietary supplements. Herbs and high vitamin concentrations included in supplements designed to improve the health of the skin, nails, and hair could be harmful to your health.

For instance, substances in nutritional supplements, including herbal extracts, may interact with regularly prescribed drugs, and some are unsafe for women who are pregnant or nursing.

Additionally, certain collagen-containing supplements may also have high quantities of minerals like biotin, which could affect testing in the lab for thyroid and heart function.

Additionally, certain collagen-containing supplements may also have high quantities of minerals like biotin, which could affect testing in the lab for thyroid and heart function.

If you consume high doses of these and other vitamins and minerals for an extended period of time, you may experience health problems.

Therefore, even while supplements that only include collagen are unlikely to have any adverse effects, it’s crucial to study labels and comprehend the possible risks of supplements that also contain other chemicals in addition to collagen.

Before beginning a supplement regimen, be sure to see a healthcare provider if you’re on any other medications, are pregnant, or are nursing.

Supplemental collagen versus protein

It’s crucial to remember that maintaining your body’s collagen levels and bone health does not require you to consume collagen or use collagen supplements.

In reality, by consuming adequate amounts of high-quality protein, vitamin D, calcium, vitamin C, and zinc in your diet, you can support your body’s ability to create collagen and maintain healthy collagen levels and bone structure.

For maintaining bone and muscle mass as you age, eating a balanced diet with a little more protein is particularly beneficial. In order to do this, experts advise taking more protein than 0.36 grams per pound (0.8 grams per kilogram) of body weight (30).

Combine this protein-rich diet with exercise, especially weightlifting and resistance training, to support this.

How to stop collagen loss

Although it is hard to completely stop the loss of collagen with age, the process can be slowed down.

As was already discussed, diet and other lifestyle choices can have a big impact on how much collagen your body produces.

Following a diet rich in ultra-processed foods and added sugar has a negative impact on collagen formation, as does smoking cigarettes and consuming large amounts of alcohol.

On the other hand, living a healthy lifestyle that includes eating a diet high in nutrients, quitting smoking, and drinking in moderation may prevent age-related changes in collagen and lessen aging symptoms like wrinkles.

It may be possible to support collagen maintenance and general skin health by avoiding or consuming fewer of some foods and beverages while consuming more of others.

For instance, a diet low in substances known as advanced glycation end products (AGEs) may support the health of the skin. Toxins called AGEs build up in the skin. They have the ability to deactivate the proteins needed for collagen repair and harden collagen.

According to more recent and earlier studies, foods high in AGEs include fried foods like french fries and fried chicken, processed meat products like hot dogs and bacon, roasted and grilled meats, and fried foods.

A diet rich in high-quality protein and plant foods, including as fruits and vegetables, which include elements that support and protect collagen, may also aid in preserving collagen storage and preventing collagen breakdown and loss.


The protein collagen is present in cartilage, skin, tendon, bone, and connective tissue.

In addition to aiding in vital body functions including tissue repair and cell signaling, it supports tissues structurally.

Your body naturally produces collagen, but you can also ingest it by taking supplements and eating specific foods. This could help your skin, bones, and other body parts by improving their health.

Collagen supplementation appears to be particularly beneficial for specific conditions and demographics, according to studies, including raising bone mineral density (BMD) in postmenopausal women with low BMD.

A balanced diet that includes enough amounts of zinc, vitamin D, vitamin C, and protein provides a healthy and less expensive alternative to supplements. You can lessen collagen and bone loss as you age by doing this together with regular exercise.

Even though age-related collagen loss is inevitable, maintaining a healthy lifestyle can help stave off its effects, slow the aging process, and improve general wellbeing.
