Collagen refers to a group of related proteins in the human body. The proteins make up a large portion of different connective tissue throughout the body, including the:

  • skin
  • joints
  • cartilage
  • tendons

Collagen supplements usually come as oral pills, tablets, powders, or capsules. Liquid varieties are also available.

There are 28 types of collagen, but supplements will typically include four common varieties:

  • Type I: This is the most common type, which is present in all connective tissues. It is flexible and provides resistance to stretching, force, and tension.
  • Type II: This type is in the joints and discs between the vertebrae. It helps to provide pressure resistance.
  • Type III: This type is a main component of the reticular fibers in the skin and blood vessels. It is present in high amounts during wound healing.
  • Type IV: This type of collagen is a mesh that forms part of the structure of the kidneys, inner ear, and the lens of the eyes.

When a person takes collagen supplements orally, they may promote health and healing in the skin and joint health.

Skin health

In a 2019 study, researchers found that taking a particular brand of collagen supplement helped improve skin elasticity, hydration, and density. It also aided in smoothing rough patches of skin. They also noted that people generally tolerated the supplements well.

It must be noted that the study included fewer than 80 participants who were all female and used only Elasten supplements. The research was also funded by the same company that manufactures Elasten. As a result, the findings may not be applicable across all collagen supplements or people.

This collagen supplement also included other ingredients, such as acerola fruit extract, vitamin C, zinc, vitamin E, and biotin. The placebo did not contain these nutrients. The additional ingredients in the collagen supplements may have led to the benefits that scientists discovered in the study rather than the collagen alone being responsible.

Another 2019 review found similar results across multiple studies.

Joint health

Collagen supplements may help keep the joints healthy and improve their health over time.

A recent study published in 2019 showed similar results. Scientists found that regular use of collagen supplements helped improve symptoms of osteoarthritis.

Although the Food and Drug Administration (FDA) plays a role in supplement safety and manufacturing claims, it does not directly regulate the quality or content of supplements.

With this in mind, a person should look for products with third-party testing. Companies, such as U.S. Pharmacopeia and NSF International, provide purity and quality control testing for different supplement brands.

People can also explore online reviews of the company and the products it offers. However, these reviews are anecdotal, meaning they only apply to some people.

Before ordering any supplement, an individual should consult a doctor to ensure it will not interfere with their current medications or any underlying health conditions.

Vegan collagen

Most collagen comes from bovine hide, so it is unsuitable for people following a vegetarian or vegan lifestyle. While some vegetarian collagen supplements are available, those following a vegan lifestyle may want to check that the supplements do not use animal products.

Most of the supplements people think are vegan collagen are actually collagen boosters or collagen builders. They do not contain any collagen. Instead, they have nutrients that may support collagen synthesis, so they may not produce the same effects as supplements in the studies.

Furthermore, scientists have discovered a way to produce vegan collagen using bacteria and the yeast strain Pichia pastoris, though there are currently no commercially available products on the market.

Side effects of collagen supplements are not common. However, anyone with sensitivities or allergies should check the product labeling carefully.

Some additional ingredients can include:

  • eggs
  • gelatin
  • shellfish
  • dairy

If a person consumes something that they are sensitive to it can cause digestive side effects, such as bloating.

It is best to consult a physician before taking a collagen supplement. It is also important to note that supplements are not substitutes for a balanced and nutritious diet.

Collagen may not be the right or best choice for everyone. It also should not replace treatment or recommendations from a doctor or other qualified healthcare professional.

Alternatives for collagen may depend on a person’s reasons for its use. An individual wishing to improve their skin care may want to look at moisturizing creams and other products that promote skin health.

Those looking to promote joint health may want to speak with a doctor about their concerns, as they may find other supplements that support the joints.

Learn how to boost collagen levels in the skin.

In a 2019 study, researchers identified several common sources of collagen in the American diet. They include:

  • beef
  • bone broth
  • fish
  • chicken
  • pork
  • prepared meats

A 2018 systematic review suggests that vitamin C increases the production of collagen in the body.

Learn about how to get collagen from food.

Below are answers to common questions about collagen supplements.

Do collagen supplements really work?

A 2019 literature review that included 11 studies involving 805 people found that supplemental collagen helps improve skin elasticity, hydration, and collagen density. It may also be useful for wound healing.

A 2021 literature review also found collagen supplements beneficial for joint health.

Confirming these benefits and exploring the full effects requires further research.

How long does it take for collagen supplements to work?

Studies show that people can see results from collagen supplements in 8 weeks, although it may take longer.

Does collagen make a person gain weight?

While the evidence is limited, weight gain is not a known effect of collagen supplements.

A 2019 study found that people who combine collagen supplementation with resistance training may develop more muscle mass than those who exercise without supplementation. Gaining lean muscle can make a person heavier.

How do I choose the best collagen supplement?

People may consider the following before buying collagen supplements:

  • the form
  • the price
  • ingredients
  • testing processes
  • how and when to use

People should prioritize products that have gone through third-party testing ensuring the product does not have any unlisted or unsafe ingredients.

What is the most effective collagen to take?

Collagen can be effective for different health concerns, but it also depends on the type of product a person chooses. For example, a 2021 study found that using hydrolyzed collagen for 90 days can help reduce the appearance of wrinkles and improve the skin’s elasticity.

Another study reports that collagen supplements may suit people looking to improve skin elasticity.

What is the best and healthiest collagen?

People looking for healthy collagen supplements may look for a product free of hormones and artificial sweeteners. Those who follow a gluten-free diet may also choose supplements without this ingredient.

People can also consider collagen supplements that offer a range of essential amino acids and or use collagen peptides, as these may be easier for the body to digest.

Collagen supplements may help promote skin and joint health. They may also offer other health effects, but there is not enough evidence that supports their use.

These products typically come in capsule or powdered forms and usually contain collagen from bovine or other animal or fish sources. Vegetarian and vegan alternatives are available as collagen boosters or builders. However, these do not contain collagen — their ingredients may help support collagen production.

Before starting any new supplement, a person should talk with a doctor as they may recommend alternative solutions to help address their health concerns.
