The Best Collagen Supplements of 2021

Last Updated February 6, 2021


If you are keen on starting skincare or already have a routine set, chances are you may have come across products that contain collagen. Being something that is actually naturally produced by our bodies – collagen makes up an astounding 80 percent of our skin – consuming it has been claimed to make our skin look dewy and fresh, among other benefits.

So what exactly is collagen and its actual benefits? What forms do they come in and which is best for you? Continue reading as we answer these questions and also highlight on the top rated collagen supplements in 2020!

What is Collagen?

Collagen is a highly abundant and important structural protein in the body. It helps to form connective tissue throughout the body, from skin to bones and muscles. Collagen and another protein named elastin work together to help keep the skin elastic.

As we age, the human body naturally produces less and less collagen. It also gradually loses its capability of replacing the collagen as fast as it had been broken down. Other factors including sun exposure, cigarette smoke and pollution can also quicken this process. According to board-certified dermatologist Dr. Whitney Bowe, as quoted in an article by The New York Times, we begin losing about one percent of our collagen each year starting in our 20s, meaning that our skin gets drier and less elastic.

This makes the concept of supplementing our collagen appealing from a dermatologic perspective.

What are the Benefits of Collagen?

We will highlight three likely health benefits of collagen as follows.

1. Skin Health

This is perhaps the main benefit you can gain and one of the leading reasons for consuming collagen supplements or applying collagen-rich products onto the skin in the first place. Essentially, collagen promotes better skin health by:

According to one study, women who had taken a supplement containing 2.5 to 5 grams of collagen for eight weeks were found to have experienced less skin dryness and greater skin elasticity, compared to a group of women who did not take the supplement during the same period of time.

In a separate study, it was found that women who drank a beverage mixed with a collagen supplement daily for 12 weeks had increased skin hydration and reduced wrinkle depth, compared to a control group.

2. Muscle and Bone Maintenance

Collagen can actually be found throughout your body.

The bones of the human skeleton is mostly made of collagen. It even helps maintain the integrity of cartilage, which is the rubber-like padding that protects the joints. Furthermore, between one to ten percent of muscle tissue is composed of collagen.

This is all because collagen is a highly necessary protein in giving the bones structure and keeping them strong, supporting the joints and ensuring the muscles stay strong and functioning properly.

For instance, in one study which had 27 frail men participating in an exercise program consume 15 grams of collagen daily for 12 weeks, they had gained significant muscle mass by the end of the program, compared to a control group. Researchers suggested that collagen may promote the synthesis of muscle proteins, such as creatine, and stimulate muscle growth post-exercise.

3. Heart Health

In addition to building the structure of bones, muscles and skin, collagen provides structure to your arteries, which are essentially the blood vessels that transport oxygenated blood away from the heart to the rest of the body. Without sufficient collagen production, the structure of arteries can become affected, making them weak and fragile. Narrowing of the arteries,may lead to atherosclerosis, a disease which, in turn, may lead to heart attack and stroke.

By the end of one study, which had 31 adults consume 16 grams of collagen daily for six months, it was found that the consumption of collagen supplements contributed a significant reduction in artery stiffness and an increase in levels of HDL “good” cholesterol, by an average of 6%.

Are There Different Types of Collagen?

Yes. There are at least 28 different types of collagen, but not all of them are created equal.

With many forms of collagen supplements on the market, and various brands touting the effectiveness of such supplements, it is important to look into and understand the different types of collagen protein. Based on the article by Humann, we will highlight on five types of collagen protein and the best sources in order to obtain each type.

Type I Collagen

Type I collagen fibers can be found in the skin, muscles, cartilage and blood vessels. This type of collagen is widely known for its anti-aging properties, as it is best in minimizing wrinkles and improving health and hydration.

The best sources to obtain Type 1 collagen are:

  • Fish or other seafood;
  • Egg whites;
  • Protein-rich foods, such as fish, beef, bone broth, etc.

Type II Collagen

This type of collagen is known for promoting joint health and can treat joint pain quite effectively. It has also been found that, out of the other collagen types consumed orally, Type II collagen is capable of surviving the digestive system intact more often.

The best sources to obtain Type II collagen are:

  • Bone broth;
  • Chicken collagen;
  • Protein-rich foods, such as chicken;
  • Multi-collagen protein powder.

Type III Collagen

Type III collagen is the second most prevalent collagen fiber after type I. It is commonly found in the muscles, as it is critical for building muscle fiber structure as well as organs and blood vessels, and there is evidence that having sufficient levels of this type of collagen can enhance exercise performance, even possibly build muscle mass and assist in weight loss. On the other hand, having insufficient levels of this collagen could lead to rupture of blood vessels and a specific type of aneurysm.

The best sources to obtain Type III collagen are:

  • Bovine collagen peptides;
  • Protein-rich foods;
  • Collagen protein powder.

Type IV Collagen

This type of collagen exists naturally in the layers of skin surrounding the muscles, organs and fat in our body. It assists in filtration in the kidneys, among other organs. Having sufficient levels of Type IV collagen ensures proper building of skin structure, wound healing and smooth digestion, while insufficient levels could lead to digestive disorders.

It is not common for Type IV collagen to be available in the form of supplements.

The best sources to obtain Type IV collagen are:

  • Egg whites;
  • Protein-rich foods.

Type V Collagen

Type V collagen can be found in the cornea of the eye and, therefore, deficiency of this collagen may lead to vision impairment and lower eye health. This type of collagen is also important for the structure of the placenta tissue, which is highly critical in the development of an embryo.

The best sources to obtain Type V collagen are:

  • Protein-rich foods;
  • Multi-collagen protein powder.
