What Is Collagen?
Collagen is a substance that makes up about 30% of the total protein in your body [1]. It mostly forms your skin, bones, muscles, ligaments, tendons, and other connective tissues. What’s more, collagen acts as a lining for your organs, blood vessels, and intestines.
It’s primarily made from glycine, hydroxyproline, and proline, 3 kinds of amino acids. These group together in a triple helix structure—along with zinc, manganese, vitamin C, and copper—to create collagen.
There are five main types of collagen:
Type 1: It accounts for around 90% of your body’s collagen, providing structure to your skin, bones, tendons, and ligaments [2].
Type 2: This is found in cartilage, which supports your joints.
Type 3: It’s usually part of the muscles, arteries, and organs.
Type 4: You can see this in the layers of your skin.
Type 5: This is found in your eye corneas, hair, skin, and the placenta tissue.
Collagen Benefits
Modern research reveals that collagen has many health benefits. Here are some perks you might experience if you consistently take the best collagen s͏upplement brands.
Skin Health
Collagen is a major part of your skin, which may strengthen it, keep it elastic, and hydrate it.
As you age, your body’s collagen production may drop, bringing about symptoms like dry skin, wrinkles, and even sagging skin.
Some studies have shown that taking oral or topical collagen supplements daily may help reduce dryness and wrinkles while improving skin appearance [3].
Joint Support
Collagen also helps your joints work properly by supporting cartilage, the rubbery tissue that protects joints and allows them to move freely [4].
As your collagen formation and production lessens with age, those joints are likely to become less flexible; this may lead to conditions like osteoarthritis, where the cartilage in joints deteriorates over time.
Collagen supplements can help alleviate joint inflammation, pain, and stiffness by encouraging gradual cartilage growth.
Hair and Nail Growth
Collagen is a major building block in structuring proteins like keratin, which plays a big role in the formation of skin, hair, and nails.
However, keep in mind that even the be͏st collagen s͏upplement brands may only have minor effects on your hair and nails. This is because collagen is first digested in the GI tract, meaning only a small amount will actually reach the hair and nails via the bloodstream.
Still, research shows that hydrolyzed eggshell membrane, a source of collagen, could boost hair growth and reduce breakage [5].
Additionally, a study reveals that collagen peptides could encourage nail growth and keep them from being brittle [6].
Gut Health
The body mostly contains types I and II collagen, and both can assist in maintaining healthy organ tissue. They also help relieve gut and GI tract inflammation, which could cause digestive imbalance [7].

Collagen Side Effects and Contraindications
While collagen products are likely safe for many healthy adults, be aware that there’s a low risk of minor side effects.
Digestive Discomfort
Generally, the discomfort linked to collagen supplements is relatively mild, including bloating, gastritis, heartburn, loss of appetite, and diarrhea.
Nevertheless, keep in mind that collagen supplements do change the composition of gut microbiota; some tests have shown that collagen derived from marine sources might irritate colitis patients.
Impact on Kidney Function
Collagen might cause kidney stones in some users due to the role of hydroxyproline. This major amino acid in collagen is disposed of through the kidneys as oxalate, a trigger for kidney stones.
As a result, people with kidney stones (or those prone to them) should avoid taking collagen supplements.
Allergic Interactions and Interactions With Medication
Collagen supplements might cause allergic reactions in sensitive users, such as itching, swelling, rash, and difficulty breathing. Before taking a new product, ensure you’re not allergic to any ingredients to avoid adverse effects.
Moreover, collagen supplements may also interact with certain medications. So, talk to your doctor if you take any medications before using any products for the first time—whether it’s collagen, nootropics, fat burners, or other dietary supplements.
How To Choose the Bes͏t Collagen Suppleme͏nt
When comparing the be͏st collagen s͏upplements, remember these things to pick the right one for your needs.
Types of Collagen Supplements
There are five major types of collagen, each serving specific functions in the body. The best collagen peptides are derived from these different types, providing targeted benefits, though both type 1 and 2 collagen make up about 90% of the collagen in your body [2].
The be͏st collagen s͏upplements usually contain types 1 through 5, though more research is needed to determine if you need all five kinds.
Collagen Sources
When looking for the be͏st collagen s͏upplement, it is vital to consider the source. For example, some of the best natural sources of collagen include marine ones, such as cold-water fish like salmon, and grass-fed bovine, chicken, beef, and eggshell.
Forms of Collagen Supplements
The be͏st collagen s͏upplement you can take orally is probably hydrolyzed collagen peptides because the collagen has been broken down into small peptides that are easier to digest.
Also, the be͏st collagen powder may be an unflavored option if you wish to easily mix it with any of your favorite foods or drinks. Yet, flavored options have an advantage, too, if you like specific tastes.
