Collagen Peptides: What Are They, Benefits, Side Effects

collagen peptide benefits

Peptides are smaller versions of proteins. Many health and cosmetic products contain different collagen peptides for many uses, such as their potential anti-aging, anti-inflammatory, or muscle-building properties.

In this article, we discuss the potential benefits and side effects of peptide supplements.

What are collagen peptides?

Collagen peptides are short chains of amino acids extracted from native (full-length) collagen via a process called enzymatic hydrolysis (also enzymatic hydrolyzation).

So the native collagen (e.g. bovine hide) has to go through a softening process that allows the collagen peptides to be released from their bonds and safely extracted.

At a molecular level, collagen comprises three long amino acid chains that form a triple helix with a high molecular weight. As a result, collagen peptides are part of a tough and insoluble matrix of collagen fibers.

Improved skin barrier

The skin barrierTrusted Source is the body’s line of defense against bacteria, ultraviolet rays, pollution, and other toxins. 

The skin barrier can be damaged from over-exfoliation, exposure to cigarette smoke and other pollution, or even poor sleep. Peptides help build up a stronger barrier.

Reduced wrinkles

Collagen can plump skin and lips, and when skin is firmer and plumper, wrinkles and fine lines will be less visible.

More elastic skin

In addition to collagen, peptides also make up elastin fibers, also a type of protein. These fibers make skin look firmer and tauter.

Eases inflammation

Peptides can help ease inflammation, repair damaged skin, and even out skin tone.

Can help clear breakouts

Some peptides are antimicrobialTrusted Source, meaning they can kill bacteria that cause acne.



Side effects

For healthy individuals, peptide supplements are unlikely to cause serious side effects because they are similar to the peptides present in everyday foods.

Oral peptide supplements may not enter the bloodstream as the body may break them down into individual amino acids.

But, people should exercise caution when taking any supplements.

Topical creams and ointments containing peptides may cause skin symptoms, such as skin sensitivity, rash, and itching.

Individuals should always buy from a reputable company and discontinue use if adverse reactions occur.

Also, it is a good idea to speak to a doctor before taking peptide supplements or using topical products that contain peptides.

Those who are pregnant, breastfeeding, taking medications, or living with a medical condition should avoid using peptides until they speak to their doctor.
