What is Collagen?

Collagen is an abundant, fibrous, structural protein found throughout the human body.  It is most notably present in skin, and connective tissue such as tendons, ligaments, and cartilage.  Collagen is also a major component of the eyes, bone, blood vessels, and of course, the digestive system.  The word collagen originates from the Greek word kólla, meaning glue (i.e., produced from boiled animal skins, tendons, etc).  In essence, collagen holds the body together.

Types of Collagen

While there are as many as 28 types of collagen, the majority of the collagen within the body is comprised of Type I, II, and III.

  • Type I, found in: skin, tendons, ligaments, artery walls, organs, bone, etc.
  • Type II, found in:  cartilage
  • Type III, found in:  liver, bone marrow, heart, etc.

Possible Benefits of Collagen Peptides and Protein

For many people, the first benefit of collagen that comes to mind involves hair, nails, skin, and joints.  While hair, nails, skin, and joints can certainly benefit from supplemental collagen,  the rest of the body may as well. Similar to colostrum, collagen may help to speed up post-workout recovery.  It has also been shown to aid in the repair of the digestive tract and reduce permeability issues (leaky gut).

Other benefits may include:

  • Build and repair muscle
  • Anti-aging (skin)
  • System detoxification (glycine content)
  • Great for joints and bones
  • Strengthen connective tissue
  • Helps repair gut lining

To receive the maximum benefit of collagen supplementation, be sure take a good Vitamin C supplement along with it.  See below for recommendations.

Possible Side Effects

Side effects tend to be rare but may include:

  • Allergic reactions
  • Calcium overload (marine sourced collagen) 

What to Look For

When purchasing collagen, be sure to choose / consider the following:

  • Country of origin (US, Canada, New Zealand are best for been collagen)
  • Animal source, depending on needs / allergies: egg, chicken, beef, fish, etc.
  • Miminal or no additives or fillers
  • Produced by grass-fed cows in the case of beef collagen
  • Organic and / or non-GMO
  • Antibiotic-free, hormone-free, and pesticide-free
