The Ultimate Guide of Incorporating Collagen into Your Diet

What are Collagen Peptides?

Collagen peptides, also called collagen hydrolysates, are short chains of amino acids derived from collagen. Collagen is the most abundant protein in the human body and is a major component of connective tissues such as skin, bones, tendons, ligaments and cartilage.

Collagen peptides are produced through a process called hydrolysis, which breaks the long collagen protein strands into smaller pieces that are more easily digested and absorbed. The resulting collagen peptides are soluble in water and have a neutral taste and odor. When taken as supplements, collagen peptides can provide the building blocks for your body to produce new collagen.

Collagen Peptides vs. Collagen Protein

Collagen peptides are different from undenatured collagen proteins. Collagen protein is harder for the body to absorb, while collagen peptides have been broken down into smaller components that are more bioavailable.

Common Sources of Collagen Peptides

Collagen peptides are commonly sourced from bovine, porcine, marine or chicken collagen. Each source provides different amino acid profiles. Bovine collagen peptides are richest in type I and III collagen, while marine collagen provides more type I.

The Science Behind Collagen Peptides

Collagen peptides have been extensively studied for their potential health benefits. Here’s an overview of the science:

Bioavailability

Collagen peptides have a low molecular weight that allows 90-100% absorption. Larger undenatured collagen is less bioavailable at only 10-15% absorption.

Collagen Synthesis

Ingested collagen peptides provide glycine, proline and hydroxyproline that your body uses to produce new collagen fibers and maintain tissues.

Anti-Aging

Collagen declines with age. Supplementation can counteract deficiency. Peptides stimulate fibroblasts for increased collagen, elastin and hyaluronic acid.

Joint and Bone Health

Collagen is abundant in cartilage and bones. Supplements support cartilage matrix production and may reduce inflammation and deterioration.

Skin Elasticity and Hydration

Collagen peptides increase dermal collagen content. This leads to improved skin elasticity, moisture and reduced wrinkles.

Overall the evidence supports collagen peptide supplementation for reducing signs of natural aging and supporting joint, skin, hair and nail health. More human clinical trials are still needed for many potential benefits.

Choosing the Right Collagen Peptide Supplement

Look for a quality collagen peptide product with:
