The collagen triple helix, also called procollagen, undergoes post-translational modifications to become a basic collagen molecule (also called tropocollagen). Proline and hydroxyproline are commonly one of the other two amino acids in the repeating sequence. About a third of the amino acids in collagen are glycine because glycine is always the first amino acid in the repeating sequence of three amino acids that forms the α-chains-the hydrogen bonds between adjacent glycine molecules is what gives the triple helix its strength and stability. And yet, all collagens are based on a characteristic triple helix tertiary structure, which is formed by three polypeptide chains (long chains of amino acids, called α-chains, each predominantly composed of a repeating sequence of three amino acids, and varying in length from about 600 amino acids to over 3000 amino acids long) that tightly twist around each other. There are 29 currently-identified genetically-distinct types of collagen (given roman numerals in order of discovery), encoded by at least 46 genes, and categorized by their quaternary structures and architecture, i.e., how collagen molecules link together in different ways in order to perform various functions. We don’t make it as well when we age or are stressed or inflamed, and that’s not cool. TL DR? Collagen is a crazy important protein in our bodies and it does a bunch of awesome things.

Head’s up: this is about to get very sciency, so feel free to skip to the next section. I want to dig into the forms and functions of collagen in even more detail, since it’s relevant to some collagen supplement claims. The word collagen is derived from the Greek “kólla,” which means glue, although collagen functionally acts both as a glue-holding our cells, tissues and organs together-as well as a structural scaffold.
It’s also abundant in muscles, blood vessels, corneas, and teeth. Let’s begin with what collagen actually is so we can understand why we stand to benefit from consuming it.Ĭollagen is the most abundant protein in our bodies, accounting for approximately 30% of all our proteins, and is our dominant structural protein, including being a main building block of connective and interstitial tissues, bone, cartilage, ligaments, tendons, and skin.
bovine hide collagen peptides, marine collagen and multi-collagen) and what to look for on (and off!) labels. Then, we’ll compare how the various supplemental forms are extracted and processed, their digestibility, the relevance of the source material ( c.f. First, we’ll dive into what exactly collagen is and the biological effects of increasing intake whether from supplements or food sources.

So, let’s dissect the three main collagen supplements that form the basis of the full range of products on the market: gelatin, collagen peptides (also called hydrolyzed collagen, collagen hydrolysate, gelatin hydrolysate, or collagen protein), and bone broth protein. Not all collagen supplements are created equal. According to the market research firm Nutrition Business Journal, the global market is projected to reach $7.5 billion by 2027.Īs the market saturates with collagen-based products and manufacturers vie for your dollar (not to mention brand loyalty) with compelling claims, it’s important to be an informed consumer. While American consumers spent about $50 million on collagen supplements in 2014, we’re expected to spend upwards of $293 million on collagen supplements in 2020. There’s gelatin, collagen protein, collagen peptides, hydrolyzed collagen, collagen hydrolysate, marine collagen, multi-collagen, bone broth collagen, and bone broth protein, each packaged and sold in an ever increasing collection of products, from protein powders to protein bars, cookies, beverages, coffee creamers, capsules, gummies, and more. The collagen supplement market is booming.
