Americans spent nearly $300 million on collagen supplements in 2020 and the global market is expected to grow. As the most abundant protein in our bodies and a key structural component of our skin, muscles, bones, blood vessels, and connective tissue, collagen’s appeal is clear.
The typical Western diet may not contain collagen, and over time, our bodies may produce less collagen due to the natural aging process or chronic inflammation, stress, nutritional deficiencies, or smoking. Although there are no blood tests to measure collagen levels, this decrease can become apparent with wrinkling of the skin due to loss of elasticity, joint stiffness, bowel or digestive problems, and longer recovery times from injury.
The market is flooded with collagen-based products, from collagen peptides to bone broth proteins, which are produced in a variety of digestible environments.
Gelatin is nutritionally equivalent to collagen. One tablespoon of gelatin contains about six grams of protein.
Both gelatin and collagen contain the same 19 amino acids. However, they are structurally completely different. Gelatin is basically a denatured and hydrolyzed form of collagen. This means that when you expose the triple helix structure of collagen to heat and water, you get the shorter chains of amino acids found in gelatin and bone broth proteins. You will also often see products with “collagen peptide” – this simply means that the collagen is further hydrolyzed by the enzymes used in the manufacturing process.
Collagen and gelatin have about the same digestibility – both are well absorbed. Digestibility is measured as the percentage of amino acids in an ingested protein that is absorbed (mostly in the small intestine) relative to what is excreted from the body.
Most of us have experienced gelatin like jelly as children or during hospital stays (it’s been around since 1890). When you heat gelatin, the heat energy breaks the weak bonds that hold the gelatin together. Then, as the mixture cools, the chains are restored, but not perfectly, giving the jelly its unique semi-solid structure.
Gelatin is also found in marshmallows, sweet corn, gummy bears, and jelly beans.
The best way to reap the benefits of collagen or gelatin is to drink a cup of bone broth daily or add hydrolyzed collagen (collagen peptides) to hot or cold drinks. Collagen peptides dissolve in hot or cold drinks without gel formation.
If you love eating gelatin, maybe you could consider jelly, gelatin cubes, or healthy fudge, which are very popular among customers. If you are jelly or gummy bears manufacturer, maybe your could consider a good supplier who offers high-quality gelatin products and stable supply.
