Taking an active approach to health with optimized collagen peptides

Collagen peptides are reaching unprecedented heights, riding the wave of the growing popularity and acceptance of protein and collagen. The *2025 Condition-Specific Report* by the *Nutrition Business Journal* describes them as the "Swiss Army Knife of health solutions," highlighting their wide-ranging benefits across beauty, sports, and anti-aging sectors. Indeed, collagen has secured a strong foothold in several health supplement markets: women's health (ranking in the top six for both market share and growth rate in 2024), bone and joint health (growing by 21.4%), "beauty-from-within" (poised to overtake B vitamins as the category's leading ingredient, contributing nearly 70% of growth in 2024), and healthy aging (sales grew by 26% in 2024, with no signs of slowing down¹).

However, as brands rush to capitalize on this trend, the market has been flooded with a multitude of collagen supplements and ingredient variants. As is common in the supplement industry, not all of these products are equally effective. To develop products that deliver specific health benefits, developers must understand the differences between various collagen peptides and establish criteria for selecting the type that best aligns with their formulations, applications, and customer expectations.

Gelita, a company with 150 years of history in collagen research and innovation, points out that four key aspects should be considered when selecting collagen peptide ingredients: market expectations and product positioning; the scientific basis and importance of health claims for the ingredient; production and cost-efficiency; and the support services provided by the supplier. Fundamentally, Gelita views the selection of collagen ingredients for product formulations not merely as a choice of raw materials, but as a strategic business decision.

Above all, it is essential to select collagen peptides optimized for the specific health benefits you aim to deliver. Thanks to advancements in collagen peptide production technology, optimized, bioactive forms are becoming the new market standard; these forms can target specific collagen reserves and production mechanisms, delivering precise results where needed and offering specific health benefits that go beyond basic nutritional value. The Vital Role of Collagen

To select the right collagen peptides, one must first understand the role collagen plays in the human body. Collagen is the most abundant protein in the body and a primary component of all connective tissues—including skin, muscles, bones, and joints. In its native form, it is a large, complex protein with a triple-helix structure that the body struggles to absorb and process. Collagen peptides, however, are natural, small-molecule collagen fragments produced through hydrolysis; they are far more easily absorbed and utilized by the body. Native collagen cannot be absorbed directly; it must first be broken down into peptides or amino acids.

Through proprietary processes, Gelita has developed a range of Bioactive Collagen Peptides® (BCP) characterized by high bioavailability and physiological activity. Unlike ordinary collagen peptides, BCPs can target specific connective tissue cells—such as fibroblasts in skin and tendons, chondrocytes in joints, and osteoblasts in bone—stimulating them to produce more collagen and thereby delivering specific health benefits.

The key to Gelita’s BCP lies in its production process. Derived from natural sources like bovine hide, bovine bone, porcine skin, or fish, the collagen undergoes extraction and enzymatic hydrolysis. During this process, the triple-helix structure is dismantled, and long-chain proteins are hydrolyzed into shorter segments; further hydrolysis yields highly specific short peptides. This method not only ensures a high level of product safety but also allows for the precise creation of peptides with specific, defined functions.

Gelita’s BCP range also boasts exceptional bioavailability, with studies showing an absorption rate of at least 98%. Notably, approximately 10% of the ingested BCP remains intact during digestion, effectively stimulating cellular metabolism. In essence, this means Gelita BCP offers a dual advantage: it delivers collagen directly to target areas to serve as building blocks while simultaneously acting like a key in a lock to activate local cells to produce new collagen—a process known as bioactive stimulation. The result is precise renewal and repair, acting exactly where it is needed most. Classification of Collagen

Scientists have identified nearly 30 types of collagen in the human body; however, because the hydrolysis process yields extremely small peptide fragments, the original source and specific collagen type are no longer considered relevant or determinable factors. What truly matters is the structure and size of the peptides, rather than the specific type of native collagen from which they originated. Consequently, supplement formulators should prioritize the product's bioactivity over the source of the collagen.
