Collagen peptide is the most important protein in human body, ccounting for 30% of total protein content. It forms the "scaffold" of connective tissues—including skin, bones, joints, tendons, and cartilage—and plays a critical role in maintaining structural integrity, elasticity, and hydration. Composed of repeating amino acid sequences (primarily glycine, proline, and hydroxyproline), collagen exists in 28 distinct types, with Type I (skin, bones), Type II (joint cartilage), and Type III (blood vessels, organs) .
While the body synthesizes collagen naturally, production declines by 1-2% annually after age 25, accelerated by UV exposure, stress, and poor diet.  This is why the global demand for collagen peptide ingredient and supplements has aaccelerated in both healthy food, nutrtional supplements, and the skin care & beauty industry

Collagen peptides—broken down into small, absorbable fragments (2000-5000 Da)—is proven to penetrate the skin’s dermal layer. The daily intake of 2.5g of fish-derived collagen peptides for 12 weeks increased skin hydration by 15% and reduced wrinkle depth by 12% in women aged 35-55 according to a 2023 study in Nutrients. Inaddition, collagen can stimulate fibroblast activity, boosting the body’s natural production of Type I collagen and hyaluronic acid (a key moisturizing molecule), further enhancing skin elasticity and reducing hyperpigmentation.

Type II collagen (found in cartilage) and hydrolyzed Type I collagen support joint function by replenishing proteoglycans—molecules that cushion joints—and reducing inflammation. According to one 2022 meta-analysis in Arthritis Research & Therapy, 10g of daily collagen intake reduced joint pain by 30% in individuals with mild-to-moderate osteoarthritis, with 60% of participants reporting improved mobility. As is concerned about bones, collagen acts as a "glue" for calcium and minerals. Based on the clinical study, the daily intake of 5g of collagen combining with calcium can get bone mineral density increased by 4% over 18 months, lowering fracture risk.
Collagen’s amino acid composition (rich in glycine) helps strengthen the intestinal lining, a critical barrier against leaky gut syndrome. A 2024 study in Journal of Gastroenterology showed that collagen peptides reduce intestinal permeability by 22% in participants with irritable bowel syndrome (IBS), alleviating bloating and abdominal pain. Additionally, glycine supports stomach acid production, aiding protein digestion and nutrient absorption.
Collagen provides structural support to hair follicles and nail beds. It is found that 5g of daily collagen intake for 6 months increased hair thickness by 10% and reduced nail breakage by 40%. This is attributed to collagen’s role in delivering amino acids (e.g., proline) to keratin-producing cells, the building blocks of hair and nails.
Based on mentioned above, collagen peptide is widely used in functional food & beverage, being added into milk, oat milk, yogurt, products with clean-lable, and plant-based food & beverages. Also, in the healthy snacks, like black chocolate, protein bars, and gummies. Besides, some customers also choose to purchase pure collagen peptide powder, directly mixing it with milk, coffee, or tea, or simply water for daily collagen supplementation.
As consumer demand for sustainable, effective, and accessible products grows, innovations like recombinant collagen and nanotechnology are reshaping the industry—addressing animal sourcing concerns while boosting efficacy. For manufacturers, blending collagen with complementary ingredients (e.g., HA, probiotics) and adopting new production methods will be key to staying competitive. For consumers, choosing third-party-tested, high-purity collagen ensures safety and results.
