Abstract: This review examines 2026 research data on collagen peptides, focusing on safety, efficacy, and industry trends. While generally well-tolerated, mild side effects such as digestive discomfort or skin reactions are reported in rare cases. Comparative analysis of marine, bovine, and porcine sources highlights differences in bioavailability and allergenicity. Industry growth is driven by functional food and beauty-from-within trends. Selection guidelines emphasize peptide molecular weight, purity, and third-party testing. Emerging evidence supports benefits for joint, skin, and bone health, though long-term safety data remain limited.
