Collagen Products: What's More Important Than Content For Koreans, 'inner beauty' signifies more than just cosmetics. In recent years, alongside growing interest in skin health, the consumption of inner beauty products has surged. Among these, collagen stands out as one of the most prominent ingredients. However, the question 'Which collagen product is effective?' continues to demand an answer from consumers. Recent research has revealed that it's not merely the collagen content, but the 'GPH structure' that most significantly impacts the body's absorption rate. This provides crucial information that could change consumers' product selection criteria. Collagen is an essential protein found in human skin, bones, and joints, helping to maintain skin elasticity and overall health. However, as people age, collagen production capacity decreases, leading to signs of aging such as wrinkles and sagging skin. Consequently, more individuals are turning to various collagen supplements to replenish diminishing levels. A critical point here is that no matter how much collagen is consumed, it won't be effective if it's not properly absorbed by the body. Actual research findings indicate that collagen maintaining its GPH structure has an absorption rate approximately 54 times higher than general collagen. This implies the need for discernment in evaluating structural integrity, rather than simply choosing products based on content. So, what exactly is the GPH structure? GPH is an acronym for Glycine, Proline, and Hydroxyproline, referring to the unique collagen structure where these three amino acids repeat in a specific sequence. This distinctive form, with its repeating amino acid sequence of Glycine-Proline-Hydroxyproline, is designed identically to collagen found in the human body, giving it very high bioavailability. When this structure is maintained, collagen can be efficiently absorbed by the body and genuinely contribute to improving skin health. Conversely, collagen with a destroyed GPH structure simply breaks down, transforming into ordinary protein and losing its inherent collagen function. Therefore, when choosing a collagen product, it is far more important to verify whether the GPH structure is maintained rather than simply relying on marketing claims of 'high content'. Technological differences among collagen manufacturers determine product quality and efficacy. A notable example in this field is Evercollagen, the flagship brand of the domestic company Nutri. Evercollagen has continuously engaged in collagen R&D for 25 years, commercializing technology that applies collagen raw materials with the same GPH structure as human collagen. A distinctive feature is its continued product design, which considers bioavailability by utilizing proprietary enzyme decomposition technology. Enzyme decomposition technology is a sophisticated process that appropriately reduces the molecular size of collagen while preserving its GPH structure, thereby maximizing both absorption rate and efficacy simultaneously. Another strength of Evercollagen lies in its strict raw material management system. By operating a thorough management system that completes processing within 24 hours of acquiring raw materials, it maximizes the preservation of their freshness. Since collagen is a sensitive ingredient that can oxidize and undergo structural changes over time, maintaining freshness is a critical factor determining the quality of the final product. The standard of completing processing within 24 hours is stringent even within the industry, requiring the entire process, from raw material supply chain to manufacturing, to be organically linked to uphold it. Through this system, Evercollagen focuses on securing the safety and consistent quality of its functional ingredients, establishing a foundation to produce products of the same standard for each batch. Based on this technology and management system, Evercollagen earned consumer trust by ranking first in the 'KPEI Inner Beauty Collagen' category. KPEI is an index directly evaluated by consumers, making it highly significant as it is based on actual user experience. This can be seen as a case where technological excellence led to consumer satisfaction. Furthermore, it serves as evidence that scientific evidence and technological prowess, rather than marketing emphasizing high content, become real competitive advantages in the market. Scientific Basis of GPH Structure So, how should consumers choose products? This research emphasizes that when selecting collagen products, consumers should not merely look at the content, but meticulously examine whether the GPH structure is maintained and the technology used to preserve it. Even if a product label indicates high collagen content, whether it is actually absorbed and effective in the body is a separate issue. The 54-fold difference in absorption rate clearly demonstrates how crucial GPH structure maintenance is in product selection. In the
