Collagen Powder Nutrition Facts
Overview of Collagen Powder Composition
High Protein Content and Amino Acid Profile
Collagen powder is primarily known for its high protein content. Feed collagen protein powder (FCPP) derived from dechromed leather scrap contains approximately 500 grams per kilogram of crude protein and includes 18 different amino acids1. This makes it a rich source of essential and non-essential amino acids, which are crucial for various bodily functions, including muscle repair and skin health.
Low Chromium Content
One of the significant concerns with collagen derived from leather scrap is the potential presence of chromium. However, studies have shown that the chromium (III) content in FCPP is less than 10 mg per kilogram, and no chromium (VI) was detected, making it safe for consumption1.
Digestibility and Utilization
Digestibility in Animals
The digestibility of collagen powder has been evaluated in various animal models. In castrated male pigs, the digestibility of dry matter, crude protein, ash, and gross energy (GE) in FCPP was found to be 76.6%, 84.6%, 49.8%, and 77.0%, respectively1. This indicates that a significant portion of the nutrients in collagen powder is bioavailable and can be effectively utilized by the body.
Utilization in Poultry
In broiler chicks, the total utilization ratio of actual amino acids (TAAA) from FCPP was estimated to be 68.7% using the total metabolizable energy (TME) biological evaluation method1. This high utilization rate suggests that collagen powder can be an efficient protein source in poultry diets.
Health Benefits of Collagen Powder
Muscle Anabolism in Older Adults
Collagen hydrolysate, when blended with milk protein, has been shown to stimulate muscle protein synthesis (MPS) in older adults. A study comparing a 20 g blend of collagen protein hydrolysate and milk protein (CP+MP) with a non-blended milk protein source (MP) found that both resulted in equivalent increases in MPS2. This suggests that collagen powder can be an effective supplement for maintaining muscle mass in older adults.
Enhanced Collagen Synthesis
Supplementation with vitamin C-enriched gelatin, a form of collagen, has been shown to significantly increase collagen synthesis. In a study involving healthy male subjects, those who consumed 15 g of gelatin before exercise showed double the amino-terminal propeptide of collagen I in their blood, indicating enhanced collagen synthesis3. This suggests that collagen powder can play a beneficial role in injury prevention and tissue repair.
Skin Health Improvement
Collagen peptides are also used in nutricosmetic products to improve skin health. Clinical trials have demonstrated that oral supplementation with specific collagen peptides can improve skin hydration and the dermal collagen network. These peptides have been shown to enhance skin barrier function, induce the synthesis of collagen and hyaluronic acid, and promote fibroblast growth and migration4. This makes collagen powder a valuable supplement for improving skin appearance and health.
Conclusion
Collagen powder is a highly nutritious supplement with a rich amino acid profile and high protein content. It is easily digestible and bioavailable, making it an efficient protein source. Its benefits extend beyond basic nutrition, contributing to muscle anabolism, enhanced collagen synthesis, and improved skin health. These attributes make collagen powder a versatile and beneficial addition to various dietary regimens.
