Efficacy and tolerability of an undenatured type II collagen supplement in modulating knee osteoarthritis symptoms: a multicenter randomized, double-blind, placebo-controlled study
Abstract
Background: Undenatured type II collagen (UC-II) is a nutritional supplement derived from chicken sternum cartilage. The purpose of this study was to evaluate the efficacy and tolerability of UC-II for knee osteoarthritis (OA) pain and associated symptoms compared to placebo and to glucosamine hydrochloride plus chondroitin sulfate (GC). Methods: One hundred ninety one volunteers were randomized into ...

Effect of enzymatically cross-linked tilapia scale collagen for osteoblastic differentiation of human mesenchymal stem cells
Abstract
Type I collagen is an abundant component of bone tissue that has been used for bone tissue engineering using various cross-linking methods, including chemical agents, ultraviolet irradiation, and dehydrothermal treatment to enhance its physical properties. Collagens derived from mammalian animals are generally not used for implantable scaffolds owing to the potential for zoonotic infection. In addition, the toxicity of cross-linking agents and alteration of ...

Dietary Supplementation with Specific Collagen Peptides Has a Body Mass Index-Dependent Beneficial Effect on Cellulite Morphology
ABSTRACT In this double-blind, placebo-controlled clinical study, we investigated the efficacy of specific bioactive
collagen peptides (BCP) on the cellulite treatment of normal and overweight women. In total, 105 women aged 24–50 years
with moderate cellulite were randomized to orally receive a daily dosage of 2.5 g BCP or a placebo over 6 months. The degree
of cellulite was evaluated before starting the treatment and after 3 and 6 months of intake. In ...

Daily oral consumption of hydrolyzed type 1 collagen is chondroprotective and antiinflammatory in murine posttraumatic osteoarthritis
Abstract
Osteoarthritis (OA) is a degenerative joint disease for which there are no disease modifying therapies. Thus, strategies that offer chondroprotective or regenerative capability represent a critical unmet need. Recently, oral consumption of a hydrolyzed type 1 collagen (hCol1) preparation has been reported to reduce pain in human OA and support a positive influence on chondrocyte function. To evaluate the tissue and cellular basis for these effects, ...

Cyclic Mechanical Stretch Induced Smooth Muscle Cell Changes in Cerebral Aneurysm Progress by Reducing Collagen Type IV and Collagen Type VI Levels
Abstract
Background/Aims: Cerebral aneurysm growth is characterized by continuous structural weakness of local smooth muscle cells, though the mechanism is unclear. In this study, we examine protein changes in cerebral aneurysm and human brain vascular smooth muscle
cells after cyclic mechanical stretch. We further explore the relationship between the smooth muscle cell changes and reductions in the levels of collagen types IV and VI. ...

Collagen-derived peptides modulate CD4þ T-cell differentiation and suppress allergic responses in mice
Abstract
Introduction: Collagen peptides have been widely used as a food supplement. After ingestion of collagen peptides, oligopeptides containing hydroxyproline (Hyp), which are known to have some physiological activities, are detected in peripheral
blood. However, the effects of collagen-peptide administration on immune response are unclear. In the present study, we tested the effects of collagen-peptide ingestion on allergic response and the effects of collagen-derived oligopepti...

Collagen peptides improve knee osteoarthritis in elderly women A 6-month randomized, double-blind, placebo-controlled study
ABSTRACT: As the global population gets older, joint-related health concerns are increasingly common, such as osteoarthritis causing pain and reducing mobility. Collagen peptides have been proposed as nutraceuticals to improve joint health in patients with osteoarthritis. We performed a prospective, randomized, double-blind, placebocontrolled study in elderly women with mild-to moderate knee osteoarthritis and showed that the oral intake of collagen peptides for a ...

Collagen peptide supplementation in combination with resistance training improves body composition and increases muscle strength in elderly sarcopenic men: a randomised controlled tria
Abstract
Protein supplementation in combination with resistance training may increase muscle mass and muscle strength in elderly subjects. The objective of this study was to assess the influence of post-exercise protein supplementation with collagen peptides v. placebo on muscle mass and muscle function following resistance training in elderly subjects with sarcopenia. A total of fifty-three male subjects ...
