Registered summary

The aim of this clinical trial is to investigate the effectiveness of collagen, considered a new approach to prevent muscle mass loss after bariatric surgery, and to demonstrate the relationship between this effect and exercise. The key questions it aims to answer are: Does whey protein supplementation with collagen combined with resistance exercise prevent muscle mass loss after bariatric surgery? Do whey protein supplementation with collagen combined with resistance exercise affect fat mass after bariatric surgery? Researchers will compare collagen with whey protein.

Registered summary

Given the relatively high carbon footprint and sustainability of animal-based proteins, there is a growing interest in determining the nutritional quality non-animal-based protein sources. The overall objective of this investigation is to examine the impact of different animal and microbial-based protein sources to support whole body protein synthesis in adults. To do this, investigators will employ a 'breath test' method developed in our laboratory as well as urine sampling. The full summary is on the listing.

Registered summary

The purpose of this study is to evaluate and compare the effects of two different collagen supplement formulations on pain, physical function, and overall quality of life in adults with knee osteoarthritis. Knee osteoarthritis is a common joint disease characterized by cartilage degeneration, which leads to chronic pain and reduced mobility. While collagen supplements are frequently used to support joint health, their clinical effectiveness is usually measured using traditional pain scales. The full summary is on the listing.
