Registered summary

The goal of this clinical trial is to learn whether a natural marine supplement called NT-II™ (Salmon Undenatured Type II Collagen) can help lower knee discomfort caused by physical activity in otherwise healthy adults. Many active people experience knee pain when performing daily movements like climbing stairs, walking long distances, or squatting, even if they do not have a medical diagnosis such as arthritis. This discomfort can limit mobility, impact exercise routines, and reduce overall quality of life. The full summary is on the listing.
