It is known that collagen is a protein of great importance for bones, tendons, cartilage, muscles, skin, hair and nails. There are several types of collagen, and type II is the main component of the joint cartilage matrix and can help prolong the independent lifestyle of an elderly person, improving their quality of life. The research aimed to evaluate the effect of a collagen mix composed of peptides, type II collagen and nutrients involved in the joint bone metabolism of active elderly. Volunteers with a minimum age of 60 years and physically active participated in the research. This is a non-randomized clinical trial conducted with the gymnastics group of the elderly of an Activity Center in Florianópolis – SC. Oral supplementation with the collagen mix composed of bioactive peptides of hydrolyzed collagen, intact type II collagen, silicon and nutrients involved in joint bone metabolism (Duo flex®) was administered for 90 days, and the next 30-day cycle of the supplement was always delivered before the end of the current cycle, so that the participants did not interrupt the treatment. These were also followed weekly via telephone contact to avoid withdrawal or interruption of treatment. Questionnaires were applied to evaluate symptoms related to sarcopenia, joint functionalities, characteristic skin, nails and hair health, and anthropometric measurements. The sample consisted of 50 elderly, most of them female (72%). Product consumption reduced pain, decreased stiffness and improved joint mobility according to the WOMAC questionnaire result. Duo flex® has significantly improved joint health and therefore can be an effective solution to delay joint manifestations. The results suggest that collagen mix can be used as a therapeutic approach for physically active elderly.
