A Florida State University (FSU) clinical trial finds that SOLUGEL® supplementation for active middle-aged adults not only helps to relieve joint pain and increases their daily living activities but now also has a proven effect on the mental well-being of this demographic group.

The study participants were all between 45 and 65 years old, spent at least three hours a week on activities such as hiking or cycling, had no specific pathology, but suffered from joint pain. After 6 months, the study revealed that regular intake of 10 grams of SOLUGEL® lead to a significant results: 

Improvement of knee functionality. Participants experienced a significant reduction in pain and improvement in knee functionality, as indicated by the Knee Injury and Osteoarthritis Outcome Score.

Increased daily activity levels. Collagen peptides positively impacted the daily living activities (ADLs) of the participants (such as commuting, cleaning, and shopping), while the placebo group showed no change.

Improved mental health. SOLUGEL® collagen peptides also improved mental health scores, while none of the participants in the placebo group saw any improvement.

1. What are SOLUGEL® collagen peptides?

Group 13

Collagen peptides, which are also known as collagen hydrolysate or hydrolyzed collagen, are a highly digestible protein obtained through the enzymatic treatment of collagen-rich materials.
Sourced from the highest quality raw materials, the bioactive SOLUGEL® collagen peptides are produced from a strictly controlled process that uses a unique biotechnology which results in consistently premium quality.

2. What is collagen?

Group 13

Collagen is the most abundant protein in the human body and it accounts for over 30% of the body’s protein. As the key building blocks that provide support and structure to our bodies, collagen is present in all connective tissues such as skin, bones, cartilage, tendons, ligaments and blood vessels. As the structural framework of the body, collagen plays a crucial role in terms of supporting and connecting everything together.

3. What is the difference between gelatin and collagen peptides?

Group 13

Gelatin and collagen peptides are both natural products that are extracted from collagen-rich materials. While gelatin is an ingredient that is typically used as a gelling agent, emulsifier, stabilizer or water binding agent for confectionery, dairy, desserts and pharmaceutical applications, collagen peptides are predominately consumed for the nutritional value and health benefits, as well as easy integration in food and beverages.​

4. How is SOLUGEL® absorbed by the human body?

Group 13

Collagen peptides are further hydrolyzed into smaller peptides or even free amino acids along the human digestive tract. They can also easily be absorbed in the intestine. Tests have proven that they reach the bloodstream within 15 minutes and are available to exert different functions in target tissues. The presence of peptides reached a maximum level after 1-2 hours and then decreased to one-half of the maximum level 4 hours after the ingestion.
