Rating (out of 5): 2

Hydrolyzed beef collagen is increasingly used as a dietary supplement to support exercise, primarily for its potential effects on joint health, muscle recovery, and connective tissue integrity. Scientific interest in collagen supplementation stems from its high content of amino acids such as glycine, proline, and hydroxyproline, which are important for collagen synthesis in the body. Some randomized controlled trials suggest that collagen peptides, including those derived from beef, may benefit joint health in physically active individuals. For example, a few studies have shown modest improvements in joint pain and mobility in athletes with activity-related joint discomfort after several weeks of collagen supplementation. There is also preliminary evidence suggesting that collagen may help with muscle recovery by supporting connective tissue repair, though these findings are not robust or universally confirmed. However, the direct impact of hydrolyzed beef collagen on exercise performance, muscle strength, or hypertrophy is limited and not well established. Most available evidence relates to joint and tendon health rather than direct athletic performance. Studies are often small, sometimes industry-funded, and results can be variable. Consequently, while there is some scientific basis for using hydrolyzed beef collagen to support aspects of exercise, particularly in the context of joint health and recovery, the overall strength of evidence remains moderate to low (rated as 2/5), and further high-quality, independent research is needed to draw definitive conclusions.
