Collagen’s Role In Exercise Recovery & Skin Aging

Recent market research shows that the sale of collagen products grew by almost 83% between late 2018 to late 2019 and most of this growth was in the categories of skin, bone and joint health. Collagen in these sectors continue to grow and new research now also shows that collagen supports exercise recovery and plays an important role in fighting the effects of skin aging.

Exercise Recovery

Research suggests that collagen’s benefits are felt in other, maybe less obvious, areas of health including athletic performance and recovery from exercise! Since collagen is so prevalent in the body, maybe this isn’t really a surprise. In a study conducted in Germany, 180 young men and women with exercise related knee pain were given either a placebo or 5 grams a day of a patented type 1 collagen peptide for 12 weeks. During the course of the study subjects were asked to rate any perceived change in the knee pain while also being examined by a doctor. Results indicated that supplementation with the collagen significantly reduced knee pain in both self-reported and doctor-examined subjects.

Another study looked at the impact of specific collagen peptides on body composition and athletic performance in recreationally active women. Subjects consumed either a placebo or 15grams a day of collagen peptides while training 3x a weeks. Results showed that the collagen improved endurance performance (subjects ran farther), increased fat-free mass and gave greater muscular endurance.

Skin Aging

Collagen’s benefits to the skin have been well-documented, and two recent publications strengthen the existing body of knowledge in this area.

In the first, Korean researchers gave 84 middle-aged women 1gram/day of collagen tripeptide from marine sources for 12 weeks. Findings showed increased skin hydration, skin moisture, and skin tightness in the measured areas (face and forearms).

Lastly, a review and meta- analysis (results from many studies to determine potential effects) was carried out to assess the effect of collagen peptide supplementation on skin aging. Researchers found 19 double-blind, placebo controlled studies that indicated favourable effects of collagen in skin hydration, elasticity and wrinkles. Most of the results were also shown to be observed after 60 days of supplementation, and average amount of supplementation was between 2.5-5grams per day of collagen peptides.
