Collagen peptides are supported by a growing body of scientific evidence for their role in supporting bone health and the skeletal system. Collagen is a primary structural protein in bones, comprising about 90% of the organic bone matrix. As we age, collagen production declines, which can contribute to reduced bone density and strength. Several randomized controlled trials and preclinical studies have investigated the effects of collagen peptide supplementation on bone health.

Human studies, such as a 2018 double-blind, placebo-controlled trial published in Nutrients, found that daily supplementation with specific collagen peptides improved bone mineral density in postmenopausal women with age-related bone loss. The study suggested that collagen peptides may stimulate osteoblast activity (cells responsible for bone formation) and promote bone matrix synthesis. Animal studies have also demonstrated enhanced bone strength and improved bone microarchitecture following collagen peptide supplementation.

While the precise mechanisms are still being elucidated, the evidence indicates that collagen peptides can enhance bone metabolism and support the maintenance or improvement of bone density, especially in populations at risk for osteoporosis. Although more large-scale studies are warranted, current research justifies the use of collagen peptides as a supportive strategy for skeletal health.
