Peptides, particularly bioactive peptides derived from collagen (such as collagen hydrolysate), have been investigated for their potential benefits to bone health and the skeletal system. Scientific studies, both in vitro and in vivo, suggest that these peptides may stimulate osteoblast activity (cells responsible for bone formation) and enhance the synthesis of bone matrix proteins. Several clinical trials have shown that supplementation with collagen peptides can lead to modest improvements in bone mineral density in populations at risk for osteoporosis, such as postmenopausal women. The mechanism is thought to involve increased production of type I collagen, which is a major organic component of bone, as well as modulation of bone-resorbing osteoclasts. While more research is necessary to fully understand the extent of these effects and optimal dosing, the current body of evidence supports a scientific rationale for the use of specific peptides (notably collagen-derived) to support bone health. However, it is important to note that not all peptides have this effect, and the evidence is strongest for collagen peptides rather than unspecified or random peptide supplements. Thus, the evidence supports a moderate level of scientific validation for certain peptides in relation to skeletal system support.
