Maintaining strong bones as we age is crucial to the prevention of osteoporosis (1). Bones are primarily made of collagen, which provides them with structure and support. Research has shown that the consumption of collagen has a positive influence on bone composition, strength and bone mineral density (2), and positive therapeutic effect on osteoporosis (3). In a study of 66 postmenopausal women, daily intake of specific collagen peptides was shown to increase the bone mineral density of the spine and femoral neck (2).
