The Impact of Collagen on Bone Health

Collagen's Role in Bone Strength

Collagen is a key protein that helps keep our bones strong and healthy. It makes up a large part of our bone structure, providing support and flexibility. As we age, our bodies produce less collagen, which can lead to weaker bones and a higher risk of fractures.

Collagen Supplements and Bone Density

Research shows that taking collagen supplements can help improve bone density. In one study, postmenopausal women who took 5 grams of collagen daily for a year saw an increase in their bone mineral density (BMD) by up to 7%. This suggests that collagen can be beneficial for maintaining bone health as we age.

Studies on Collagen and Osteoporosis

Several studies have looked at how collagen affects osteoporosis, a condition that weakens bones. Here are some key findings:

• Collagen supplements may help reduce bone loss in people with low bone density.
• A year-long study found that women taking collagen had better BMD compared to those who did not.
