Study Supports Collagen for Bone Health
A new study published in the December 2009 issue of the Journal Bone builds on science supporting the effectiveness of a hydrolyzed collagen supplement for bone health.
Hydrolyzed collagen is a protein that plays an important role in our bones and cartilage. The protein can be found in supplement form and is said to slow the aging process, improve joint and bone health and benefit the skin.
For the study, researchers from the French National Institute for Agricultural Research divided mice into three groups:
1. Mice with their ovaries removed to mimic postmenopausal women
2. Mice with their ovaries removed that were given collagen supplements
3. Normal mice with their ovaries, acting as the control group
After twelve weeks, the researchers observed a reduction in bone mineral density (BMD) among the mice with no ovaries that were not given the collagen supplement but no reduction in BMD was seen among the supplement group.
A marker of bone resorption, called carboxy terminal telopeptide, was also lower among the supplement group. Bone resorption is the process by which bones are broken down and dissolved into minerals such as calcium, phosphates and salts, which weakens the bones.
Further studies with humans are necessary to confirm these findings but the researchers noted that we will likely see collagen emerge as a key player in the bone health market in the near future.
