Increased Bone Density
Your bone density decreases when the amount of protein in your body drops to a certain level.
Figure A shows the results of bone density measurements when one group of mice that had a low level of protein were given feed that contained only 6% or 10% milk casein (protein) for 10 weeks, and another group of mice were given feed that contained 6% milk casein and 4% collagen for 10 weeks. This shows that the bone density of mice with a low level of protein that are given feed containing collagen increases more than the other group.
In addition, when collagen is taken in conjunction with oral hormone control drugs by patients with osteoporosis, it has been reported that bone degradation can be controlled.
