I am a runner and was restricted due to pain in my knees. Calcium and glucosimine suppliments were not effective, until I learned that Vitamin K is crucial for calcium absorption. In Japan Vitamin K is prescribed for osteoporosis. I am now able to run without pain. I take about 5 times the RDA daily of vitamin K with my calcium.
