Received Accepted Published Abstract Background The US Surgeon General s Report on Bone Health suggests America s bone-health is in jeopardy and issued a call to action to develop bone-health plans incorporating components of 1 improved nutrition 2 increased health literacy and 3 increased physical activity. Objective To conduct a Comparative Effectiveness Research CER study comparing changes in bone mineral density in healthy women over-40 with above-average compliance when following one of three bone health Plans incorporating the SG s three components. Methods Using an open-label sequential design 414 females over 40 years of age were tested 176 of whom agreed to participate and follow one of three different bone-health programs. One Plan contained a bone-health supplement with 1 000 IUs of vitamin D3 and 750 mg of a plant-sourced form of calcium for one year. .
