A Tufts University study, published in the April 2002 issue of the American Journal of Clinical Nutrition, suggests a high protein diet plus adequate intakes of calcium and vitamin D may benefit bone health. Researchers compared the effects of calcium and vitamin D supplementation vs. a placebo in 342 healthy elderly men and women (age 65 and older).
Study participants either consumed a 500 mg. per day supplement of calcium in addition to the approximately 700 mg. per day of calcium derived from their diet, with approximately 200 IU per day of vitamin D or placebo for three years. Although the calcium intakes were below the recommended daily allowance (RDA), they were higher than the majority of people in this age group. However, protein intakes were generally above the RDA at between 79 and 96 grams per day.

According to lead researcher Bess Dawson-Hughes, M.D., "We found that protein has a favorable effect on changes in bone density if you have an adequate calcium and vitamin D intake. Some studies show protein is harmful to bone, others show it is not... [our results] may help to explain the variety of findings out there. It depends how much calcium and vitamin D the groups consume whether you'd see a positive effect. It raises the possibility that the elderly might benefit from more than the current RDA [of protein]."
While the Tufts University study was confined to elderly individuals, it is noteworthy because the findings could apply to the general adult population as well. As a result, we recommend that all those living a high protein lifestyle make sure that their calcium and vitamin D intakes are adequate.
New Keto Calcium is a convenient way high protein dieters can assure they are consuming beneficial amounts of calcium and vitamin D. Keto Calcium contains a daily recommended amount of 500 mg. of calcium (hydroxyapatite form - highest absorption calcium), plus 400 IU of vitamin D in addition to a mineral complex including magnesium with Betaine HCL to aid mineral absorption.

"While you are limiting the amounts of sugar and (lactose containing) dairy products in your diet, you may also need to increase the amount of protein you eat—especially if you are female. Protein is absolutely essential for repairing damage done by free radicals. A lack of adequate protein in your diet prevents cellular repair and puts you on the fast track to aging. In my practice, I have consistently noticed that people who look older than their chronological age (yet are not suffering from any known disease) invariably have low protein intake."
