    Abstract : Background: Vitamin D deficiency, secondary osteoporosis and low-energy fractures (LEF) as side effects of specific drugs were first described more than half a century ago. These effects are recognized in guidelines where patients prescribed risk drugs are recommended follow-up with testing and supplementation. READ MORE

  6. 4. Vitamin D and blood pressure

    Author : Ann Burgaz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The physiological function of circulating 25-hydroxyvitamin D (25(OH)D) is to maintain serum calcium range that supports skeletal system. Evidence is mounting that vitamin D has beneficial effects on other important functions in tissues not primarily related to mineral metabolism. READ MORE

  7. 5. Vitamin A and Osteoporosis : Experimental and Clinical Studies

    Abstract : Vitamin A in high doses is severely toxic to the rat skeleton, and the active metabolite retinoic acid (RA) can induce bone resorption in vitro. An excessive dietary intake of vitamin A has been associated with reduced bone mineral density and an increased risk of hip fracture. READ MORE
