    Effect of Vitamins D2 and D3 Supplement Use on Serum 25OHD Concentration in Elderly Women in Summer and Winter

    Vitamin D2 and D3 are generally considered equipotent in humans. A few studies have reported that serum 25OHD levels are higher in vitamin D3- compared with vitamin D2-supplemented subjects. As both vitamin D2 an...

    Reference range for 24-h urine calcium, calcium/creatinine ratio, and correlations with calcium absorption and serum vitamin D metabolites in normal women

    A study of 959 black and white women shows that the normal range for 24-h urine calcium excretion in white women is 30–300 mg and 10–285 mg in black women. Clinical laboratories use a normal range for 24-h uri...
