文摘

Calcium absorption from fumarate salts (calcium fumarate and calcium malate fumarate), which haverecently been considered for use as sources for food and beverage enrichment, was compared tothat from calcium citrate malate, calcium citrate, and calcium carbonate. Salts were instrinsically labeledwith ⁴⁵Ca and orally administered to Sprague-Dawley rats. Fractional absorption of calcium fromeach salt was determined using the femur uptake model. Fractional absorption from the five salts(0.30-0.27) was not significantly different (p > 0.05). Thus, when measured in the rat model, calciumfrom calcium fumarate and calcium malate fumarate is absorbed equally well as compared to othersalts, which are common calcium sources in many foods, beverages, and supplements.Keywords: Calcium salts; absorption; bioavailability; rats
