If you ingest Calcium and Zinc and Iron the body will prioritize the calcium over the other two. That is why sports nutritionists and most smart supplement companies advise athletes to take Iron and Zinc at a time when there is little or no calcium in the stomach. This goes for the Zinc containing supplement ZMA as well.


"It appears unlikely that calcium per se has a negative effect on zinc absorption. We added calcium to cow’s milk formula to a level of ~1300 mg/L and found no significant difference in zinc absorption from the formula with the regular level of calcium (500 mg/L) through the use of radioisotopes in human adults and paired observations (Lönnerdal et al. 1984 ). Similarly, Spencer et al. (1984) and Dawson-Hughes et al. (1986) added large amounts of calcium to a meal and found no effect on zinc absorption in human adults. It also appears that the long-term use of calcium supplements has no effect on zinc status; Gambian women who were given 1000 mg calcium/d had plasma zinc concentrations similar to those of unsupplemented women (Yan et al. 1996 )."
