Calcium is an essential mineral that is involved in many processes in the body. Around 99% of the calcium in the body is found in the bones and teeth. As a building block of bones, calcium is particularly important in the growth phase, for pregnant women and breastfeeding mothers, and for older people. In the event of a restricted or vegan diet or lactose intolerance, special attention should be paid to sufficient calcium intake. One calcium active Denk effervescent tablet a day with a refreshing orange flavour helps to meet the recommended calcium requirement.
