Calcium is an essential ingredient for maintaining healthy bones, teeth and muscles. In addition, it supports the nervous and endocrine systems. Although dairy is the main source of calcium, those eliminating it from their diet should turn to other equally valuable sources of this element, such as sesame, tofu, almonds and green leafy vegetables. It is also important to ensure the proper absorption of calcium, which can be supported by ingredients such as vitamin D, magnesium, xylitol or erythritol. If deficiencies are identified, calcium supplementation is worth considering, but only under the guidance of a doctor.
