Nutrition information
Calcium
Calcium is a mineral used to build and maintain bones and teeth and to support muscle contraction, nerve signalling, and other body functions. Food is one way to obtain it; personal needs vary with age and health.
Supplement caution: Calcium supplements are not appropriate for everyone and can interact with medicines. Discuss your diet, health history, and total intake with a clinician or pharmacist before starting one.
Food sources
Sources include dairy products, calcium-set tofu, some leafy greens, canned fish with edible bones, and fortified plant drinks or cereals. Calcium content varies, so check product labels. A varied diet can help provide calcium alongside other nutrients important for bone health.
Bone health is more than calcium
Bone health is influenced by multiple factors, including age, physical activity, overall diet, vitamin D status, hormones, medicines, and medical conditions. Taking extra calcium does not by itself diagnose or treat osteoporosis. If you have fracture concerns or risk factors, ask a healthcare professional about appropriate assessment.
Supplements and interactions
Large supplemental amounts may cause side effects and can affect absorption of certain medicines. If supplementation is recommended, a professional can help choose a suitable amount and timing based on diet and medication schedule. Do not replace prescribed treatment with a supplement or a historical homeopathic reference.
