For a 38-year-old female, routine
calcium supplementation is not automatically required unless dietary intake is low or there is deficiency if needed, 500 mg elemental calcium per day with
vitamin D is usually sufficient it should be taken after meals, not randomly. excess calcium without need can cause side effects, so supplements are best taken based on diet, symptoms, or blood tests.
If there is bone pain, weakness, or low vitamin D, testing and medical advice are recommended.
