Do we still need to eat calcium when eating AD and D3

Whether additional calcium supplementation is needed after supplementing with vitamin AD and vitamin D3 should be determined based on dietary intake. Vitamin D helps promote calcium absorption, but if the daily diet already contains sufficient calcium, there is no need for additional supplementation. Common high calcium foods include milk, tofu, green leafy vegetables, etc. Special populations such as those lacking sunlight or lactose intolerance can adjust their supplementation plan under the guidance of a doctor. The core function of vitamin AD and vitamin D3 is to regulate calcium and phosphorus metabolism, with vitamin D3 increasing calcium absorption by activating intestinal calcium binding proteins. When there is sufficient calcium intake in the diet, such as drinking 300 milliliters of milk, consuming 100 grams of tofu or 200 grams of rapeseed per day, it can basically meet the daily calcium requirement of 800 milligrams for adults. Extra calcium supplementation at this time may lead to excessive intake, causing gastrointestinal discomfort or increasing the risk of kidney stones.

For populations at significant risk of calcium deficiency, such as pregnant women, postmenopausal women, or adolescents in the rapid growth stage, if dietary surveys show a daily calcium intake of less than 600 milligrams, combined supplementation is necessary while monitoring blood calcium levels. Long term use of antiepileptic drugs or glucocorticoids may interfere with vitamin D activation, and calcium dosage should also be adjusted according to medical advice.

It is recommended to prioritize calcium supplementation through dietary assessment, with a daily intake of 300 grams of dairy products, 50 grams of nuts, and dark green vegetables. During the calcium supplementation period, it is necessary to regularly monitor serum and urine calcium levels to avoid consuming large amounts of spinach, amaranth, and other vegetables with high oxalic acid content that can affect absorption. Patients with special diseases should have their bone metabolism indicators rechecked every 3 months and adjust their nutrient supplementation plan dynamically based on the results.
