The human body’s demand for calcium reaches its peak at night and shows a trough in calcium content in the early morning and before bedtime. It is recommended to choose to take it during or after dinner as the best choice for better absorption of calcium tablets. Usually calcium tablets taken on an empty stomach cannot be fully decomposed and do not achieve the preset effect, while calcium tablets are fully absorbed and utilized when they are decomposed into calcium ions under the action of gastric acid. Since the secretion of stomach acid increases during meals, it is recommended to take them during or after meals. In addition, calcium tablets are alkaline, so taking them during or after a meal can neutralize stomach acid and reduce the effect of stomach acid on gastric mucous membrane stimulation, while accelerating the absorption of calcium tablets. Calcium supplements need to be taken in the right amount, too much may cause stones, it is recommended that you can also eat food containing more calcium, such as milk, soy products, etc.. At the same time, strengthen outdoor exercise, more sunshine, to promote the absorption of calcium.
