When is the best time to supplement calcium?

Patient's question:

Before the age of 8, the child did not grow much in height. Later, they were given calcium supplements for a year, and now they have grown significantly taller. However, they don't want to keep giving him calcium pills, fearing side effects. They are wondering whether to take it once a day, and if it's better to take it in the morning or at night.
Previous treatment and effectiveness: Should be given once a day...

Doctor's answer:

The best time to take calcium supplements is after dinner or before going to bed. Calcium is most easily digested in the evening, so it is generally recommended to take calcium supplements after having dinner. However, taking calcium supplements does not mean that the calcium is fully digested, because sodium in the body is the main culprit causing calcium depletion. Therefore, it is important to consume sufficient salt (sodium chloride)—5 grams per day is sufficient for most people, but those with a preference for stronger flavors should be cautious! Additionally, magnesium enhances calcium absorption, so supplementing with calcium without magnesium is ineffective. Many foods are rich in magnesium, such as meat, seafood, vegetables, and more.
Regarding physical activity, the best time is between 4 PM and 7 PM in the evening, rather than early to bed and early to rise. Also, get some sun exposure when appropriate. A few more reminders: when taking calcium, don’t forget to drink plenty of water! If you want to grow taller, pay attention to your diet, physical activity, and deep sleep. To increase height, you should consume more protein, especially foods rich in essential amino acids, such as: flour, wheat germ, beans, shrimp, crabs, shellfish, seaweed, beef, chicken, liver, pork leg meat, eggs, milk, cheese, and dark-colored vegetables. Activities that stimulate appetite, promote sleep, and apply moderate horizontal pressure to the bones are beneficial for growth. Specifically, these include running, jumping rope, singing and dancing, playing basketball, and playing volleyball.
Health Tips: The absorption of calcium is affected by dietary oxalates and phytates, as they can combine with calcium to form insoluble salts. Grains contain high levels of phytates, while certain vegetables like amaranth, spinach, and bamboo shoots are rich in oxalates. Dietary fiber can also impact calcium absorption. When supplementing with calcium, it is best to consume foods rich in calcium from natural sources as much as possible. Food is the best medicine, with no side effects and is relatively safe. I hope my explanation helps you!
