Yaowa Quiz | Is it better to take calcium tablets before meals?

The ingredients of calcium tablets are divided into inorganic calcium and organic calcium. Inorganic calcium is usually calcium carbonate and must be taken after meals. This is because calcium carbonate can only be decomposed into calcium ions that can be absorbed by the human body under the action of gastric acid. Gastric acid secretion increases after eating, and this type of calcium tablet is easier to decompose and absorb. At the same time, taking it after meals can reduce the irritation of calcium carbonate to the gastrointestinal mucosa. Organic calcium includes calcium lactate, calcium citrate, calcium gluconate, etc., which can be absorbed by the human body without the participation of gastric acid. In theory, it can be taken before or after meals. However, according to the characteristics of human metabolism, the calcium content in the body is at a low value at night, and the absorption of calcium is at a peak. Therefore, organic calcium is better absorbed when taken before bedtime. In summary, calcium carbonate is best taken within 1 hour after dinner and organic calcium is best taken before bedtime.
