Bones have some calcium, but the calcium in bones is not easily dissolved in the soup, and the calcium content of the simmered bone soup is low, which can not meet the needs of calcium supplementation. Even if more bones are put in the soup and the boiling time is extended, the calcium concentration will not exceed 4mg/100ml, so the effect of drinking bone soup is not obvious. It is recommended that if people who need calcium supplementation want to do so by drinking bone broth, they can add some soybeans, seafood and other calcium-rich foods together during the boiling process to increase the effectiveness of calcium supplementation. In daily life, we can also supplement calcium by properly consuming dairy products, eggs, fish, sesame seeds, and calcium-containing vegetables such as cauliflower, broccoli, and kale. Among them, the concentration of calcium in milk is 100mg/100ml, which is tens of times more than bone broth and can better replenish the body’s calcium. In the calcium supplementation, you also need to do more outdoor exercise, more sunshine, and vitamin D supplementation, which is conducive to calcium absorption. If calcium deficiency is serious, oral calcium supplements, such as calcium gluconate, calcium carbonate, etc., can also be taken under the guidance of a doctor for treatment if necessary.
