1. Excessive calcium supplementation will increase the risk of osteoporosis. Studies in western developed countries have found that calcium can not effectively reduce the incidence of osteoporotic fractures. On the contrary, the risk of hip fracture increases by 50% after osteoporosis patients take high calcium.

Eating calcium tablets is an effective way to supplement calcium, but eating too many calcium tablets is harmful. What about eating too many calcium tablets? Taking calcium tablets every day should not exceed 2000mg. What happens when you eat too many calcium tablets? The following small series introduces you.
What happens when you eat too many calcium tablets?
Excessive calcium supplementation is harmful to health, such as calcium supplementation exceeding 2000 ~ 2500 mg per day, which may lead to renal function damage and adverse reactions. The main hazards are as follows:
1. Excessive calcium supplementation will increase the risk of osteoporosis. Studies in western developed countries have found that calcium can not effectively reduce the incidence of osteoporotic fractures. On the contrary, the risk of hip fracture increases by 50% after osteoporosis patients take high calcium.
2. Excessive calcium supplementation will increase the risk of lithiasis. Calcium is not so easily absorbed by the human body. If you ingest too much but can't absorb it, and ingest oxalic acid (such as spinach) at the same time, calcium oxalate stones may be formed after combination. Larger stones can not be excreted with urine, which may cause renal colic, and in severe cases, renal damage.
3. Excessive calcium supplementation will increase the risk of heart injury. Excessive calcium supplementation may lead to an increase in blood calcium content. Hypercalcemia will accelerate the formation of deposits in arteries, lead to ectopic calcification, and eventually accelerate the formation of heart disease due to atherosclerosis.
4. Excessive calcium supplementation affects mineral absorption. The nutrients in the human body need to be in a stable and balanced state, which is conducive to mutual promotion and absorption, otherwise it will be the opposite. Experiments show that high calcium supplementation can obviously inhibit the absorption of iron, zinc, magnesium and phosphorus.
5, hypercalcemia. Early manifestations of hypercalcemia include severe constipation, progressive dry mouth, persistent headache, loss of appetite, irritability, depression, metallic taste in the mouth and weakness. Late manifestations include drowsiness, confusion, hypertension, arrhythmia, nausea and vomiting, and increased urine output. It can be seen that any drug must be divided into two parts and cannot be taken lightly.
6, gastrointestinal adverse reactions. Excessive calcium supplementation can stimulate gastric mucosa, promote gastric acid secretion rebound, lead to a large number of gastric acid and gastric juice secretion, and can cause mucosal congestion and swelling, mucosal erosion or ulcer. Excessive calcium supplementation can also induce constipation, which has a negative impact on health.
