Nevertheless, increasing the dosage to more than 1000 mg is not associated with rapid relief of this condition.
Preventing tooth loss in the elderly

Children’s calcium benefits
In particular, calcium consumption during adolescence helps reduce the risk of osteoporosis and osteoporosis. During adolescence, most of the body’s bones grow.

Those with low stomach acid levels, or those who have lost stomach acid. Due to calcium absorption being lower with an empty stomach, calcium tablets are recommended to be taken with food to maximize absorption.
Those with high blood phosphate levels or low blood levels; Since there is a balance between calcium and phosphate in the body, consuming too much calcium may cause harm, so a doctor should be consulted before consuming this amount of calcium.

A group of antibiotics called quinolones, which include ciprofloxacin, levofloxacin, and ofloxacin. Calcium can reduce the body’s ability to absorb quinolones, which may reduce their effectiveness, so quinolone two should be used instead.
The absorption and effect of bisphosphonates in the body can be reduced if calcium is taken 30 minutes before bisphosphonates.
It is similar to vitamin D, which helps the body absorb calcium, so taking calcipotriol with calcium can cause a significant increase in calcium levels.
A digoxin is a drug that increases the strength of the heartbeat, and calcium can affect the heart, and its use with this drug may cause irregular heartbeats, so it is recommended to consult a doctor before taking both at the same time.
