Calcium tablets available for menopause include calcium gluconate tablets, calcium carbonate tablets, calcium citrate tablets, etc. However, the specific efficacy varies from person to person and it is impossible to say what is the best and most effective. 1. Calcium gluconate tablets: traditional calcium supplements, but the calcium content is lower than other new drugs, which are less used now. This drug is contraindicated in hypercalcemia, hypercalciuria, calcium-containing kidney stones or people with a history of kidney stones, and there may be constipation and other adverse reactions during the use of the drug. 2. Calcium carbonate tablets: at present, it is commonly used as a compound preparation with vitamin D3, i.e. calcium carbonate D3 tablets, in which vitamin D3 can promote calcium absorption. The contraindications of this drug are the same as above, and the adverse reactions include belching (burping), constipation, and rebound increase in gastric acid secretion. 3. Calcium citrate tablets: especially suitable for those who cannot fully digest and absorb calcium carbonate preparation due to the existence of digestive system diseases and low gastric acid secretion. The contraindications of this drug are the same as above, and constipation is occasionally seen as an adverse reaction. However, it should be noted that the therapeutic effect of the above calcium tablets may be affected by individual’s physical condition, the severity of calcium deficiency and other factors, and the specific therapeutic effect may have individual differences, and there is no so-called “the best and the most effective” calcium tablets for all menopausal people. There is no such thing as the “best and most effective” calcium tablet for all menopausal people. Besides the above calcium tablets, there are other calcium supplements available. Therefore, people who need to use calcium tablets during menopause should choose and take the medication under the guidance of a doctor, and should not blindly use the medication on their own, in order to avoid adverse consequences.
