It is not recommended to take calcium tablets immediately after drinking alcohol, but after an interval of 3 to 4 hours. Wine contains alcohol, which may affect the absorption function of the gastrointestinal tract, and if you take calcium tablets immediately after drinking wine, it may affect the body’s absorption of calcium, thus reducing the efficacy of calcium tablets. Moreover, drinking alcohol may also trigger allergic reactions in the body. If one’s metabolism is relatively fast and the amount of alcohol consumed is relatively small, one can take calcium tablets after an interval of about 3 to 4 hours after drinking alcohol. If the body’s metabolism is slow, the amount of alcohol consumed is large, or the body has a severe reaction to intoxication, it is necessary to wait until the alcohol in the body has been completely metabolized before taking calcium tablets. When taking calcium tablets, it is also important to take supplements under the guidance of a doctor; if there is no calcium deficiency in the body, no additional supplements are needed.
