Can I eat waxberry after taking calcium, iron, and zinc supplements?

Generally speaking, it is acceptable to eat Chinese bayberry (Myrica rubra) after taking calcium, iron, and zinc supplements, but attention should be paid to the time interval. Detailed explanation is as follows:

The metal ions contained in calcium, iron, and zinc supplements may bind with tannic acid present in bayberries, affecting the absorption efficiency. If bayberries are consumed immediately after taking calcium, iron, and zinc supplements, tannic acid may rapidly bind with the metal ions, thereby reducing nutrient absorption rates. It is therefore recommended to wait 1-2 hours after taking the supplements before consuming bayberries, allowing the supplements to be partially absorbed first and minimizing potential interactions.

If sufficient time has passed after taking calcium, iron, and zinc supplements—for example, more than 1.5 hours—by which time the supplements have been partially absorbed by the body, consuming bayberries will have minimal impact on nutrient absorption. Moreover, bayberries are rich in vitamin C, and moderate consumption can promote iron absorption. In such cases, properly scheduling the time of consumption allows one to enjoy the fruit while ensuring adequate nutrient intake.

While taking calcium, iron, and zinc supplements, besides maintaining an interval with bayberry consumption, one should also avoid simultaneously consuming beverages containing tannic acid, such as strong tea and coffee. In terms of diet, combining supplement intake with foods rich in vitamin C may help enhance nutrient absorption. Additionally, attention should be paid to the dosage of various nutritional supplements, and supplementation should be conducted following medical advice.
