You can prevent most gastrointestinal disorders simply by avoiding an empty stomach for ingredients that have high acidity or directly irritate the gastric mucosa\u2014such as vitamin C, iron supplements, and zinc\u2014and by consuming fat-soluble supplements with meals containing fat components.
\nThe core of supplement intake lies not in unconditional “empty-stomach consumption” or copying others, but in the “right timing” tailored to your stomach’s condition and the characteristics of each ingredient. Based on the information shared today, check the intake times that suit your body. Through just a small change in habits, you will be able to take care of true health comfortably and safely without worrying about heartburn.
