It is common to want to maximize results by taking multiple supplements, but caution is necessary during a diet program. While combining them may provide psychological reassurance or fill specific nutritional gaps (such as vitamins), there are clear drawbacks. First, stimulants or caffeine in supplements can synergize with the metabolism-boosting effects of herbal medicine, potentially worsening heart palpitations or insomnia. Second, certain ingredients may inhibit the absorption of the herbal medicine, reducing its overall effectiveness. From a Traditional Korean Medicine (TKM) perspective, metabolic stagnation is often caused by the accumulation of Dam-eum (痰飮, phlegm-fluid) or Eohyeol (瘀血, blood stasis). For those with Bi-heo (脾虛, Spleen deficiency or weakened digestive function), overloading the system with various supplements can lead to gastrointestinal distress. Ultimately, the answer depends on your current physiological state. I am not suggesting you stop everything immediately; instead, please provide a list of the products you are taking during your visit. I will analyze the ingredients to distinguish between what is safe to continue and what should be temporarily paused.
