I used to try every trending supplement myself, but I soon realized that while some made me feel great, others caused bloating and discomfort. This experience taught me a fundamental truth: the right choice depends entirely on the individual and their current health status. On the positive side, probiotics cultivate a healthy gut microbiome, which can lower systemic inflammation and enhance the basic metabolic capacity of the body. They are particularly beneficial for those struggling with sluggish bowel movements. However, there are important caveats, specifically regarding 'constitution' (Sasang/Chejil). In Traditional Korean Medicine, if a patient suffers from 'Spleen Deficiency' (Bi-heo, 脾虛)—a state where the digestive functions are severely weakened—taking high doses of probiotics blindly can actually worsen indigestion. It is crucial to remember that probiotics are 'supplements,' not 'cures.' While I recommend them as an added boost when a healthy diet and lifestyle are already in place, they have limitations if there are root causes blocking your metabolism, such as 'Dam-eum' (痰飮, accumulation of metabolic waste/phlegm) or 'Eo-hyeol' (瘀血, blood stasis). I suggest first evaluating your digestive capacity and identifying why your metabolism has slowed down. I would be happy to help you analyze your specific constitution to find the best approach.
