The demand for immune-boosting supplements has surged, driven by concerns about COVID-19, diabetes, and other infectious diseases. Particularly popular are supplements targeting respiratory health. In addition, the trend of stress, sleep, and mental health support has gained momentum, with consumers seeking convenient solutions to enhance mood and overall well-being. This has resulted in a demand for supplements that address these concerns.

Consumers are increasingly engaging themselves in healthy behavior, such as exercising regularly and incorporating a healthy diet, resulting in high penetration of dietary supplements.
