There's no one-size-fits-all answer to this question, as the best weight loss supplement for someone on TikTok will vary depending on their individual goals and needs. However, some popular options for supplements that can aid in weight loss include green tea extract, garcinia cambogia, and Forskolin. These ingredients are thought to boost metabolism, reduce appetite, and promote fat burning - all of which can lead to successful weight loss results. If you're looking for a little extra help achieving your weight loss goals, consider incorporating one (or more!) of these supplements into your routine.
