Safety is another concern with weight loss pills, as some contain unregulated or stimulant-based ingredients like caffeine, green tea extract, or even laxatives. Overuse can lead to side effects such as jitters, digestive issues, or heart complications. The FDA does not strictly monitor dietary supplements, meaning some products may make exaggerated claims without proper evidence. Consumers should consult a doctor before trying any keto diet supplements, especially if they have underlying health conditions or take prescription medications.
