Selecting weight loss products requires a strategic balance between efficacy, safety, and market demand. Buyers should categorize products into dietary supplements (capsules, powders), functional foods (meal replacement shakes, keto snacks), and fitness equipment. For supplements, prioritize natural ingredients like green tea extract or fiber-based appetite suppressants. Ensure all functional foods meet nutritional labeling standards and offer a shelf life of at least 12-18 months to account for cross-border transit and inventory turnover.
