Hello, don't take medicine before your period. The ingredients of diet pills mainly contain some laxatives or appetite suppressants. When menstruation comes, the body's immunity is the lowest, and eating diet pills can easily cause malnutrition or other diseases. Through the deep conditioning of fat-controlling components, Jianting transforms human body constitution into a "balanced body constitution" in which energy intake and consumption are balanced. Fat is difficult to synthesize and store, thus completely solving the obesity problem and never rebounding! I wish you success in slimming!
