For healthy growth and weight gain, traditional herbs like Ashwagandha and Shatavari are highly beneficial. Ashwagandha helps improve muscle mass and strength, while Shatavari supports digestion and healthy weight gain. However, please note that height is primarily determined by genetics, and natural growth stops once your bone growth plates fuse (usually around 18 to 21 years of age). No medicine can increase height after this period. To support your body's development, focus on a balanced, protein-rich diet, regular stretching exercises, and 8 hours of sleep. Consult a healthcare provider before starting any supplements.
