Thanks for the query. I would personally recommend you not to go for any market product, as it may have side effects like hormonal imbalance. some of the natural ways are- Proper Sleep, Regular Exercise, Sports, Yoga. Maintaining the Correct Posture, Balanced Diet. Vitamin D and proteins help in triggering the growth hormones, and are required for proper growth of teeth and bones.Taking drugs and alcohol at a young age can be extremely harmful. Most available data indicate that calcium intake levels of about 800 mg/d are associated with adequate bone mineral accumulation in prepubertal children. Hope this helps you.
