Men usually stop growing by the age of 25 and women by 21. This happens shortly after puberty. Growth hormones produced by the pituitary glands are responsible for the growth of our tissues, cells, muscles and bones.

Instead of opting for height increase supplements or pills, amino acid, protein and vitamin supplements, it is always safer to adopt natural ways and methods to grow tall. 

Certain anaerobic and stretching exercises will help your body induce growth hormone. It is sleep and exercise that initiates the production of growth hormone more than any supplements or pills do. Swimming and cycling is considered to be best for height increase.

Growth hormone secretion is mainly due to the balance between nitric oxide and lactate. Exercise for a minimum of 10 minutes with great intensity to build enough lactate that will activate the growth hormone secretion even after one stops exercising.

Sleep in the right posture to lengthen your spine and increase your height. Sleep on a firm mattress. Sleeping on a hard surface will provide the right alignment to your spine. While sleeping, keep your legs and knees raised slightly. Sleep on your back and do not sleep face down.
