hello friend, kindly note there is no such supplements which increases ones height...all advertisements showing height growing medication or supplements are totally fraud and useless...height of a person totally depends on growth hormone released by pituitary gland..factors that help your growth are your parents or even your forefathers height,environmental condition also plays an important role in determining body development,good diet and nutrition also guides growth... therefore at this juncture i would advice you to go for good protein diet,drink plenty of water and fruit juices ,go for proper exercises under gym trainer...kindly keep away from any such height growing supplements... take care
