An evidence-based explainer
How to grow taller faster? The honest answer.
Nothing reliably makes a healthy person grow taller faster. No exercise, stretch, supplement or device has been shown to add height once the growth plates in your bones have closed. Most of your height comes from your genes; good food, sleep and health care during childhood help you reach it, not exceed it.
If you are worried about a child's growth, talk to a paediatrician or family doctor. That is where real answers, and any real treatment, come from.
The answer depends on who is asking
-
If you are an adult
Your height is set
Once growth has finished in adolescence, the growth plates close and turn to solid bone. There is nothing left to lengthen. Products promising otherwise are not backed by health or regulatory agencies.
-
If you are still growing
Look after the basics
Enough sleep, a varied diet and daily activity support normal growth. They help you reach the height your genes allow; they do not push past it. Your growth spurt comes with puberty, on your body's timetable.
-
If you are a parent
Watch the pattern, ask the doctor
A child who keeps to their own line on a growth chart is usually doing fine, even if that line is low. Slowed growth, very early or late puberty, or a big gap from peers are reasons to see a paediatrician.

About "height increase" products
Why the promises do not add up
There is a whole market of pills, powders, sprays, stretching programmes and devices sold as ways to grow taller, often with a promised number of centimetres. This site names no products or brands. It looks at the category as a whole, and the problem is the same across it: height comes from bone growth at the growth plates, and none of the agencies this site relies on describes any of these products as able to lengthen bone.
Dietary supplements do not go through the testing that medicines do, and the U.S. Food and Drug Administration warns that promised outcomes, quick fixes and personal success stories are classic signs of health fraud.

Where to start
Start with the one fact that settles most questions
Height comes from growth plates near the ends of the long bones. They work through childhood and the teenage growth spurt, then close. Once you know that, most claims about growing taller are easy to judge.
