Height Barhane Ka Tarika: Growth Plates, Sleep and Real Nutrition
A neighbour’s aunty swears by a jar of ground almonds and ashwagandha powder that promised her son three extra inches before his cousin’s wedding. He is nineteen now, still the same height, and the jar is still half full in the kitchen cupboard.
Before you start
- Growth plates: close on their own timeline, usually late teens for girls and early twenties for boys.
- Powders and syrups: cannot reopen a closed growth plate. None of them.
- What actually matters: protein, sleep, calcium, sunlight, and posture during the years the plates are still open.
- See a doctor if: a teen is far shorter than both parents, or growth has clearly stalled before age 14 to 15.

Height is decided mostly by genes and by what happens at the ends of the long bones, in areas called growth plates or epiphyseal plates. These are strips of cartilage near the ends of bones like the femur and tibia. As long as they are open, the bone can lengthen. Hormones, mainly growth hormone and the sex hormones that arrive with puberty, drive this lengthening for a window of years. Once the plates fuse into solid bone, that particular growth is over. No cream, tea, capsule or stretching machine can restart it. This is basic physiology, not opinion, and any seller telling you otherwise is selling a story.
What decides how tall someone ends up
Genetics sets the range. A rough, commonly used estimate for a child’s likely adult height averages the two parents’ heights and adjusts a little up for boys and down for girls, then allows a spread of several centimetres either side. Within that genetic range, though, nutrition and health during childhood and the growth spurt of puberty decide whether a person reaches the top or the bottom of it. Chronic illness, poor diet, and severe long-term stress during childhood can shave real centimetres off final height. This is where a family actually has some influence, not in the years right before a wedding when the plates are already closing.
Protein, calcium and the nutrients that matter
Bone is not just calcium. It needs a steady supply of protein for the collagen scaffold, calcium and phosphorus for hardness, vitamin D to help the body absorb that calcium, and vitamin K and zinc in smaller amounts. A teenager who is growing needs noticeably more protein and calcium than an adult of the same weight.
- Protein: roughly 1 to 1.2 grams per kilogram of body weight per day for an actively growing teen, spread across meals rather than dumped into one shake. Dal, eggs, chicken, fish, paneer, and milk all count.
- Calcium: about 1,300 mg a day for 9 to 18 year olds, which is close to 3 to 4 cups of milk or its equivalent in yoghurt, paneer, and leafy greens like sarson or methi.
- Vitamin D: 15 to 20 minutes of midday sun on the arms and face, several times a week, plus fortified milk or egg yolk, since deficiency is common in cities with heavy pollution and long indoor hours.
Sleep does more than any powder
Growth hormone is released mainly in pulses during deep sleep, particularly in the first few hours of the night. A teenager who sleeps five or six hours a night, chasing exams or a phone screen, is cutting into exactly the window where this hormone does its work. Sleep specialists generally recommend 8 to 10 hours a night for teenagers, not the 6 to 7 hours that has become normal.
- Fix a wind-down time 30 minutes before bed: phone away, lights dimmed.
- Aim for lights-out by 10.30 pm to 11 pm on school nights, giving room for 8.5 to 9.5 hours before a 7 am wake-up.
- Keep the room cool and dark; a fan or light-blocking curtain helps more than any supplement.
- Keep weekend sleep within an hour of the weekday schedule, since swinging wildly disrupts the hormone rhythm.
Posture: the free centimetre most people ignore
Slouching does not stop bones from growing, but it compresses the spine’s natural curve and can make a person look, and even measure, shorter than their actual bone length by a centimetre or two. Years of hunching over a phone or a low desk make this worse. Simple daily habits (standing tall with shoulders back, stretching the chest and hip flexors, strengthening the back muscles with rows or planks) will not add bone length but will let a teen present their full height honestly.
Myth: powders, syrups and “height increasing” capsules
Myth: a herbal powder, a syrup with ashwagandha and shatavari, or a capsule sold online can add inches after age 15 or 16. Reality: these products have never been shown to lengthen bone in a person whose growth plates are still open, let alone one whose plates have already fused. What they sometimes contain is a mix of protein, minerals and mild stimulants, which might slightly improve appetite or energy, nothing more. If a teenager is genuinely undernourished, fixing the diet will help; the powder itself is not doing anything a bowl of dal, egg and milk would not do better and cheaper.
In older Unani thinking, poor growth in a child was often linked to weak digestion (daur-e-hazm) failing to convert food into proper nourishment, so treatment focused on strengthening appetite and digestion with things like chosen tonics, rather than on the bone itself. Seen today, this maps loosely onto the real idea that undernutrition during growth years genuinely does limit height. It is worth knowing as tradition, not as a mechanism for adding height beyond a person’s natural ceiling.
When to actually see a doctor
Most teens who are “short” are simply on the shorter end of a normal family pattern. A doctor visit is worth it when growth has clearly stalled, when a child is far outside the range you would expect from both parents, when puberty has not started by 14 in girls or 15 in boys, or when height is combined with other symptoms like extreme fatigue, headaches, or vision changes. A paediatrician or endocrinologist can plot growth on a proper chart over time and check hormone levels if needed; a single measurement tells you very little.
Do not give a child or teenager any unregulated “height growth” injection, hormone product, or imported capsule bought online. Growth hormone is a prescription medicine with real risks when misused, including joint and metabolic problems, and should only ever be given under a specialist’s supervision after proper testing. If your teen seems anxious or distressed about their height, that emotional side deserves attention on its own, separate from any nutrition plan. Talk to a doctor before starting any supplement in a child who has an existing kidney, liver, or hormonal condition.
Try this
Instead of a jar of powder, put a glass of milk and a boiled egg on the breakfast table every single day for a month, and move bedtime 45 minutes earlier. It costs less. It is the one intervention with an actual mechanism behind it, because it addresses the two levers, protein availability and the deep sleep window in which growth hormone is actually released, that genuinely influence how close a growing teenager gets to their full genetic height potential, rather than promising to override that potential entirely.
Height, growth plates and teens
Can height be increased after 18?
Once the growth plates have fused, bone can’t get any longer, and for most people that has happened by the late teens or early twenties. After that, better posture can let you stand at your true height, which may look a centimetre or two taller, but no food, powder or exercise adds real length.
At what age do growth plates close?
In girls they usually close in the mid to late teens, and in boys from the late teens into the early twenties. The range is wide, and early or late puberty shifts it. If it genuinely matters medically, a doctor can check with a hand or knee X-ray.
Do height increase powders and capsules really work?
No. None of them can reopen a closed growth plate, and they haven’t been shown to add bone length even while the plates are open. Most contain protein, minerals and sometimes mild stimulants. A bowl of dal, an egg and a glass of milk do the same job for much less money.
Which foods help a teenager grow taller?
Foods that supply protein, calcium and vitamin D: milk, dahi, paneer, eggs, dal, chicken, fish, and greens like sarson and methi. They can’t push height past the genetic range, but a teen who eats well is more likely to reach the top of it. Spread protein across meals rather than one big shake.
How much sleep does a growing teenager need?
Around 8 to 10 hours a night. Growth hormone is released mostly during deep sleep in the first part of the night, so late nights with a phone or exam prep cut into that window. A lights-out around 10.30 to 11 pm and a steady weekend schedule help most.
Can exercise or stretching make a teenager taller?
Exercise keeps bones strong and posture good, but no stretching routine lengthens bone beyond its genetic limit. Basketball and swimming get credit for tall players mostly because tall kids are drawn to those sports. Keep teens active for health, not as a height trick.
Does hanging from a bar increase height?
Only for a short while. Hanging decompresses the spine, much like how you’re slightly taller in the morning than at night, and it settles back within hours. It doesn’t add permanent bone length.
Is ashwagandha good for height?
There’s no good evidence that ashwagandha adds height, and it isn’t a herb to give children or teens casually. Height products mixing it with shatavari or other herbs rely on marketing, not results. If a teen isn’t eating well, fixing meals is the useful step.
Are growth hormone injections safe for increasing height?
Only when a specialist prescribes them after proper testing shows a real need. Growth hormone is a prescription medicine with risks, including joint and metabolic problems, when it’s misused. Never buy height injections, hormones or imported capsules online for a child.
When should I take my child to a doctor about height?
See a paediatrician if growth has clearly stalled, if your child is far shorter than you’d expect from both parents, or if puberty hasn’t started by 14 in girls or 15 in boys. Also go sooner if short stature comes with ongoing tiredness, headaches or vision changes. The doctor will track growth on a chart over months, not judge from one measurement.
How can I predict my child’s adult height?
A rough guide averages both parents’ heights, then adjusts a little upward for boys and downward for girls, with several centimetres either way. It’s an estimate, not a promise. Nutrition, sleep and health during childhood decide whether a child ends up near the top or bottom of that range.
Can a lactose-intolerant teen still get enough calcium?
Yes. Milk is handy, not essential. Dahi is often easier to tolerate, and paneer, ragi, til (sesame), and leafy greens like sarson and methi all add calcium. A doctor can advise if the diet still falls short.
Does bad posture make you shorter?
It doesn’t stop bones growing, but slouching squeezes the spine’s curve and can make someone look and even measure a centimetre or two shorter. Chest and hip stretches, and back work like rows and planks, help a teen stand at their full height.
Does vitamin D matter for height?
It matters for bone, because the body needs vitamin D to absorb calcium. Short spells of midday sun on the face and arms several times a week, plus egg yolk and fortified milk, cover most needs. Deficiency is common in teens who stay indoors a lot, and a doctor can test for it.
Can stress or illness affect a child’s height?
Long-term illness, poor diet and severe ongoing stress in childhood can lower final height by real centimetres. A short bout of flu won’t. If a child is often unwell or struggling to eat, that’s worth sorting out with a doctor during the growing years.
My teenager is upset about being short. What can I do?
Take the feelings seriously on their own, separate from any diet plan. Reassure them that most short teens simply follow their family’s pattern, and that late bloomers often keep growing after friends stop. If the worry is affecting mood, school or eating, speak to a doctor about it.
See a doctor before trying any product marketed for height, and talk to a paediatrician if a teenager’s growth pattern worries you rather than relying on a totka. Read more in our Desi Remedies section, and see our related piece on how much turmeric is safe to give growing children.
