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.
Can exercise or stretching make a teenager taller?
Exercise supports healthy bone density and posture, and swimming or basketball is often credited with tall players, but that is partly selection, tall kids gravitate to those sports. No stretching routine lengthens bone beyond its genetic ceiling.
Does hanging from a bar help height?
It can decompress the spine briefly and make a person stand a touch taller for a short while, similar to how people are slightly taller in the morning than at night, but it does not add permanent bone length.
At what age do growth plates usually close?
Roughly 14 to 16 in girls and 16 to 18 in boys on average, though there is a wide normal range and a doctor can check with an X-ray if it genuinely matters medically.
Is milk essential, or can a lactose-intolerant teen still grow well?
Milk is a convenient source, not the only one. Paneer, yoghurt, ragi, sesame seeds (til), and leafy greens can cover calcium needs for a teen who cannot tolerate milk.
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.
