TruHeight’s own clinical trial uses a six-month timeline to measure changes in height, which is the most concrete answer available. The company recommends consistent daily use for at least three to six months before evaluating results, and body composition changes are tracked as early as three months into supplementation. But whether the product works at all depends heavily on one biological factor: whether your growth plates are still open.
What the Clinical Trial Measures
TruHeight has a registered clinical trial on ClinicalTrials.gov that tests its oral supplement on children over a six-month period, taken once daily, five days per week. The primary outcome is straightforward: the difference in height from the start of the study to the end at six months. A secondary measure looks at a specific collagen marker in urine (a sign of active bone growth) at the same six-month mark, while body composition is checked at both three months and six months.
This trial has not yet published results, so there is no independent, peer-reviewed data confirming how much height, if any, participants actually gained. The six-month window tells you how long the company itself believes it takes to see measurable changes, but it does not guarantee those changes will happen.
Growth Plates Determine Everything
No supplement can increase height once your growth plates have closed. These cartilage zones at the ends of long bones are what allow bones to lengthen during childhood and adolescence. Once they harden into solid bone, height gains from any nutritional intervention become biologically impossible.
Growth plates typically close between ages 13 and 15 for girls and 15 and 17 for boys, though this varies. If you’re an adult whose growth plates have already fused, taking TruHeight for six months or six years won’t add height. A simple X-ray of the hand or wrist can confirm whether your growth plates are still open, and that’s the single most important piece of information before spending money on any growth supplement.
What the Ingredients Actually Do
TruHeight contains several ingredients that play supporting roles in bone health, though none of them have been proven to increase height beyond what normal growth would produce in a well-nourished child.
One key ingredient, ashwagandha, has shown some promise in animal studies. In juvenile rats with thyroid-related growth problems, ashwagandha extract helped restore growth plate thickness from severely reduced levels back toward normal. The effect appeared tied to improving thyroid hormone levels, which growth plate cells are highly sensitive to. But this was a study on animals with a specific hormonal deficiency, not healthy children, and the results don’t translate directly to human height gains.
The supplement also uses a nano-sized form of calcium, which does appear to be absorbed more efficiently than standard calcium. In rat studies, nano-calcium was absorbed at roughly 89% compared to about 64% for regular fortified calcium, and its bioavailability (the amount your body actually uses) was nearly 42% versus about 25%. Better calcium absorption supports bone mineralization, which is important during growth, but calcium alone doesn’t make bones grow longer. It makes them denser and stronger.
How to Take TruHeight
The recommended dose is two gummies or two capsules per day, taken with your morning and evening meals. The company notes that eating food alongside the supplement improves how well your body absorbs the vitamins and minerals it contains. You can take it on an empty stomach, but pairing it with breakfast and dinner is the better option for nutrient uptake.
Why Sleep Matters More Than You Think
If you’re taking TruHeight for a child or teenager who is still growing, sleep quality may matter as much as anything in the bottle. Growth hormone is released in pulses during deep sleep, with the largest burst occurring shortly after falling asleep during the first episode of slow-wave (deep) sleep. Most growth hormone secretion happens during these deep sleep stages rather than during lighter sleep or dreaming phases.
For a growing child, consistently getting enough deep sleep creates the hormonal environment that actually drives bone lengthening. A supplement can only support what the body is already doing. If a teenager is sleeping five or six hours a night and missing those critical deep sleep windows, even perfect nutrition won’t fully compensate. Prioritizing eight to ten hours of sleep, regular physical activity, and a balanced diet creates the foundation that any supplement would need to build on.
Realistic Expectations
The honest answer is that there is no published clinical evidence showing TruHeight increases height beyond normal growth rates in healthy children. The six-month trial is still underway, and until results are available, the timeline is based on the company’s own recommendations rather than proven outcomes.
If your child’s growth plates are open and they are nutritionally deficient in calcium, vitamin D, or other key nutrients, a well-formulated supplement could theoretically help them reach their genetic height potential. That’s different from growing taller than genetics would otherwise allow. Children who already eat a balanced diet and have no nutritional gaps are unlikely to see additional height from supplementation. For children who are significantly behind on growth curves, a pediatrician can test for actual deficiencies and hormonal issues that have targeted, evidence-based treatments.
