TruHeight: can a supplement make a child taller?

Its own pilot: 0.7 cm in six months, in 28 children. The big independent trial: no difference.

TruHeight sells gummies, shakes and now “growth electrolytes” for children and teens. Short answer: its “32.63% more growth” is 2.94 cm against 2.23 cm over six months, in a company pilot of its shake that 28 children finished — not something we could find in a journal. The best independent evidence points the other way: three years of vitamin D in 8,851 school children who were short of it did not change their height.

Its “32.63% more growth” is 2.94 cm against 2.23 cm over six months, in a company pilot of its shake that 28 children finished and that we could not find in a journal. Nothing we found shows a supplement adds height to a child who is not short of something.
- Company's own material, 28 people (2023) — primary outcome: improved. Funded by the manufacturer. Not counted toward the grade.
Vitamin D makes children grow tallerNo real evidence
In 8,851 school children, almost all short of vitamin D, three years of weekly vitamin D fixed their levels but did not change their height. (A secondary analysis of a larger trial — which is why the grade here is not “tested”.)
- Double-blind randomized trial, 8,851 people, 156 weeks (2023) — secondary outcome: no difference from placebo. Funded by independent sources.

If you are worried about a child’s height

A paediatrician can plot their growth over time against a growth chart — that, not a supplement, is how a real growth problem is found.
