TruHeight is not FDA approved. It is classified as a dietary supplement, and the FDA does not approve dietary supplements the way it approves prescription drugs. This distinction matters because it means TruHeight’s claims about increasing height have not been evaluated or verified by any federal health agency before the product hit store shelves.
Why the FDA Doesn’t Approve Supplements
Under the Dietary Supplement Health and Education Act of 1994 (DSHEA), dietary supplements follow a completely different regulatory path than drugs. Pharmaceutical drugs must go through years of clinical trials and receive explicit FDA approval before they can be sold. Supplements do not. Instead, the manufacturer is responsible for evaluating the safety and labeling of its own products before marketing them.
The FDA only steps in after a supplement is already on the market, and only if the product turns out to be adulterated (contaminated or unsafe) or misbranded (making false claims on its label). This means TruHeight, like every other dietary supplement sold in the United States, reached consumers without the FDA independently confirming that it is safe or that it does what it claims to do.
Federal Action Over TruHeight’s Claims
The lack of FDA oversight doesn’t mean supplements can make any claim without consequence. The Federal Trade Commission (FTC) took action against TruHeight, alleging that the company engaged in deceptive and unsubstantiated advertising of its height-enhancing supplements for kids and teens. The FTC’s complaint stated that TruHeight’s growth claims were unsubstantiated because the company lacked competent and reliable scientific evidence to back them up.
Separately, TruHeight (operating as Vanilla Chip, LLC) entered a settlement agreement with the California Attorney General’s office under Proposition 65. That settlement required the company to arrange for independent third-party testing of its products for lead and PFOA contamination at least once a year for three years, using certified laboratories. The fact that this testing was mandated through a legal settlement, rather than being a routine part of production, is worth noting.
What’s Actually in TruHeight
TruHeight’s capsules and gummies share a similar formula. Each two-capsule or two-gummy serving contains 300 mg of calcium, 20 mcg of vitamin D, and a 113 mg proprietary blend. That blend includes ashwagandha root extract, spirulina, two amino acids (L-arginine and L-glutamine), astragalus root extract, and vitamin K2. The capsule version also contains 150 mg of phosphorus.
The calcium and vitamin D are standard nutrients important for bone health, available in countless multivitamins at similar or higher doses. The proprietary blend is where TruHeight’s marketing focuses, but the total amount is only 113 mg, split across six ingredients. Because it’s a proprietary blend, the label doesn’t reveal how much of each ingredient you’re actually getting. If the six ingredients were divided equally, each would contribute fewer than 19 mg per serving, which is a very small amount for compounds like ashwagandha, where study doses in animals have been dramatically higher relative to body weight.
Does the Science Support Height Growth?
The most studied ingredient in TruHeight’s blend is ashwagandha. One animal study found that ashwagandha extract helped restore growth plate thickness in juvenile rats whose thyroid function had been chemically suppressed. In those rats, ashwagandha appeared to improve thyroid hormone levels, which in turn supported the cartilage cells responsible for bone lengthening. That’s a meaningful finding in a very specific lab scenario: rats with artificially induced hypothyroidism receiving 50 mg per kilogram of body weight daily.
Translating that to healthy human children is a significant leap. No published clinical trial has demonstrated that ashwagandha increases height in children or teens who have normal thyroid function. The same gap exists for the other ingredients in TruHeight’s blend. Spirulina is a nutrient-dense algae, and L-arginine plays a role in growth hormone release, but neither has clinical evidence showing it makes kids grow taller.
TruHeight did register a pilot study on ClinicalTrials.gov to evaluate its protein shake product in 32 children aged 4 to 17 over six months. The study is listed as completed, but no results have been posted. A 32-person pilot study without published results does not constitute the kind of evidence needed to support claims about height enhancement.
Growth Plates and the Age Factor
Height increases happen when growth plates, the bands of cartilage near the ends of long bones, are still active. These plates allow bones to lengthen throughout childhood and adolescence. Once they close and fuse with the surrounding bone, no supplement, nutrient, or hormone can restart that process. Growth plates typically close between ages 14 and 18 in girls and 16 and 20 in boys, though the timing varies.
TruHeight’s own website acknowledges this biology, stating that once growth plates close, “the significant increase in height has finished.” This creates an inherent limitation: even if the product’s ingredients could theoretically support growth, they would only have any chance of working in young people whose growth plates remain open. For adults, the biological window has closed permanently.
What “Not FDA Approved” Means for You
When a product is not FDA approved, it doesn’t automatically mean it’s dangerous. Calcium and vitamin D are well-established nutrients, and the individual ingredients in TruHeight are generally recognized as safe in normal amounts. What it does mean is that no independent government body has verified that TruHeight can do what it advertises.
The FTC’s action reinforces this point. The agency specifically found that TruHeight’s height-growth claims lacked adequate scientific support. Combined with the absence of published clinical trial data and the very small doses in the proprietary blend, the product’s central promise remains unproven. If you’re concerned about a child’s growth trajectory, a pediatrician can assess whether their growth pattern falls within the expected range and identify any underlying issues, like nutritional deficiencies or hormonal imbalances, that have well-established treatments.
