The products are namely Height Growth Premium Alpha and Height Growth Premium Pro.
Specializing in dietary supplements to boost children’s growth and development for nearly a decade, Icle Time recently announced that it has surpassed 980,000 cumulative customers.
Icle Time believes that this milestone solidifies its position in the market, and attributes it to the “deep trust” of parents earned through its continuous efforts to improve product quality.
“We will continue to set the standard for the children’s height growth market based on thoroughly verified data, ensuring that parents can choose us with confidence,” the brand said.
Beyond product sales, Icle Time’s platform offers a personalized growth solution that recommends the most suitable supplements and management methods according to a multifaceted analysis of the child’s gender, age, and lifestyle habits.
The brand stated that the renewed products focused on awakening a child’s hidden height potential through a newly incorporated core ingredient and scientific data.
Specifically, the ingredient is Hansamdeonggul (Humulus japonicus or Japanese hops) extract patented as HSy2, which was recognized by South Korea’s Ministry of Food and Drug Safety (MFDS) in July 2025 for its functionality in “helping with children’s height growth”.
Native to the East Asian region, Japanese hops is known for its strong reproductive and growth properties.
“HSy2 has been granted patents in eight countries worldwide, including Korea, the US, and Europe, underscoring its global recognition as a natural material capable of replacing growth hormones.”
Furthermore, it has obtained the highest safety rating in toxicity tests conducted in accordance with guidelines from the MFDS and Organisation for Economic Co-operation and Development (OECD).
In Icle Time’s premium products, HSy2 is combined with red ginseng to enhance immunity, and Rhodiola rosea extract to alleviate fatigue caused by stress.
The formulation also includes calcium, vitamins E, B1, and B2, chromium, manganese, and selenium, along with 19 types of premium auxiliary ingredients to manage height growth, immunity, and vitality simultaneously.
At the same time, the adoption of a liquid gel format is meant to facilitate ease of consumption as well as raise absorption rate.
“This format allows children to conveniently and deliciously recharge their energy with just one sachet a day, and in crowd-favorite blueberry and apple flavors.”
Effects proven in clinical trial
According to Icle Time, HSy2 has had its growth effects verified through rigorous human clinical studies.
In a 24-week randomized, double-blind, placebo-controlled clinical trial, a total of 150 children between the 3rd and 25th percentiles in height and between the ages of six and nine years were enrolled.
The participants were randomly assigned to the treatment or placebo group, with the former taking one pack of Humulus japonicus extract powder (700mg) per day and the latter consuming a placebo without HSy2 daily.
The results were statistically significant—the treatment group grew an average of 3.46cm, recording approximately 35% higher growth compared to the placebo group (2.56cm).
Notably, the daily growth rate of the treatment group was about twice as fast compared to the placebo group, and this difference was maintained until 24 weeks, indicating that the growth effect was sustained.
An analysis of the standard deviation score (SDS) by age also showed a continuous upward trend at both the 12-week and 24-week marks, which confirms a positive improvement trend across the overall growth trajectory rather than just short-term changes.
“These precisely verified and clear indicators serve as important grounds for building trust in our products among parents with demanding standards,” the brand reiterated.
