How to Determine If a Child Has Entered the "Golden Period for Growth"?
5 Key Points to Pay Attention To!
30 July 2025

The "golden period for growth" is a critical stage for a child's rapid height increase, typically occurring before and during puberty when the growth plates in the bones are still open and growth hormone secretion is at its peak, making it the optimal time to boost height. However, many parents are unsure how to identify whether their child has entered this stage or how to provide scientifically-backed nutritional support. This article will detail five key points to determine if a child is in the "golden period for growth," helping parents seize this golden opportunity to help their child surpass height limitations.
What is the "Golden Period for Growth"?

Five Key Signs to Determine If a Child Has Entered the Golden Period for Growth
To determine whether a child has entered the golden period for growth, parents need to closely observe their child's physiological and behavioral changes. Below are five key points to help parents accurately identify this stage:
1. Significant Acceleration in Height Growth
Children entering the golden period for growth typically experience a height increase of 5-10 centimeters per year, with boys potentially reaching higher rates (around 10 cm/year) and girls slightly lower (around 8 cm/year). Parents should measure their child’s height monthly, and if consistent growth is observed over several months (e.g., 0.5-1 cm per month), this is a strong indicator of entering the golden period. It is recommended to use a fixed measuring tool (such as a wall-mounted height chart) and measure at a consistent time (e.g., in the morning) to ensure accurate data.
2. Sudden Increase in Appetite and Food Intake
Rapid growth requires substantial energy, and children may exhibit a significant increase in appetite or frequent hunger. For example, a child who previously ate one bowl of rice might suddenly need two or even request extra portions. This is because the body is storing energy for bone development and muscle growth. A noticeable increase in dietary needs could be a sign of the golden period for growth.
3. Increased Sleep Needs and Improved Sleep Quality
Growth hormone is primarily secreted during deep sleep, particularly between 10 p.m. and 2 a.m., which is the peak secretion period. Children in the golden period for growth may require longer sleep durations (8-10 hours per night) or show signs of falling asleep more easily and sleeping more deeply. Parents can observe whether their child sleeps more than usual or appears more refreshed after sleep, which serves as indirect evidence of accelerated physical growth.
4. Emergence of Secondary Sexual Characteristics
The golden period for growth typically coincides with puberty, accompanied by the appearance of secondary sexual characteristics. Girls may begin to develop breasts or experience their first menstrual period, while boys may notice a deepening voice, the appearance of an Adam’s apple, or increased body hair. These changes indicate an active endocrine system, often associated with rapid height growth. If parents observe these signs, they should pay special attention to their child’s growth status.
5. Medical Assessment of Bone Development
For a more scientific approach, parents can take their child to a hospital for an X-ray examination to assess the condition of the growth plates in the bones. Active growth plates indicate that the child is still in the growth phase, while closed growth plates suggest that height growth is nearing its end. Additionally, doctors may use a bone age test to evaluate the child’s developmental stage, helping to determine whether they are in the golden period for growth. This is the most precise method for identifying the golden period, particularly suitable for children with slow height growth or developmental concerns.

Frequently Asked Questions
🔍What age group is best suited for this product? It’s ideal for ages 5–22, with the best results seen before puberty (boys 12–16, girls 11–15), when growth plates are still open.
Recommended Dosage:
5-15 years: Once daily, two tablets each time
16 years and above: Twice daily, two tablets each time
🔍Can Taking Height Growth Products After Age 18 Still Promote Height Increase? Yes, taking height growth candy after age 18 can still promote height increase! Although most people's growth plates gradually close after puberty, studies show that some individuals may still have open growth plates before age 22, retaining growth potential. Clinical trials of the height growth candy indicate cases of height increase in participants under 22 years old after use.
