Where Height Happens
Children grow taller at the growth plates, thin layers of cartilage near the ends of their long bones. Cells in these plates continuously divide, enlarge, and harden into bone, adding length with each cycle.
This process continues only while growth plates remain open. Once they fuse, typically after puberty, height growth stops for good. The years before closure are the only window for gains in stature.
The Growth Engine: GH–IGF-1 Axis
Height growth is not random. It is driven by a signaling relay that runs from the brain to the bones.
- The hypothalamus signals the pituitary gland to release Growth Hormone (GH).
- GH travels to the liver, which responds by producing IGF-1 (Insulin-like Growth Factor 1).
- IGF-1 reaches the growth plates and stimulates cartilage cells to multiply and mature into new bone.
GH is released in pulses, with the largest burst occurring 30 to 90 minutes into deep sleep. During waking hours, IGF-1 carries on the sustained work of building bone.

Reading Your Child's Growth Chart
Understanding how growth works is one thing. Knowing where your child stands is the next step.
Pediatricians use growth charts to compare a child's height against peers of the same age and sex. The result is expressed as a percentile: the 50th means your child is right in the middle of the range; the 75th means taller than 75 percent of peers.
A single reading matters less than the trend over time. If your child's curve shifts noticeably, or annual growth falls below roughly 4 to 5 cm before puberty, it is worth raising the question with your pediatrician.
Everyday Habits That Matter
A handful of everyday habits shape the conditions in which growth happens.
- Nutrition: Protein, calcium, and vitamin D give bones the raw materials they need. A consistently varied diet matters more than any single food.
- Physical activity: Running, swimming, jumping rope, and similar moderate exercise support bone and muscle development. Adequate rest is part of the equation.
- Sleep: The body does much of its growth-related work overnight. Consistent, sufficient deep sleep keeps that rhythm on track.
- Emotional wellbeing: Chronic stress can disrupt sleep and appetite. A stable, supportive environment helps the whole system run smoothly.
A Different Approach to Growth Support
Good habits lay the foundation. But most conversations about children's height stop at inputs: eat more protein, take more calcium, add a vitamin. Building blocks matter. How well the body puts them to use matters just as much.
That is the idea behind IG5: a plant-based dietary supplement with a day and night formula, designed not to add hormones, but to work with the body's natural rhythm.
- Night formula: supports the body's overnight preparation for growth
- Day formula: supports bones and muscles in putting that preparation to work
