Yes, poor sleep quality is a hidden barrier to children's height growth.
As much as 70-80% of the body's growth hormone is released during deep sleep, particularly during the prime hours of 10 p.m. to 2 a.m. If children struggle to fall asleep, wake up frequently at night, or experience night terrors, their brains may be unable to enter deep sleep. Growth hormone production then drops significantly, making it difficult for them to grow even with plenty of nutrition during the day.

So, to help your child catch up in height, you need to improve their sleep first. Parents can choose growth supplements containing GABA or natural calming ingredients to help relax the brain and extend deep sleep.

OKAMI 大神 Sleep Calcium is designed for children who sleep poorly and grow slowly. It effectively helps children feel calm at night and extends their prime sleep period, allowing sufficient growth hormone to be released during the night.

Scientific research suggests that just before bedtime is the ideal time to take calcium, for two main reasons:

1. Maintaining nighttime blood calcium balance: Blood calcium levels reach their lowest point in the second half of the night. At this time, osteoclasts release calcium from bones to keep the body functioning, leading to bone loss. Taking calcium before bed provides a timely source of calcium to help protect bones.
2. Supporting sleep and relaxing muscles: Calcium is closely linked to relaxation of the brain and nervous system. Taking calcium before bed can calm the nerves, ease muscle and nervous tension built up during a child's day, and help reduce nighttime crying and leg cramps (growing pains).

To maximize the benefits of taking calcium before bed, consider a combination formula like OKAMI Deep Sleep Calcium. It combines high-quality calcium with Japan-patented Bonepep® (peptide growth factors), taking advantage of the nighttime peak in growth hormone secretion to precisely "lock" calcium and height-supporting factors into bones, delivering the dual benefits of sleep and height growth.

The body releases large amounts of growth hormone during deep sleep, which is especially important for children's height development.

Quality sleep supports natural growth and helps the body repair itself, so nutritional support for sleep should not be overlooked.

Helps improve sleep quality, stabilize mood, strengthen bone health, and build a solid foundation for children's growth from within.

No. Taking it during the day helps stabilize mood, improve attention, and enhance learning focus; taking it at night helps relax the nerves, shorten the time to fall asleep, enter deep sleep faster, and improve the quality of deep sleep without affecting daytime alertness.

GABA and tryptophan are natural nutrients with high safety profiles, widely used in sleep supplements for children.

Children aged 2 years and above can appropriately consume them, making them especially suitable for kids in critical growth periods for height.
