This is what surprises parents the most when they discover it.
75% of growth hormone is released during deep sleep. Not during the day. Not at school. At night, while sleeping.
If your child doesn't reach deep sleep due to stress, screens, or lack of magnesium, that hormone simply isn't released. That night is lost forever.
Magnesium is the nutrient that activates deep sleep. And ashwagandha reduces the cortisol that blocks it. Without both, the nighttime growth window closes every night without anyone seeing it.
