My son is VERY picky but gets so excited to eat these. I unfortunately tried hiya first & wasted money because he would not eat them. I love that these are a gummy soft chewable.

Gummies with a textured surface on a white background

Calms the Nervous System

Yummy strawberry flavored gummies make bedtime a fun experience for kids. A healthy nervous system is key to balanced moods and that' why the main ingredient is magnesium. This essential mineral is shown to support brain health, nervous system function and balanced moods for brighter days and calmer nights. 

A Signal to Sleep

Your body needs magnesium to relax. It eases tension in your muscles, slows a busy mind, and signals your body that it's safe to sleep. Most people don't get enough of it, and their nights show it.

Calmer Moods

Magnesium supports brain health, nervous system, and relaxed moods.

No Melatonin Hormones

Just science-backed ingredients for better sleep and moods.
