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.

Melatonin Can Cause Mood Disturbances, Irritability, and Nightmares. We don't use it.

A Healthier Approach

Most parents don't realize this. Melatonin is not a nutrient — it's the same hormone your child's brain is supposed to produce on its own. There are zero long-term studies on its effects on children's development, and the common side effects aren't small.

Our Nighttime Reset uses Magnesium Citrate and clinically-studied Suntheanine® instead — ingredients that work with your child's body, not override it.

✓ Hormone-free
✓ Clinically studied in kids
✓ No morning grogginess
✓ Supports natural sleep cycle

FAQs

Can my child take all of the bundled products together?

Absolutely, that's exactly how this bundle is designed. The multi is taken in the morning with breakfast. Nighttime Reset is taken 30–60 minutes before bed. The electrolyte sticks can be used at any point during the day. No overlap, no conflicts.

Why Suntheanine® instead of melatonin?

Melatonin is a hormone, it overrides your child's natural sleep signaling instead of supporting it. Suntheanine® is a patented, clinically-studied form of L-theanine that promotes relaxation and sleep quality in children without interfering with hormone development or causing next-day grogginess.

How long before we notice a difference?

Many parents report calmer bedtimes and less meltdowns within the first week. Suntheanine® works relatively quickly and can be felt in the same night. Nutritional benefits from the multi build over time with consistent daily use, typically 2–4 weeks for measurable mood and behavior changes.
