Endless Bedtime Battles?

It seems like every night, bedtime is a struggle for our kids! But those bedtime battles could be a sign of a bigger issue – magnesium deficiency. In fact, low magnesium affects more than 50% of people, impacting the nervous system and disrupting our kid’s mood and sleep. Which means getting those magnesium levels up (and keeping them up!) are key to better bedtime habits. That’s why we created Kids’ Nighttime Reset – a calming magnesium gummy that’s hormone-free.*

Restful Sleep

Getting your kid to fall and STAY asleep may be a battle, but with magnesium and Suntheanine®, your kid can snooze through the night. These clinically studied ingredients help calm the nervous system and produce neurotransmitters needed for quality sleep.

Balanced Moods

A healthy nervous system is key to balanced moods. That’s why Nighttime Reset includes magnesium. This essential mineral is shown to support brain health, nervous system function and balanced moods for brighter days and calmer nights.

Say No to Taking Melatonin Hormones

Did you know melatonin is a hormone? A lot of people don’t! Yet, tons of people turn to it every day to help their kids sleep. But, there are actually no long-term studies on the effects melatonin has on children and their development. Beyond that, the common complaints are endless:

• Morning grogginess 

• Daytime sleepiness 

• Restless nights 

• And even nightmares!

We say no to melatonin hormones for our Nighttime Reset gummies. Instead, our bedtime superstars are Magnesium Citrate and Suntheanine®. 

Comparison chart shows First Day Life Inc.'s Kids’ Nighttime Reset Magnesium Add-On with calming ingredients and five green check marks; Other brands have five red Xs. Highlights restful sleep, 55M gummies sold in 2024, and First Day’s advantages.

Kids' Calming Magnesium FAQs

What's are the ingredients?

No sneaky melatonin hormones here! We use high-quality ingredients backed by science to give your kids a good night’s sleep.

Magnesium Citrate: An essential mineral that supports mind and body relaxation, balances mood, and supports nighttime relaxation. We use a 100% chelated format that is more bioavailable, for maximum absorption.*

Suntheanine® L-Theanine: Clinically studied ingredient shown to promote relaxation, improves sleep quality, and decreases stress and anxiousness for kids, specifically.

Why do you have less than 100% of daily values?

Remember the old adage "more isn't always better"? Many vitamins today use cheap chemicals that our bodies can't absorb in amounts that are much higher than we actually need! In the long term, taking these sorts of vitamins can be harmful to health because our bodies have a tough time getting rid of the excess.

Take plants as an example. Overwatering your plants can damage their roots, wilt the leaves, and ruin their growth. That's why First Day focuses on being a nourishing vitamin filling in the gaps, not overloading you with nutrients.

So, we've consciously formulated our vitamin around what we most commonly lack. Then we made our gummy to fill the gaps in our everyday needs with the finest ingredients.

What else is different about First Day?

We set out by asking the unaddressed questions in the industry. What are supplements really doing for us? Why are they made the way they are?

We found the average multivitamin uses outdated science from 50 years ago.

To separate truth from fiction, our team of experts investigated thousands of clinical studies. That’s why we use the latest science and source the most absorbable ingredients from all around the world so your vitamins are actually working for you and your health.

Should I subscribe if I've never tried First Day before?

Healthy habits are hard to start let alone maintain! We wanted to make it as simple as one-click to building healthy foundations. With your subscription, you get a discount on every order for being a loyal First Day family member! Plus, cancelling a subscription is easy.

For every order, we also have a satisfaction guarantee so you can rest assured knowing we'll always have your back!

Which scientific studies does First Day look at?

Micronutrients, absorption rate, and more! We've combed through the scientific studies so that you don't have to. But if you want to peruse, check out these scientific studies for yourself:

My son is autistic and also has ADHD. These have helped him calm down and wind down before bedtime. The hyperactivity really slows down and my son is able to just relax with me, do our nightly routine, and go to sleep. These are expensive but worth it!!

Calming effect

This product is great for my son who I have been through a lot of products. I was looking for something to just relax his body and this product is amazing. I honestly do not use it at nighttime but give him 2 before school and he is doing so much better and getting more happy faces now.

Less fussiness than usual

My son is 8 and is non verbal and has developmental delays. Sometimes bedtime routines get interrupted by bursts of energy and these gummies helped lessen those outbursts at bedtime. It’s hard to say since he’s nonverbal if there were any other side effects but I didn’t notice any. Just less fussiness than usual.

Falls asleep much faster!

First OMG, tastes absolutely delicious! Both my boys 8 and 10 love the taste and so do I! My 10 year old gets anxiety on Sunday nights when the weekend is over, these help calm him and get him off to sleep. My 8 year old usually takes the longest to fall asleep which can be very frustrating. Since starting these gummies he falls asleep much faster!

The good stuff

When I switched my grandson who is on the spectrum to a less expensive company, he refused to eat them! Wouldn't even give them a chance! As soon as they hit his tongue, out they came!
When I returned to first day, his words to me were, "MIMI! You got me the good stuff again!"
Quite the endorsement from a 7 year old on the spectrum!
