Busy brains, big feelings, new-term bedtime battles – and growing pains

Bedtime shouldn't drag on

New routines, earlier starts and a full day at school can leave kids wired rather than winding down come evening. And for a lot of kids, back to school lines up with a growth spurt – new shoes, more PE, more activity – which is exactly when growing pains tend to show up at night.

  • Late-evening restlessness
  • Trouble switching off after a busy school day
  • Growing pain that keeps them awake
  • Bigger feelings at bedtime

Here's what's actually happening with the growing pain: their bones can grow faster than their muscles, tendons and nerves can keep up with. That's the tension – not an injury, not illness, just growth outpacing everything around it. Paracetamol doesn't touch it. Magnesium does – it contributes to normal muscle function, signalling tight muscles to relax and release the tension causing the ache.

MADE FOR PICKY EATERS

Bedtime support only works if kids actually want to take it. Kids Calm Gummies are made with a soft chew, a natural raspberry flavour, and an easy evening format that fits into real routines.

  • Soft chew texture
  • Routine friendly
  • Natural raspberry flavour

WHAT'S INSIDE

195mg of active ingredients. 3 optimal daily doses. Everything they need. Nothing they don’t.

Magnesium

Magnesium

120mg

as Magnesium Citrate

Supports: Supports calm, relaxation, growing pains + winding down.
Why Tonic: We use magnesium citrate because it is a more absorbable form of magnesium than some standard forms. Plus, at 120mg per serving, it is a meaningful dose – not just a sprinkle for the front of pack. That's also why it's one of the first ingredients we formulate around: most kids' supplements microdose their magnesium, so it never actually makes a difference to the tension behind growing pains.
Chamomile

Chamomile

50mg

as Chamomile 5:1 Extract

Supports: Supports soothing busy minds and help kids settle into a calm, restful night.
Why Tonic: A gentle flower traditionally used in calming bedtime rituals.
Lemon Balm

Lemon Balm

25mg

standardised to 5% Rosmarinic Acid

Supports: Support relaxation and eases tension.
Why Tonic: We include lemon balm extract for its traditional use in relaxation and winding down. It gives the formula a gentler botanical edge at bedtime.

Reviews

Calm gummies

"I always used magnesium liquid as a a supplement for my 4 years to help with sleep. But wanted to try supplements with cleaner ingredients in them. Tonic calm gummies are great my 4 year old happily eats them and has a much calmer evening and sleeps through the night now too. Highly recommended these. :)"

— Samina H. (5/5)

Have actually helped bedtime!

"Bedtime has never been particularly easy in our house and we have honestly found that, though there are still tricky days, overall bedtime has been much smoother since we have added these to our bedtime routine. My daughter really likes the taste and we like that there are no nasty ingredients!"

— Emily K. (5/5)

Does what it says on the tin (glass jar)!

"I have found these to have a positive effect on my sons sleep patterns, he likes the taste to. He has ADHD and struggles to shut down at night but the magnesium and Ashwanganda seem to help alongside other strategies and supplements like Shrooms. I recommend giving it a try!"

— Phil (5/5)

Loved them

"We’ve been using Tonic vitamin gummies for the past month for my children, aged 5 and 7, and we’ve been really pleased with them. The kids actually enjoy taking them, which makes it so much easier than trying to convince them to take vitamins! They’re a great addition to their daily routine."

— Javeria B. (5/5)

Better Sleep

"I have been using these gummies for a month now and my children are sleeping so much better. My children struggled with going to sleep and going into a deep sleep both have been resolved with 2 gummies before bed."

— Stacey (5/5)

Kids love them

"It’s too early to see any firm results yet as we’ve only taken them for 2 weeks, but the kids love them and look forward to having a gummie every night."

— Natalie W. (4/5)

Brilliant!

"These are genius! Amazing taste! My daughter is more than happy to have two of these night time gummies as her pudding! I have to try not to eat them myself!!"

— Steph J. (5/5)

Amazing product!

"These completely stopped our toddlers nightmares and sleep walking. Noticed instantly when we ran out and didn’t have one for a couple of nights. He settles for a calm sleep with them. Incredible product!"

— Therese (5/5)

Great choice

"My daughter has really taken a liking to her gummies as part of her bedtime routine and she’s a little bit more relaxed."

— AKA (5/5)

Tasty gummies!

"My kiddo loves them, and so do I!"
